The CDC states, "Dementia is not a specific disease but is rather a general term for the impaired ability to remember, think, or make decisions that interferes with doing everyday activities. Alzheimer's disease is the most common type of dementia. Though dementia mostly affects older adults, it is not a part of normal aging."

While it does generally affect people 65 and older, early onset of dementia can start in your 30s, 40s and 50s. 

The CDC's website states additional risk factors. 

  • "Age
    The strongest known risk factor for dementia is increasing age, with most cases affecting those of 65 years and older
  • Family history
    Those who have parents or siblings with dementia are more likely to develop dementia themselves.
  • Race/ethnicity
    Older African Americans are twice more likely to have dementia than whites. Hispanics 1.5 times more likely to have dementia than whites.
  • Poor heart health
    High blood pressure, high cholesterol, and smoking increase the risk of dementia if not treated properly
  • Traumatic brain injury
    Head injuries can increase the risk of dementia, especially if they are severe or occur repeatedly."

    One of the best things to do if you're diagnosed with dementia is to keep your mind active and stay busy, maintain a healthy diet and get plenty of sleep. 

    "Treatment of dementia depends on the underlying cause. Neurodegenerative dementias, like Alzheimer's disease, have no cure, though there are medications that can help protect the brain or manage symptoms such as anxiety or behavior changes. Research to develop more treatment options is ongoing," the CDC says. "Leading a healthy lifestyle, including regular exercise, healthy eating, and maintaining social contacts, decreases chances of developing chronic diseases and may reduce the number of people with dementia."
