Participate in our Memory Exercises Study

Help us discover how peoples' cognitive abilities change according to age and other conditions.

"One has to begin to lose his/her memory, if only in bits and pieces, to realize that memory is what makes our lives. Life without memory is no life at all... Our memory is our coherence, our reason, our feeling, even our action. Without it, we may feel nothing..."

The above moving and frightening quote is from Luis Bunuel, the famous film maker. My  observations of people with different neurological disorders including Alzheimer disease, often makes me wonder what sort of a life, what sort of a self, can be preserved in a human who is losing his/her memory and feeling lost in time. These are questions that nobody has an answer for it. Nevertheless, as Dr. Sacks, says, however great the brain damage might be, there remains the undiminished possibility of reintegration by art, by communion, by touching the human spirit; this can be preserved in what seems at first a hopeless state of neurological devastation. This is also what I've observed in my interactions with patients affected by dementia, Alzheimer, and cerebral palsy.

Aside from the unknown and rare conditions that may cause a neurological dysfunction, there are ways to age with a healthy brain. It is known that our memory weakens by aging. But the good news is that, in general, at any age we can strengthen and sharpen our memory and cognition. Think of the brain like a muscle; if we don't use our muscles actively, they atrophy and shrink. Thus, the general phrase of "use it or loose it" applies to brain's neurons and their connections (synapses) too.

My group has designed a series of experimental memory exercises to strengthen memory, in particular the "associative memory": the memory that is formed based on our experiences every day. We make associations between different objects in order to remember and use them in our daily life. For example, we learn to associate an ATM machine with money. But as we age, we may find learning new concepts and making new associations a bit more difficult. The purpose of  these exercises is to help with learning new concepts.  My recommendation is to play at least two of them (the first two in particular) for about 15-20 minutes in the morning, every day. As a rule of thumb, if you can remember only up to 5 or less random words in  "short term memory" exercise, you may decide to do these exercises regularly. If you are young and/or find the Associative Memory exercise too easy, spend your time on the 2nd and 3rd exercises. 

By the way, you may use an anonymous email and name to access these exercises. Nevertheless, your identity and email address will remain confidential.

We have done a pilot study investigating the effect of these exercises through a controlled study on 14 individuals age 70-80 year old for 8 consecutive weeks, 3 days/week and one hour/day. The results being assessed by WMS, an idenpendent memory assessment, have been very encouraging. We are in the process of finalizing the control group results too and submit it to a journal for publication.

If you have any question or concern, you may contact me by email ( I also greatly appreciate your feedback.

In order to play the exercises first you need to make an account and  verify it by checking your email. The page for exercises and making an account is:

The games all have a brief instruction that opens up in the same window. But if you need more detailed instruction, please read below instructions.
