In the early stages of degenerative cerebellar ataxias, cerebellar atrophy may be mild, making detection of ataxia challenging through clinical examinations. Several studies have investigated visuomotor adaptation abilities in patients with cerebellar disorders [16, 25, 26], but there has been limited ...
In cerebellar patients, this effect is referred to as dysmetria38 which in the motor domain results in ataxia. Ataxia is the lack of coordination and fine control during voluntary movements, a defining symptom resulting from cerebellar malfunction11,38. To evaluate the degree of dysmetria-like ...
The final differentiation of UBCs occurs between P2 and P28. Morin et al. [126] divided the maturation of type I UBCs into four distinct stages based on the morphological appearance of the dendritic brush (the protodendritic, filopodial, intermediate brush, and dendriolar brush stages). In ...
As a final assessment of motor function, gait analysis (Fig.4A) was performed to assess changes in the forelimb and hindlimb stride length and width (Fig.4). Except for hindlimb stride width, there were significant main effects of genotype and age on the remaining three parameters: forelimb s...
Interestingly, we found signifi- cant overlaps of DEGs identified in both vGluT2+ and Gad2+ cerebellar neurons with DEGs in the cerebellum of a knock-in mouse model of Spinocerebellar ataxia 1 (SCA1) [OMIM:164400], an autosomal dominant dis- ease caused by expansion of a ...
SCA28 is characterized by juvenile onset slowly progressive cerebellar ataxia due to Purkinje cell degeneration. Some persons show cognitive impairment [114]. And in more advanced stages of the syndrome, ophthalmoparesis, slowed saccades, ptosis and pyramidal signs were reported [115]. The mean ag...
[43]. Cerebellar injuries, stroke, and ataxia are associated with difficulties swallowing (dysphagia) and chewing [44,45,46,47,48], demonstrating the importance of an intact cerebellum in the physical ability to eat. This section will discuss the role of the cerebellum in both the voluntary (...
male plKO mice exhibited a mild alteration of their walking pattern, with higher percentage of long steps (Extended Data Fig.8a,b). The frequency of missteps, often increased in ataxia models, was unchanged (Extended Data Fig.8g). The locomotion speed was similar in male plKO and C on the...

Two different clinical subtypes have been described based on the pre- dominating motor features noted during the early stages of the disease: the MSA-P subtype (dominated by par- kinsonism) and the MSA-C subtype (dominated by cere- bellar ataxia). However, in the later stages of the ...
