Seniors Health News:Low sugar in brain exacerbates Alzheimer's ♦ Lycopene may ward off kidney cancer ♦ Unexpected outcomes for elderly couples who stop driving ♦ Plus More

Low sugar uptake in brain appears to exacerbate Alzheimer's disease  A deficiency in the protein responsible for moving glucose across the brain's protective blood-brain barrier appears to intensify the neurodegenerative effects of Alzheimer's disease, according to a new mouse study. The research suggests that targeting the protein called GLUT1 could help prevent or slow the effects of Alzheimer's, especially among those at risk for the disease Continue Reading
Lycopene may ward off kidney cancer in older women  A higher intake by postmenopausal women of the natural antioxidant lycopene, found in foods like tomatoes, watermelon and papaya, may lower the risk of renal cell carcinoma, a type of kidney cancer, scientists report. Continue Reading
Unexpected outcomes for elderly couples who stop driving  Even if just one member of a couple stops driving, negative consequences result for both the driver and non-driver, a study concludes. The researcher recommends that the elderly and their adult children carefully discuss and plan for the transition to driving cessation.Continue Reading
Neuroscientists identify new way several brain areas communicate  Neuroscientists have identified a new pathway by which several brain areas communicate within the brain's striatum. The findings illustrate structural and functional connections that allow the brain to use reinforcement learning to make spatial decisions. Knowing how these specific pathways work together provides crucial insight into how learning occurs. It also could lead to improved treatments for Parkinson's disease. Continue Reading
Poor heart function could be major risk for Alzheimer's disease   Heart function has been associated with the development of dementia and Alzheimer's disease through a new study. Participants with decreased heart function, measured by cardiac index, were two to three times more likely to develop significant memory loss over the follow-up period Continue Reading
