A recent study found that scoring verbal memory tests according to sex can alter who receives a diagnosis of mild cognitive impairment (MCI) by as much as 20%. New research assesses the differences in cognition between males and females after the age of 65. Evidence shows that females tend to have better verbal memory than […]

Dementia: Brain mapping method may predict progression
Does dementia spread gradually and evenly in all directions across the brain, or can it “jump” from one brain area to another? New research helps to settle the question by examining the progression of frontotemporal dementia. Researchers have used MRI scans to improve their prediction of brain atrophy progression in a type of dementia. Frontotemporal […]

Alzheimer’s disease: Brain immune cells may offer new treatment target
One hallmark of Alzheimer’s disease is the massing of tangles of tau protein in the brain. Now, a new study in mice proposes that a type of brain immune cell called microglia drives the tissue damage that is linked to tau clumping. Could deactivating microglia be the key to treating Alzheimer’s disease? Brain scans of […]
Existing blood thinner delays Alzheimer’s disease in mice
An existing blood thinner — used to prevent the formation of blood clots in people at risk of stroke — could help delay the development of Alzheimer’s disease, according to a new study in a mouse model. Could a common blood thinner help people with Alzheimer’s disease? Alzheimer’s disease is the most common form of […]
95% of people think they could develop dementia with age
A global study on attitudes toward dementia has shown that two-thirds of people believe it to be a natural risk of getting older, which could be limiting the help that people seek. The vast majority of people believe that they will develop dementia and that they can do little about it, new research finds. Every […]
Alcohol and dementia risk: A complex relationship
Although alcohol has been popular for millennia, and dementia is increasingly prevalent, scientists are yet to understand the relationship between the two. A recent study sets out for answers. A new study looks at the relationship between dementia, alcohol, genes, and cognitive impairment. With dementia predicted to affect 13.9 million adults in the United States […]
New approach may save brain cells in neurodegenerative diseases
Neurodegenerative diseases, such as Alzheimer’s and Huntington’s, share a mechanism of brain cell damage that could offer a new target for treatment, according to new research in human cells and mice. A newly discovered mechanism of brain cell damage could hold the key to treating several neurodegenerative conditions. A recent Nature Neuroscience study describes how […]
Fluctuating blood pressure may speed up cognitive decline in Alzheimer’s
Just as researchers look for factors that increase the risk of developing Alzheimer’s, they are also interested in finding out which factors may hasten the rate of cognitive decline in people who already have this condition. Fluctuating blood pressure could be one of them, a new study suggests. Could blood pressure influence the rate of […]
Walking patterns may help differentiate types of dementia
The causes of dementia can damage the brain in different ways. Is it possible that these differences may reveal themselves in the way that people walk? A new study that compared walking patterns in people with two types of dementia explored the question. New research suggests a person’s gait may offer clues into the type […]
