Image of a lab worker Body can 'heal dementia itself'  - BBC  Left:  The scientists used the body's natural defenses against disease.  The researchers isolated antibodies against beta peptide and injected these into patients with early Alzheimer's disease on a monthly basis for six months. Five Alzheimer's disease patients treated with the experimental therapy showed improvement in tests. At the end of the six months, levels of beta peptide in cerebrospinal fluid fell by 30%, and the level of beta peptide in the blood shot up 233%, suggesting that the treatment was working. Although brain, or cognitive function improved only slightly in four patients, it did not worsen.

But in recent years there has been some worrying evidence emerging about a possible harmful effect of Vitamin A, even at quite low doses. Research has shown that long term intakes of Vitamin A at around twice the RDA, may be linked to weaker bones and an increased risk of bone fracture.
