In this report we describe the outcome of a consensus meeting that occurred at the National Institutes of Health in Bethesda, Maryland, March 12 through 14, 2005. The meeting brought together 39 specialists from multiple clinical and research disciplines including developmental pediatrics, neurology, neurosurgery, orthopedic surgery, physical therapy, occupational therapy, physical medicine and...

OBJECTIVE Ocular motility abnormalities may be a marker of neuro-degeneration beyond motor neurons in amyotrophic lateral sclerosis (ALS). We formally compared clinical neuro-ophthalmic abnormalities in ALS patients and a control population. METHODS Patients attending a multidisciplinary ALS clinic (n=63, age 60.8+/-16.4 years) and their caregivers serving as controls (n=37, ages 55.0+/-12.7 ...

Background: Ataxia with oculomotor apraxia type 1 (AOA1) shows early onset with autosomal recessive inheritance and is caused by a mutation in the aprataxin (APTX) gene encoding for the APTX protein. Methods: In this study, a 7-year-old girl born of a first-cousin consanguineous marriage was described with early-onset progressive ataxia and AOA, with increased cholesterol concentration and decr...

Hereditary ataxias are a clinically and genetically heterogeneous family of disorders defined by the inability to control gait and muscle coordination. Given the nonspecific symptoms of many hereditary ataxias, precise diagnosis relies on molecular genetic testing. To this end, we conducted whole-exome sequencing (WES) on a large consanguineous Iranian family with hereditary ataxia and oculomot...

Corticobasal syndrome (CBS) is the clinical presentation of corticobasal degeneration (CBD), a rare neurodegenerative disorder, with features of both cerebral and basal ganglia involvement. Visual disturbance is uncommonly a predominant symptom but when present can be markedly debilitating. Visual findings primarily manifest as oculomotor apraxia, but significant cognitive impairment may result...

BACKGROUND Corticobasal syndrome (CBS) is characterized by multifaceted motor system dysfunction and cognitive disturbance; distinctive clinical features include limb apraxia and visuospatial dysfunction. Transcranial magnetic stimulation (TMS) has been used to study motor system dysfunction in CBS, but the relationship of TMS parameters to clinical features has not been studied. The present st...

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 ...

We describe the clinical and radiological findings of a pair of siblings with cerebellar vermis hypoplasia and compare them with the literature. Both of them present pregnancies and deliveries uneventful and both presented some grade of hypotonia, ataxia, ocular motor abnormalities and mild motor delay and slurred speech. These siblings meet many of the criteria described in non-progressive con...
