Alcohol withdrawal syndrome
Alcohol withdrawal syndrome is a set of symptoms that can occur when an individual reduces or stops alcoholic consumption after long periods of use. Prolonged and excessive use of alcohol leads to tolerance and physical dependence. The withdrawal syndrome is largely a hyper-excitable response of the central nervous system to lack of alcohol. Symptoms typical of withdrawal include agitation, seizures, and delirium tremens.
Sedative-hypnotics, such as alcohol, are well known for their propensity to induce physiological dependence. This dependence is due to alcohol-induced neuro-adaptation. Withdrawal is characterized by neuropsychiatric excitability and autonomic disturbances. Dependence on other sedative-hypnotics can increase the severity of the withdrawal syndrome.
