Substance-Induced Neuroadaptation

Substance-induced neuroadaptation refers to the brain’s process of adapting to the presence of a substance over time, which often results in tolerance and dependence. As the brain becomes accustomed to the drug, its neurochemical systems adjust, leading to the need for increasingly higher doses to achieve the same effect. This adaptation can also result in withdrawal symptoms when the substance is removed. The concept of neuroadaptation is central to understanding addiction, as it highlights the physiological changes that underpin the cycle of craving, use, tolerance, and withdrawal. Treatment strategies focus on reversing or mitigating these neuroadaptive changes through gradual reduction of substance use and the use of medications that support recovery.
