Apps for Cognitive Stimulation

There are many apps that are now available that can be used to provide cognitive stimulation. This development is a real game-changer in the brain health industry. Almost anyone with access to a tablet or a smartphone can now download high quality brain exercise and cognitive stimulation apps. In November, 2013 I gave a presentation on this topic at the International Council of Active Aging’s Annual Conference in San Diego, CA. You can download the ICAA Powerpoint File I used in the presentation (contains slides used in classes to teach people how to use the apps) or the pdf version of the presentation.

Here are the cognitive stimulation apps I recommend:

1. Fit Brains
2. Lumosity
3. Tetris
4. Sudoku2
5. Memory Block (like the electronic game Simon)
6. Stroop Effect
7. Visual Attention
8. Brain Lab
9. Word Search+
10. Word Jigsaw
11. Brain Challenge
12. Chain of Thought
13. This is to That
14. Watch That!
16. Peak
17. 1010!
18. Elevate
19. Free Flow
20. Rush Hour
21. Unlock Me
Do you know of any apps that would be appropriate for brain or cognitive exercise? If so, please share them here.

Crossword Puzzles Are Not as Good As Sudoku Puzzles for Exercising the Brain

Crossword Puzzles Are Not as Good As Sudoku Puzzles for Exercising the Brain

By Dr. Rob Winningham


Crossword puzzles, one of the most commonly recognized cognitive stimulation activities, are not actually helping people maximize their memory and attention abilities very much (of course they are not hurting either). Many people are surprised by the assertion that crossword puzzles are not beneficial in preventing age related memory changes. What cognitive abilities are primarily involved when people do crossword puzzles? Crossword puzzles involve getting a cue and then attempting to retrieve previously learned information, which is something that people with age related cognitive impairment and even early to mid stage dementia can do fairly well. Age related changes in cognition and earlier stages of dementia are primarily associated with impairments in the ability to concentrate, pay attention, and make new memories; crossword puzzles don’t really exercise those abilities, but Sudoku puzzles do.


Sudoku puzzles exercise attention and concentration and research shows that exercising those abilities are the most likely to generalize or transfer to the things middle age and older adults need to do in order to maximize their ability to make new memories.

So how do you do Sudokus? There are really only three rules, you need to have each number 1 through 9 in every horizontal row, every vertical column, and sub square on 9 cells. Books of Sudoku puzzles are ubiquitous and can easily be found. And, I recommend for free downloadable Sudoku puzzles. However, 9 X 9 puzzles can be challenging for some people to learn, especially if  they are already experiencing some cognitive impairment.

We have developed a set of easier Sudoku puzzles designed to teach people how to do Sudoku and provide an easier alternative that might be more appropriate for some people (including children). 4_4Start with the easy 4 X 4, then go to the difficult 4 X 4, then easy 6 X 6, followed by harder 6 X 6. Then, the individual should be ready for an easier 9 X 9 puzzle. Note that “easy 9 X 9 Sudoku” is somewhat of a misnomer and they can be made even easier by writing in some of the correct numbers.

Thousands of 9 X 9 Sudoku Puzzles

If you want to make a 9 X 9 sudoku puzzle work your brain even harder then try to do the appropriate level of Sudoku as fast as you can two times. Then, try to do the same level of puzzle while the television news is on. It will be difficult to inhibit paying attention to the television and you can monitor how well you are doing. For example, if someone has the same time to complete the puzzle with and without the television on then they are excellent at inhibiting their attention to irrelevant stimuli.

Many people find the assertion that crossword puzzles are not as effective as Sudoku when trying to improve core cognitive abilities hard to believe. But recent research supports this assertion.  Click here to view the 2013 study.


Maximizing Memory Ability in Older Adulthood


Maximizing Memory Ability in Older Adulthood

Dr. Rob Winningham

Maximizing one’s memory ability in middle and older adulthood requires a multifaceted approach. This short article summarizes recent research showing how we can maximize our memory ability. Any one suggestion won’t have a huge impact, but all together they could have a very significant effect on not only your memory ability but also your quality of life.

It turns out that about 50% of our memory ability and our chance of developing dementia is determined by genetics. So, I hope you chose your parents well, as there isn’t much we can do about our genetic make-up. But the good news is that we can largely control the other 50% that is not genetic.

If you want to maximize your memory ability in adulthood, research shows we need to engage in the following behaviors:

  1. exerciseGet adequate physical exercise. This includes aerobic activity such as walking and other activities that increase heart rate. This also includes strength or resistance training, such as lifting weights. The effects of resistance training are just now being understood, with a 2012 study showing it could lead to significant improvement in attention and concentration for people who are experiencing mild cognitive and memory problems.
  2. Get adequate cognitive exercise. We have all heard of the concept “use it or lose it,” and there is a lot of research that supports this idea. We should never stop learning and challenging ourselves. Cognitive stimulation comes in many forms: we can volunteer, fully engage our hobbies, travel, learn new skills, and engage in targeted cognitive activities. There are even some excellent websites and apps that can help people get targeted brain exercise.
  3. Watch weight, diet, and glucose levels. Controlling weight, avoiding diabetes, and eating right could dramatically reduce the chance of having cognitive problems. There is some evidence that eating fish or a fish oil supplement can reduce one’s chance of developing dementia.Social_Food
  4. Stay socially engaged. Social engagement is very cognitively stimulating and is associated with a reduced likelihood of developing dementia.
  5. Sleep well. Poor sleep quality and quantity can impair brain function and result in a number of physical and mental problems.

In subsequent articles, I will explore the above five factors in more detail.
