Bottom Line
Psychosis is a symptom of various pathologies, not only psychiatric disorders, and could indicate a disease process that requires treatment by other specialists. Normal basic lab results, vital signs, and physical examination should not supersede a careful history when considering a further medical workup. Anti-N-methyl-D-aspartate receptor encephalitis can cause psychosis and should be considered in the evaluation of patients who present with an atypical psychotic prodrome.
