Compared with people who reported drinking no coffee, those reporting 3-4 cups per day had longer telomeres, while those reporting 5 or more cups per day did not show the same association.
A groundbreaking study found that adults who sit for 10 or more hours daily face a significantly higher risk of dementia compared to those who sit less. The research, which tracked over 50,000 adults using wearable devices, revealed that the risk increases dramatically after crossing that 10-hour threshold.
Most people will forget a name, misplace their phone, or lose track of a conversation at some point. Usually, those moments pass without much thought. But for many adults, especially as they age, small lapses can trigger a much deeper fear: Is this the beginning of cognitive decline? As a neurologist, I hear this concern often. And as a researcher, I have learned something important: Worry about cognition and cognitive disease are not the same thing.
It's easy to feel hopeless when someone has Alzheimer's, and to think that small interventions won't make a difference. That's understandable - and thankfully not true. "This symptom can be effectively treated with behavioral interventions as well as medication, which is FDA-approved for the treatment of agitation in Alzheimer's disease," Palekar said. To get to that point, he recommended discussing any agitation-like symptoms with the patient's medical provider.
But questions remain about the accuracy and uncertainty of these tests, and experts caution that the assays aren't ready for prime time. While the results here are encouraging, they are not yet at the level of having significant clinical benefit for individual patients, says Corey Bolton, a clinical neuropsychologist and an assistant professor of medicine at Vanderbilt University Medical Center, who was not involved in the new study.
