This small change can have a big effect.
The latest brain health research comes from a study published on Jan. 7 in. Researchers studied brains from 404 deceased participants between the ages of 70 and 80 that were donated to science as part of the Rush Memory and Aging Project conducted in Chicago. They also collected data onExamination of that brain tissue found that those participants who were more active and moved more later in life had higher levels of a protein that has been shown tothrough synapses, CNN reports.
"The more physical activity, the higher the synaptic protein levels in brain tissue. This suggests that every movement counts when it comes to brain health,", PhD, an assistant professor of neurology in the Memory and Aging Center at the University of California San Francisco, told CNN in an email, adding that her team recommends aiming for 150 min per week—or 20 minutes per day—of physical activity.
The research team's findings focus on an element of brain health concerning the passage of electrical impulses between neurons."Synapses are the critical communicating junctions between nerve cells and are really where the magic happens when it comes to cognition," Casaletto wrote in the email."All of our thinking and memory occurs as a result of these synaptic communications.
When it comes to slowing or stopping the onset of dementia, the body must repair and replace proteins on synapses in the brain and keep them in the correct proportions."There are many proteins present at the synapse that help facilitate different aspects of the cell-to-cell communication. Those proteins need to be in balance with one another in order for the synapse to function optimally," Casaletto wrote.
According to experts connected to the study, the research team's finding of a positive correlation between physical activity and protective proteins could be important for addressing dementia in the future.
