Alzheimer's Disease News and Research

RSS

Alzheimer's disease (AD) is an irreversible, progressive brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living. In most people with AD, symptoms first appear after age 60. AD is the most common cause of dementia among older people, but it is not a normal part of aging. Dementia refers to a decline in cognitive function that interferes with daily life and activities. AD starts in a region of the brain that affects recent memory, then gradually spreads to other parts of the brain. Although treatment can slow the progression of AD and help manage its symptoms in some people, currently there is no cure for this devastating disease.

People with higher blood DHA levels are 49% less likely to develop Alzheimer's disease, study shows

New research published today in Nutrients shows that people with a higher blood DHA level are 49% less likely to develop Alzheimer's disease vs. those with lower levels, according to the Fatty Acid Research Institute (FARI).

Association of neuronal and non-neuronal GABA with neuropsychiatric illness in COVID-19 patients

A new study published in the journal Reports focused on the hijacking of the pancreatic, endothelial, and gut GABA by SARS-CoV-2 and its associated pathology along with interventions.

Shingles is not associated with increased risk of dementia, finds study

Shingles, a viral infection caused by the reactivation of the chickenpox virus, results in a painful blistering rash along one side of the body or face from nerve inflammation. There has been scientific speculation that such inflammation may increase a person's risk of dementia.

Multiple heart-related conditions may increase dementia risk to a greater extent than genetics

Having multiple conditions that affect the heart are linked to a greater risk of dementia than having high genetic risk, according to a largescale new study.

Social isolation may be an early indicator of increased dementia risk

Social isolation is linked to lower brain volume in areas related to cognition and a higher risk of dementia, according to research published in the June 8, 2022, online issue of Neurology, the medical journal of the American Academy of Neurology.

USC scientists receive more than $16 million to study the role of blood vessel dysfunction in Alzheimer’s disease

The National Institute on Aging, a division of the National Institutes of Health, awarded Berislav Zlokovic, MD, PhD, director of the Zilkha Neurogenetic Institute, and Arthur W. Toga, PhD, director of the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI), $16.1 million to continue research on the role that blood vessel dysfunction plays in the development of dementia and Alzheimer's disease.

Oral administration of rapamycin increases β-amyloid buildup in Alzheimer's disease mouse model

Researchers from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) have found that oral administration of rapamycin to an Alzheimer's disease mouse model causes an increase in beta (β)-amyloid protein plaques. β-amyloid buildup is a hallmark of Alzheimer's disease.

Age exacerbates COVID neuroimmunological symptoms

In a recent study posted to the bioRxiv* pre-print server, researchers at the University of Illinois at Chicago investigated whether aging exacerbated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection-induced neuropsychiatric disorders.

Diabetes drug's target protein can be a candidate for the treatment of Alzheimer's disease

Mechanisms associated with a particular diabetes drug can also help to protect against Alzheimer's disease, a study by researchers at Karolinska Institutet in Sweden and published in Neurology reports.

Truncated tau protein may be a means for better diagnosis and treatment of Alzheimer's disease

In a new study of Alzheimer's disease, researchers at UC San Francisco have discovered that a relatively unstudied form of the tau protein associated with neurodegeneration may be a means for better diagnosis and treatment of the disease.

New study in mice shows alternate origins of plaques in Alzheimer’s disease

A breakdown in how brain cells rid themselves of waste precedes the buildup of debris-filled plaques known to occur in Alzheimer's disease, a new study in mice shows.

New SOL-INCA-AD grant extends the initial study to examine cognitive aging among Latinos

Researchers at University of California San Diego School of Medicine have received a $24.5 million grant from the National Institutes of Health (NIH)/National Institute on Aging (NIA) to continue the Study of Latinos-Investigation of Neurocognitive Aging (SOL-INCA), a 12-year assessment of cognitive and brain aging and impairment among aging Latinos.

Stem cell model could provide insights into biological mechanisms that underlie neuropsychiatric disorders

Researchers from the Icahn School of Medicine at Mount Sinai have applied a novel stem cell model to map disease risk variants in human neurons, which could help provide insights into the biological mechanisms that underlie neuropsychiatric disorders such as autism and schizophrenia.

Ultrasound localization microscopy can image microscopic vessels and measure blood flow in the brain

To image microscopic vessels and measure blood flow in the brain, researchers use a tool called ultrasound localization microscopy. It works by using microscopic bubbles circulated through the bloodstream as a contrast agent to measure the reflection of high-frequency acoustic waves passing through the body.

Dementia diagnosis can also make a big difference in health care costs

Getting diagnosed with Alzheimer's disease or another kind of dementia is never pleasant – but a new study shows that when and how someone's cognitive issues come to light can also make a big difference in their health care costs.

Physicians should have rudimentary knowledge of the benefits of plant-based diet for six health conditions

A new commentary in the American Journal of Lifestyle Medicine says that all physicians should be aware of the benefits of a plant-based diet for six health conditions: weight loss and maintenance, cardiovascular disease, cancer, diabetes, Alzheimer's disease, and COVID-19.
