Dementia

A genetic predisposition to ADHD has been linked to an increased risk of cognitive decline and Alzheimer's disease in old age, according to new research. The findings are the first to associate ADHD genetic risk with age-related cognitive impairment.

A first-of-its-kind meta-analysis has found a significant association between the use of hearing aids and a reduced risk of dementia. The findings suggest that using hearing restoration devices could slow the progression of cognitive decline.

A study looking at post-mortem brain tissue samples has found severe COVID-19 is associated with molecular signs of brain aging. The researchers warn potential long-term neurological problems could emerge in the years following the pandemic.

Scientists at Yale University have uncovered an overlooked mechanism that may be behind the symptoms of Alzheimer’s disease. The team points the finger at small swellings on axons near plaques that build up in the brain, suggesting new drug targets.

In a new study published in Frontiers in Aging Neuroscience, researchers propose urine tests as a potential way to detect Alzheimer's disease. The study suggests formic acid levels in urine could be a useful early-stage biomarker for the disease.

The failure of another massive Phase 3 trial testing an anti-amyloid dementia treatment marks a new twist in the ongoing rollercoaster of research looking for drugs to reduce build-up of the protein commonly thought to be the key cause of Alzheimer's.

New research in Nature Communications has strengthened the link between sleep apnea and dementia, by using preclinical models to demonstrate exactly how breathing disruptions during sleep can cause brain changes associated with Alzheimer's disease.

It's been a rough week for nose-pickers, with headlines loudly declaring "scary evidence" has been found linking Alzheimer's disease to a bit of finger-based nasal exploration. But what is the evidence behind this bold claim and is it really a problem?

Researchers have discovered a unique fat molecule in the brain may have anti-inflammatory effects. Animal studies found levels of the molecule decline with age and their absence could contribute to inflammation associated with neurodegeneration.

New results from a clinical trial lasting over a year have shown playing crossword puzzles may be more effective at slowing age-related cognitive decline than modern video games specifically developed to improve memory.

The first successful results from a trial testing a drug designed to slow symptoms of Alzheimer’s have been revealed, but experts suggest more data is needed to understand exactly how meaningful this treatment will be for patients in the real world.

New research presents the most comprehensive study to date into the long-term neurological problems associated with COVID-19. Tracking 150,000 COVID patients for a year the research found COVID led to a 42% increase in risk of several brain disorders.
