Online therapy developed in Montreal helps seniors sleep better, study finds

Half of the participants saw clinically significant reductions in insomnia symptoms, or a reduction of at least seven points on the Insomnia Severity Index, a commonly used questionnaire that measures the severity of sleep problems on a scale of 0 to 28, with higher scores indicating more severe insomnia.

Dr. Thien Thanh Dang-Vu, a neurologist specializing in sleep medicine and clinical researcher at the institute of geriatrics, said treating insomnia is important because poor sleep has been linked to a higher risk of depression, anxiety, heart disease, diabetes, and cognitive decline in older adults.

He added that seniors with insomnia often report low energy and difficulty concentrating, which can lead to a more sedentary lifestyle and social isolation. As a result, sleep plays an important role in maintaining quality of life and independence among older adults.

Dang-Vu said the online platform is not intended to replace doctors or psychologists. Instead, it aims to make evidence-based treatment available to more people, he added.

The two-month-long program is based on cognitive behavioural therapy, or CBT, widely considered the first-line treatment for chronic insomnia. According to Health Canada, CBT is a form of psychotherapy that helps people identify and change thoughts and behaviours.

Like traditional CBT, the online version developed by researchers at the institute combines education about sleep with practical strategies aimed at changing behaviours that can worsen sleep problems. One of those strategies may seem surprising: recommending that participants spend less time in bed.

“That’s what works best,” said Dang-Vu.

People with insomnia often remain in bed for long periods unable to sleep, which can reinforce frustration and make the problem worse, he explained. “This contributes to perpetuating insomnia,” Dang-Vu said.

The program uses questionnaires to tailor recommendations to each participant, including suggested sleep schedules. Unlike in-person therapy, participants can complete the program at their own pace.

“We’ve received fairly positive feedback from participants about this,” said Mathilde Reyt, the study’s lead author. Participants appreciated being able to work through the material on their own schedule and revisit information when needed, she said.

The team is now studying whether the program could also improve memory and cognitive function in older adults.

Researchers hope to eventually make the platform widely available, though that will depend on securing future funding.

“If we receive support … we will be very happy to make it available free of charge to all seniors in Quebec or Canada,” said Dang-Vu.
