Abstract

The adolescent brain is particularly vulnerable to the effects of cocaine exposure due to ongoing neurodevelopment especially in areas that are crucial for cognitive and emotional regulation. This review explores the multifaceted impact of cocaine on neuroplasticity during adolescence, thereby highlighting both the immediate and long-term consequences of drug exposure. Key findings from recent studies indicate that cocaine use during adolescence leads to significant alterations in synaptic plasticity, dendritic spine morphology, and neurotransmitter systems, which may persist into adulthood and contribute to addictive behaviors. Additionally, the interaction between genetic predispositions, environmental stressors, and drug exposure is emphasized. The review also analyzed the risks of early-life stress and social isolation on cocaine-induced neuroplasticity, which can render anxiety-related behaviors and lead to neurological changes. Future studies should incorporate longitudinal design to understand the long-term trajectory of neuroplasticity induced by cocaine. This paper can provide some suggestions to the development of prevention and intervention programs for adolescents at risk.
