What's the difference between a disease, a disorder and a syndrome?
- SYNDROME: this term is applied to a constellation of symptoms that occur together or co-vary over time. The term carries no direct implications in terms of underlying pathology.
- DISORDER: like a syndrome, refers to a cluster of symptoms, but the concept includes the idea that the set of symptoms is not accounted for by a more pervasive condition. There is no implication of cause or origin.
- DISEASE: a disorder where the underlying cause or origin is known.
