Has anyone had a good result from using coconut oil in treating the symptoms of Alzheimers, dementia, or Parkinsons?

My husband was cured of his dementia after taking coconut oil. I started him on it after watching a video of Dr. Mary Newport whose husband had Alzheimer's and was helped by taking the coconut oil. I started giving it to Bruce in place of butter and other oils.

The change started within 3 hours starting with clearer speech and thinking patterns, and within 2 months, taking him from a man who couldn't do anything for himself to someone who is back to normal. The tremors took about 3 months and were the last sign to leave.

I know that coconut oil may not help everyone, but I wonder if, in almost every instance, there is some food that could help the starving brain.

We call Bruce's recovery a miracle, but it was brought about by natural means. Are there others with similar stories?
