Can stress and anxiety cause dementia?

Researchers found that chronic stress is a significant risk factor for dementia. Because this study looked at several previous studies, its findings are particularly convincing. A study of 1,700 seniors with an average age of 77 found a link between depression—which can both cause and be caused by stress—and dementia.

What does early dementia look like?

Apathy, or listlessness, is a common sign in early dementia. A person with dementia may lose interest in hobbies or activities that they used to enjoy doing. They may not want to go out anymore or have fun. They may also lose interest in spending time with friends and family, and they may seem emotionally flat.

Can a person recover from dementia?

There is currently no "cure" for dementia. In fact, because dementia is caused by different diseases it is unlikely that there will be a single cure for dementia. Research is aimed at finding cures for dementia-causing diseases, such as Alzheimer's disease, frontotemporal dementia and dementia with Lewy bodies.

Do people with dementia sleep a lot?

It is quite common for a person with dementia, especially in the later stages, to spend a lot of their time sleeping – both during the day and night. This can sometimes be distressing for the person's family and friends, as they may worry that something is wrong.

Is dementia more common in males or females?

Worldwide, women with dementia outnumber men 2 to 1. Brain scans tell us that the rate at which brain cells are dying in the brain is faster in women than in men. Women are more likely to live longer than men. However, although risk increases with age, dementia is caused by diseases of the brain not age alone.

How likely am I to get dementia if my mom has it?

Studies of family history say that if you have a close relative who has been diagnosed with Alzheimer's disease—the most common form of dementia in older adults—your risk increases by about 30%.
