Substance/Medication-Induced Sleep Disorder
Risk factors
Temperamental
Substance use generally precipitates or accompanies insomnia in vulnerable individuals. Thus, presence of insomnia in response to stress or change in sleep environment or timing can represent a risk for developing substance/medication-induced sleep disorder.
A similar risk may be present for individuals with other sleep disorders (e.g., individuals with hypersomnia who use stimulants).
Symptoms
A prominent and severe disturbance in sleep.
There is evidence from the history, physical examination, or laboratory findings.
The symptoms developed during/soon after substance intoxication or after withdrawal from or exposure to a medication.
The involved substance/medication is capable of producing the symptoms.
The disturbance is not better explained by a sleep disorder that is not substance/ medication-induced.
The disturbance does not occur exclusively during the course of a delirium.
The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.
