Millions of People in Canada Are Finding AI-Enabled Support for Mental Health Effective Amid Ongoing Questions Around Trust.

(OTTAWA) July 8, 2026 — New polling shows approximately six million people in Canada used AI-enabled tools for mental health support in the past year and most find them effective. Today, the Mental Health Commission of Canada (the Commission), in partnership with Mental Health Research Canada (MHRC) and Pollara Strategic Insights, releases the first nationally representative data on how people in Canada engage with digitally supported mental health tools, including AI and virtual care, across every province and demographic.

Quick Facts:

  • 1 in 7 people in Canada used AI mental health tools in the past year
  • Three out of four who used AI and virtual mental health services found them effective for their well-being
  • Only 14 % trust AI tools, just 2% trust them completely
  • 40 % of AI users said they were more likely to seek professional care
  • Nearly half (45%) who accessed mental health care did so virtually, in whole or in part

WHY IT MATTERS

People in Canada are turning to AI as a convenient way to access mental health support.  AI-enabled tools may offer greater convenience and accessibility. Among those surveyed, AI is being used because it is:

  • Free or low-cost; 46% of AI users cite this as the reason they use it during a time when financial stress is itself a cause for anxiety.
  • Always available; 44% of AI users cite 24/7 access.
  • Immediate and convenient; it can be used from anywhere without travelling or waiting for an appointment. For someone in rural Canada, it saves time and travel costs.
  • Seemingly private; 39 % of AI service users cite private, anonymous support as a reason for use, while privacy and data protection remain key public concerns.

AI is most used for general well-being (42%), companionship (36%), and mild-to-moderate stress (36%), and 40% of AI users said they were more likely to seek professional care.

WHO IS USING IT AND HOW MUCH DO THEY TRUST IT?

Use is higher among people in Canada under 35 (27%; 29% among men aged 25–34), newcomers to Canada (28%), racialized people in Canada (23%), and 2SLGBTQI+ communities (20%), populations that may experience greater barriers to traditional care.

Overall, trust remains low, particularly for AI-enabled tools, where only 2% of people in Canada trust them completely. People in Canada over 55 show the lowest adoption and trust.

VIRTUAL CARE: EFFECTIVE AND MORE TRUSTED BUT FALLS SHORT OF IN-PERSON SERVICES

45% of people in Canada who used mental health services in the past year did so virtually, with 75% reporting positive outcomes. However, nearly 1 in 3 prefer a hybrid model that combines virtual and in-person services. The data signals what people in Canada need: well-designed tools for safer digital mental health care that they can trust.

THE COMMISSION OFFERS GUIDANCE FOR THE DIGITAL MENTAL HEALTH ERA

The Commission is Canada’s trusted resource for safe digital mental health — assessing apps and tools, setting evidence-based standards, and leading the national conversation on guidance for AI in mental health and substance use health care.

As virtual services and AI-enabled tools continue to expand rapidly across the mental health landscape, there is a growing need for evidence-based insight into how people in Canada engage with, understand, and perceive them. The Commission partnered with MHRC to leverage their ongoing national polling initiative and provide timely insights into usage, attitudes, and concerns related to e-mental health and AI.

The polling is clear: people in Canada want to close the gap between availability and trust. The Commission is working with the Canadian Centre on Substance Use and Addiction and collaborators, provincial governments, technology developers, and health system partners to establish guidance for AI.

“Six million people in Canada have already used AI for mental health support and most found it convenient and effective for their well-being. It is critical that AI is safe and equitable to increase public trust and reduce harms.” – Lili-Anna Pereša, President and Chief Executive Officer, Mental Health Commission of Canada

“The people turning to digitally-supported mental health tools are often those facing some of the greatest barriers to care. Making sure these tools are safe, effective, evidence-based and human-centred is a matter of equity. Ongoing research is essential to understanding where they help and where safeguards are needed.”– Akela Peoples, Chief Executive Officer, Mental Health Research Canada

STAT+: Trump administration pursues more durable changes to science policy after setbacks in court

Thousands of federal civil servants who academic researchers see as partners in conducting their work were fired. An unprecedented number of scientific projects funded by previous administrations were terminated. Universities were pressured to abandon diversity programs and work to curb health disparities. On a Friday evening, the government tried to push through a dramatic change to how it reimburses universities for research overhead. 

