Ca. Altamura et al., PLASMA AND PLATELET EXCITATORY AMINO-ACIDS IN PSYCHIATRIC-DISORDERS, The American journal of psychiatry, 150(11), 1993, pp. 1731-1733
Plasma and platelet levels of excitatory amino acids were measured in
38 psychiatric out-patients and in 19 comparison subjects; the patient
s had DSM-III-R diagnoses of organic mental disorders (N=3), mood diso
rders (N=15), schizophrenia (N=13), and anxiety disorders (N=7). The g
lutamate plasma levels were significantly higher in the patients with
mood disorders than in the comparison group.
