Elevated tau in Long COVID patients raises risk for neurodegenerative diseases

A study of 227 individuals who experienced neuro cognitive difficulties post COVID-19 infection – such as headaches, vertigo, balance dysregulation, changes in taste/smell, and brain fog – displayed a significant increase in their blood plasma of a crucial protein called tau, which is found in nerves and especially in the brain.

Super agers' resilience against Alzheimer's disease linked to protective gene variant

The gene variant posing the greatest genetic risk of late-onset Alzheimer's disease (AD) is called APOE-ε4. A different variant of the same gene, APOE-ε2, is thought to confer protection against AD.

Study reveals how ketogenic diet protects against epilepsy seizures

University of Virginia School of Medicine researchers have revealed how the popular, low-carb ketogenic diet protects against epilepsy seizures and possibly neurodegenerative diseases such as Alzheimer's and Parkinson's.

Majority of older adults in Ireland have poorly controlled high blood pressure

High blood pressure becomes more common after age 40years yet new research from The Irish Longitudinal Study on Ageing (TILDA) at Trinity College Dublin shows that many people in Ireland with hypertension are still not optimally diagnosed or treated based on European Gudelines.

Study finds growing long-term antipsychotic prescribing in elderly dementia patients

When agitated dementia patients wander or shout through the night, families and caregivers understandably feel the need to treat this frightening and potentially dangerous behavior. Antipsychotic medications are often resorted to with such patients, contributing to increases in antipsychotic treatment rates among older people.

Experts issue strong call for overhaul of UK dementia prevention strategy

A national panel of experts has issued the strongest call yet for the Department of Health and Social Care to overhaul how it approaches dementia prevention, pointing to vital evidence that dementia risk can be reduced and providing a framework for the development of new government policy that could improve brain health for millions.

Kaiser Permanente to pay $556 million in record Medicare Advantage fraud settlement

In the largest Medicare Advantage fraud settlement to date, Kaiser Permanente has agreed to pay $556 million to settle Justice Department allegations that it billed the government for medical conditions patients didn't have.

New blood biomarker tracks brain injury progression after ischemic stroke

A new blood marker reflects the extent of brain injury after an ischemic stroke and can predict patient outcomes months to years later.

Incretin-based diabetes drugs show potential protective effects against dementia

A large McGill University study has found that two classes of medications commonly prescribed for Type 2 diabetes, both incretin-based, are associated with a reduced risk of dementia.

Autonomous AI system screens for cognitive impairment using routine clinical notes

A team of Mass General Brigham researchers has developed one of the first fully autonomous artificial intelligence (AI) systems capable of screening for cognitive impairment using routine clinical documentation.

Repurposed Alzheimer’s medication offers low-cost hope for sickle cell anemia

Sickle cell anemia is the world's most common genetic disorder. It causes the red blood pigment hemoglobin to crystallize, which results in rigid, malformed red blood cells with a sickle shape.

MIT researchers map dynamic fuzzy coat surrounding tau protein fibrils

One of the hallmarks of Alzheimer's disease is the clumping of proteins called Tau, which form tangled fibrils in the brain. The more severe the clumping, the more advanced the disease is.

Hearing aid use has little impact on cognitive test scores

A new study has found that for people with moderate hearing loss, being prescribed hearing aids had little impact on cognitive test scores.

Post-meal blood sugar spikes linked to increased Alzheimer's risk

A new study led by researchers from the University of Liverpool has found that spikes in blood sugar after meals may increase the risk of Alzheimer's disease.

Vaccines are helping older people more than we knew

Let's be clear: The primary reason to be vaccinated against shingles is that two shots provide at least 90% protection against a painful, blistering disease that a third of Americans will suffer in their lifetimes, one that can cause lingering nerve pain and other nasty long-term consequences.

New European initiative aims to transform real world Alzheimer’s disease care

Today, the ACCESS-AD consortium is announcing the launch of a transformative European initiative that will accelerate the implementation of scientific innovations for Alzheimer's disease (AD) management in real-world health systems.

Study explores how biological and environmental systems regulate body weight

Pennington Biomedical researchers recently investigated the systems of the body that regulate weight, exploring whether our bodies defend an established weight target or if our bodies operate within a broader range of tolerance before biological mechanisms are activated.

Study sheds new light on how structural brain changes are tied to memory decline in aging

A landmark international study that pooled brain scans and memory tests from thousands of adults has shed new light on how structural brain changes are tied to memory decline as people age.

Single-cell analysis reveals gene disruptions in early-onset Alzheimer's brain regions

A new study led by researchers at UTHealth Houston investigated both gene expression and regulation at single cell levels to reveal disruptions in gene function in three brain regions of patients with sporadic early onset Alzheimer's disease.

Research finds persistent prescribing of risky medications to older adults with dementia

Despite years of clinical guidelines warning against the practice, one in four Medicare beneficiaries with dementia is prescribed brain-altering medications linked to falls, confusion, and hospitalization, according to new research to be published January 12 in the peer-reviewed journal JAMA.
