The key findings are restlessness, anxiety, and fidgeting which started 2 days ago in the setting of recently started antipsychotic medication for schizophrenia. This presentation is most consistent with akathisia, which is a movement disorder characterized by subjective feelings of restlessness and objective motor findings like fidgeting that can occur as a side effect of antipsychotic medications.
