 [with-draw´al]
1. a pathological retreat from interpersonal contact and social involvement, as may occur in avoidant, schizoid, or schizotypal personality disorders.
2. the removal of something.
3. a substance-specific substance-induced disorder that follows the cessation of use or reduction in intake of a psychoactive substance that had been regularly used to induce a state of intoxication. Specific withdrawal syndromes include those for alcohol, amphetamines or similarly acting sympathomimetics, cocaine, nicotine, opioids, and sedatives, hypnotics, or antianxiety agents. Called also abstinence syndrome, withdrawal symptoms, and withdrawal syndrome.



The usual reactions to alcohol withdrawal are anxiety, weakness, gastrointestinal symptoms, nausea and vomiting, tremor, fever, rapid heartbeat, convulsions, and delirium (see also delirium tremens). Similar effects are produced by withdrawal of barbiturates and in this case convulsions occur frequently, often followed by psychosis with hallucinations. Treatment of withdrawal consists of providing a substitute drug such as a mild sedative, along with treatment of the symptoms as needed. Parenteral fluids are often required.

Another RCT which compared the efficacy of high doses of OROS methylphenidate (180 mg/d) with placebo over 24 weeks in male patients with ADHD and amphetamine addiction found that methylphenidate was more efficacious than placebo in improving ADHD symptoms, amphetamine consumption and drop-out rate (Konstenius et al., 2014).The third and final explanation is an attempt to give an account specifically of the results observed regarding substance withdrawal. Even if the SUD is a consequence of ADHD, a small improvement in ADHD symptoms would not have a strong enough effect to bring about a reduction in substance use.
