Acute mental disorders are mostly treated in the form of hospitalization, 24-hour supervision of the patient and protective restraint until there is a clear diagnosis. If there is really no way to get the patient to cooperate with treatment or to quiet down, or even if there is self-injury or injury, small amounts of drugs that stabilize the patient’s mood, such as the anxiolytic diazepam, alprazolam, clonazepam, etc., and also some antipsychotic drugs, such as haloperidol, olanzapine, etc., need to be applied. Once the cause of acute psychiatric disorder is determined, the first step is to treat the cause, such as organic causes, traumatic brain injury, brain tumors, or long-term physical illnesses that lead to mental disorders. Secondly, if the disorder is caused by a stressful event, such as an acute stress reaction, antipsychotic medication should be applied for a period of time.
