olivopontocerebellar atrophies/tremor

We report on a 54-year-old woman with an 8 or so year history of olivopontocerebellar atrophy associated with the rhythmic involuntary movements of the left upper and lower limbs, and cervical region. Surface electromyogram of the left upper limb revealed rhythmicity (about 3 Hz) and reciprocity

Thirty-nine patients with a variety of diseases, including essential tremor, Parkinson's Disease, olivopontocerebellar degeneration, ataxia telangiectasia, and cervical cord injury with action tremor, were evaluated for the effect of one ounce of absolute alcohol ingestion. Tremor significantly

Olivary nucleus degeneration is one of the pathologic characteristics of infantile olivopontocerebellar atrophy. It has also been described in premature neonates and infants with severe perinatal asphyxia and is thought to represent retrograde transsynaptic changes from cerebellar hemisphere

OBJECTIVE To report bilateral high-frequency synchronous discharges in a patient with a sporadic form of olivopontocerebellar atrophy; to investigate the electromyographic pattern, the coherence and cospectral density across limbs, and the resetting effects of electrical stimulation over the

CONCLUSIONS Morphometry and spectroscopy were performed in 3 patients with fragile X-associated tremor/ataxia syndrome (FXTAS). The brain stem and cerebellum were atrophic and satisfied criteria for olivopontocerebellar atrophy in 2 patients. However, the vermis was relatively spared and the basis

Striatonigral degeneration (SND) and sporadic olivopontocerebellar atrophy (sOPCA) are categorized under multiple system atrophy (MSA), since these disorders have common clinical and pathological features. However, it is still uncertain whether these disorders are manifestation of the same disease.

Clinical diagnoses of Parkinson's disease (PD) is highly inaccurate. Olivopontocerebellar atrophy (OPCA) is a major source of diagnostic confusion. We have studied the clinical characteristics of 50 patients with PD, 24 patients with OPCA judged by the presence of selective atrophy of the cerebellum

Cases of young patients with different diseases of nervous system in which tremor was the main symptom, clinical peculiarities of trembling hyperkinesis in essential tremor, in olivopontocerebellar degeneration, in strionigral atrophia, in residual phenomena of organic brain damages as well as their

In this clinicopathological conference we discuss the case of a patient aged 49 years, who developed progressive clinical picture characterized by palatal tremor (PT), segmental myoclonus, cerebellar ataxia, parkinsonism, amyotrophy, pyramidal signs, supranuclear ophthalmoplegia, parkinsonism and

We describe a patient with an unusual clinical presentation of progressive multiple cranial nerve palsies, cerebellar ataxia, and palatal tremor (PT) resulting from an unknown etiology. Magnetic resonance imaging showed evidence of hypertrophy of the inferior olivary nuclei, brain stem atrophy, and

H. I., a housewife aged 55 years, began feeling a gait disturbance at 48 years old. After this she had incoordination of arms, dysarthria and tremor of hands. Aged 54 years, she could not stand up by herself. In addition to these neurological signs she had a change of character, such as losing

The olivopontocerebellar atrophies (OPCA) can be divided into five disease entities. One of these, dominant OPCA with dementia and extrapyramidal signs, is better defined by the family we studied. Five persons in three generations were affected by progressive ataxia, tremor, rigidity and mental

We reported a case of crossed cerebello-cerebral diaschisis (CCCD) in olivopontocerebellar atrophy (OPCA). A 49-year-old male was admitted with complaints of titubation, dysarthria and tremor. Examination on admission revealed exaggerated triceps, patella and achilles tendon reflexes on both sides

The combination of spinal muscular atrophy (SMA) with a variety of neural and extraneural defects, particularly pontocerebellar hypoplasia, has been reported. To date, all of the reported SMA with pontocerebellar hypoplasia was from infants; however, here we report a SMA with sporadic

The authors analyzed rhythmical involuntary movements at rest, which appeared as complications in 12 (sporadic 11, hereditary 1) out of a total of 139 cases (sporadic 99, hereditary 40) of olivo-ponto-cerebellar atrophy. These movements tended to be seen in patients with sporadic OPCA of longer
