Marked nervous defects, such as imbecility, idiocy, epilepsy, manias, cannot be more than mentioned here. They may be present from birth, or may develop later. Their treatment belongs entirely to the field of the physician, neurologist, and psychopathologist. Treatment of mental defects should begin at the earliest possible age; some forms are curable if treated early.
