[Amino acid composition of cerebrospinal fluid in the epilepsy syndrome].

The aminoacid content of cerebrospinal fluid (CSF) was studied in 51 patients with the epileptic syndrome in conjunction with tumors and cerebral arachnoiditis. In general epileptical seizures CSF demonstrated the highest glutamine content. A drop in the glutamine concentration was seen in hydrocephalus, in rare general and focal seizures. The epileptic syndrome is characterized by an increase in CSF of cystidin, thyrosine and methionine. More pronounced changes in aminoacid metabolism were detected in the epileptic syndrome, in chronic inflammatory brain disorders.
