title: Haloperidol administration in humans lowers plasma nerve growth factor level: evidence that sedation induces opposite effects to arousal.
abstract: Studies reported in recent years have indicated that the level of nerve growth factor (NGF), in both the brain and in the bloodstream, increases following stressful events and anxiety-associated behaviour. These observations prompted us to investigate whether an anti-arousal drug would induce an opposite effect. We have reported that the administration of haloperidol (HA), a neuroleptic drug clinically used for psychiatric disorders, decreases NGF levels in the hypothalamus of adult male mice. In the present study, we showed that HA reduced the basal NGF plasma levels in 8 neuroleptic-free schizophrenic patients. These observations strengthen the hypothesis that NGF may play a functional role in stress-coping responses.
