Researchers Question Whether Alzheimer’s Proteins Can Spread Through Donated Blood

Researchers Question Whether Alzheimer’s Proteins Can Spread Through Donated Blood

Few things in medicine are as routine, or as life-saving, as a blood transfusion. Patients receive them after accidents, during surgery, and through cancer treatment, and most never give it a second thought. Now a group of researchers is asking whether donated blood could carry more than blood. A new review in The Lancet examines whether proteins…

Daily Tomato Paste Linked to Sharper Focus and Changes in Brain Scans

Daily Tomato Paste Linked to Sharper Focus and Changes in Brain Scans

Most of us use tomato paste for flavor and little else. A recent clinical trial tested what happens when it becomes a daily habit, and the effects appeared in two places: on cognitive tests and on brain scans. The changes were modest and the evidence is early, but the results raise a bigger question about…

Vitamin D Linked to Better Cognitive Scores in People With Mild Cognitive Impairment and Poor Sleep

Vitamin D is one of the most widely used supplements, and most people take it for their bones. A new study suggests it may also be tied to something else: how well people with early memory problems perform on a cognitive test. The finding is small, and it comes with a catch you should know…

A New Nanoparticle Drug Reversed Memory Loss in Mice With Alzheimer’s After Just Two Shots

Alzheimer’s disease has resisted decades of research, so a study reporting improved memory and behavior after just two injections deserves a careful look. The results come from mice, not people, and that distinction matters. But the way this treatment works is unusual, and it raises a question researchers have debated for years. Here’s what the…

New Study Maps the Shared Genetic Roots of OCD, Tourette’s, and Autism

As a physician, one of the biggest hurdles in addressing conditions like obsessive-compulsive disorder or Tourette’s syndrome is the persistent myth that they stem from psychological stress. While the medical community has known for years that these conditions are inherited, the exact biological blueprint has remained hidden—until now. A major genetic study has finally mapped…

Researchers Pinpoint the Brain Protein That Drives Age-Related Memory Loss

Researchers Pinpoint the Brain Protein That Drives Age-Related Memory Loss

As we get older, many of us notice small slips in our memory—forgetting a name, misplacing keys, or struggling to find the right word. For decades, the medical community accepted these cognitive changes as an unavoidable part of aging. But recent research suggests we have been looking at brain aging the wrong way. Scientists have…

A Little Movement in Your 40s and 50s Could Pay Off for Your Brain Later

A Little Movement in Your 40s and 50s Could Pay Off for Your Brain Later

When patients ask me how to protect their memory as they age, they often expect me to recommend crossword puzzles or the latest brain-training app. While mental exercises certainly have their place, the most effective strategies for preserving your cognitive function later in life actually have very little to do with your brain itself. The…

Aspartame and Common Sweeteners Tied to 16 Years of Brain Aging

Aspartame and Common Sweeteners Tied to 16 Years of Brain Aging

As a doctor, I spend a significant amount of time talking to patients about sugar intake. We know that excess sugar drives weight gain, inflammation, and metabolic disease. To avoid these issues, many people reach for zero-calorie sugar substitutes, assuming they are making a smart, healthy choice. But replacing a known problem with synthetic chemicals…

The Real Reason More Women Get Alzheimer’s: What New Research Reveals

The medical world brushed off a staggering statistic: nearly two-thirds of all Alzheimer’s patients are women. We were told it was simply because women live longer than men, but I have seen firsthand in my clinic that this outdated math does not add up. Today, groundbreaking science is finally exposing the real biological reasons behind…
