kindling phenomenon
Progressive worsening of withdrawal symptoms with repeated episodes of substance use and cessation, particularly observed with alcohol and benzodiazepines.
Full Definition
The kindling phenomenon describes the neurobiological process by which repeated withdrawal episodes from certain substances, particularly alcohol and benzodiazepines, lead to progressively more severe withdrawal symptoms. Each subsequent withdrawal episode becomes more intense and potentially dangerous, even if the period of use was shorter or the amount consumed was less than previous episodes. This phenomenon is thought to result from neuroadaptive changes in the brain that increase excitability with each cycle of intoxication and withdrawal. Understanding kindling is crucial for addiction medicine practitioners as it influences treatment planning, particularly regarding the need for medically supervised detoxification and long-term management strategies.
Usage
Usage note: Most commonly associated with alcohol and benzodiazepine withdrawal; distinct from general tolerance.
