Alzheimer's disease

People taking fish-oil supplements in an effort to shield their brain from Alzheimer's disease might be better off investing that money in their diet, with a two-year study finding that omega-3 pills offer no protection from cognitive decline.

A report on an individual patient has prompted scientists to ask whether psilocybin, the psychedelic compound in magic mushrooms, could have unexpected effects on the ageing brain.

People with Alzheimer’s disease who took the over-the-counter supplement glucosamine were 25% more likely to die within five years than those who didn’t. This new study investigates its role in speeding up cognitive decline.

In the US, 6,000 women enter menopause every day, or 1.3 million in a year. Now, a study sheds light on the brain connectivity changes that happen in this phase, paving the way to finally understanding and ideally treating midlife cognitive decline.

One of the biggest mysteries in neuroscience is why women account for nearly two-thirds of Alzheimer’s cases. Now, we may be a step closer to understanding it, as an overlooked part of the brain appears to fail as estrogen abandons it.

New research suggests that blood biomarkers in combination with self-reported memory concerns could offer an early clue to how Alzheimer’s disease develops across the life course, meaning midlife could be a critical window for promoting brain health.

Many of us probably don't get a lot of time to put pen to paper these days, but a new study suggests we should be paying more attention to how we write – because changes in a couple of key areas could be early red flags of cognitive decline.

Sleep loss is one of the most challenging symptoms of dementia and Alzheimer’s. New research has now likened poor sleep to a canary in a coal mine, an early symptom of neurodegeneration that could serve as a biomarker to identify the disease.

After an analysis of data from over 131,000 people, researchers found that drinking coffee and tea daily seems to guard against the development of Alzheimer's disease and other forms of cognitive decline - caffeine may be the key protective compound.

Scientists have uncovered an intriguing link between infection and brain health, finding that a common bacterium may advance cognitive decline. It's the latest evidence suggesting that bacteria and infections play a key role in destroying our brains.

For some time, we've known that it's rare to see people with both cancer and Alzheimer's diseases. Now, scientists believe they may have found why, discovering a molecule in cancer cells that clears problem proteins from the brain.

Using the largest sample of super-agers to date, scientists have found convincing evidence that supports what many of us have suspected: Longevity isn’t just about healthy lifestyle choices, but also a good draw in the genetic lottery.
