Excessive Daytime Sleepiness - Causes

Causes

EDS can be a symptom of a number of factors and disorders. Specialists in sleep medicine are trained to diagnose them. Some are:

• Insufficient quality or quantity of night time sleep.
• Misalignments of the body's circadian pacemaker with the environment (e.g. jet lag, shift work or other circadian rhythm sleep disorders).
• An underlying sleep disorder, such as narcolepsy, sleep apnea, hypersomnia or restless legs syndrome.
• Disorders such as clinical depression or atypical depression.
• Tumors, head trauma, anemia, kidney failure, hypothyroidism or an injury to the central nervous system.
• Drug abuse.
• Genetic predisposition.
• Particular classes of prescription and OTC medication
