Jennifer PrescottRN, MSN, CDP and founder of Blue Water Home Care and Hospice shares, “Dementia is a common term that describes a group of symptoms that affect memory, decision-making, and reasoning. The most common form of dementia is Alzheimer’s disease which, according to Alzheimer’s Association Facts and Figures Report 2022 approximately 6.5 million Americans age 65 and older have Alzheimer’s dementia.

Prescott says:Certain lifestyle choices can increase your risk of developing dementia or Alzheimer’s disease. More studies continue to be conducted to see a direct correlation between habits and the prevalence of Alzheimer’s disease.

These risk factors/habits may include:

  • Advanced age
  • Family history of Alzheimer’s disease or dementia
  • Race/ethnicity – The CDC reports that older African Americans are twice as likely to have dementia as Caucasians. Hispanics are 1.5 times more likely to have dementia than Caucasians.
  • Inactivity or lack of exercise
  • Lack of brain stimulation
  • Smoking
  • High blood pressure – high blood pressure can increase the risk of certain types of dementia. More research needs to be done to determine if lowering blood pressure reduces the risk of dementia.
  • High cholesterol – may increase risk of dementia if left untreated
  • traumatic brain injury”

Every week, adults need 150 minutes of moderate-intensity physical activity and 2 days of muscle-strengthening activity, depending on the current situation.
