BACKGROUND AND PURPOSE Site-specific degeneration patterns of the infratentorial brain in relation to phylogenetic origins may relate to symptoms in patients with spinocerebellar degeneration, but the patterns are still unclear. We investigated macro- and microstructural changes of the infratentorial brain based on phylogenetic origins and their correlation with symptoms in patients with spinoc...
BACKGROUND Deep brain stimulation (DBS) has been utilized to treat various symptoms in patients suffering from movement disorders such as Parkinson's disease, dystonia, and essential tremor. Though ataxia syndromes have not been formally or frequently addressed with DBS, there are patients with ataxia and associated medication refractory tremor or dystonia who may potentially benefit from thera...
Purpose: To disclose the association between spinocerebellar ataxia with oculomotor apraxia and high grade (7 diopters) congenital astigmatism. Methods: Single observational case report. A 39-year-old patient affected by spinocerebellar ataxia from the age of 20 was submitted to genetic and ophthalmic investigations to reach a diagnosis. Results: Genetic testing did not lead to a sure diagnosis...
BACKGROUND The natural history of clinical symptoms in the spinocerebellar ataxias (SCA)s has been well characterised. However there is little longitudinal data comparing cognitive changes in the most common SCA subtypes over time. The present study provides a preliminary longitudinal characterisation of the clinical and cognitive profiles in patients with SCA1, SCA2, SCA3, SCA6 and SCA7, with ...
CACNA1A mutations cause a range of disorders with diverse, sometimes overlapping clinical features. Point mutations, including missense mutations, nonsense mutations, splicing mutations and small deletions/insertions, result in a variety of phenotypes including episodic ataxia type 2 (EA2) and familial hemiplegic migraine type 1 (FHM1). These 2 conditions show clinical overlap with spinocerebel...
Autosomal dominant cerebellar ataxia corresponds to a clinically and genetically heterogeneous group of neurodegenerative disorders that primarily affect the cerebellum. Here, we report the identification of the causative gene in spinocerebellar ataxia 21, an autosomal-dominant disorder previously mapped to chromosome 7p21.3-p15.1. This ataxia was firstly characterized in a large French family ...
BACKGROUND The inositol 1,4,5-triphosphate (IP3) receptor type 1 gene (ITPR1) encodes the IP3 receptor type 1 (IP3R1), which modulates intracellular calcium homeostasis and signaling. Mutations in ITPR1 have been implicated in inherited cerebellar ataxias. The aim of this study was to investigate the role of ITPR1 mutations, including both large segmental deletion and single nucleotide mutation...
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear etiology. Recently, intermediate CAG repeat expansions in ATXN2, the gene responsible for spinocerebellar ataxia type 2 (SCA2), have been identified as a possible genetic risk factor for ALS. In this study, we analyzed the ATXN2 CAG repeat length in Chinese patients with ALS to evaluate the relationship betwe...
