Cerebellar ataxias comprise a wide range of etiologies leading to central nervous
system-related motor and non-motor symptoms. Recently, a large body of evidence
has demonstrated a high frequency of non-motor manifestations in cerebellar ataxias,
especially in autosomal dominant spinocerebellar ataxias (SCA). Among these nonmotor
dysfunctions, sleep disorders have been recognized, although still under or even
misdiagnosed. In this review, we highlight the main sleep disorders related to cerebellar
ataxias focusing on REM sleep behavior disorder (RBD), restless legs syndrome (RLS),
periodic limb movement in sleep (PLMS), excessive daytime sleepiness (EDS), insomnia
and sleep apnea.
