Disorder mean? much the same, with perhaps some slight reference to an irregularity of the system. Distemper is now used by physicians only of the diseases of animals. Malady is not a medical term, and is less used than formerly in literature. Affection has special reference to the part, organ, or function disturbed; as, his disease is an affection of the lungs. A disease is usually deep-seated and permanent, or at least prolonged; a disorder is often slight, partial, and temporary; malady has less of a technical sense than the other terms, and refers more especially to the suffering endured. In a figurative sense we speak of a disease mind, of disordered faculties, and of mental maladies. [1913 Webster]
