Post-acute-withdrawal syndrome

Post-acute-withdrawal syndrome (PAWS), or the terms post-withdrawal syndrome, protracted withdrawal syndrome, prolonged withdrawal syndromes describe a set of persistent impairments that occur after withdrawal from alcohol, opiates, benzodiazepines, antidepressants and other substances. Infants born to mothers who used substances of dependence during pregnancy may also experience a post-acute withdrawal syndrome. While post-acute withdrawal syndrome has been reported by those in the recovery community, there have been few scientific studies supporting its existence. Because of this, the disorder is not recognized by the Diagnostic and Statistical Manual of Mental Disorders or major medical associations.

Drug abuse, including alcohol and prescription drugs, can induce symptomatology which resembles mental illness. This can occur both in the intoxicated state and during the withdrawal state. In some cases these substance-induced psychiatric disorders can persist long after detoxification, such as prolonged psychosis or depression after amphetamine or cocaine abuse. A protracted withdrawal syndrome can also occur with symptoms persisting for months after cessation of use. Benzodiazepines are the most notable drug for inducing prolonged withdrawal effects with symptoms sometimes persisting for years after cessation of use. Severe anxiety and depression are commonly induced by sustained alcohol abuse which in most cases abates with prolonged abstinence. Even moderate alcohol sustained use may increase anxiety and depression levels in some individuals. In most cases these drug-induced psychiatric disorders fade away with prolonged abstinence.

Symptoms can sometimes come and go with wave-like reoccurrences or fluctuations in severity of symptoms. Common symptoms include impaired cognition, irritability, depressed mood, and anxiety; all of which may reach severe levels which can lead to relapse.

The protracted withdrawal syndrome from benzodiazepines can produce symptoms identical to generalized anxiety disorder as well as panic disorder. Due to the sometimes prolonged nature and severity of benzodiazepine withdrawal, abrupt withdrawal is not advised.
