Parkinson's Disease

Parkinson`s-related insomnia

08/09/2006

Question:

What causes insomnia in Parkinson patients?

Answer:

Sleep disturbances are very common in persons with Parkinson's disease (PD).  Insomnia is the most common, usually manifested by fragmented sleep (frequent awakenings).  This may be due to immobility during the night and thus discomfort in bed.  Other causes include depression, anxiety, Restless Legs Syndrome, REM behavioral disorder (acting out dreams) or nocturia (frequent urination at night).  PD is a disease of abnormal levels of brain chemicals due to degenerative brain cells and so this will directly affect sleep patterns also.  In fact, it may be one of the early features of the disease.