All of these actions in the first year of the Trump administration were rapidly challenged in federal court, in many cases resulting in the administration having to walk back policies because they ran afoul of the Administrative Procedures Act, which governs how new policies and regulations are rolled out.

Andrew Twinamatsiko, who is director of the Center for Health Policy and the Law at Georgetown University and runs a health care litigation tracker, describes what happened last year as “tempests that we could weather” until there’s a new administration, when “there can be ways of reverting back to the baseline that we used to have.”

Drug Candidate Shows Early Promise for Treating Alzheimer’s Damage

A drug candidate developed at King’s College London boosts DNA repair and reduces neuronal damage, as well as lowering neuroinflammation and could become a new treatment option for people with early stage Alzheimer’s disease in the future.

Writing in the journal FEBS Open Bio, lead author Jonathan Corcoran, PhD, a professor at King’s College London, and colleagues report results of a study carried out in a mouse model of Alzheimer’s disease that tested KCL-286, a retinoic acid receptor-beta agonist, and showed it had beneficial effects in the animals.

As Alzheimer’s disease develops, amyloid-beta accumulates and suppresses the brain’s natural retinoic acid signaling. This, as well as other factors, leaves neurons increasingly unable to repair DNA damage. The unrepaired damage then triggers microglial and astrocyte overactivation, which contributes to further neuronal injury in a self-reinforcing loop.

Mice treated with KCL-286 had significantly fewer DNA double-strand breaks in neurons than untreated mice, something seen in Alzheimer’s patients. They also had increased neuronal expression of BRCA1 protein, a DNA repair and tumor suppressor protein, suggesting KCL-286 partly works by ramping up the brain’s own repair machinery. In certain cancers, a BRCA1 mutation results in reduced or absent functional protein, which increases cancer risk over time.

KCL-286 also seemed to reduce inflammation in the brain of treated mice. Microglia and astrocytes were both abnormally enlarged and activated in the animals before treatment. However, after treatment the size and shape of these cells went back towards normal, in other words, calming dangerous inflammation without getting rid of the cells.

“We think of the drug as repairing potholes in a road—once the damage is fixed, normal traffic can flow again and the system settles down. By repairing the underlying damage, we can allow the system to reset,” said Corcoran in a press statement.

This is an early stage study and still needs to be tested in humans, but KCL-286 has already completed a Phase I trial in healthy human volunteers with no drug-related adverse events and is known to cross the blood-brain barrier efficiently. This is because the drug candidate is also being tested for treatment of spinal cord injury, hence the earlier Phase I study.

Both acute spinal cord injury and chronic neurodegeneration in Alzheimer’s involve accumulation of DNA double-strand breaks in neurons. In the former this is caused by the mechanical trauma and subsequent inflammation, whereas in the latter it builds up gradually over years.

The lack of side effects seen in the Phase I study is also important for KCL-286’s development as a possible Alzheimer’s treatment, as two earlier, non-selective retinoid drugs tested for treatment of Alzheimer’s caused side effects because they hit multiple off target receptor subtypes. KCL-286’s selectivity for the retinoic acid receptor-beta is designed to avoid this.

“Together with its favorable human safety profile, the data support further investigation of selective retinoic acid receptor-beta agonism as a therapeutic strategy for modifying pathogenic processes associated with Alzheimer’s disease,” conclude the authors.

The researchers think that if KCL-286 reaches the clinic early treatment is likely to be key to success. They also note there is potential for this type of therapy to be used in combination with approved Alzheimer’s treatments like lecanemab, which act to reduce harmful amyloid beta in the brain.

Novartis to Acquire Myricx Bio for Up to $1.5B, Adding Cancer-Fighting ADC Payload Platform

Novartis has agreed to acquire Myricx Bio, a London-based developer of next-generation antibody-drug conjugates (ADCs), for up to $1.5 billion in a deal designed to bolster the buyer’s oncology pipeline with a next-generation ADC payload platform designed to fight cancer.

