Their mean age was 58 years in men and 60 years in women. Twenty\u2010four patients spent most of their time at home (i.e. they were housewives, retired, or unemployed). The duration of disease varied from 3 months to 20 years. Fifteen patients brought in fragments of material that they believed to be parasites (\u201cspecimen sign\u201d). Treatment consisted of the antipsychotic drugs pimozide (1\u20136 mg\/d) or olanzapine (5\u201310 mg\/d). Three patients did not return for follow\u2010up. Follow\u2010up varying from 2 months to 7 years was recorded in 24 patients. Two patients were treated with other psychoactive drugs prescribed by psychiatrists for additional psychiatric diagnoses. Control of symptoms was achieved in the majority of patients who underwent adequate follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Delusional infestation is an extremely chronic disease.
