Serum Folate and Vitamin B12in Epileptics with and without Mental Illness

Considerable interest is at present focused on the possibility of an association between mental illness in epileptics and metabolic abnormalities resulting from the anticonvulsant drugs they have been taking; in fact it has been suggested that these drug-induced abnormalities may be actually causative of the psychiatric disorders. For a good summary of this literature the interested reader is referred to Reynolds (1968).
