Application of insomnia treatment methods to reduce risk of major depressive disorder in older adults

Takeaway

  • Cognitive behavioral therapy for insomnia (CBT-I) may prevent incident and recurrent major depressive disorder (MDD) in older adults with insomnia disorder.

Why this matters

  • Depression is a significant risk factor for the development of other disorders, and insomnia, which occurs frequently in the elderly population, contributes to a greater risk of MDD.

  • CBT-I has proven effective in the treatment of insomnia, but its effects on prevention of MDD have not been well studied. This study supports efforts to target and treat insomnia disorder in older adults to maximize depression prevention in this population.
