Plasma amino acids in attention deficit disorder

Psychiatry Res. 1990 Sep;33(3):301-6. doi: 10.1016/0165-1781(90)90046-8.

Abstract

This study examines plasma amino acids in a group of 28 patients meeting DSM-III criteria for attention deficit disorder (ADD) and 20 control subjects. Compared with controls, the ADD subjects had significantly lower levels of phenylalanine, tyrosine, tryptophan, histidine, and isoleucine. These data suggest a general deficit in amino acid transport, absorption, or both.
