![]() They analyzed protein levels in people who had donated their brains to science as part of the Memory and Aging Project at Rush University in Chicago. In this new study, published Friday in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, the researchers were able to study human brains. Studies in mice have long shown the protective effect of exercise on the brain once autopsied, but establishing that link in humans has been difficult, It’s all part of how the brain remodels its neural circuits, keeping them healthy. Those proteins need to be in balance with one another in order for the synapse to function optimally,” Casaletto wrote. ![]() “There are many proteins present at the synapse that help facilitate different aspects of the cell-to-cell communication. How to start a healthy morning routine - and stick with it Prior studies have shown that physical activity can reduce risk of dementia by 30% to 80%, “yet we do not understand how this happens at a biological level in humans,” Casaletto explained.įtness expert Dana Santas shares her healthy morning habits and tips for staying on track with a routine. ![]() “All of our thinking and memory occurs as a result of these synaptic communications,” she added. “Synapses are the critical communicating junctions between nerve cells and are really where the magic happens when it comes to cognition,” said study author Kaitlin Casaletto, an assistant professor of neurology in the Memory and Aging Center at the University of California San Francisco, in an email. The protective effect was even found in active older people whose brains showed signs of plaques, tangles and other hallmarks of Alzheimer’s and other cognitive diseases. A new study finds exercise boosts levels of a protein known to strengthen communication between brain cells via synapses, which may be a key factor in keeping dementia at bay. It's not your age that's slowing your metabolism, new research says.
