Alzheimer's markers predict start of mental decline

Tweet

Scientists at Washington University School of Medicine in St. Louis have helped identify many of the biomarkers for Alzheimer's disease that could potentially predict which patients will develop the disorder later in life. Now, studying spinal fluid samples and health data from 201 research participants at the Charles F. and Joanne Knight Alzheimer's Disease Research Center, the researchers have shown the markers are accurate predictors of Alzheimer's years before symptoms develop.

Fish oil may stall effects of junk food on brain

Tweet

Data from more than 180 research papers suggests fish oils could minimise the effects that junk food can have on the brain, a review by researchers at the University of Liverpool has shown.

The team at the University's Institute of Ageing and Chronic Disease reviewed research from around the world to see whether there was sufficient data available to suggest that omega-3s had a role to play in aiding weight loss.
