Charles Bonnet syndrome: Visual hallucination and multiple sclerosis

Multiple sclerosis (MS) is a fairly common condition that affects approximately 350,000 people in the United States (1). It is associated with various neuropsychiatric symptoms including cognitive and behavioral symptoms. However, visual hallucinations are rare in multiple sclerosis without the presence of cognitive deficits (2). We are describing the case of a 40-year-old married white female with isolated complex visual hallucinations compatible with the Charles Bonnet syndrome (CBS). The patient was successfully treated with the atypical antipsychotic olanzapine.
