Dementia

Dementia is not a specific disease. It is a descriptive term for a collection of symptoms that can be caused by a number of disorders that affect the brain. People with dementia have significantly impaired intellectual functioning that interferes with normal activities and relationships.

What Causes Dementia?

Dementia occurs due to loss of brain function that occurs with certain diseases. It can affect several brain functions such as memory, thinking, language, planning, behavior and judgement. Dementias are usually progressive and worsen with time. They usually are degenerative and non reversible.

Poor sleep may flag early Alzheimer’s risk in genetically vulnerable older women

Poorer subjective sleep quality was linked to worse visual memory and greater limbic tau burden in older women with higher genetic risk for Alzheimer’s disease. The findings suggest sleep complaints may help identify women at elevated risk for early AD-related brain and cognitive changes, but larger longitudinal studies are needed.

New AI framework maps systemic obesity damage at cellular resolution

Researchers at Helmholtz Munich, the Ludwig Maximilians University Munich (LMU) and collaborating institutions have developed an artificial intelligence (AI) framework that maps disease-related changes throughout the entire mouse body at cellular resolution.

Early electronic advance directives reduce burdensome end-of-life care

Advance directives document patient preferences for future care, including end-of-life. An analysis in the Journal of the American Geriatrics Society found that older patients with an advance directive that had been uploaded into the electronic health record at least six months before death were 25% less likely to experience potentially burdensome end-of-life care (19.9% versus 26.8%) and 31% less likely to have died in the hospital (23.2% versus 32.1%).

Researchers uncover new genetic links influencing blood lipid composition

DZNE researchers have generated new insights into how the human genome shapes the chemical composition and concentration of blood lipids.

Women may face greater cognitive impact from dementia risk factors

Researchers from the University of California San Diego School of Medicine found that women not only experience a higher burden of certain modifiable dementia risk factors, but also appear more vulnerable to their effects on cognitive function.

Facial micromovements may help doctors measure pain more accurately

Researchers at Rutgers University-New Brunswick are working to measure pain more accurately beyond the single, subjective question patients are often asked: "On a scale of 1 to 10, how bad is your pain?"

Pennington and Vanderbilt launch major study on childhood obesity treatment

Pennington Biomedical Research Center, in collaboration with Vanderbilt University Medical Center, has launched a research study, the COACH trial, to test different ways to help children and their families improve their health through lifestyle changes delivered by primary care clinics in communities in Louisiana and Tennessee.

Researchers use living human cells on a chip to study memory loss

A University of Bath-led project has secured £500,000 to develop a first-of-its-kind 'organ-on-chip' device that replicates connections between the brain, gut and pancreas.

Discovery of memory switch in the brain opens new avenues for dementia therapies

"Why do patients with dementia or cognitive decline remain stuck in past memories?" KAIST researchers have identified, for the first time in the world, the existence of a "neural switch" in the brain that selectively retrieves the most recent memories.

Blood metabolite patterns could reveal dementia risk in midlife

Research shows that blood metabolite profiles can indicate dementia risk, offering a potential tool for early detection and prevention of cognitive decline.

Silent heart attacks may speed cognitive decline

Research shows hidden heart attacks accelerate cognitive decline, highlighting the need for better identification of cardiovascular risks to brain health.

Research identifies significant spike in neurological disorders during the covid-19 pandemic

In 2021, neurological diseases affected 3.40 billion individuals worldwide, corresponding to 43.1 % of the global population. In China, rapid demographic shifts and lifestyle changes have contributed to a continued rise in the burden of stroke, dementia, and Parkinson's disease-a trend expected to persist.

Healthy brain maintenance protects cognitive skills from early Alzheimer's effects

A healthy brain may help protect thinking and memory skills from the early effects of Alzheimer's disease, a new study has found.

New research maps the biological toll of drinking

A new review published in the journal Addiction confirms drinking causes substantial harm to health. Some of those harms may be reversible if the person reduces or stops drinking.

Study warns of rising cognitive impairment following a heart attack

The chance of developing cognitive impairment was significantly higher for people who have had a heart attack, according to a study published today in Stroke, the peer-reviewed scientific journal of the American Stroke Association, a division of the American Heart Association.

Fine particle pollution may quietly damage brain function over time

The air pollution we breathe daily could be harming more than just our lungs and hearts. New research from McMaster University suggests that fine particles from traffic, industry and wildfire smoke is linked to worse cognitive function.

Adding GLP-1 drugs to behavioral interventions silences food noise

New research presented at this year's European Congress on Obesity in Istanbul, Turkey, shows that use of obesity drugs alongside behavioral interventions leads to a larger drop in so called 'food noise' than in those using the behavioral therapy alone.

Study explains how APOE2 gene protects the brain against Alzheimer's disease

People who carry the APOE2 version of the apolipoprotein E gene are more likely to live to advanced age and are partly protected against Alzheimer's disease, but scientists have struggled to explain why.
