University of California, San Francisco (UCSF) scientists have developed a form of neurological pacemaker that adapts in real time to a patient’s walking and could address one of the most disabling and hard-to-treat symptoms of Parkinson’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.

Paraquat is one of the world’s most widely used herbicides. It’s also highly toxic, and some research points to a link with Parkinson’s disease. But what does the evidence really say?

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.

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.

Researchers have developed a urine-based screening tool that may help identify individuals who are most likely to later receive an autism diagnosis. It potentially opens the door to earlier, more accessible assessment and support networks.

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.

Stormy skies could send more patients to the emergency room, according to an analysis of weather systems and medical data by researchers in Hungary.

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.
