99mTc-TRODAT-1 SPECT Imaging in Early and Late Onset Parkinson’s Disease
Objective(s): 99mTc-TRODAT-1, which binds to the dopamine transporter, could be used to image the dopaminergic system in diagnosis of Parkinson’s disease (PD). PD can be classified into two groups: late onset Parkinson’s disease (LOPD) and early onset Parkinson’s disease (EOPD). In this study we tried to determine the TRODAT SPECT findings in EOPD as compared to LOPD.Methods: Fifteen patients w...
متن کاملNeurochemical characteristics of early and late onset types of Alzheimer's disease.
Brains of 49 patients who had died with Alzheimer's disease and 54 controls were examined. The Alzheimer group exhibited noticeably reduced activity of the cholinergic marker enzyme choline acetyltransferase in the cerebral cortex, but cortical concentrations of noradrenaline, gamma-aminobutyric acid, and somatostatin were also significantly reduced. Analysis of the results according to age at ...
متن کاملFamilial aggregation of Parkinson disease: a comparative study of early-onset and late-onset disease.
CONTEXT It is unclear whether late-onset Parkinson disease (PD), which is the most typical and most common form of the disease, has a familial component. Evidence for familial aggregation is key to whether research should focus on gene discovery or search for environmental factors. OBJECTIVE To investigate familial aggregation of early-onset and late-onset PD separately. METHODS Using survi...

متن کاملSORL1 mutations in early- and late-onset Alzheimer disease
OBJECTIVE To characterize the clinical and molecular effect of mutations in the sortilin-related receptor (SORL1) gene. METHODS We performed whole-exome sequencing in early-onset Alzheimer disease (EOAD) and late-onset Alzheimer disease (LOAD) families followed by functional studies of select variants. The phenotypic consequences associated with SORL1 mutations were characterized based on cli...
