Most blood tests to detect Alzheimer’s disease perform inconsistently across racial groups

Three experimental blood tests used to identify people in early stages of Alzheimer's disease perform differently in Black individuals compared to white individuals, according to a new study from Washington University School of Medicine in St. Louis.

People who accumulate cardiovascular risk factors quickly have higher risk of developing dementia

Cardiovascular disease risk factors, like high blood pressure, diabetes, obesity and smoking, are believed to play key roles in the likelihood of developing cognitive decline, dementia, and Alzheimer's disease.

New research takes a close look at the most prevalent neurotransmitter in the brain

One of the most important molecules in the brain doesn't work quite the way scientists thought it did, according to new work by researchers at Columbia University Vagelos College of Physicians and Surgeons and Carnegie Mellon University.

Advancements in HIV science

As far as viruses go, human immunodeficiency virus (HIV) is quite simple. About 100,000 times smaller than a red blood cell, the virus expresses just a dozen proteins, yet it can establish a lifelong infection that, if left untreated, causes acquired immunodeficiency syndrome (AIDS) and death.

Researchers discover more needles in the haystack in the quest to unravel Alzheimer’s disease

21 million. That's the number of genetic variations in the human genome that researchers are sifting to identify patterns predisposing people to Alzheimer's disease.

Single-cell genome sequencing provides a new way to think about Alzheimer’s disease

Alzheimer's disease is marked by a loss of functional neurons in the brain. But what causes this loss? Through single-cell genome sequencing, researchers at Boston Children's Hospital, Brigham and Women's Hospital, and the Broad Institute show that people with Alzheimer's have an abundance of newly acquired mutations in their neurons -; more than people of the same age without Alzheimer's, and enough to disable genes important to brain function.

'Epigenetic age' can predict performance on cognitive tests later in life

Epigenetic markers of cognitive aging can predict performance on cognitive tests later in life, according to a study published in the journal Aging.

Einstein Aging Study secures $32 million NIH grant to help address the rising tide of Alzheimer's disease

To help address the rising tide of Alzheimer's disease nationwide, researchers at Albert Einstein College of Medicine in collaboration with faculty at Pennsylvania State University and other institutions, have received a five-year, $32 million grant from the National Institutes of Health to support the ongoing Einstein Aging Study, which focuses on both normal aging and the special challenges of Alzheimer's disease, and other dementias. EAS was established at Einstein in 1980 and has been continuously funded by the NIH.

Little-known protein found to play a role in common neurodegenerative disorder

Scientists have known for years that amyloid fibrils -; fibrous, ropelike structures formed by closely linked protein molecules -; are present in the brains of patients with Alzheimer's and Parkinson's diseases and likely play a role in the progression of these disorders.

Five different diseases attack language areas in the brain that cause primary progressive aphasia

There are five different diseases that attack the language areas in the left hemisphere of the brain that slowly cause progressive impairments of language known as primary progressive aphasia (PPA), reports a new Northwestern Medicine study.

Type I interferon found to be major driver of memory, cognitive loss in Alzheimer's disease mouse model

Alzheimer's disease (AD), the most common type of dementia, progressively impairs memory, concentration and the ability to learn new things and accomplish everyday activities.

Levels of little-studied enzyme found to decline with age and more dramatically with Alzheimer’s

A little-studied enzyme has been found in high levels in healthy neurons, levels that scientists say decline with age and more dramatically with Alzheimer's, making adjusting the enzyme's level a potential treatment for both.

Study finds higher risk of dementia among patients hospitalized with COVID-19 pneumonia

A new study from the from the University of Missouri School of Medicine and MU Health Care shows patients hospitalized with COVID-19 pneumonia have a higher risk of developing dementia than those with other types of pneumonia.

New insight into neuropsychiatric symptoms in people with Alzheimer’s disease

In addition to memory problems and other cognitive symptoms, most people with Alzheimer's disease also suffer from mental health issues.

Washington state retools first-in-the-nation long-term care benefit

Patricia Keys, 71 and a stroke survivor, needs help with many everyday activities, such as dressing and bathing. Her daughter Christina, who lives near her mom in Vancouver, Washington, cares for her in the evenings and pays about $3,000 a month for help from other caregivers.

Inhibiting key signaling pathway in immune cells may slow down Alzheimer's disease

Inhibiting an important signaling pathway in brain-resident immune cells may calm brain inflammation and thereby slow the disease process in Alzheimer's and some other neurodegenerative diseases, suggests a study by Weill Cornell Medicine investigators.

Chronic tiredness in people with sleep apnea can have serious implications for road safety

Up to half of older adults may have sleep apnea, a condition in which breathing and sleep are briefly interrupted many times a night.

Healthy lifestyle may reduce the risk of dementia and extend life expectancy

A US study published by The BMJ today suggests that a healthy lifestyle is associated with a longer life expectancy among both men and women, and they lived a larger proportion of their remaining years without Alzheimer's disease.

Exercise maintains insulin and body mass index levels to help protect brain volume

Studies have shown that exercise helps protect brain cells. A new study looking at the mechanisms involved in this relationship suggests that the role exercise plays in maintaining insulin and body mass index levels may help protect brain volume and thus help stave off dementia.

Report: Depression and loneliness have increased among older adults during COVID-19 pandemic

Rates of depression and loneliness have increased among older adults during the COVID-19 pandemic, prompting a need for more coordinated efforts to address the issue going forward, according to a new report on social isolation among older Canadians.
