Charles Bonnet syndrome associated with a first attack of multiple sclerosis.
ABSTRACT We treated a rare case of Charles Bonnet syndrome (CBS) manifested during temporary blindness in both eyes caused by optic neuritis associated with a first attack of multiple sclerosis (MS).
A 66-year-old Japanese woman became completely blind for 3 months due to optic neuritis after a first attack of MS. During the blind period, she experienced vivid visual hallucinations for about 2 weeks.
The patient had no psychiatric disorders or cognitive impairments; therefore, the visual hallucinations during the period of blindness were indicative of CBS. Unexpectedly, the hallucinations disappeared without treatment following her recovery of vision.
Although rare, visual impairment during a first attack of MS can be associated with visual hallucinations indicative of CBS. The hallucinations can disappear spontaneously with the recovery of vision without treatment.

ABSTRACT: Multiple sclerosis (MS) is a fairly common condition that affects approximately 350,000 people in the United States. 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. 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.The International Journal of Psychiatry in Medicine 02/2003; 33(2):195-9. · 1.15 Impact Factor
