[Sleep disorders in Parkinson's disease and other movement disorders]

Neurodegenerative processes with movement disorders is predominant features show a high incidence of sleep alterations at some point in their evolution. The degeneration of structures responsible for maintaining the sleep-wakefulness cycles and the architecture of sleep could be at their root. Other factors like the drugs employed in the treatment of motor problems, the limitations to movement, etc., aggravate the problem. Although, at present, there is no medical therapy able to restore the defects derived from the degeneration of the key structures of sleep, an individual analysis of the coadyuvant factors in each patient could help to improve these problems. In this article we describe the main sleep disorders in Parkinson's disease and other degenerative diseases such as multi-system atrophies or progressive supranuclear paralysis.
