(See Etiology.). During withdrawal from alcohol, the loss of GABA-A receptor stimulation causes a reduction in chloride flux and is associated with tremors, diaphoresis, tachycardia, anxiety, and seizures. In addition, the lack of inhibition of the NMDA receptors may lead to seizures and delirium.ess than 50% of alcohol-dependent persons develop any significant withdrawal symptoms that require pharmacologic treatment upon cessation of alcohol intake. The lifetime risk for developing delirium tremens (DTs) among chronic alcoholics is estimated at 5-10%.