Privately-held Myricx specializes in developing ADCs that use N-myristoyltransferase inhibitor (NMTi) payloads, an approach designed to deliver a differentiated cancer-killing payload directly to tumor cells. Myricx says its ADC approach holds the potential to address limitations of TOPO-1 inhibitors, tubulin inhibitors, and other commonly used ADC payload classes—ranging from toxicity to healthy cells, to tumor resistance, to dose-limiting adverse events.

The acquisition deal is designed to combine Myricx’s two lead ADC assets and next-generation first-in-class NMTi payload platform with Novartis’ expertise in developing cancer therapies.

According to Myricx Bio, preclinical data suggests that its NMTi payload may have broad activity across multiple solid tumors, including TOPO-1-resistant models, and may enable more effective use of ADCs in settings where existing payload classes have limitations. NMT is an enzyme responsible for the addition of myristic acid, a 14-carbon fatty acid, to the N-terminus of multiple proteins that are crucial for cancer cell survival.

“ADCs have become an important part of cancer treatment, but there remains a clear need for new payload mechanisms to overcome resistance and expand their impact for patients,” Fiona Marshall, PhD, Novartis’ president of biomedical research, said in a statement. “Myricx Bio has developed a promising NMTi payload platform with a differentiated mechanism that could broaden the use of ADCs across multiple tumor settings.”

Marshall added that the Myricx Bio acquisition “reflects our strategy to scale innovative platforms, as we have with radioligand therapies, to deliver more durable, transformative treatments for patients.” In February, Novartis announced plans to build a 46,000-square-foot radioligand therapy (RLT) manufacturing site in the Dallas-Fort Worth suburb of Denton, TX.

Novartis investors reacted by sending its shares traded on the SIX Swiss exchange down 2% Monday, from CHF 127.92 ($157.69) to CHF 125.10 ($154.22). Novartis’ American Depositary Shares (ADSs) traded on the New York Stock Exchange dipped 3%, from $159.90 to $155.08 as of 10:13 a.m. ET

Mohit Rawat, Myricx Bio’s CEO

Until now, Myricx has said little about its two lead NMTi-ADC candidates, except to disclose on its website that it is prioritizing one that targets B7-H3 and the other, HER2, “based on compelling preclinical efficacy and safety data across multiple solid tumor-associated antigens and cancer cell types.”

Novartis agreed to shell out $1.1 billion cash upfront plus up to $400 million tied to achieving milestones. The transaction is expected to close in the second half of this year, subject to satisfaction or waiver of customary closing conditions, including regulatory approvals.

“Transformative promise”

“We are delighted that Novartis recognizes the transformative promise of our NMTi-ADC platform to deliver this next-generation of potential first-in-class, highly differentiated ADC therapeutics,” stated Mohit Rawat, Myricx Bio’s CEO. “Together with Novartis, we look forward to building upon our work to transform the landscape of cancer treatment.”

Rawat joined Myricx last year with the goal of steering the company through preclinical development and its next stage of growth.

Founded in 2019, Myricx Bio was spun out from Imperial College London and the Francis Crick Institute by Ed Tate, PhD; Roberto Solari, PhD; and Andrew Bell, PhD, with support from Cancer Research UK, as well as seed investment from Brandon Capital and Sofinnova Partners.

Myricx’s co-founders and their collaborative teams discovered that NMT played a vital role in maintaining multiple critical, diverse cellular processes in cancer cells, including vesicle trafficking, growth factor signaling, cancer cell survival, mitochondrial biogenesis, and cancer cell metabolism.

Under CTO Robin Carr, PhD, Myricx Bio raised £90 million ($114 million) in a Series A financing in mid-2024 led by Novo Holdings and Abingworth, joined by British Business Bank, Cancer Research Horizons, Eli Lilly, and existing investors. This enabled the company to scale its operations and expand the team to rapidly advance its pipeline.

The planned acquisition of Myrocx Bio is Novartis’ third major deal this year focused on boosting its cancer pipeline.

