The team reviewed dozens of previous studies that considered environmental risk factors linked to dementia. They found that a lack of vitamin D – produced by the body through exposure to sunlight – and exposure to air pollution were implicated, along with occupational exposure to some types of pesticide.
Is dementia genetic or environmental?
In most cases, dementia is not strictly hereditary, but the disease underlying dementia is usually caused by a combination of various genetic and environmental factors. However, there are a few cases of familial dementia, where dementia is inherited and caused by genetic mutations.
Is Alzheimer’s environmental?
Scientists believe that for most people, Alzheimer’s disease is caused by a combination of genetic, lifestyle and environmental factors that affect the brain over time. Less than 1% of the time, Alzheimer’s is caused by specific genetic changes that virtually guarantee a person will develop the disease.
What’s an example of an environmental trigger?
Some common triggers include dust mites and mold, pets, strong odors, cockroaches, cigarette and cigar smoke, viral or sinus infections, emotions, weather changes, pollution, and exercise. (See “Examples of Triggers” for a more extensive list.)
What are environmental factors of Alzheimer’s?
The proposed Alzheimer’s exposome includes macrolevel external factors such as living in rural versus urban areas, exposure to pollution and socioeconomic status, along with individual external factors such as diet, cigarette smoking, exercise and infections.
What are triggers in dementia?

Why do dementia patients clench their fists?
The researchers think clenching a fist activates specific brain regions that are associated with memory processing. Lead scientist Ruth Propper, of Montclair State University, Montclair, New Jersey, said the research suggests simple body movements can improve memory by temporarily changing the way the brain functions.
