Sleep, PTSD and Alcoholism

Sleep disturbances associated with posttraumatic stress disorder and alcohol dependence

Sleep disturbances commonly appear in the context of both posttraumatic stress disorder (PTSD) and alcohol use disorders.

Sleep symptoms typically reported among clinical populations include;

delayed sleep onset,
poor sleep continuity,
early morning awakening, and
disturbed sleep architecture.

The aim of the present study was to examine multiple forms of sleep disturbances among individuals with comorbid PTSD and alcohol dependence, PTSD only, alcohol dependence only, and a control group.

Both PTSD and alcohol dependence diagnoses were associated with multiple forms of sleep disturbance, but comorbidity of the two disorders did not appear to increase the risk over and above either single disorder for reporting any of the sleep difficulties examined.

As PTSD symptom severity increased, so did

sleep latency,
mid-sleep wakening, and
early morning wakening.

However, contrary to our hypothesis, no significant direct relationship between severity of alcohol use and sleep disturbances was revealed.

These findings suggest a need for thorough assessment of sleep symptoms in patients presenting with PTSD or alcohol dependence.
