Rural and minority dementia patients face disparities in access to neurologists
March 20, 2024
A study of nearly 95,000 Washington state residents found that people living outside of urban areas as well as Native American and Hispanic people face longer travel distances to be seen by neurologists. The researchers said these disparities could be contributing to delayed diagnoses, which can res...

Biomarkers of the middle-aged brain predict cognitive health in old age
March 19, 2024
The middle-aged brain could provide a window into future cognitive health. A team reviewed evidence from human and animal studies suggesting that middle age -- commonly considered as the period between 40 and 60 or 65 years of age -- marks a shift in brain aging. They argue that more research should...

New study reveals breakthrough in understanding brain stimulation therapies
March 15, 2024
Researchers show that non-invasive brain stimulation can change a specific brain mechanism that is directly related to human behavior.
A healthier diet is linked with a slower pace of aging, reduced dementia risk, study shows
March 14, 2024
A healthier diet is associated with a reduced dementia risk and slower pace of aging, according to a new study. The findings show that a diet-dementia association was at least partially facilitated by multi-system processes of aging. Until now, the biological mechanism of this protection was not wel...

Alzheimer's drug fermented with help from AI and bacteria moves closer to reality
March 14, 2024
Researchers combined artificial intelligence and chemical biosensors to ferment the precursor of an Alzheimer's drug in bacteria.
Blast-related concussions linked to higher Alzheimer's risk
March 14, 2024
U.S. veterans of the wars in Afghanistan and Iraq who suffered mild traumatic brain injury from exposure to explosive blasts were found to have changes in cerebrospinal fluid proteins that are typically seen in people who develop Alzheimer's disease, according to researchers....

Genetic condition haemochromatosis linked to higher levels of disease in older people
March 13, 2024
A largescale new study has found that some people whose genetics are linked to the common iron overload condition haemochromatosis have substantially greater levels of liver, musculoskeletal and brain disease than previously reported, especially at older ages....

Integrity of blood-brain barrier depends on protein that is altered in some neurodegenerative diseases
March 13, 2024
Defects in the blood vessel network of the central nervous system have been linked to early symptoms of neurodegenerative diseases such as Alzheimer's disease and amyotrophic lateral sclerosis (ALS). It is this complex vascular network that provides the necessary nutrients -- especially glucose and ...

'Curved' walking and a depth camera: New tool detects early cognitive decline
March 12, 2024
Gait impairments often are prevalent in the early stages of cognitive decline. Researchers quantitatively compared straight walking and curved walking -- a more natural yet complex activity -- in healthy older adults and adults with mild cognitive impairment (MCI). A depth camera detected and tracke...

Researchers identify gene involved in neuronal vulnerability in Alzheimer's disease
March 11, 2024
Early stages of neurodegenerative disorders are characterized by the accumulation of proteins in discrete populations of brain cells and degeneration of these cells. For most diseases, this selective vulnerability pattern is unexplained, yet it could yield major insight into pathological mechanisms....
