title: Rebound insomnia: a new clinical syndrome.
abstract: Rebound insomnia followed the withdrawal of three benzodiazepine hypnotic drugs, each of which had been administered in a single nightly dose for only short-term periods. The intense worsening of sleep is attributed to the short duration of the action of these drugs. A hypothesis involving benzodiazepine receptors in the brain is proposed in which there is a delay or lag in replacement of endogenous benzodiazepine-like molecules after the abrupt withdrawal of exogenous drugs.
