Relationship of response to sleep deprivation and carbamazepine in depressed patients

Abstract
– The responses of 16 patients with major depressive disorder to one night's sleep deprivation and a subsequent double-blind, placebo-controlled trial of carbamazepine were compared. There was a significant association between the presence or absence of an antidepressant response to each of these treatments. Further studies are required to assess the clinical utility of this relationship and whether it is based on antidepressant response to any agent or is more specific to carbamazepine.
