Impact of Insomnia Treatment on Brain Responses During Resting-state and Cognitive Tasks

"Participants with chronic primary insomnia are randomized into 2 groups with a 1:1 allocation ratio, after the completion of the pre-treatment assessment. Post-treatment and post-waitlist assessment occur after the 3-month treatment or waiting period.~One group will receive the intervention immediately after the pre-treatment assessment and the other group will receive the intervention after a waiting period of 3 months. The intervention consists of manualized cognitive-behavioural therapy for insomnia. This treatment includes psychoeducation about sleep and circadian rhythms, stimulus control, sleep restriction, relaxation, and cognitive therapy. The therapy is administered individually. Participants meet for 8 sessions of 50 minutes spread over 12 weeks."
