Sleep Spindles in Torsion Dystonia

Sex related differences in nonmotor symptoms of patients with idiopathic blepharospasm

“…In an early polysomnographic study of ten patients with BSP and oromandibular dystonia, abnormal movement progressively decreased but did not disappear during sleep, and impaired sleep efficiency and decreased REM sleep were reported to correlate with the severity of dystonia especially in patients with lower craniocervical muscles involved 25 . However, no changes in sleep architecture and organization were found in another study on focal and generalized dystonia 26 . Our regression analysis showed that motor severity was not associated with sleep quality, which was consistent with a previous study on BSP 23 .…”

Nonmotor manifestations of dystonia: A systematic review

“…In a study of 10 patients with blepharospasm and oromandibular dystonia, impaired sleep efficiency and decreased REM sleep were found, both of which correlated with the severity of dystonia and EMG abnormalities 59. In contrast, a larger study of 24 patients with focal or generalized torsion dystonia (14 primary, 10 secondary) showed that sleep architecture and organization did not vary significantly from control patients 62…”

Neuropsychological and Neuropsychiatric Features of Idiopathic and DYT1 Dystonia and the Impact of Medical and Surgical treatment

“…They reported occasional occurrence of involuntary movements observed during wakefulness during stage one sleep or after awakening or lightening of sleep but not in the deeper stages of sleep (Fish et al, 1991a). They did not find any evidence of abnormal sleep spindles in primary torsion dystonia (Fish et al, 1990) and axial atonia was maintained during REM sleep in dystonia (Fish et al, 1991b). By contrast, an earlier study also using polysomnography reported abnormalities including overabundance of stage 2 sleep, a characteristic pattern or spindle activity, increased latency to sleep and reduced sleep efficiency in 25 cases from the literature and 4 cases examined by the investigators (Jankel et al, 1983).…”
