Did you know?

Degenerative diseases—including cancer, glaucoma, Parkinson's, diabetes, arthritis, and leprosy—are usually contrasted with infectious diseases (diseases caused by bacteria, viruses, fungi, and protozoa). However, many infectious diseases (Lyme disease, AIDS, etc.) can cause a body or body part to degenerate, and infective organisms play a part in some degenerative diseases. Some degenerative diseases can be controlled; some can even be cured. But no one has yet discovered a way to reverse such degenerative conditions as multiple sclerosis, emphysema, or Alzheimer's.
