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.

Plasma proteins offer clues to biological aging and mortality risk

A new study published in Geromedicine has identified 17 plasma proteins associated with all-cause mortality in older adults and found that several of these proteins also track with measures of biological aging across multiple organ systems.

Diverse social activities may help slow age-related cognitive decline

Diverse and sustained social activities may boost cognitive performance and slow the decline in brain health associated with aging, suggest the findings of a large international study, published online in the Journal of Epidemiology & Community Health.

Rice, fish and pickles: Is the traditional Japanese diet as healthy as we think?

A systematic review of 37 studies found that greater adherence to predefined Japanese-style dietary patterns was associated with lower all-cause and cardiovascular mortality, based on pooled evidence from three cohort studies. However, health associations varied according to dietary composition, suggesting that traditional Japanese diet scores alone may not adequately distinguish the potential benefits and risks of different food combinations.

Study links abnormal immature astroglia to lower fluid intelligence in older epilepsy patients

A new USC-led study links abnormal immature astroglia, star-shaped cells that support brain function, to lower fluid intelligence, or the ability to solve new problems, in older adults with epilepsy.

Miro1 protein linked to insulin resistance in type 2 diabetes

A protein called Miro1 found at elevated levels in the skeletal muscle of people with Type 2 diabetes may contribute to insulin resistance, potentially making it a target for future treatments that help the body regulate blood sugar, according to a study published today in Nature Communications.

Epilepsy linked to higher risk of young-onset dementia

People with epilepsy may be more likely to develop young-onset dementia than people without epilepsy, according to a study published October 14, 2026, in Neurology®, the medical journal of the American Academy of Neurology.

People who walk more each day tend to score better on several brain tests

Researchers analyzed 14 years of physical activity and blood pressure records from 3,093 US adults and found that higher daily step counts were associated with better performance on tests of attention, cognitive control, and reward-related decision-making. Higher systolic blood pressure was associated with poorer delay-discounting performance, but accounted for only 4.8% of its association with physical activity, while the single cognitive assessment prevented conclusions about causation or cognitive decline.

Women with polyendocrine metabolic ovarian syndrome more likely to have Alzheimer's and dementia

Alzheimer's disease and dementia may be more common in women with polyendocrine metabolic ovarian syndrome (PMOS), formerly known as polycystic ovary syndrome (PCOS), according to a review of existing evidence published in the Journal of the Endocrine Society.

Scientists pinpoint key hotspot driving tau propagation in dementia

Diseases such as Alzheimer's and frontotemporal dementia are considered neurodegenerative tauopathies, in which tau proteins in the brain misfold and lead to cognitive decline.

16-year study links worsening vision to higher dementia risk

Researchers followed 15,576 older adults in Hong Kong for up to 16 years and linked moderate to severe visual impairment to higher dementia risk, with rapid visual decline strengthening the association at poorer levels of vision. They estimated that severe impairment corresponded to 2.1 fewer dementia-free years over the study period, but could not establish that correcting vision prevents dementia.
