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.

Ageing slows brain protein clearance and shifts synaptic waste to microglia

Ageing slows neuronal protein degradation in mice, leading to widespread accumulation and aggregation of long-lived proteins, particularly at synapses. As neuronal clearance declines, microglia selectively accumulate synaptic proteins, suggesting a compensatory but potentially strained proteostasis pathway in the ageing brain.

Nearly half of adults now live with heart disease as obesity and diabetes surge

The 2026 American Heart Association Heart Disease and Stroke Statistics report shows that nearly half of adults are living with cardiovascular disease, with cardiometabolic risk factors projected to rise substantially by 2050. Despite progress in smoking reduction and cholesterol control, worsening obesity, diabetes, hypertension, sleep health, and persistent inequities threaten future cardiovascular health.

Brain complexity declines in Alzheimer's disease

As individuals with Alzheimer's disease (AD) move from the mild cognitive impairment stage to moderate and severe dementia, complex awareness deteriorates although lower-level sensory awareness is relatively maintained.

High BMI linked to vascular dementia risk

High body mass index (BMI) could cause a higher risk of vascular-related dementia (a combination of vascular + unspecified dementia), according to new research from the University of Bristol and University Hospital of Copenhagen (Rigshospitalet and Herlev-Gentofte hospital).

Regular aerobic exercise slows a key marker of brain aging in midlife

Regular aerobic activity significantly reduces brain-PAD, indicating that exercise is crucial for maintaining brain health and reducing dementia risk.

Lifelong health: The Northern Finland Birth Cohort 1966 enters a new era of aging research

One of the world’s most extensive birth cohorts is now entering later adulthood. At the University of Oulu in Finland, the Northern Finland Birth Cohort 1966 (NFBC1966) is launching a major new follow-up combining decades of biological, social, and environmental data with modern digital health tools to examine how lifelong exposures and the genome shape health and aging.

Red light therapy may protect athletes' brains from repetitive impacts

Punch-drunk syndrome, boxer's madness, chronic traumatic encephalopathy (CTE). The name has changed over the years, but the cause is clear: repeated impacts can affect long-term brain health, with symptoms ranging from confusion to memory loss and potentially dementia.

Pandemic linked to lasting drops in diagnosis rates for major conditions

There has been a lasting and disproportionate impact of the Covid-19 pandemic on diagnosis rates for conditions including depression, asthma and osteoporosis.

Long-term air pollution exposure raises motor neuron disease risk

Long-term exposure to ambient air pollution was associated with a higher risk of developing motor neuron disease and poorer prognosis after diagnosis in a large nationwide Swedish study. Higher particulate matter and nitrogen dioxide exposure were also linked to faster functional decline and increased likelihood of invasive ventilation.

Shingles vaccination is linked to slower biological aging in older adults

This population-based study of U.S. adults aged 70 and older found that shingles vaccination was associated with slower epigenetic and transcriptomic aging, as well as lower systemic inflammation. No significant associations were observed for neurodegeneration or cardiovascular biomarkers, highlighting domain-specific molecular effects rather than broad clinical changes.

Exercise-triggered mitochondrial transfer offers hope for stroke and dementia

Physical rehabilitation and symptom management still remain the mainstay of treatment for stroke, as clot removal or dissolution is effective only within a narrow time frame after the stroke.

The neuroscience of motivation-driven memory retention

Researchers from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), and Duke University have proposed a neuroscience framework explaining how different types of motivation fundamentally reshape what and how the brain remembers.

Tracing the decline in American heart disease mortality

Following a five-year upward trend likely impacted by the COVID pandemic, the number of heart disease and stroke deaths has declined, yet, heart disease and stroke still kill more people in the U.S. each year than any other cause, according to data reported in the 2026 Heart Disease and Stroke Statistics: A Report of U.S. and Global Data From the American Heart Association.

Shingles vaccination may slow biological aging in older adults

Shingles vaccination not only protects against the disease but may also contribute to slower biological aging in older adults, according to a new USC Leonard Davis School of Gerontology study.

Adding lean pork to a plant-forward diet supports healthy aging biomarkers

A randomized crossover feeding trial in adults aged 65 years or older found that plant-forward diets incorporating either minimally processed lean pork or lentils produced similar short-term improvements in cardiometabolic and neuroactive biomarkers. Both diets supported metabolic health and functional stability, with no overall adverse biomarker effects attributable to including minimally processed red meat within a Dietary Guidelines–aligned pattern.

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.

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.
