Breakdown of myelin may be the cause of Huntington's disease

Last month, Dr. George Bartzokis, director of the UCLA Memory Disorders and Alzheimer's Disease Clinic, suggested in the journal Alzheimer's & Dementia that the breakdown of a type of myelin that develops late in life promotes the buildup of toxic amyloid plaques long associated with Alzheimer's disease.

Green tea may help prevent bone destruction in arthritis

In rheumatoid arthritis, a person's own immune system attacks the joints by activating the synovial tissue that lines the body's movable joints, causing inflammation, swelling, pain and eventually erosion of the bone and cartilage and deformation of the joint.
