People with high cholesterol in their early 40s are more likely to develop Alzheimer’s disease than those with low cholesterol, according to research that will be presented at the upcoming American Academy of Neurology 60th Anniversary Annual Meeting in Chicago, April 12–19, 2008.”Our findings show it would be best for both physicians and patients to attack high cholesterol levels in their 40s to reduce the risk of dementia,” said study author Alina Solomon, MD, with the University of Kuopio in Finland. Solomon collaborated with Rachel Whitmer, PhD, senior author of the study and a research scientist with Kaiser Permanente Division of Research in Oakland, CA. [continue reading…]

Heavy drinkers and heavy smokers develop Alzheimer’s disease years earlier than people with Alzheimer’s who do not drink or smoke heavily, according to research that will be presented at the American Academy of Neurology 60th Anniversary Annual Meeting in Chicago, April 12–19, 2008.“These results are significant because it’s possible that if we can reduce or eliminate heavy smoking and drinking, we could substantially delay the onset of Alzheimer’s disease for people and reduce the number of people who have Alzheimer’s at any point in time,” said study author Ranjan Duara, MD, of the Wien Center for Alzheimer’s Disease at Mount Sinai Medical Center in Miami Beach, FL, and Fellow of the American Academy of Neurology.

Because children often witness spousal abuse, pediatricians have two reasons to routinely screen their patients’ mothers or other caregivers for signs of such physical and emotional domestic violence, a study from the Johns Hopkins Children’s Center suggests.Brief screening is not only a step to protecting a spouse or a partner, it also can reduce the very real collateral health risks experienced by children who see or hear such abuse, the investigators say. Children who live in homes where spousal abuse occurs are at high risk of being abused themselves, according to the American Academy of Pediatrics. [continue reading…]
A team of scientists has unravelled how the brain unconsciously prepares our decisions
Already several seconds before we consciously make a decision its outcome can be predicted from unconscious activity in the brain. This is shown in a study by scientists from the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, in collaboration with the Charité University Hospital and the Bernstein Center for Computational Neuroscience in Berlin. The researchers from the group of Professor John-Dylan Haynes used a brain scanner to investigate what happens in the human brain just before a decision is made. “Many processes in the brain occur automatically and without involvement of our consciousness. This prevents our mind from being overloaded by simple routine tasks. But when it comes to decisions we tend to assume they are made by our conscious mind. This is questioned by our current findings.” (Nature Neuroscience, April 13th 2008)
