Spinocerebellar ataxia type 3 (SCA3) can be present with a combination of cerebellar, neuropathic, pyramidal, or extrapyramidal symptoms. Tremor is a classical but not frequent manifestation of SCA3 and there is a lack of detailed knowledge regarding its origin. To study the clinical and
Previous studies demonstrated cognitive impairments in spinocerebellar ataxia type 3 (SCA3/MJD); however, there is no consensus about the cognitive domains affected and the correlation with structural brain abnormalities. We investigated the neuropsychological profile and 3T-MRI findings, including
OBJECTIVE
To detect specific oculomotor deficits in preclinical stage of spinocerebellar ataxia type 3 (SCA3) and evaluate whether these abnormalities prove useful as potential biomarkers of disease progression.
METHODS
A Chinese cohort of 56 patients with SCA3, including 12 preclinical carriers of
Controversies about Mendelian segregation and CAG expansion (CAGexp) instabilities during meiosis in spinocerebellar ataxia type 3/Machado-Joseph disease (SCA3/MJD) need clarification. Additional evidence about these issues was obtained from the cohort of all SCA3/MJD individuals living in South
A genetically confirmed case of spinocerebellar ataxia type 3 (SCA 3), presenting with disabling foot dystonia, peripheral neuropathy, and minimal cerebellar signs is reported. The dystonia improved dramatically with levodopa treatment in the absence of additional parkinsonian feature. A trial of
Spinocerebellar Ataxia Type 3 (SCA3), also known as Machado-Joseph disease, is an autosomal dominantly inherited neurodegenerative disease caused by an expanded polyglutamine stretch in the ataxin-3 protein. A pathological hallmark of the disease is cerebellar and brainstem atrophy, which correlates
Clinical characteristics: Spinocerebellar ataxia type 3 (SCA3), also known as Machado-Joseph disease (MJD), is characterized by progressive cerebellar ataxia and variable findings including pyramidal signs, a dystonic-rigid extrapyramidal syndrome, significant
Tandospirone citrate (tandospirone) is an anti-anxiety drug that acts by combining with serotonin receptor (5-hydroxytryptamine-1 A [5-HT1A]). Recently, there have been a few reports of its potential role in the treatment of cerebellar ataxia. We report the first case of a patient with
Machado-Joseph disease (MJD) and Holguin ataxia (SCA2) are autosomal dominant multisystem degenerations with spinocerebellar involvement that are predominant among people of Portuguese-Azorean and of Cuban descent, respectively. Their clinical distinction may at times be difficult to make in
Background: Homozygous spinocerebellar ataxia type 3 (SCA3) patients, which have an expanded cytosine-adenine-guanine (CAG) repeat mutation in both alleles of ATXN3, are extremely rare. Clinical features and genetic characteristics of
Many of the spinocerebellar ataxias (SCAs) are caused by expansions of CAG trinucleotide repeats encoding abnormal stretches of polyglutamine. SCA3 or Machado-Joseph disease (MJD) is the commonest dominant inherited ataxia disease, with pathological phenotypes apparent with a CAG triplet repeat
A subgroup of trinucleotide repeat diseases result from abnormal expansions of CAG repeats which are translated into polyglutamine stretches. As yet there is little understanding of how the polyglutamines function either normally, or when expanded. We have investigated these sequences in the
Machado-Joseph disease (MJD) is a spinocerebellar ataxia, and osteoporosis is a multifactor disease that may affect patients with neurologic conditions. The frequency of osteoporosis among MJD patients, however, has not been studied. The purpose of this study is to evaluate bone OBJECTIVE
To evaluate the metabolite pattern and the severity in patients with spinocerebellar ataxia type 3/ Machado-Joseph disease (SCA3/MJD) by (1)H magnetic resonance spectroscopy ((1)H-MRS) on different cerebellar regions, including cerebellar vermis, cerebellar peduncles, cerebellar cortex,
Alongside with the emergent clinical trials for Machado-Joseph disease/Spinocerebellar ataxia type 3 (MJD/SCA3) comes the need to identify molecular biomarkers of disease that can be tracked throughout the trial. MJD is an autosomal dominant neurodegenerative disorder caused by expansion of a CAG
