Preliminary data suggest potential benefit of 5-HT receptor agonists in the treatment of ataxias. We studied the effects of buspirone in a cohort of twenty patients with spinocerebellar ataxia (SCA). Twenty patients were treated in this double-blind, placebo controlled, cross-over trial with either buspirone HCl 30 mg twice daily or placebo for 3 months. Buspirone was not shown to be superior to placebo in the treatment of patients with SCA.

The expansion of glutamine residue track (polyQ) within soluble proteins (Q proteins) is responsible for nine autosomal-dominant genetic neurodegenerative disorders. These disorders develop when polyQ expansion exceeds a specific pathogenic threshold (Q) which is unique for each disease. However, the pathogenic mechanisms associated with the variability of Q within the family of Q proteins are poorly understood.

Background: The regulatory role of the apolipoprotein E (APOE) ε4 allele in the clinical manifestations of spinocerebellar ataxia type 3 (SCA3) remains unclear. This study aimed to evaluate the impact of the APOE ε4 allele on cognitive and motor functions in SCA3 patients.
Methods: This study included 281 unrelated SCA3 patients and 182 controls.

Spinocerebellar ataxias (SCAs) are a diverse and heterogeneous group of inherited neurodegenerative disorders marked by progressive ataxia and cerebellar degeneration. This case report details an 11-year-old Indian boy with childhood-onset ataxia and severe sensorineural hearing loss, a rarely reported concomitance in pediatric neurology. Genetic analysis identified a unique heterozygous 3' splice site variant in the PNPT1 gene (c.

The cerebellum is a highly conserved brain compartment of vertebrates. Genetic diseases of the human cerebellum often lead to degeneration of the principal neuron, the Purkinje cell, resulting in locomotive deficits and socio-emotional impairments. Due to its relatively simple but highly conserved neuroanatomy and circuitry, these human diseases can be modeled well in vertebrates amenable for genetic manipulation.
