Dementia

Becoming more forgetful and feeling slower in your thinking is normal in older age. But when these changes are more than you’d expect for your age it might be a sign of mild cognitive impairment. So does that mean you’ll soon develop dementia?

Glucose levels have been linked with the accelerated aging of the human brain in a new study by researchers in China, highlighting the benefits of healthy eating and exercise early in life to keep your brain fighting fit in old age.

Elevated levels of GDF15 in the peripheral blood were associated with dementia risk in a recent study, with researchers arguing the chemical could serve as a handy biomarker for future cognitive decline.

A new study has found that the stride length of a dog’s front legs can be used to accurately diagnose their cognitive decline. Because a person’s change in gait can play a significant role in spotting early signs of Alzheimer's disease or dementia.

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.

Many people manage their symptoms with antihistamines bought from a pharmacy. But recent headlines have raised a worrying question: could some of the medicines used to relieve hay fever symptoms increase the risk of dementia?

A new study suggests that as many as 20% of Parkinson's disease cases may be something else entirely, highlighting the importance of test accuracy before treatment is even on the cards. As to why it's been misdiagnosed – well, it's complicated.

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.

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.
