OBJECTIVE To evaluate the association between cerebrospinal fluid (CSF) homovanillic acid (HVA) concentrations and nigrostriatal dopaminergic function assessed by positron emission tomography (PET) imaging with carbon-11-labeled 2beta-carbomethoxy-3beta-(4-fluorophenyl)-tropane ((11)C-CFT), which can measure the dopamine transporter (DAT) density, in Parkinson's disease (PD). METHODS (11)C-CFT PET scans and CSF examinations were performed on 21 patients with PD, and six patients with non-parkinsonian syndromes (NPS) as a control group. RESULTS In the PD group, CSF HVA concentrations were significantly correlated with the striatal uptake of (11)C-CFT (r = 0.76, P < 0.01). However, in the NPS group, two indices were within the normal range. CONCLUSIONS In PD, CSF HVA concentrations correlate with nigrostriatal dopaminergic function. Therefore, CSF HVA concentrations may be an additional surrogate marker for estimating the remaining nigrostriatal dopaminergic function in case that DAT imaging is unavailable.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010300 Parkinson Disease A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

D004298 Dopamine One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
