Parasomnia overlap disorder

Clinic

• POD consist of abnormal sleep-related behavior both in nonREM and REM sleep.

• They are typically manifesting as motor movements
• Conditions that provoke repeated cortical arousals, and/or promote sleep inertia, lead to NREM parasomnias by impairing normal arousal mechanisms.
• Changes in the cyclic alternating pattern, a biomarker of arousal instability in NREM sleep, are noted in sleepwalking disorders.
• Status dissociatus is referred to as a breakdown of the sleep architecture where an admixture of various sleep state markers is seen without any specific demarcation.
