What is the difference between wilson's syndrome and wilson's disease?

Completely different: Wilson's syndrome is a condition of low body temperature and slow body metabolism, which overlaps with symptoms of hypothyroidism. Wilson's disease is a genetic defect of copper export, leading to accumulation of copper initially in the liver, and then by other tissues (especially the brain).

Two very different : Wilson's disease is an inherited disorder of copper accumulation in the body with liver and neuropsychiatric sypmtoms. Wilson's syndrome is an alternative medicine concept regarded as a hoax by mainstream medicine. It has low body temperature and allegedly impaired conversion of thyroid T4 to t3 (liothyronine).
