Neuropsychological Problems Caused by Substance Dependence on Individuals' Brains

It is a widespread condition today that can cause serious social problems. This addiction causes profound changes in individuals' brain functions, paving the way for the development of neuropsychological disorders. At the root of addiction are functional disorders in areas of the brain such as the limbic structures and prefrontal cortex, which are particularly associated with the reward system. The impact on these regions causes serious disruptions in individuals' cognitive processes, such as impulse control, decision-making, memory, and attention. In addition, chemical imbalances occur under the influence of substances, which can lead to mood disorders such as emotional fluctuations, anxiety, depression, and irritability. These neuropsychological changes negatively affect individuals' daily lives and reinforce the cycle of addiction. The structural and functional changes that occur in the brain reveal that addiction has a deep neurobiological basis. Therefore, neuropsychological assessments and interventions are of great importance in the treatment of substance addiction. Research indicates that changes in the brain's reward circuits and decision-making mechanisms accelerate the progression of the addiction process. Consequently, substance addiction is a multifaceted health issue that must be addressed not only psychologically but also in terms of its neuropsychological dimensions. In this context, understanding the effects of addictive substances on the brain and developing effective intervention strategies play a key role in combating addiction.
