CNN —Living a healthy lifestyle with a focus on a nutritious diet, regular exercise, minimum alcohol consumption and other healthy habits can help keep your brain sharp into old age, doctors say. But what if your brain already has signs of beta amyloid or tau — two of the hallmark signs of Alzheimer’s and other brain pathologies? Will a healthy lifestyle still protect you from cognitive decline? Not everyone who has signs of Alzheimer’s or vascular dementia goes on to develop cognitive issues, but many do. In fact, “a higher healthy lifestyle score was associated with better cognition even after accounting for the combined burden of brain pathologies,” according to Yaffe and Leng.

Rescuers drilled through rocks and debris to finally reach the men on Tuesday in the Himalayan tunnel where they have been trapped since it collapsed on Nov. 12. Ambulances were waiting at the mouth of the tunnel on Tuesday afternoon to take the men to hospital and R.C.S. "All 41 would experience some post traumatic symptoms like insomnia, recurrent bad dreams, recurrent reliving of the tunnel collapse, anxiety," he said.

Listening to favorite songs could reduce people’s perception of pain, according to a new study published Wednesday in the journal Frontiers in Pain Research. And the most effective pain relievers were found to be sad songs detailing bittersweet and emotional experiences. He was not involved in the latest study but has conducted his own research on the relationship between pain and music. With millions of songs available, one person’s favorite song is likely not the same as another. While he didn’t research chills in this study, Valevicius hypothesized that these sensations might be signs of sensory gating.

☆ New studies shed light on how genes might shape a person’s experience with Covid-19

New research is exploring another dimension to the puzzle of how people experience this infection: genes. Hollenbach says it’s the job of HLA molecules to present pieces of proteins to the immune system so they can be recognized if they’re ever encountered again. The researchers then took a closer look at this group to see if there were any similarities in the genes that coded for their HLA molecules, and there were. So folks with these HLA molecules likely already had some preexisting immunity against SARS-CoV2 and were able to clear the virus before it caused symptoms, Hollenbach said. Genes, Zeberg said, are likely only one part of reason why someone develops long Covid, and there are probably a slew of genes involved.

☆ Cognitive decline accelerates after heart attack, study finds

However, age-related cognitive decline is quite different from Alzheimer’s disease and other dementias and should not be confused with those, experts say. During the course of the research, however, over 1,000 of the participants had an acute myocardial infarction, or heart attack. Past studies found linkThis isn’t the first study to find a connection between accelerated cognitive decline and heart attacks, Smith and Silbert noted. As in the new study, people with heart attacks or angina (chest pain) had annual rates of cognitive decline before the attack similar to those of people who never had a heart attack, but then experienced accelerated cognitive decline, they added. Possible explanations may include depression after having a heart attack, which has been linked to dementia, they said.

Feb 28 (Reuters) - The U.S. Food and Drug Administration neurosciences head Billy Dunn will retire from his role effective immediately, the health regulator told Reuters on Tuesday. Wall Street analysts said Dunn's departure could impact the regulator's stance on neurological drug decisions in the near term, sending down shares of Reata Pharmaceuticals Inc (RETA.O) 30% on Monday when media reports on the exit surfaced. Texas-based Reata is expecting FDA's decision by Tuesday on its drug to treat a rare neuromuscular disorder called Friedreich's ataxia. The departure of Dunn, 53, was announced in an internal message to the agency's employees on Monday. Newly appointed deputy director Teresa Buracchio will also serve in Dunn's role on an interim basis at the Office of Neuroscience, the agency told Reuters.

☆ Forget what you learned in school — the brain might not work in 'regions' after all

NetflixWhite matter ruling how we think and feelBrains are made up of two types of material: white matter and gray matter. The new model from Forkel and her colleagues changes that, giving white matter a much bigger role. One example of how white matter connects unexpected regions of the brain is the incredible injury of a railway worker 150 years ago. White matter may organize the regionsIt's also possible that it is the white matter that directs which region does what in the gray matter, rather than the other way around. This analysis suggests that these studies will have to be rethought to look at the brain as a whole.
