Chronic exposure to high doses of alcohol can result in profound changes in the morphology, proliferation, and survival of neurons. For example, new neurons normally are constantly generated from neural stem cells throughout the life of an organism. In alcohol binge-drinking rats, however, both the proliferation of neural stem cells and the survival of neurons produced from the stem cells during alcohol exposure are decreased (Nixon and Crews 2002). The prefrontal cortex and, particularly, the orbitofrontal cortex7 have central roles in executive https:\/\/ecosoberhouse.com\/article\/alcoholics-heart-problems-cardiomyopathy\/<\/a> functions, such as decisionmaking. Accordingly, deficits in these brain areas may impact motivational circuits, impairing the ability of the organism to inhibit impulsive behavior and thereby further contributing to pathological drug-seeking behavior (Jentsch and Taylor 1999). More recently, imaging techniques were used to show that alcohol-dependent humans have smaller amygdala volumes than nondependent individuals and that smaller amygdala volume in alcohol-dependent humans is predictive of subsequent alcohol relapse (Wrase et al. 2008).<\/p>\n Distinguishing between these concepts is essential in recommending the right treatments. Sometimes, severe withdrawal symptoms require monitoring from doctors in a hospital setting. It occurs when a person has difficulty stopping substance use or engaging in a behavior that provides some type of benefit. Estimates of the economic costs attempt to assess in monetary terms the damage that results from the misuse of alcohol.<\/p>\n\n
