Merola A, Dwivedi AK, Shaikh AG, Tareen TK, da Prat GA, Kauffman MA, et al. Head tremor at onset heralds a CD subtype with prominent axial cerebellar disability and atrophy of the superior vermis of the cerebellum. Tr-CD patients exhibited greater superior vermian atrophy than nTr-CD patients ( p = 0.01). SARA scores inversely correlated with cerebellar volume in all patients (− 0.4, p = 0.04).
Compared to nTr-CD ( n = 10, median age, 70.5 years), Tr-CD patients ( n = 10, 71.5 years) exhibited higher median SARA scores (9 vs 7.5, p = 0.03) and greater median gait variability index (131 vs 124, p = 0.03). All patients were evaluated for cerebellar disability using the Scale for the Assessment and Rating of Ataxia (SARA), gait variability using ProtoKinetics Zeno Walkway, and cerebellar volume analysis extracted from brain magnetic resonance imaging (MRI) using a semiquantitative scale. CD patients with head tremor at onset (Tr-CD) were age- and sex-matched to CD patients without head tremor at onset (nTr-CD). The objective of this study is to examine the role of the cerebellum in the tremor-dominant subtype of cervical dystonia (CD).
