The most likely diagnosis Phencyclidine intoxication
Reason :
Some of the hallmarks of a substance-induced problem are the presence of aggressive behavior involving fighting, vertical or horizontal nystagmus, agitation, impaired judgment, and impaired social or occupational functioning. Hallucinations may be present, but they are not always; if hallucinations are present, the patient usually knows that they are substance-induced. In this case, the patient did not report a feeling of paranoia. There is no basis for a diagnosis of antisocial personality disorder, and there is no evidence of psychosis. A careful history should include an inquiry regarding any substances used.
What is Psychotic disorder ?
Drug-induced psychosis, also known as substance-induced psychotic disorder, is simply any psychotic episode that is related to the abuse of an intoxicant. This can occur from taking too much of a certain drug, having an adverse reaction after mixing substances, during withdrawal from a drug, or if the individual has underlying mental health issues.
Antisocial personality disorder :
Antisocial personality disorder is characterized by a pattern of disregard for and violation of the rights of others. The diagnosis of antisocial personality disorder is not given to individuals under the age of 18 but is given only if there is a history of some symptoms of conduct disorder before age 15.
Brief Psychotic Disorder has a sudden onset of at least one psychotic symptom ( delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior). The psychotic symptoms last less than 1 month and are followed by a full recovery.
Schizophrenia :
Schizophrenia is characterized by some combination of hallucinations, delusions, and extremely disordered thinking and behavior that impairs daily functioning, and can be disabling.
