Nightmares are a significant but treatable health condition that impact psychological health. Nightmares are commonly reported following trauma and often remain following successful treatment of PTSD. In 2018, the American Academy of Sleep Medicine position paper for the treatment of nightmare disorder in adults recommended to varying degrees various cognitive behavioral treatments for nightmares. Recently, nightmares experts have convened to develop a consensus approach and new treatment manual called Cognitive Behavioral Therapy for Nightmares (CBT-N). This institute will provide foundational understanding of normal sleep, assessment of sleep disorders, and guidance on how to implement CBT-N in clinical practice. We will achieve these goals by providing in-depth training based on the CBT-N manual, presenting case examples, providing handouts, and incorporating video demonstrations as well as audience exercises to reinforce learning.
