Partridge describes a woman, age sixty-one, who suffered from the delusion that insects infested her house, hair, and ears. Her husband fully participated in this delusion, but her thirty-seven-year-old daughter did so only when in the mother's home. The author therefore describes this as a case of folie à deux et demie. Eventually the mother was treated by a prefrontal leucotomy and lost the delusion. Partridge maintains that the other two affected persons 'have been fully cured in that neither has any current symptoms while both have insight'.
