<unk> due to substance withdrawal refers to the neurological condition which results from repeated withdrawal episodes from sedative–hypnotic drugs such as alcohol and benzodiazepines. Each withdrawal leads to more severe withdrawal symptoms than in previous episodes. Individuals who have had more withdrawal episodes are at an increased risk of very severe withdrawal symptoms, up to and including seizures and death. Long-term use of GABAergic-acting sedative–hypnotic drugs causes chronic GABA receptor downregulation as well as glutamate overactivity, which can lead to drug and neurotransmitter sensitization, central nervous system hyperexcitability, and excitotoxicity.
