A recent study found the number of dementia cases in the United States is expected to double by the year 2060.

“The number of people over the age of 65 is expected to increase consistently over the many decades coming up, and age is the highest risk factor for onset of dementia,” explained Dr. Jagan Pillai, a neurologist at the Cleveland Clinic.

Dr. Pillai was not a part of the study, but said the findings highlight why more research is needed when it comes to prevention and treatment. He also noted the disparities reported among women and Black people.

The study shows they have a higher lifetime risk for dementia.

Dr. Pillai said dementia results from a decline in a person’s memory, reasoning, language, coordination or behavior, and can make it very difficult for someone to take care of themselves.

While age is one of the biggest risk factors for dementia, lifestyle choices like smoking, family history and heart health can also play a role.

Diet and exercise also seem to help stave off the onset of dementia.

“The more physically active you are, that decreases your dementia risk. Healthy eating habits, like the Mediterranean diet, are shown to be effective, along with being socially and cognitively engaged,” he said. “Picking up new skills, being socially active and engaged in the community also seems to staff off the onset of dementia.”

There is currently no cure for dementia. However, there are different treatment options available which can, in some cases, help slow the progression of symptoms.