On June 24, Antares Therapeutics announced it would receive $105 million upfront from Novartis through a strategic collaboration to discover, develop, and commercialize small molecule therapies against promising but historically undruggable oncology targets. Novartis also committed to paying Antares up to $1.8 billion tied to achieving additional option exercise, development, regulatory, and commercial milestones, as well as tiered royalties on global net sales.

And in March, Novartis committed up to $2 billion upfront toward acquiring Pikavation Therapeutics, a subsidiary of Synnovation Therapeutics that specializes in developing PI3Kα inhibitor programs designed to treat forms of cancer. Novartis also agreed to pay up to $1 billion in payments tied to achieving development, regulatory, and commercial milestones.

Germline‑Targeting HIV Vaccine Generates Broadly Neutralizing Antibodies in Primates

For years, HIV has resisted traditional vaccine strategies. The virus’s staggering antigenic diversity, rapid mutation rate, and glycan‑shielded envelope have made it extraordinarily difficult for the immune system to generate antibodies capable of recognizing HIV’s vulnerable sites. Yet a small number of people living with HIV do develop broadly neutralizing antibodies (bnAbs)—rare antibodies that can target conserved regions of the virus despite its shape‑shifting defenses. These bnAbs have long been viewed as templates for next‑generation vaccine design, but reliably eliciting them through vaccination has remained out of reach.

A team led by scientists at La Jolla Institute for Immunology (LJI) and Scripps Research now reports a potential breakthrough. In a study published in Nature, the researchers demonstrated that a germline‑targeting HIV vaccine can elicit bnAbs in outbred nonhuman primates. The study is titled, “Vaccination elicits HIV broadly neutralizing antibodies in primates.”

Germline targeting represents a fundamentally different vaccine design philosophy. As the authors wrote, it is “a conceptually radical vaccine design approach to elicit bnAbs, aiming to prime rare bnAb‑precursor B cells possessing pre‑determined human genetic and structural features shared with template bnAbs, and then guide B cell affinity maturation to potent bnAb evolution with heterologous boosters.”

To test this strategy, the team engineered protein immunogens that mimic key HIV envelope structures known to initiate bnAb development. Rhesus macaques received a priming immunogen designed to activate naive B cells, followed by a sequence of booster shots that guided those cells through the necessary maturation steps. “This series of vaccinations will guide, or ‘walk,’ a B cell from its naive state to its broadly neutralizing state,” explained co-first author and LJI instructor Patrick Madden, PhD.

The researchers reported that bnAb‑class memory B cells emerged in at least half of the animals, and “serum bnAb activity developed in 44% of animals.” In the strongest responder, bnAb titers reached titers “expected to confer protection against diverse HIV isolates,” according to the authors.

Human translation is already underway. The priming immunogen used in this study has been evaluated in the HVTN 144 trial and is currently being tested in the Phase I IAVI G004 trial. Shane Crotty, PhD, LJI professor and CSO, noted that the approach may perform even better in humans due to immunogenetic factors.

The next challenge is optimization—refining booster sequences, improving response rates, and ultimately demonstrating protection. But this study provides long‑sought proof of principle, according to the authors: “Germline-targeting vaccines can reproducibly elicit prespecified classes of bnAbs to prespecified epitopes under endogenous conditions, supporting further optimization of this approach for HIV vaccine development.”

Vertex Eyes Expansion Beyond Cystic Fibrosis with Planned $10B Crinetics Buyout

Vertex Pharmaceuticals has agreed to acquire Crinetics Pharmaceuticals for $10 billion cash, the companies said, in a deal that would expand the buyer’s rare disease portfolio beyond its anchor indication of cystic fibrosis (CF), by adding an approved treatment and a pipeline anchored by two Phase III candidates, all predicted to generate more than $5 billion in annual revenue.

Based in San Diego, Crinetics focuses on discovering, developing, and commercializing therapeutics for endocrine diseases. The company’s first marketed drug Palsonify® (paltusotine), an oral SST2 agonist, was approved by the FDA in September as the first and to date only once-daily oral therapy for adults with acromegaly, a debilitating condition which affects an estimated 20,000 Americans. Palsonify won European Commission approval in April and is under review by regulators elsewhere in the world.

