Post-acute-withdrawal syndrome
Post-acute withdrawal syndrome (PAWS) is a hypothesized set of persistent impairments that occur after withdrawal from alcohol,[1][2] opiates, benzodiazepines, antidepressants, and other substances.[3][4][5] Infants born to mothers who used substances of dependence during pregnancy may also experience a PAWS.[6][7] While PAWS has been frequently reported by those withdrawing from opiate and alcohol dependence, the research has limitations. Protracted benzodiazepine withdrawal has been observed to occur in some individuals prescribed benzodiazepines.[8][9]

Post-withdrawal syndrome, protracted withdrawal syndrome, prolonged withdrawal syndromes
Drug use, 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 from amphetamine, cocaine, opioid, and alcohol use, causing prolonged psychosis, anxiety or depression. A protracted withdrawal syndrome can occur with symptoms persisting for months to years after cessation of substance use. Benzodiazepines, opioids, alcohol, and any other drug may induce prolonged withdrawal and have similar effects, with symptoms sometimes persisting for years after cessation of use. Psychosis including severe anxiety and depression are commonly induced by sustained alcohol, opioid, benzodiazepine, and other drug use which in most cases abates with prolonged abstinence. Any continued use of drugs or alcohol may increase anxiety, psychosis, and depression levels in some individuals. In almost all cases drug-induced psychiatric disorders fade away with prolonged abstinence, although permanent damage to the brain and nervous system may be caused by continued substance use.[10]
Cause[edit]
The syndrome may be in part due to persisting physiological adaptations in the central nervous system manifested in the form of continuing but slowly reversible tolerance, disturbances in neurotransmitters and resultant hyperexcitability of neuronal pathways.[23][24][25][26] However, data supports "neuronal and overwhelming cognitive normalization" in regards to chronic amphetamine use and PAWS.[27][28] Stressful situations arise in early recovery, and the symptoms of post acute withdrawal syndrome produce further distress. It is important to avoid or to deal with the triggers that make post acute withdrawal syndrome worse. The types of symptomatology and impairments in severity, frequency, and duration associated with the condition vary depending on the drug of use.
Treatment[edit]
The condition gradually improves over a period of time which can range from six months to several years in more severe cases.[29][30]
Flumazenil was found to be more effective than placebo in reducing feelings of hostility and aggression in patients who had been free of benzodiazepines for 4 to 266 weeks.[31] This may suggest a role for flumazenil in treating protracted benzodiazepine withdrawal symptoms.
Acamprosate has been found to be effective in alleviating some of the post acute withdrawal symptoms of alcohol withdrawal.[32][33] Carbamazepine or trazodone may also be effective in the treatment of post acute withdrawal syndrome in regards to alcohol use.[34][35][36] Cognitive behavioral therapy can also help the post acute withdrawal syndrome especially when cravings are a prominent feature.[37]
