Addiction

Addiction is a neuropsychological disorder categorized by insistent use of a drug, despite substantial harm and other negative consequences. Repetitive drug use often alter brain function in ways that continue thirst, and weakens (but does not completely negate) self-control. This phenomenon, (drugs reshaping brain function), has led to an understanding of addiction as a brain disorder with a difference of neurobiological and psychosocial factors that are implicated in addiction's development. Classic signs of addiction embrace obsessive engagement in rewarding stimuli, obsession with substances or behavior, and persistent use despite undesirable consequences. Habits and patterns associated with addiction are typically categorized by instant gratification (short-term reward), coupled with tardy deleterious effects (long-term costs).
