In Montreal, researchers have cracked a puzzle that affects millions of older adults: how to treat insomnia and anxiety at the same time, without requiring a scarce (and expensive) appointment with a therapist. Their answer is eCBT+, a seven-week online program delivered through video modules that people can access on a computer, tablet, or smartphone whenever they need it.
The problem is real and urgent. Insomnia and anxiety are deeply common among adults 65 and older, yet cognitive behavioral therapy—the gold-standard treatment for insomnia—remains locked behind barriers of cost and availability. There simply aren't enough trained professionals to meet demand, and the people who need help most often can't afford it. That gap matters because when older adults struggle with sleep, it ripples outward: their mental health suffers, their days feel heavier, and their overall quality of life declines.
Researchers at the Centre de recherche de l'Institut universitaire de gériatrie de Montréal (CRIUGM), working alongside Concordia University, Université Laval, and the Université de Montréal, set out to change that. Dr. Thien Thanh Dang-Vu, a neurologist and laboratory director at CRIUGM, led a team that designed a digital platform specifically for older users—the first of its kind available in French. They built it with features like adjustable text size and contrast settings, and filled it with scenarios that reflected the actual lives of seniors, not generic wellness content.
The team tested their invention in a rigorous randomized controlled trial with 80 adults aged 65 and older who had insomnia. Participants engaged with the eCBT+ program over seven weeks, completing one 30-minute interactive video module each week. The results, published in the journal Age and Ageing, were striking. Participants who completed the program experienced significant improvements in sleep efficiency and meaningful reductions in both insomnia and anxiety symptoms compared to a control group that waited for treatment.
The numbers told an important story about usability too. Participants rated the platform as user-friendly and intuitive, achieving a usability score of nearly 70%—a validation that digital tools could actually work for older people, not just younger tech-savvy users. People said they embraced the program because it was easy to navigate and genuinely useful, not because they felt pressured into trying something trendy.
"From a clinical perspective, the intervention proved highly effective," says Mathilde Reyt, the study's first author and postdoctoral researcher at CRIUGM and Concordia University. The implication is profound: web-based tools aren't just convenient alternatives to in-person therapy—they appear to deliver real, measurable improvements in sleep and mental health for older adults.
The research team isn't stopping here. They plan to expand their sample size to understand the program's long-term effects, with particular interest in whether better sleep and lower anxiety translate to sharper thinking and brighter days for older adults. That work matters because it could reshape how healthcare systems approach mental health in aging populations, turning an accessibility problem into an opportunity for widespread, scalable care.
