What is alcohol addiction?
In the human brain there are pleasure centers, allowing humans to experience pleasure and feel motivated. Therefore, “learning” occurs naturally when reward and pleasure occur together. In this case, the person “learns” that with alcohol, they could just feel good and bypass all the unwanted anxiety, fidgety and restless feelings they had before.
Trouble begins when the “downer” affects everything in a systemic way.
Therefore, inhibitions and ability to foresee natural consequences to one’s behavior also go “down,” making the interpersonal lives of those afflicted with alcohol dependence very unpleasant.
Alcoholism has both short term and long term negative consequences on psychological and physiological health of the person. Trouble with concentration, shakiness, irritability, insomnia, nightmares, decreased sexual desire and sexual performance, obesity, trouble metabolizing sugar, and depression and extreme anxiety in the form of paranoia are among the side effects of alcoholism. Liver damage, hepatitis, brain atrophy, and Alzheimer dementia are also noted as long term health hazards related to alcoholism.
