There may be a way to protect brain energy to preserve cognition — and the secret could lie on your plate. Think fish and seafood, meat, non-starchy vegetables, berries, nuts, seeds, eggs and even high-fat dairy products.
University of Missouri researchers are now testing just how powerful these foods can be. They’ve found that a high fat, low carb diet — known as the ketogenic diet — may not only preserve brain health but also stop or slow the signs of cognitive decline for those at higher risk of developing Alzheimer’s disease.
Deep brain stimulation, a method where specific brain regions are activated using implanted electrodes, is a well-established approach for treating movement disorders such as Parkinson’s disease. Researchers led by Christian Kell from Frankfurt University Medicine as well as Nils Warneke and Katrin Neumann from Münster University Hospital have now successfully alleviated severe stuttering in a person with developmental stuttering using this method for the first time. The researchers are now preparing a study to test the therapy on additional individuals who experience severe stuttering.
Adding genomic sequencing to newborn blood screening would detect hundreds of additional childhood conditions, providing much earlier diagnosis and treatment, according to a new study. A baby’s genome, which stays with them for life, could also be re-examined if a health issue arises during their lifetime.

A novel disease prevention strategy — targeting a mosquito that spreads the dengue virus — significantly reduces both the mosquito numbers and cases of disease across a community, finds a major new study.
