I remember seeing a show discussing studies involving identical twins...one with Alzheimer's and one without. The research with identical twins is still ongoing and I don't know if any conclusions have been drawn, yet. I have heard that keeping the mind active also helps delay Alzheimer's in those prone to the disease. Alzheimer's is a very real concern for my DH. He is the youngest of 8 children. Two of his sisters have died from complications of Alzheimer's and his brother is currently in a nursing home with the disease. His parents had their first child in 1911...DH was born near the end of 1938. They always considered the older 5 as one set of children (1911-1922) and the remaining 3 as the second set (1930-1938). One of the sisters (b.1922) developed early onset Alzheimer's and died at the age of 54. The other sister who had Alzheimer's died at age 82. His brother is currently 82. I cannot convince DH to go paleo, but he is paying more attention to what he's eating so there is hope. The doctor has encouraged him to supplement with Vitamin E, Folic Acid, etc., since the doctor doesn't feel this would do any harm. Of the 4 "children" living, the eldest sister (almost 90) is in fair physical health and excellent mental health, the 82 year old has Alzheimer's, the 70 year old (female) is in good health (as much as can be expected on SAD and high BP), and my DH, who's almost 62, is like his 70 year old sister but he also copes with paraplegia due to spinal cord trauma. Maybe someday I can get DH to go paleo...sure hope so. Just my 2¢ on the subject. Betty Ann mailto:[log in to unmask] "In a cat's eyes, all things belong to cats." English Proverb
