Per DSM-5, which of the following best describes brief psychotic disorder?
Sudden onset of psychotic symptoms in less than a month.
Sudden onset of psychotic symptoms in less than two months.
Sudden onset of psychotic symptoms in less than one year.
Sudden onset of psychotic symptoms in less than six months.
The Correct Answer is A
A. Sudden onset of psychotic symptoms in less than a month. According to the DSM-5, brief psychotic disorder is characterized by a sudden onset of delusions, hallucinations, disorganized speech, or disorganized behavior that lasts at least one day but less than one month, with eventual full recovery.
B. Sudden onset of psychotic symptoms in less than two months. The DSM-5 criteria do not define brief psychotic disorder with a two-month duration. If symptoms persist beyond one month, another diagnosis, such as schizophreniform disorder, may be considered.
C. Sudden onset of psychotic symptoms in less than one year. Psychotic symptoms lasting up to one year are more indicative of schizophrenia or schizoaffective disorder, not brief psychotic disorder.
D. Sudden onset of psychotic symptoms in less than six months. Psychotic symptoms lasting longer than one month but less than six months are consistent with schizophreniform disorder, rather than brief psychotic disorder.

Explanation
A. Restlessness and unable to sit still. This describes akathisia, a movement disorder characterized by an intense feeling of restlessness, often seen as a side effect of antipsychotic medications.
B. Muscle spasms on the face, eyes, neck, and tongue. Dystonia is characterized by sudden, involuntary muscle contractions, often affecting the face, neck (torticollis), eyes (oculogyric crisis), tongue, and jaw. It is a common extrapyramidal side effect (EPS) of antipsychotic medications, particularly first-generation antipsychotics.
C. Tongue rolling and lip smacking. These are hallmark symptoms of tardive dyskinesia, a late-onset movement disorder caused by long-term use of dopamine-blocking agents. It involves involuntary, repetitive movements of the mouth, face, and limbs.
D. Tremors at rest, bradykinesia, and shuffling gait. These symptoms are characteristic of Parkinsonism, an extrapyramidal side effect of dopamine-blocking medications. It mimics Parkinson’s disease and includes rigidity, tremors, and slow movements.