Palsonify has enjoyed rapid uptake among acromegaly patients, with Crinetics reporting the drug generated net product revenue of $10.3 million during the first quarter, with 232 patients enrolling for treatment. Approximately 70% of patients treated with Palsonify at the end of Q1 were on reimbursed therapy—reflecting payers increasingly agreeing to cover the treatment, according to the company.

Within the first two quarters of its U.S. launch, Palsonify was prescribed by 263 unique healthcare providers.

Under its generic name paltusotine, the drug is in Phase III study for a second indication of carcinoid syndrome, a rare condition resulting from neuroendocrine tumors.

‘Excellent strategic fit’

Reshma Kewalramani, MD, Vertex Pharmaceuticals CEO and President

“Crinetics is an excellent strategic fit for Vertex, with its focus on serious diseases in specialty markets with significant unmet need, well-understood causal human biology, and potentially best-in-class medicines that could deliver transformative benefit to patients,” Reshma Kewalramani, MD, Vertex’s CEO and president, said in a statement. “We believe Vertex can build on the strong momentum of the Palsonify launch by applying our experience in commercializing medicines for rare genetic diseases.”

Crinetics investors agreed, roaring their approval of the pending acquisition as the company’s shares all but doubled in early trading Tuesday, zooming 99% to $83.54 as of 10:28 am ET from yesterday’s closing price of $42.03. Vertex shares dipped 2% to $516.48 from $529.59 at Monday’s closing bell.

Also in late-stage development is Crinetics’ lead pipeline candidate atumelnant, an oral adrenocorticotropic hormone (ACTH) antagonist now under development for congenital adrenal hyperplasia (CAH) and ACTH-dependent Cushing’s syndrome.

In classic CAH, a rare chronic genetic disease with 17,000 addressable patients in the U.S., atumelnant is in a pair of clinical trials. One is a Phase III study in adults with the most common cause of the disease, 21-hydroxylase deficiency (21-OHD). The study’s estimated primary completion date is May 2027 (NCT07144163). The other trial is a Phase II/III study in children ages one to <18, which has an estimated primary completion date of March 2030 (NCT07159841).

Earlier Phase II studies of atumelnant showed that patients treated with the therapy achieved near normalization of excess androgen levels on physiologic replacement doses of glucocorticoids—a therapeutic profile that Crinetics  has said positions atumelnant to become the leading treatment for people with CAH.

Atumelnant (formerly CRN04894) is also being developed for ACTH-dependent Cushing’s syndrome, and is under study in a Phase Ib/IIa open-label, multiple-ascending dose exploratory study (NCT05804669) designed to evaluate safety, tolerability, pharmacokinetics (PK), and pharmacodynamic biomarker responses associated with the treatment.

‘Significant potential’

“We are also excited by the significant potential of atumelnant to transform the treatment landscape for CAH, setting a new standard of care where patients do not have to choose between managing their excess adrenal androgens and enduring the side effects of high-dose steroids,” Kewalramani said.

One analyst said a Vertex buyout would be good news for Crinetics.

“This is a solid outcome for CRNX, given stock pressure from the near-term Palsonify launch (generally slow and steady launch but (+) [positive] progress by CRNX so far) and the fact that key Phase III catalyst for CAH isn’t until late 2027/28,” Jefferies equity analyst Dennis Ding wrote today in a research note.

In a regulatory filing yesterday, Crinetix shared an email it sent to employees, stating: “We have always been confident in the ability of Crinetics to achieve our plan and were not actively looking to sell the company when Vertex approached us. However, after careful consideration, our board unanimously determined that the transaction is in the best interests of our shareholders.”

Crinetics’ pipeline of more than 10 disclosed candidates includes:

  • CRN09682, a Phase I nonpeptide drug conjugate candidate being developed to treat somatostatin receptor 2 (SST2) expressing neuroendocrine tumors and other SST2 expressing solid tumors.
  • Discovery-phase preclinical programs focused on endocrine targets that include thyroid stimulating hormone (TSH), parathyroid hormone (PTH), somatostatin receptor 3 (SST3), growth hormone (GH), glucagon-like peptide 1 (GLP-1), and glucose-dependent insulinotropic polypeptide (GIP), as well as GPCR-targeted oncology indications.

