Cognitive functioning

One of the brain’s biggest benefits from exercise – the birth of new neurons – may not even require any movement. Instead, the beneficial “packages” circulating in the blood after working out can be successfully transferred to others.

Boosting levels of a certain molecule that declines with age restored the function of hundreds of brain genes and reversed memory loss in Alzheimer’s disease models, fixing the RNA splicing errors that drive damage to critical neurons.

Listening to or playing music later in life could do more than lift your spirits – it might also help keep your mind sharp. A large study has found that older adults who regularly engage with music have significantly lower rates of cognitive decline.

We've known for some time that obesity affects the brain, but now scientists have found that it's where you carry it that matters most. Deep visceral fat around organs has the biggest impact on brain aging, affecting a suite of cognitive functions.

Soccer heading has long been suspected of impacting brain health, but where and how it leaves a mark has been a blind spot. Now, for the first time, scientists have a clear picture of the damage and why repeated impacts can impair cognition over time.

A new study reveals that people's beliefs in the health benefits of supplements might not come from science, but from clever labelling. Phrases like “boosts brain function” can make people believe a supplement can prevent conditions like dementia.

A weekend of burgers, fries and hot dogs will probably have you thinking more about your waistline than your brain, but a new study has found that just a few days eating high-fat foods is enough to rewire your memory hub. But the damage can be undone.

While artificial sweeteners were once touted as healthy alternatives to sugar, research continues to prove otherwise. Yet another study has now come along saying that six popular sweeteners might be truly terrible for our brains.

The FDA has approved a new version of an Alzheimer’s disease drug that can be given as a quick at-home weekly injection, offering patients a more convenient option than lengthy infusion-center visits. It will be widely available from October 6, 2025.

In a landmark study, scientists have found that a specific rhythm in our brains determines how well we process the world around us. This discovery could change how we understand and treat focus, attention and memory in Alzheimer's disease and ADHD.

A comprehensive review looking at autistic adults over the age of 40 has found that as many as 90% of cases are undiagnosed, leading older adults – who are more susceptible to poor mental and physical health outcomes – with no recognition or support.

Just a few days after scientists announced we're at a pivotal tipping point in Alzheimer's disease research, a team has made a huge breakthrough, proving that mitochondrial dysfunction fuels memory loss. Then they engineered a way to restore it.
