If a herpes virus does turn out to be one cause of Alzheimer's Disease then the amino acid Lysine could be a useful addition to any treatment regimen as Lysine is quite effective at treating cold sores. Lysine has been shown to be safe at levels that will control cold sores and can cross the blood / brain barrier as can the antioxidants alpha lipoic acid and melatonin which have both shown benefits of varying degrees in Alzheimer's patients and rodent models. Of course the patient studies seem to be of more practical value for those that feel that rodent models of Alzheimer's diease are a poor substitute for the real thing.
Coconut oil also has the ability to inhibit some herpes viruses and there is increasing anecdotal evidence that it can improve the Alzheimer's disease state at doses that are reasonably practical.
In the case of melatonin, it is not only an antioxidant itself, but it also acts to activate the bodies own antioxidant system, something that not all antioxidants are capable of. Melatonin also acts in an anti-inflammatory role which is an important aspect of Alzheimer's disease progression. Melatonin has also shown the ability to protect the human brain from many of the known damaging effects to the brain caused by Alzheimer's disease. Melatonin also can help alleviate some of the sleeplessness symptoms associated with AD. Another benefit shown in human studies is melatonin's ability to alleviate the symptom refered to as "Sundowning".
The good news is that not only are these supplements generally considered safe, they are readilly available, relatively cheap and are purported to have many other health benefits also!
