PURPOSE To present full ophthalmologic examination and retinal nerve fiber layer (RNFL) photographs of autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) patients showing significant increases in RNFL thickness compared to healthy subjects, but without myelinated retinal fibers. METHODS The study design was observational case series. Ten eyes of five patients with molecular co...

BACKGROUND Behr's syndrome is a classical phenotypic description of childhood-onset optic atrophy combined with various neurological symptoms, including ophthalmoparesis, nystagmus, spastic paraparesis, ataxia, peripheral neuropathy and learning difficulties. OBJECTIVE Here we describe 4 patients with the classical Behr's syndrome phenotype from 3 unrelated families who carry homozygous nonse...

The autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS), presenting with spinocerebellar ataxia, dysarthria, nystagmus, and paraparesis, is a gradually progressive hereditary disease. Sensorimotor polyneuropathy may also accompany the symptoms. Herein, we present electrophysiologic findings Turkish family ARSACS in combination clinical genetic features to better describe characte...

Ataxia-telangiectasia syndrome is an autosomal recessive associated with combined immunodeficiency, progressive cerebellum ataxia, telangiectasia, ocolomotor apraxia, dysartheria and respiratory infections. In this study we reported three cases from a family with classical symptoms. Second sibling was died at 13 old years because severe respiratory infection but third and forth siblings have ...

Objective: This study aims to determine genotype-phenotype characteristics that can help diagnose hereditary ataxia, a rare disease. Methods: The findings of clinical, laboratory, electrophysiological, and magnetic resonance imaging thirteen patients with ataxia in the last five years were reported this study. Phenotypic expressions genetically proved mutation also reviewed. Results: We report ...

Reach guidance when the spatial location of the viewed target and hand movement are incongruent (i.e., decoupled) necessitates use of explicit cognitive rules (strategic control) or implicit recalibration of gaze and limb position (sensorimotor recalibration). In a patient with optic ataxia (OA) and bilateral superior parietal lobule damage, we recently demonstrated an increased reliance on str...
