title: Increased dopaminergic activity in restricting-type anorexia nervosa.
abstract: Eye blink rate, a peripheral measure of central dopaminergic activity, has been investigated in 20 female anorexic "restricting-type" patients and 16 healthy female subjects. A significantly increased blink rate was found in the anorexic patients. A significant positive correlation between blink rate and duration of illness was also found.
