Problem

A 30-year-old woman presents with 'weird behavior' for the past 8 months. She says, "The enemy is trying to communicate via Morse code with their sleeper agents to disrupt the nation's economy," which is why she sits on the rooftop the whole night looking for unusual activity. She can also hear the enemy talk over the radio when she switches between different frequencies. She was recently fired from her job at a local newspaper company due to her irrational beliefs and obsessions. She has no significant history, and she does not take regular medications. She does not smoke, drink, or use illicit drugs. Family history is significant for bipolar disorder in her brother. Vital signs are normal. Physical examination shows a flat affect and incoherent speech. She is prescribed risperidone in addition to psychotherapy. She returns 6 months later with a marked resolution of symptoms. Which adverse effects is most likely?
