Psychiatric disorders frequently disrupt sleep, causing insomnia and poor sleep quality. Polysomnography reveals reduced sleep efficiency and altered sleep stages, particularly in depression.

Area of Science:

  • Neuroscience and Psychiatry
  • Sleep Medicine

Context:

  • Sleep disturbances are a hallmark symptom across numerous psychiatric disorders.
  • Clinical practice frequently encounters patients with sleep dysfunction linked to mental health conditions.

Purpose:

  • To review psychiatric disorders commonly associated with sleep dysfunction.
  • To describe characteristic polysomnographic findings in these conditions.

Summary:

  • Common patient complaints include difficulty initiating/maintaining sleep and poor sleep quality.
  • Early awakening is noted in depressive conditions; hypersomnia can occur in seasonal, atypical depression, and bipolar disorder.
  • Polysomnography generally shows reduced sleep efficiency, total sleep time, and slow-wave sleep, with shortened Rapid Eye Movement (REM) sleep latency often seen in depression and other disorders.

Impact:
