+ Tai Chi and Alzheimers

Vitamin E
In 2005 a study came out that showed that taking excess of 400U of Vitamin E was associated with an increased risk of death. This, however, has been contradicted by recent studies, where 4000 U seemed to be safe. They also found that patients with existing Alzheimer's disease actually had a slight slow down in their disease when they took Vitamin E at 4000 Units daily. Since there do not seem to be any adverse effects, I would recommend using this in Alzheimer's patients. However there is no proof that it can be preventative, and it is probably not a god idea to use Vitamin n E for that reason.
Other vitamin and mineral supplements have been studied and do not seem to be of any benefit (more on this in a post to come soon).

DDT Metabolites
As mentioned in thee previous post, a higher level of DDT metabolites was found in Alzheimer's patients. Stay organic!

Cognitive Training
Several studies have confirmed the "use it or loose it" philosophy of cognition. The more you "exercise" your brain, the less deterioration. Now a study has shown that a 5-6 week course consisting of a total of 10 hours of training (including memory, speed of reasoning, and processing resulted in improved thinking and decreased deterioration that actually lasted 10 years AFTER the training. Unfortunately there was no effect on memory; but these subjects had significant improvement in activities of every day living.

Tai Chi
Interestingly, Tai Chi also seemed to have lasting effects on improved thought processing and activities of daily living. This relatively simple activity that even moderately physically impaired  patients can participate in is worthwhile.

In summary, use your brain, exercise and eat well. Do Tai Chi if you can, and if you have developed Alzheimer's take 4000U of vitamin E daily.
