Hypersensitivity in Substance Dependence

Hypersensitivity in substance dependence refers to an exaggerated response of the brain's reward system to substance-related cues, often resulting in cravings and relapse. This phenomenon is linked to neuroadaptations caused by prolonged substance use, where normal stimuli become less rewarding while substance-related stimuli become overly significant. Common signs include heightened emotional reactions, physical sensitivity, and amplified cravings when exposed to triggers. Addressing hypersensitivity involves cognitive-behavioral therapy (CBT) to identify and manage triggers, pharmacotherapy to stabilize neural pathways, and mindfulness practices to regulate emotional responses. Understanding hypersensitivity is crucial for creating targeted relapse prevention strategies, as it highlights the importance of addressing both environmental and neurological components of addiction.
