Abstract

Interferon- is used in patients with multiple sclerosis to reduce autoimmunity; although other psychiatric side-effects are common, in contrast to interferon-alpha, psychosis has been reported only once. A patient with multiple sclerosis developed auditory hallucinations, paranoid delusions, and increased aggressiveness after 16 months of treatment with interferon-β-1b, 250 μg every other day. He responded after about one month to antipsychotic treatment, but tended to relapse upon dose reduction, and after 2 years still needs antipsychotics to control his symptoms. Because there was no change in his magnetic resonance imaging between pre- and post-treatment with interferon, we concluded that psychosis was more related to interferon treatment than to the underlying disease.
