Plant-based Diets Lower Risk of Alzheimer’s Disease

A 10-country study of the per capita supply of meat and other animal products (not milk) demonstrated that the higher the supply in the 5 years before diagnosis the higher the risk of Alzheimer's disease.

Cell Phone Use and Alzheimer’s Disease

The Journal of Alzheimer's Disease has reported that researchers exposed normal mice and mice genetically bred to develop Alzheimer's disease (AD) to electromagnetic fields (EMF) at frequencies equivalent to cell phones for 2 hours each day. After 7-9 months those mice exposed to the EMF were actually protected against cognitive impairment, and  AD-like symptoms were reversed…

Mid-life Marital Status and Cognitive Function in Later Life

People living in a relationship with a partner in mid-life (average age 50.4) were less likely than those single, separated, or widowed to develop cognitive impairment later in life. This new research also found that those widowed both at mid-life and later life had a significantly higher chance of being cognitively impaired compared to those…