Vertex said the deal was expected to contribute immediately to revenue growth via the ongoing launch of Palsonify, which the company says has blockbuster (greater than $1 billion in annual sales) potential in acromegaly. Longer term, Vertex says, atumelnant could also generate multiple billions of dollars in CAH, with additional revenue potential in Cushing’s syndrome.

$5B revenue forecast

R. Scott Struthers, PhD, Crinetics’ Co-founder and CEO

At peak year, Palsonify and atumelnant could deliver more than $5 billion in combined annual revenue, Vertex said, and thus contribute toward its goal of delivering sustained double-digit revenue growth, plus industry leading operating margins. The transaction is expected to add to non-GAAP operating income as of 2029.

Jefferies analyst Ding commented that atumelnant in CAH is expected to generate the largest share of the projected $5 billion, as in $2 billion to $3 billion, plus another $1 billion to $2 billion for Cushing’s syndrome–with the remaining $1 billion to be generated by Palsonify in acromegaly.

Scotiabank analyst Louise Chen told Reuters: “The deal ​adds a fifth vertical, endocrinology, which helps diversify VRTX’s concentration in CF.”

That concentration has proven lucrative for Vertex: During Q1, CF treatments generated $2.915 billion in total revenues, 98% of the company’s total revenue of $2.987 billion.

Vertex has agreed to acquire all outstanding shares of Crinetics common stock for $85 per share cash, in a deal valued at $8.8 billion net of estimated cash acquired. Vertex said it expects to finance the acquisition using a combination of cash on hand and debt, supported by $4.5 billion of fully committed bridge financing from Bank of America and Morgan Stanley Senior Funding.

Vertex finished the first quarter with cash, cash equivalents, and total marketable securities of $13 billion, up from $12.3 billion as of December 31, 2025. The company attributed the increase primarily due to cash flows from operating activities, partially offset by repurchases of Vertex’s common stock.

The transaction is expected to close in the third quarter subject to customary closing conditions, including receipt of regulatory approvals and approval by Crinetics shareholders.

“Nearly 18 years ago, we founded Crinetics with a clear goal of transforming the lives of patients living with endocrine-related diseases. Today marks a historic milestone as we embark on this next chapter with Vertex,” stated R. Scott Struthers, PhD, Crinetics’ co-founder and CEO. “Vertex’s global infrastructure and commercial footprint will serve to amplify the reach of our science and allow us to maximize the impact of Palsonify, atumelnant and our pipeline.”

Evaluating Wearable Devices for Remote Monitoring in Psychosis: Pilot Study Nested Within the CONNECT Cohort Study

Background: Digital remote monitoring technologies, including smartphones and wearables, offer promising avenues for early detection of psychosis relapse. However, selecting devices that are acceptable to participants and produce high-quality data remains challenging. Objective: The aim of this nested pilot study was to assess the acceptability and data quality of 3 commercially available wearable devices in people with psychosis recruited to the CONNECT cohort study. Methods: Participants recruited to the CONNECT study before July 31, 2024, were included in the pilot study and selected 1 of 3 wearable devices: a Fitbit Charge 5, Samsung Galaxy Watch 5, or Apple Watch SE. Baseline demographics were compared between device groups. Acceptability of devices to participants was assessed through a Wearable Device Satisfaction Questionnaire after 3 months of use, with the proportion of positive responses to each question calculated and compared. Data completeness was also assessed by calculating the number (and percentage) of valid days of step count, heart rate, and sleep data, and comparing between groups. Data quality was assessed through summarizing the amount of troubleshooting required, additional metrics available from the wearables, and continuity of data completeness by calculating the proportion of participants with at least 3 days of heart rate data per week for the first 20 weeks of follow-up. Predefined criteria were used to determine the next steps for the wider CONNECT study: if one device was superior, this would be selected; if none were found to be superior and the Fitbit was found to be noninferior, then Fitbit would be retained. Results: Of the first 107 participants recruited to CONNECT, 105 were included in the pilot study evaluation. The Samsung Galaxy Watch was selected most frequently by participants (46/105, 43.8%), followed by the Apple Watch (27/105, 25.7%), and Fitbit Charge (23/105, 21.9%). Differences in participant demographics were observed across device groups. Self-reported acceptability after use did not differ substantially between devices. However, in terms of data completeness, the median proportion of valid heart rate data days was significantly lower for Samsung Galaxy (median 31.2%, IQR 8.5%-46.0%) compared to Fitbit (median 80.1%, IQR 26.7%-95.0%; =.003) and Apple Watch (median 49.3%, IQR 21.5%-86.0%; =.02). There was no significant difference between Fitbit and Apple Watch. Similar patterns were observed for step count and sleep data. The Samsung Galaxy Watch required more frequent troubleshooting for data flow issues and lacked additional physiological metrics, available from the other devices. Conclusions: Due to comparatively lower data quality and technical performance, the Samsung Galaxy Watch was discontinued for use in the subsequent phase of the CONNECT study. The study highlights the importance of incorporating nested evaluations of devices in long-term research.

