Introduction:
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.
