Blood serotonin and tryptophan in Tourette syndrome

1 Aug 1990

Abstract excerpt

Blood serotonin and tryptophan levels were studied in 1,440 individuals. These included patients with Tourette syndrome (TS), attention deficit hyperactivity disorder (ADHA), or ADHD with a family history of TS (ADHD 2 degrees TS); relatives (parents, sibs) of these patients; other patients with TS-like disorders; and controls. There were significant decreases in the serotonin/platelet ratio (P = 0.0001) and in...
