Sleep and vigilance in corticobasal degeneration: a descriptive study.
BACKGROUND
Sleep disorders are common in extrapyramidal diseases, but have rarely been demonstrated in corticobasal degeneration (CBD).


METHODS
Here, we describe sleep and vigilance in five consecutive patients with CBD.


RESULTS
All five patients had insomnia, four displayed periodic limb movements during sleep (PLMS) and/or restless leg syndrome (RLS), and two had sleep respiratory disorders. None had REM sleep behaviour disorders or excessive daytime sleepiness.


CONCLUSIONS
Polysomnography is useful for diagnosing treatable sleep disorders in CBD.
