The Hippocampus: Linking Stress to Anhedonia, Addiction, & Relapse (Barr, Bray, Forster, 2018)

Описание: I. The Addiction Cycle and Withdrawal
Addiction is a chronic loop of withdrawal and craving.
Severe withdrawal features anxiety and stress responses.
These negative states act as a powerful relapse engine.

II. Hippocampal Anatomy
The dorsal hippocampus handles rapid spatial learning.
The ventral hippocampus acts as the emotional center.
It regulates anxiety and coordinates stress adaptation.

III. The Reward System Hijack
The ventral hippocampus connects to the reward system.
Psychostimulants amplify dopamine responses to drug cues.
The brain heightens cravings for drug environments.

IV. Neurochemical Dysregulation
Chronic drug use disrupts serotonin levels in the brain.
Lower serotonin levels drive severe withdrawal anxiety.
Stress hormone imbalances trap the brain in dysphoria.

V. Structural Plasticity Changes
The brain generates new neurons in the dentate gyrus.
Psychostimulants can impair this neurogenesis process.
Impaired growth makes drug memories harder to forget.
Diminished new neurons hinder drug-free habit forming.

VI. The Goal of Treatment
Recovery requires rebalancing hippocampal chemical systems.
Treatment aims to restore brain and emotional homeostasis.
Normalizing neurogenesis reduces relapse vulnerability.
