Shingles is a viral infection caused by the varicella-zoster virus, which also causes chickenpox. If you've had chickenpox, the virus stays in your body and can reactivate later in life as shingles at any age, though most commonly after 50. While caused by the same virus, shingles and chickenpox are not the same illness. They present differently because, while chickenpox is the initial infection, if and when the virus reactivates, it travels along nerve pathways to the skin, producing shingles.

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.

Anyone living with schizophrenia understands the true limitations of current treatment options. Antipsychotics remain the single leading treatment for the disorder, and they are riddled with undesirable side effects. Weight gain, tardive dyskinesia, and excessive drowsiness are a few. Much research is devoted to expanding the range of medication options, and few academics have pursued other avenues. However, there is a possibility that treatment for schizophrenia can be approached through cellular methods if long-term research validates early signs of hope.

Sometimes it's a fall that brings a broken hip and a loss of mobility. Or memory problems that bubble into danger. Or the death of the partner who was relied upon for care.The need to move to a nursing home, assisted living facility or another type of care setting often comes suddenly, setting off an abrupt, daunting search. It's likely something no one ever wanted, but knowing what to look for and what to ask can make a big difference.

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.

Young, two-month-old lab mice housed with older, 18-month-old mice showed really impaired cognition. Researchers exposed young mice raised in a sterile, microbe-free environment to gut bacteria from old mice, causing the younger animals to perform worse on cognitive tests, as if they had prematurely aged, just like the cohoused mice.

You know that moment when you walk into a room and completely forget why you went there? Or when someone you've known for years walks up to you at the grocery store and their name just... vanishes from your brain? Last week, I spent ten minutes searching for my reading glasses while they were sitting on top of my head. My first thought wasn't "oh, silly me." It was "Is this how it starts?"

To make their discovery, researchers examined donated eye tissue from more than 100 people who had died with Alzheimer's, mild cognitive impairment or no signs of dementia. They were looking specifically for C. pneumoniae, because previous research has already linked it to Alzheimer's. The bacteria has also been detected in brain tissue from patients who died with the condition, sometimes found close to the sticky amyloid plaques and tangles believed to drive memory loss and confusion.

I woke up and had a panic attack that morning because the next 365 days can be crucial because of what he has got,

Researchers used data from two health studies to track the caffeine-drinking habits of more than 130,000 people over four decades. They found that drinking 2-3 cups of coffee or 1-2 cups of tea a day was associated with the greatest reductions in rate of cognitive decline, a result that held true even in people with a genetic variant called APOE4, which is associated with Alzheimer's disease.

For families living with neurodegenerative disease, the hardest part is not always the diagnosis. It is the slow erosion that follows: memory fading, personality shifting, independence shrinking. It unfolds quietly. First, forgotten appointments. Then repeated questions. Then moments when a familiar face no longer feels familiar. The illness does not isolate itself to one body. It rearranges the lives around it.
