 Syn: -- Distemper; ailing; ailment; malady; disorder; sickness; illness; complaint; indisposition; affection. -- Disease, Disorder, Distemper, Malady, Affection. Disease is the leading medical term. 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.
