Older women who walked or partook in moderate-to-vigorous exercise each day had a reduced risk of developing mild cognitive impairment and dementia.
People exposed to the Camp Fire California wildfire in 2018 showed significant brain and cognitive function changes many months after the event. Findings add to the growing body of evidence that supports a growing phenomenon known as "climate trauma".
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.
Of patients with dementia, 7% had chronic kidney disease while 9% had albuminuria, a urinary marker for kidney disease. Chronic kidney disease was associated with a 51% increased risk of developing dementia.
An intranasally delivered oxytocin derivative helped improve cognitive function and reduced cognitive impairment in mouse models of Alzheimer's disease.
Older adults who experience insomnia are at greater risk of developing memory deficits and long-term cognitive impairments.
First responders at the World Trade Center who experience cognitive impairment and PTSD have a different presentation of white matter in the brain compared to first responders with cognitive impairment without PTSD. Researchers say the findings point to a new and specific form of dementia for those responders with PTSD.
Severe COVID-19 infection results in cognitive impairment similar to that sustained by natural aging between the ages of 50 to 70, and is equivalent to losing 10 IQ points.
Study reveals a bi-directional link between daytime napping and cognitive decline associated with Alzheimer's disease. Researchers say longer, more frequent napping was associated with worse cognition after one year, and worse cognition was linked to longer and more frequent daytime naps.
College football players are 5 times more likely to report cognitive impairment, 2.5 times more likely to experience recurrent headaches, and 65% more likely to have cardiovascular problems in their lifetime than their non-football playing peers. Additionally, mortality from brain and other nervous system cancers was 4 times higher in former college football players than the general population.
Type 1 interferon is a major diver of cognitive impairment and memory loss in mouse models of Alzheimer's disease. Blocking IFN reversed both cognitive impairments and memory deficits in the animal models.
Regular exercise may break inflammation associated with long-COVID that leads to diabetes, depression, and cognitive impairment in the months following infection.
