Alzheimer's disease

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?

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 uncovered evidence of “synaptic down-selection” as we sleep, suggesting our nightly shut-eye is a perfect opportunity to prune back any neurological hedges that went wild during the day.

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.

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.
