Final answer:
Symptoms of substance/medication-induced mental disorders tend to diminish over a period of days to weeks after abstinence, although the exact time can vary widely depending on several factors.
Step-by-step explanation:
Symptoms of substance/medication-induced mental disorders can vary significantly based on the substance involved, the duration of use, individual physiology, and the amount consumed. Generally, after abstinence from the substance, symptoms may begin to subside. For substances that require an incubation period, symptoms can take hours to days to manifest, which can make it difficult for individuals to associate these symptoms with the substance consumed.
With neuroleptic drugs, which are used to manage psychotic symptoms such as hallucinations and delusions, symptoms can diminish gradually over a period of days. Withdrawal symptoms, which are typically the opposite of the effects of the drug, can be quite distressing. The discontinuation of sedative drugs, for instance, often results in arousal and agitation. The development of tolerance and psychological dependence is also a consideration in substance/medication-induced mental disorders.
In summary, the typical timeframe for the remission of symptoms following abstinence is variable but often falls within a few days to a few weeks, in line with options (a) and (b) of the multiple choices provided. The exact duration can be influenced by a multitude of factors.
