How to Keep Your Mind Sharp to Help Prevent Dementia 

Health & Aging

Alzheimer's disease is the sixth leading cause of death in the United States. The disease affects 43 percent of people ages 75 to 84. Over 800,000 Americans are estimated to be living with Alzheimer's, and women are more likely to develop the disease than men.

Dementia is a scary topic, and a growing concern for many people. The best way to avoid experiencing the effects of dementia is to take as many steps as possible to keep your brain sharp and exercise your neural connections on a daily basis. We have compiled a comprehensive list of ways to exercise your mind and keep yourself sharp below.

Physical Games

One way to actively practice sharpening your brain is to complete puzzles on a weekly, or even daily basis. Puzzles offer cognitive training that improve multiple areas of the brain such as memory, reasoning and speed processing. These brain activities produce a cognitive reserve that could potentially delay clinical onset dementia by years. Some puzzles that are great for training the brain are:
  • Crosswords
  • Word searches
  • Sudokus
  • Riddles 
  • Picture comparison games (find the difference)
  • Rubix cubes
  • Jigsaw puzzles
  • Sliding puzzles
By participating in these sorts of games you are practicing recall abilities and working different nerves within the brain to help keep them healthy.


  • Lumosity
    • Lumosity is a brain training app with over 40 games and activities that challenge five core cognitive abilities. The app offers insights on your strengths, weaknesses and cognitive patterns.

      In addition to brain games, the app has the option to participate in mindfulness practices, an exercise that improves source memory. Lumosity has a free and premium version available.

      The premium version costs $11.99 for a month or $59.99 for a year and unlocks all games and activities in the app. There is also a desktop version of Lumosity available for those who prefer to use a desktop rather than a portable smart device.

Learn something new
  • Second language
    • The American Academy of Neurology found that people who are able to speak two or more languages are less likely to develop memory problems than those who only speak one language. It has been proven that bilingual people developed dementia 4.5 years later than monolingual people.

      Learning languages increases both the language centers of the brain and the hippocampus, an area of the brain that is often one of the first affected by dementia. Learning languages also increases neural pathways and increases blood flow in the brain, both of which combat against dementia.

      There are many resources available to aid in learning a new language, which range from local classes to online learning programs such as Rosetta Stone

  • Adult classes

Diet and Exercise 

According the the Alzheimer's Association, diet and exercise are an important part of improving overall health and preventing dementia. The cardiovascular benefits of exercise can significantly improve brain function by providing more blood and oxygen to brain cells.

Additionally, exercise increases the level of brain chemicals called growth factors, which help generate new brain cells and establish new connections between brain cells—aiding in the learning process. For those looking for an even bigger brain boost, complicated activities like playing tennis or taking a dance class provide even more mental stimulation.

Exercise appears to protect the hippocampus, which governs memory and spatial navigation, and is one of the first brain regions to succumb to Alzheimer's-related damage. Even mild activity like a leisurely walk can help keep your brain fit and active—fending off memory loss and keeping skills like vocabulary retrieval strong.

Another important aspect of keeping your brain sharp is to maintain a healthy diet. The Alzheimers Association recommends two types of diets: the DASH (Dietary Approaches to Stop Hypertension) diet and the Mediterranean diet. 

  • DASH diet
    • Vegetables and fruits
    • Fat-free dairy products
    • Whole grains
    • Fish and poultry
    • Beans
    • Seeds
    • Nuts
    • Vegetable oils
    • Limit sodium, sweets, sugary drinks and red meats
  • Mediterranean diet
    • Whole grains
    • Fruits and vegetables
    • Fish and shellfish
    • Nuts
    • Olive oil and other healthy fats
    • Limited red meat