Loneliness From the Digital Mental Health Practitioners’ Perspective: Thematic Analysis of Semistructured Interviews

Background: Loneliness is a prevalent concern across the United Kingdom. While validated scales exist to quantify the severity of loneliness across populations, there remains a gap in understanding how loneliness manifests and is addressed within therapeutic practice. Given the associated stigma surrounding loneliness, practitioner perspectives offer crucial insights into how clients express loneliness within digital therapeutic environments. These insights can inform more nuanced conceptualizations of loneliness. Objective: This study aimed to gather the practitioners’ perspectives on loneliness within a digital therapeutic context and were defined as follows: (1) understand how practitioners identify loneliness concerns, (2) identify how loneliness is elicited in digital mental health interventions, and (3) identify co-occurring themes (such as grief, shame, and social disconnection) that signal loneliness concerns in client communications within digital therapeutic environments. Methods: Semistructured interviews were conducted with 9 practitioners. Participants included specialists in grief counseling, lesbian, gay, bisexual, transgender, and queer or questioning plus support; and digital mental health therapists. Interview transcripts were analyzed using thematic analysis, using an inductive, data-driven approach to allow themes to emerge from participant accounts rather than fitting data to preexisting theoretical frameworks. Results: The following four themes were identified: (1) Conceptualizing Loneliness: practitioners distinguished between social contact and meaningful connection; (2) Contextual Causes: loneliness emerged from life transitions, stigmatized identities, and resource reduction (eg, youth services closures and social support); (3) Expressions and Language: clients rarely expressed loneliness directly, instead using proxy terms, with disclosure patterns varying by age; and (4) Mental Health Co-occurrence: severe mental health conditions created bidirectional cycles of loneliness, exacerbated by symptoms of mental health difficulties. Practitioners reported that many clients experienced loneliness concerns, yet direct disclosure was absent across all participants’ experiences. Conclusions: Practitioners identified multiple stigmatizing experiences as contextual drivers of loneliness, particularly demonstrating how loneliness emerges not only from individual experiences but from broader patterns of social exclusion and marginalization. For therapeutic practice, these insights suggest that practitioners can use awareness of stigmatizing experiences as potential indicators when assessing loneliness risk. The presence of contextual patterns was consistent across practitioners’ experiences, providing a foundation for developing more targeted interventions to address both the emotional experience of loneliness and the underlying social drivers.

AI Reveals Hidden Brain Lesions in Multiple Sclerosis MRI

It has long been known that brain gray matter plays a key role in multiple sclerosis (MS) disease progression and cognitive impairment, but because magnetic resonance imaging (MRI) has only been able to detect lesions in white matter, neither clinicians nor researchers have had a way to detect or monitor gray matter (cortical) lesions. And while many new drugs developed in the past decade can slow disease progression significantly, they primarily work on reducing white matter lesions.

A University at Buffalo (UB)-led team now reports that it has found a way to use artificial intelligence to reveal these otherwise invisible cortical lesions by reviewing existing MRI scans. The researchers say the significance of finally being able to see what has been known as one of the most important indicators in MS disease progression cannot be overstated.

