Abstract
- The possibility of disturbed dopamine and serotonin metabolism in the progressive myoclonus epilepsy (PME) occurring in Finland (a type of PME without Lafora bodies) was examined. Both basal concentrations of HVA and 5-HIAA in the CSF and their increase after oral probenecid administration were studied in 19 PME patients and in 19 age- and sex-matched control patients. The control patients had grand mal epilepsy but not myoclonus or ataxia. The basal value of HVA was significantly reduced and that of 5-HIAA was also slightly reduced in the PME patients as compared to the values of the epileptic controls or to those of 26 nonepileptic controls. The concentrations of HVA and 5-HIAA also seemed to correlate with the severity of the PME. The most severely affected patients had generally the lowest values. After oral probenecid this trend was also seen when the increases of HVA and 5-HIAA were expressed per microgram CSF probenecid, i.e. the mildly affected PME group showed higher increases in response to probenecid than the most severely affected PME group. The PME patients had higher probenecid levels in the CSF than the epileptic controls.
