Catecholamine level in cerebrospinal fluid of epileptics

We estimated catecholamine levels in CSF of 15 epileptics and 75 non-neurological patients utilizing a high performance liquid chromatograph with a highly sensitive fluorometer and found the following results: The dopamine (DA) levels in males were significantly higher than those in females, while norepinephrine (NE) levels in males were the same as in females. The DA levels were significantly lower and NE levels significantly higher in epileptics than in non-neurological patients. DA and NE in petit mal patients were on the average lower than in grand mal patients, but untreated grand mal patients had higher NE levels. These results suggest that epilepsy may be associated with a disturbance of DA and/or NE metabolism or release in the brain.
