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.

California looked to them to close health disparities, then it backpedaled

Fortina Hernández is called "the one who knows it all." For more than two decades, the community health worker has supported hundreds of families throughout southeast Los Angeles by helping them sign up for food assistance, sharing information about affordable health coverage, and managing medications for their chronic illnesses.

Experts say you don’t need 10,000 steps, here’s the new magic number

A major systematic review finds that walking just 7,000 steps per day, rather than the traditional 10,000, can significantly reduce the risk of mortality, cardiovascular disease, dementia, and more. The analysis, published in The Lancet Public Health, provides an evidence-based and achievable target for adult health.

Walking 7,000 steps per day associated with reductions in risk of several serious health problems

A comprehensive new study analyzing data from over 160,000 adults finds that walking approximately 7,000 steps per day is associated with reductions in the risk of several serious health outcomes, including all-cause mortality (47% reduction), cardiovascular disease (25% reduction), cancer (6% reduction), type 2 diabetes (14% reduction), dementia (38% reduction), depression (22% reduction), and falls (28% reduction).

Study reveals pandemic life made brains age faster, even without catching COVID-19

The COVID-19 pandemic accelerated biological brain aging in older adults by an average of 5.5 months over less than three years, regardless of infection status. Social disruption, age, male sex, and socioeconomic disadvantage heightened vulnerability, while only infected individuals showed measurable declines in executive function.
