Abstract

Spinocerebellar ataxia (SCA) is a hereditary disease characterized by central nervous system-related motor dysfunctions. Sleep disorders and frequent non-motor manifestations are commonly comorbid with SCA. To elucidate this relationship, we present three cases in a family that included multiple SCA type 2 patients with various sleep disorders. Complete physical examination, and genetic and imaging studies were performed. Anti-parkinsonism medications were prescribed after neurological examination. Clonazepam and/or quetiapine were administered for sleep disorders but failed to resolve insomnia and excessive daytime sleepiness (EDS). Based on DSM-5 criteria, all cases were diagnosed with depression. After treatment with serotonin-norepinephrine reuptake inhibitors and noradrenergic and specific serotonergic antidepressants, symptoms of insomnia and EDS, which are strongly associated with depression in SCA type 2 patients, improved significantly. It is crucial to recognize insomnia and EDS in neurodegenerative diseases, not only for earlier diagnosis, but also to improve quality of life.
