What is the most common cause of dementia in older people?
Alzheimer’s disease is the most common cause of dementia in older adults. Other dementias include Lewy body dementia, frontotemporal disorders, and vascular dementia. It is common for people to have mixed dementia—a combination of two or more types of dementia.

Be empowered to discuss memory problems
More than half of people with memory loss have not talked to their healthcare provider, but that doesn’t have to be you. Get comfortable with starting a dialogue with your medical provider if you observe any changes in memory or an increase in confusion, or just if you have any questions. You can also discuss health care planning, management of chronic conditions, and caregiving needs.
Risk reduction and a healthy brain
There currently is no cure for dementia, however, there are medications to help with the symptoms. Here are some steps you can take to reduce your risk:
• Chronic disease prevention:
o If you are a smoker, stop smoking.
o Maintain a healthy blood pressure level.
o Manage cholesterol levels with exercise and, if needed, cholesterol medications.
o Keep blood sugar within a healthy range.
o Get to and maintain a healthy weight.
o If you drink alcohol, do so in moderation‒up to one drink per day for women and up to two drinks per day for men.
• Reduce hazards in your environment that could lead to falls or head injury.
• Healthy living:
o Eat whole foods with plenty of nutrients and vitamins.
o Exercise, including aerobic physical activity.
o Get good quality sleep.
• Keep your mind active and stimulated, with challenging tasks such as learning a new activity.
• Maintain social contacts.
