Effects of Addiction on the Brain
8
Flashcards
0/8
Prefrontal Cortex
Addiction reduces the function of the prefrontal cortex, impairing decision-making and impulse control, making it more difficult to resist the addictive substance or behavior.
Nucleus Accumbens
Addiction increases dopamine release in this area, reinforcing the desire and motivation to seek out the addictive substance or behavior.
Amygdala
Addiction causes increased sensitivity to stress and cues associated with the addictive substance, which can lead to an enhanced experience of cravings.
Hippocampus
Addiction can lead to altered memories and learning processes, causing associative memories that increase cravings when exposed to specific cues related to the addiction.
Ventral Tegmental Area (VTA)
Addiction results in an overactivation of this area leading to increased production of dopamine that reinforces addictive behaviors.
Cerebellum
Addiction can disrupt the cerebellum's role in motor control and cognitive functions, potentially leading to impaired coordination and balance.
Anterior Cingulate Cortex (ACC)
Addiction can lead to dysregulation of the ACC, impacting emotional processing and attention, contributing to the inability to resist impulses and cravings.
Basal Ganglia
Addiction can lead to changes in the basal ganglia, affecting habit formation and the reward system, potentially leading to compulsive substance use or behaviors.
