Incidental Lewy body disease and preclinical Parkinson disease.
BACKGROUND The significance of Lewy bodies detected at autopsy in the brains of clinically normal individuals is uncertain but may represent preclinical Parkinson disease (PD). OBJECTIVE To determine whether diminished striatal dopaminergic innervation and nigral cell loss are present in incidental Lewy body disease (iLBD), as one might expect if it is a forerunner of PD. DESIGN Case-contro...
متن کاملStriatal monoamine terminals in Lewy body dementia and Alzheimer's disease.
We used positron emission tomography (PET) with (+)-[(11)C]dihydrotetrabenazine ([+]-[(11)C]DTBZ) to examine striatal monoaminergic presynaptic terminal density in 20 patients with dementia with Lewy bodies (DLB), 25 with Alzheimer's disease (AD), and 19 normal elderly controls. Six DLB patients developed parkinsonism at least 1 year before dementia (DLB/PD) and 14 developed dementia before par...
متن کاملAre striatal tyrosine hydroxylase interneurons dopaminergic?
Striatal GABAergic interneurons that express the gene for tyrosine hydroxylase (TH) have been identified previously by several methods. Although generally assumed to be dopaminergic, possibly serving as a compensatory source of dopamine (DA) in Parkinson's disease, this assumption has never been tested directly. In TH-Cre mice whose nigrostriatal pathway had been eliminated unilaterally with 6-...
متن کاملAlterations in peptide levels in Parkinson's disease and incidental Lewy body disease.
The levels of the neuropeptides Met- and Leu-enkephalin (MET-ENK, LEU-ENK), substance P and neurotensin were measured by a combined high performance liquid chromatography/radioimmunoassay (HPLC/RIA) method in postmortem samples of basal ganglia from Parkinson's disease patients, incidental Lewy body disease patients (pre-symptomatic Parkinson's disease) and matched controls. Dopamine (DA) level...
متن کاملCortical Lewy body disease.
C ortical Lewy body disease is a pathological observation rather than a distinct clinicopathological entity. Cortical Lewy bodies (CLB) are typically found in Parkinson’s disease and dementia with Lewy bodies (DLB), although they may also occur in other neurological disorders. Unlike their brain stem counterparts, CLB are less distinctive and are poorly visualised using conventional histochemic...
