Hey so sorry to hear that

Brain function degeneration is normal when aging. Do you have any family history of Parkisons or Alzheimers?

Are they taking medications that will affect the brain? Anti-depressants? sleeping pills etc.

Now, we still don't quite understand why aging causes brain function to decline but most likely reason is due oxidative stress. Basically the free radicals generated over the years causing damage to the nerves and neurons in the brain.

An unfortunate thing is, most cells in our body repair and regenerate but not the nerve cells. Once they are damaged, it's likely to be permanent. That's why the medications for Alzheimers don't alway work, and can only slow down disease progression and not cure it.

To help reduce oxidative stress, they need to be taking antioxidants - Vitamin A,C,E are the common ones. Grapeseed extract is good or Pycnogenol (Maritime Pine Bark Extract) are good, and another one is ALCAR (Acetyl-L-Carnitine).

Please note: ALCAR is not the same as L-carnitine. I'm not sure if you can find ALCAR in Malaysia, but it's available from overseas.

For more on supplements for the elderly, I have recently reviewed 100+ studies and written an article on that. In the article, I listed out 6 supplements I think are most crucial for the seniors.

Please feel free to read it and leave me a comment if you have any questions. PM me if you would like a more detailed chat.
