Study: Adults with diabetes more prone to dementia Sept 2011
For 11 years, Japanese researchers followed more than 1,000 people, ages 60 and older.
They found that those with diabetes at the outset were 35 percent more likely to develop Alzheimer's.
Those with the most severe diabetes had more than triple the risk.

Deficiency of Vitamin D has the following graph

Diabetes is in a vicious circle with vitamin D.

Low vitamin D increases diabetes, and diabetes decreased vitamin D even more.

Vitamin D spirals lower and lower

Overview Cognition and vitamin D

• Cognitive decline, dementia, and Alzheimer's Disease are all associated with low vitamin D levels.

Toward a Theory of Vitamin D Disease Associations includes the following Sept 2011

List of associations seen recently ( more to be in future versions of this page)

• Parkinson's ==> osteoporosis
• Skin wrinkles ==>fragile bones
• Dental problems==> depression (pregnancy)
• Smoking ==> weak bones
• Prostate Cancer ==> Osteoporosis
• No molar ==> 12X increase in Breast Cancer
• Psorasis ==> Metabolic Syndrome on the web

Possible predictions

• Watching TV or reading books ==> myopia
• Lung cancer ==>
• HIV ==>
• Diabetes ==> Depression
• Surgery ==>cognitive problems which last for many months
• Disease ==> Insomnia
• Several diseases now associated with aging (but may be due to low vitamin D) ==>cognitive decline