“Detecting previously invisible cortical lesions on conventional legacy MRI scans has major implications for MS research and clinical care,” commented Robert Zivadinov, MD, PhD, SUNY distinguished professor in the Department of Neurology and director of the Buffalo Neuroimaging Analysis Center (BNAC) in the Jacobs School of Medicine and Biomedical Sciences at UB. “The ability to see for the first time these previously hidden indicators of MS disease progression, including cognitive impairment and disability, is an important advance.”

Added Michael G. Dwyer, PhD, associate professor of neurology and biomedical informatics in the Jacobs School and a researcher with BNAC, “What this collaboration has been able to accomplish is a real success story for applying AI in the medical arena. We now have access to these incredibly useful data on MRI scans that were there but you couldn’t see them without using AI to pull them out. The computational methods are finally at the point where we can do this.”

Zivadinov is senior author, Dwyer first and corresponding author of the team’s published paper in Communications Medicine, titled “Quantifying cortical lesions in multiple sclerosis MRI datasets using multi-contrast post- processing and deep learning.”

“Multiple sclerosis (MS) affects both the inner, connectivity-oriented portions of the brain (white matter) and the outer layer of the brain (the cortex),” the authors explained. While the involvement of cortical lesions in MS has been known almost since the identification of MS in the late 19th century, they weren’t included on diagnostic criteria until the 21st century. And even when they were included, it was noted that their use would be greatly limited due to the current capabilities of clinical MRI.

“Historically, research and clinical care in MS have focused on white matter, where focal demyelinating lesions are a hallmark of the disease,” they continued. And although there are now many therapies that can almost completely halt the incidence of new white-matter lesions in individuals with MS, they haven’t had the same impact on clinical progression, the team continued.

Over more recent decades it’s been found that gray matter is affected from the earliest MS disease stages, and it’s become evident that gray matter pathology is more than secondary to white matter damage. “From a clinical perspective, cortical lesions are strongly associated with clinical disability and cognitive impairment,” the authors stated. “They may also have more prognostic value than white matter lesions for disability and disease course.”

There’s an urgent need for in vivo imaging methods that can show gray matter lesions, they stressed. Dwyer added, “We have all been very frustrated, knowing that these cortical lesions were there but not being able to see them. There’s a lot of ongoing damage that continues to happen in MS that you won’t see with conventional MRI, but that histopathologists have been clearly demonstrating for decades on postmortem tissue.”

For their newly reported study the team applied advanced image processing techniques, including artificial intelligence, to standard MRI scans from a large MS clinical trial. “Recently, several post-processing methods, including synthetic contrasts and artificial intelligence (AI)-based approaches, have shown potential for enhancing cortical lesion detection on conventional MRI data,” they noted. “These methods have the potential to reanalyze existing clinical-trial data to answer key mechanistic questions about both MS development and about treatment effects.”

The AI approaches the researchers used, building on work from co-authors from the Netherlands, were designed to extrapolate vital information from the relationships between multiple images that can’t be seen on a single image.

The researchers combined multiple image-processing techniques, including a new one they developed called MMCLE, or multimodal cortical lesion enhancement. They then applied these techniques to MRI scans from the large, phase III FDA regulatory ORATORIO clinical trial, a study of the MS drug Ocrelizumab that included more than 700 participants.

They found that while individual images of a patient’s brain revealed mostly white matter lesions, once they applied the AI-based image processing methods to multiple different contrast images, they were able to see anywhere from 15 to 20 cortical lesions for each patient, more than 11,000 for the whole dataset. “We confirmed that cortical lesions can be clearly visualized and quantified with these methods,” they stated. “Using deep learning, we also confirmed that the simultaneous use of multiple contrasts improves quantification.”

Dwyer explained further, “If you look on the original scans, you generally can’t see the cortical lesions, but generative AI is very powerful because it can look between the scans and detect tiny differences between them. Because it sees those minor discrepancies, AI can reveal that there’s something going wrong there, that the tissue is not behaving like healthy tissue. The trained models can view multiple MRI images together and synthesize them and synthesize what had been missing.”

Zivadinov added “This work, which has revealed that there is so much invisible pathology in the brain, will have tremendous impact for reviewing data from past clinical trials and also for those going forward,” he says.
