Accuracy of clinic diagnosis of idiopathic Parkinson’s disease: A positron emission tomography study of the short-term maintenance of verbal information. The Wechsler Adult Intelligence Scale. Introduction-objective To describe the history of the discovery of SCA36 and espinocerehelosa knowledge of this entity, which is currently the most prevalent hereditary ataxia in Galicia Spain owing to a founder effect.

Mitochondrial cytopathies, both those arising from mitochondrial DNA mutations maternal inheritance and those resulting from somatic mutations, 32 are associated with a wide range of symptoms including ataxia and hypoacusia and may therefore be mistaken for SCA Spinocerebellar ataxia 36 SCA Phenotypic spectrum associated with mutations of the mitochondrial polymerase gamma gene.

The possibility of a familial association between Costa da Morte ataxia and Asida River ataxia described in Japan and caused by a similar mutation has yet to be confirmed. On the clinical symptoms of cerebellar disease.

Harding’s classification remains very useful for the initial assessment of patients with ataxia and an autosomal dominant inheritance pattern.

As this region has a history of intense emigration, SCA36 may also have spread to numerous other areas. Accepted 5 June A MRI scans reveal cerebellar atrophy as early as symptom onset; it usually starts in the superior cerebellar vermis and extends to the rest of the cerebellum down to the brainstem, displaying a pattern of olivopontocerebellar atrophy Fig.

As genetic studies of the first types of SCA became available, we observed that our patients did not carry the mutations or genetic linkages described in the literature. Friedreich ataxia and such other autosomal recessive ataxias as ataxia with oculomotor apraxia types 1 and 2, ataxia-telangiectasia, and cerebrotendinous xanthomatosis may exceptionally show late onset with a mild phenotype resembling that of SCA36, although they show clinical and neurophysiological features of peripheral neuropathy 31 ; these entities should therefore be included in the differential diagnosis in certain cases.

The cerebellum and cognition. Atrlfia studies are now available to patients and asymptomatic carriers. SCA36 is an autosomal dominant hereditary ataxia with late onset and slow progression.

The Journal accepts works on basic as well applied research on any field of neurology. The first loci linked to specific ADCA types began to be identified after 7,8 and that acronym atrofiaa replaced by SCA spinocerebellar ataxia. The cerebellar group showed significant lower performance in measures of attention and EF, with a significant increase in both perseverative and non perseverative errors during the WCST.
