First report of spastic ataxia of Charlevoix-Saguenay cases in Mexico. Novel SACS gene mutations identified

Neurology Perspectives, 2022
Introduction and objectives: Spinocerebellar ataxia autosomal recessive (SCAR) represents a heterogeneous chronic and progressive neurological diseases group. They usually occur at an early age in a progressive manner.

Breathe, Eat, Talk: Three Essential Ingredients to Quality-of-Life Outcomes in Movement Disorders. [PDF]

Mov Disord Clin Pract
Abstract Background Breathing, eating, and talking (BET) impairments are common yet frequently underrecognized features of movement disorders. Deficits in respiration, swallowing, voice, and speech may emerge early in the course of a disease, adversely affecting safety, participation, and quality of life.

Genetics of Friedreich Ataxia

Pediatric Neurology Briefs, 1997
Genotype-phenotype correlations in a group of 100 patients with typical Friedreich ataxia (FRDA), and in three smaller clinically atypical groups (Arcadian FRDA, late-onset FRDA (LOFA), and FRDA with retained reflexes (FARR)), were studied at the Centre ...

Keys to overcoming the challenge of diagnosing autosomal recessive spinocerebellar ataxia

Neurología (English Edition), 2019
Introduction: Autosomal recessive spinocerebellar ataxia refers to a large group of diseases affecting the cerebellum and/or its connections, although they may also involve other regions of the nervous system.

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Juvenile Huntington Disease With Cerebellar‐Predominant Atrophy Identified by Genome Sequencing

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Juvenile Huntington disease accounts for a small fraction of Huntington disease cases and is driven by the largest trinucleotide repeat expansions. We describe a 6‐year‐old boy with progressive global regression, generalized dystonia, and epilepsy, in whom serial imaging showed striking cerebellar‐predominant atrophy with an initially normal ...

Establishing Sensory Neurons as Therapeutic Targets in Peripheral Neuropathy Driven by Polyglutamine Expanded Murine ATXN3

Annals of Neurology, EarlyView.
Repeat expansion disorders frequently involve peripheral neuropathy, yet mechanisms remain unclear. Using a spinocerebellar ataxia type 3 (SCA3) Knock‐In Atxn3Q300/Q6, we identify progressive sensorimotor deficits, peripheral nerve pathology, and dorsal root ganglia RNA splicing dysregulation.
