Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

Frequent TV watching may harm long-term brain health

"Turn off that TV, it'll rot your brain!" has been a household refrain for decades. While "rot" might be too strong a term, researchers are finding that the overall sentiment could have some merit.

Tau buildup in progressive supranuclear palsy alters brain networks linked to thinking and behavior

Researchers at Japan's National Institutes for Quantum Science and Technology (QST) have found that tau buildup in progressive supranuclear palsy (PSP) may affect brain networks involved in thinking and behavior.

SORLA protein may protect the brain from toxic tau tangles

Alzheimer's disease and many other forms of neurodegeneration share a common culprit. In these diseases, tau proteins that normally stabilize neuronal microtubule filaments within our nervous system networks instead form noxious knots and gradually disrupt the circuits they would otherwise preserve.

Study urges Japan to rethink universal healthcare by 2040

On July 16, 2026, an international research team led by Tohoku University published two policy review papers that examine Japan's health system and global health strategy in The Lancet Regional Health - Western Pacific - the Lancet group's first Japan-focused feature in about 15 years.

A wife’s account reveals the hidden burden of young-onset Alzheimer’s caregiving

Karina Acton Reid recounts caring for her husband with young-onset Alzheimer’s disease presenting as posterior cortical atrophy while raising two young children. Her perspective shows how visual disorientation, diagnostic delays, changing family roles, and inadequate age-appropriate support affect the entire household.

Blood p-tau217 levels signal cognitive impairment risk years before symptoms emerge

Higher baseline plasma p-tau217 was associated with greater 5- and 10-year risks of cognitive impairment and faster cognitive decline among 2,684 cognitively unimpaired adults. Very high levels corresponded to an estimated 38% risk at five years, but selected cohorts and limited long-term data mean routine screening and individualized prediction remain premature.

Researchers identify new genetic pathway driving epilepsy and seizures

Researchers have uncovered a novel biological pathway that can lead to seizures when disrupted. The findings also provide a new approach to improve the diagnosis of epilepsy, for which a genetic cause cannot be found in about 50 % of individuals with the condition

WHO updates guidelines to reduce risk of dementia worldwide

The World Health Organization (WHO) today released updated guidelines on reducing the risk of cognitive decline and dementia, providing countries with evidence-based recommendations to help prevent or delay the onset of dementia across the life course.

Sleeping longer may signal early Alzheimer's-related brain changes

Regularly sleeping long hours each night is associated with higher levels of an Alzheimer's-related protein in the blood, even accounting for other health factors, suggests a new study from UT Health San Antonio, the academic health center of The University of Texas at San Antonio.

Brain’s immune cells play key role in maintaining stability of neuronal networks in Alzheimer's disease

Researchers at Trinity College Dublin have discovered that microglia – the main immune cells of the brain – play a critical role in maintaining the stability of neuronal networks in Alzheimer's disease.

Self-assembling antibody drugs successfully target multiple cancer receptors

Modern anticancer medications that combine tumor-fighting drugs with proteins that specifically target cancer cells are a relatively new class of drug, often given to patients for whom standard chemotherapy has not worked.

Study sheds light on the prognostic value of blood test for predicting cognitive impairment risk

A blood test for the biomarker phosphorylated tau 217 (p-tau217) recently received federal clearance, but questions have emerged around the extent to which such tests can accurately predict whether a cognitively healthy individual will go on to develop cognitive impairment-a key symptom of Alzheimer's disease.
