The article I found talks about how the hippocampus over time may shrink and you could develop Alzheimer's disease and experience memory loss. Dr Michael Valenzuela from the University of NSW found that people with a more active lifestyle could prevent shrinkage. So you could be causing damage to your hippocampus simply by watching TV. I watch TV, as do a lot of people I assume, and while reading this I wonder how much is too much? With the growing number of Alzheimer's patients, it is important to know that there could be a way to prevent Alzheimer's in a natural way. By getting outside once in a while I might be able to prevent my memories from fading away.
Ive also come across some findings from alzheimer's disease research that suggests exercise for prevention, but with a different mechanism. Recent studies have linked alzheimer's disease to diabetes, and some have even gone as far as suggesting that alzheimer's is actually a type of diabetes. A particular type of toxic amino acids, amyloid beta-derived diffusible ligands (ADDL's) have been shown to be a partial cause for alzheimer's disease. Researchers treated cells from the hippocampus with insulin which acted to block ADDL's from entering the synapses and damaging the cells (Klein, 2009). This might explain why insulin-deficient type-2 diabetics are up to 3 times more likely to develop alzheimer's disease than non-diabetics (Neergaard, 2009). Since proper diet and excercise are crucial for prevention and management of diabetes, a healthy lifestyle may also reduce the risk of alzheimer's disease.
as i was investigating the discussion about shrinkage in the hippocampus i learned that their might possibly be antidepressants,ssri's in particular, that may actually have a shrinking affect on this part of the brain. They may not only prenvent the actual shrinkage but they may in fact reverse the loss by spurring nuerogenis- the birth of new nuerons in the hippocampus. so my thoughts in this conversation are that yes getting outside and away rom the TV is a good preventative measure to shrinking in the hippocampus but their actually might be another type of treatment that will produce the same desired results. my thoughts also go to the idea that if shrinkage in the hippocampus causes alzheimers and antidepressants have the opposite efects then maybe useing antidepressants as a preventative measure might also be a viable option. http://pn.psychiatryonline.org/cgi/content/full/38/17/24
Alcohol can also cause the hippocampus, as well as other parts of the brain, to shrink and lose its ability to maintain memories, especially in teens. This has to do with the fact that the human brain isn't done developing until around the age of twenty or so. Talk to a buddy who's been drinking somewhat heavily for years. The effects are pretty obvious. Its sad to see the new, "perma-fried" versions of them.

It wouldn't accept my html for the links, so copy/paste. Sorry for the inconvenience.
