Only Male Mice Show Sensitization of Handling‐Induced Convulsions Across Repeated Ethanol Withdrawal Cycles

Abstract

Male and female mice exposed to the same number of cycles of EtOH withdrawal demonstrate differences in expression of seizures. Males show the typical sensitization of seizures, or kindling response, which has been reported clinically as well as in animal models, but females do not. The reason for the lack of seizure sensitization in female mice remains to be elucidated, but may be related to sex differences in alcohol effects on excitatory/inhibitory neurotransmission, rather than to hormonal or blood alcohol level differences.
