Mutation Analysis of HTRA2 Gene in Chinese Familial Essential Tremor and Familial Parkinson's Disease
Background. HTRA2 has already been nominated as PARK13 which may cause Parkinson's disease, though there are still discrepancies among these results. Recently, Gulsuner et al.'s study found that HTRA2 p.G399S is responsible for hereditary essential tremor and homozygotes of this allele develop Parkinson's disease by examining a six-generation family segregating essential tremor and essential tr...
متن کاملClinical correlates of action tremor in Parkinson disease.
BACKGROUND Action tremor is often noted in patients with Parkinson disease (PD), yet the clinical correlates of this type of tremor have been the focus of few studies. It is not clear whether this action tremor is a manifestation of the underlying basal ganglia disease. OBJECTIVE To determine whether the severity of action tremor in PD is associated with age, age at disease onset, disease dur...
متن کاملTremor-correlated cortical activity in essential tremor.
BACKGROUND In patients with parkinsonian resting tremor, tremor-correlated activity in the contralateral sensorimotor cortex has been studied by both magnetoencephalography (MEG) and electroencephalography (EEG). In essential tremor, MEG failed to detect cortical involvement. The objective of this study was to investigate whether EEG recording can reveal tremor-correlated cortical activity in p...
متن کاملImprovement of Primary Writing Tremor in Parkinson’s Disease with Carbidopa/Levodopa
BACKGROUND Primary writing tremor is a task-specific phenomenon that has been described as variants of essential tremor or dystonia. PHENOMENOLOGY SHOWN We describe the case of a 63-year-old female who initially had primary writing tremor, later developed Parkinson's disease, and once initiated on carbidopa/levodopa had improvement in her parkinsonism and her writing tremor. EDUCATIONAL VAL...
متن کاملH1-MAPT and the Risk for Familial Essential Tremor
The most frequent MAPT H1 haplotype is associated with the risk for developing progressive supranuclear palsy and other neurodegenerative diseases such as Parkinson's disease. A recent report suggests that the MAPT H1 is associated with the risk for developing essential tremor. We wanted to confirm this association in a different population. We analyzed the distribution of allelic and genotype ...
