Clinical and Electronystagmographic findings in Friedreich's Ataxia

Dysarthria in Friedreichs Ataxia: A Perceptual Analysis

The aims of this study were to: (1) evaluate the perceptual speech dimensions, speech intelligibility and dys arthria severity of a group of individuals diagnosed with Friedreich’s ataxia (FRDA); (2) determine the presence of subgroups within FRDA dysarthria; (3) investigate the relationship between the speech outcome and the clinical factors of disease progression. The study included 38 indivi...

Electronystagmographic findings in patients with "whiplash" injuries.

Clinical laboratory findings in Friedreich's ataxia.

All clinical laboratory tests carried out in 4 groups of patients with the diagnosis of typical or atypical Friedreich's ataxia have been found to be within the normal range. In this prospective study of 50 patients, a number of findings previously reported to be abnormal in the literature, have not been confirmed.

Cardiomyopathy in Friedreich ataxia: clinical findings and research.

Friedreich ataxia is the most common human ataxia and results from inadequate production of the frataxin protein, most often the result of a triplet expansion in the nuclear FXN gene. The gene cannot be transcribed to generate the messenger ribonucleic acid for frataxin. Frataxin is an iron-binding protein targeted to the mitochondrial matrix. In its absence, multiple iron-sulfur-dependent prot...

Friedreich's ataxia. A clinical review with neurophysiological and echocardiographic findings.

In a review of twelve cases of Friedreich's ataxia, the important criteria for early diagnosis were identified. Clinical signs included absent tendon reflexes, ataxic gait, and a positive Romberg test. Nerve conduction velocities showed absent or severely slowed sensory conduction, with normal motor conduction. In addition, echocardiographic changes of symmetrical hypertrophic cardiomyopathy we...
