What is a Neurotransmitter?
A neurotransmitter is a chemical substance in the brain that helps transmit signals between nerve cells (neurons). Neurotransmitters play a critical role in regulating mood, emotions, and behavior. Common neurotransmitters include dopamine, serotonin, and norepinephrine, which influence feelings of pleasure, motivation, and stress response.
In addiction, substances like drugs and alcohol can disrupt the normal functioning of neurotransmitters, leading to dependence as the brain adjusts to the presence of the substance. Recovery from addiction often involves restoring the balance of neurotransmitters through therapy, medications, and lifestyle changes to support healthy brain function.
