TL;DR
It is suggested that dopamine neurons are linked both to normal aging and to HD and that CSF HVA studies can distinguish differences in the functioning of dopamine neurons innormal aging and HD.
Abstract
We measured four monoamine metabolite levels in CSF before and after probenecid administration to normal controls and to patients with Huntington's disease (HD), dystonia, and tardive dyskinesia. We identified differences only for the dopamine metabolite homovanillic acid (HVA), which showed increased baseline values and decreased turnover in normal aging, but decreased baseline values and normal turnover in HD. These results suggest that dopamine neurons are linked both to normal aging and to HD and that CSF HVA studies can distinguish differences in the functioning of dopamine neurons in normal aging and HD.

It is concluded that an explanation of the latter syndrome of persistent drug-related TD remains uncertain, and the phenomenon of DA-supersensitivity might help to explain some of the acute "withdrawal dyskinesias" that follow the abrupt discontinuation of high doses of antipsychotic agents, but may be too short-lived to explain the persistent forms of TD.

CSF metabolite and CSF probenecid concentrations were significantly correlated in depressed patients for all metabolites, and there was decreased postprobenecid accumulation of homovanillic acid in the CSF of depressed patients compared with schizophrenic patients and with normal subjects.

There was a statistically significant positive correlation between age and both 5-hydroxyindoleacetic acid and homovanillic acid and in the group of healthy old volunteers over the age of 70 there was a significantly higher mean value of the acids in comparison with that of the younger control groups.

Postmortem brain frozen at the time of autopsy has been collected from patients dying with HD and compared with postmortem brain from psychotic patients and cases without neuropsychiatric disease, and a number of alterations in neurotransmitters and their biosynthetic enzymes have been found.

MHPG values in CSF may provide an index to norepinephrine metabolism in the central nervous system of man, and doses of l‐DOPA or probenecid, sufficient to substantially elevate CSF levels of the dopamine metabolite, homovanillic acid, failed to alter the spinal fluid content of MHPG.

It is found that values for these substances vary with age, both in psychiatric and neurological groups of patients, which may be crucial for the interpretation of values for CSF monoamine metabolites in clinical studies.

Following the administration of probenecid, cerebrospinal fluid 5-hydroxyindoleacetic acid and homovanillic acid showed a significant positive correlation and their ratio must be considered in the interpretation of results.

5HTP appears to be beneficial in “the syndrome of intention and action myoclonus as a sequel to hypoxic encephalopathy” but may worsen certain other involuntary movements.

It is suggested that neuroleptic-induced tremor may be attributed to serotonergic dysfunction in the brain, and decrease of HVA and increase of cGMP during the treatment might indicate the normalization of dopaminergic-cholinergic imbalance in the head.

The amine metabolites HVA and 5-HIAA in the lumbar CSF of 15 patients with Huntington's chorea were determined and a negative correlation was found between the severity of symptoms and the CSF HVA, but not 5- HIAA levels.

In Parkinson's disease, the concentration of homovanillic acid (HVA) was reduced in lumbar CSF from patients with idiopathic Parkinsonism and post-encephalitic Parkinsonism, and fourteen patients who became functionally independent on treatment with L-dopa had higher 5-HIAA levels than 23 patients who showed no such improvement, suggesting that intact 5-hydroxyltryptamine neurones may be important in the therapeutic response to L- dopa.
