High-fat diets promote early inflammatory responses in the brain via an immune pathway associated with diabetes and neurodegenerative diseases. The findings suggest a link between metabolic dysfunction and cognitive impairment.
Machine learning algorithms can effectively recognize patterns in a patient's neuroimaging data that are specific to rare forms of dementia, allowing for early diagnosis and monitoring of disease progression.
Researchers report six minutes of high-intensity exercise on a regular basis can slow brain aging and delay the onset of neurodegenerative diseases such as Alzheimer's and Parkinson's disease. High-intensity exercise increases the production of BDNF, a protein implicated in memory, learning, and brain plasticity, which could protect the brain from age-related cognitive decline.
Older adults who face social isolation have a 28% increased risk of developing dementia than those who have frequent social interactions.
The opportunities for a healthy lifestyle are unequally distributed and being socially disadvantaged with a higher risk of developing Alzheimer's disease.
Changes in body weight over a person's lifetime may predict dementia later in life, a new study reveals.
While exercise and mindfulness help older adults stay physically fit and mentally well, they may not have such a strong beneficial impact on cognition as previously believed.
Older adults with cognitive decline who have higher levels of vitamin D in their brains had better cognitive function than their peers with lower levels of vitamin D.
Gene usage in the brains of those who suffered severe COVID-19 infections was similar to that observed in the aging brain. Researchers say COVID-19 is associated with molecular signatures of brain aging.
In those with hearing loss, using hearing aids or cochlear implants was associated with a long-term reduction of cognitive decline by 19% and a 3% improvement in cognitive test scores.
Researchers report abstaining from drinking alcohol can actually increase dementia risks. Low to moderate alcohol consumption may help to reduce dementia risks.
Previous TBI increased the risk of frontotemporal dementia in those without a genetic risk factor for FTD. Additionally, researchers found those with FTD tend to be less educated than those with Alzheimer's disease.
