The Mem-Trax Memory Test

This simple visual memory test is a quick screening tool that will help give you an idea how your visual memory is functioning.

It is in no way considered a diagnosis.

The ability to remember visual-spatial information is a function of the right side (hemisphere) of your brain.

Therefore- this screen is a measure of memory-related right-sided brain function.

If your brain is degenerating due to Alzheimer's or other brain disease- it tends to degenerate on both sides.

So by assessing brain function on one side can give experts a clue as to what might be happening on the other side.

Clearly- if the results of this screen indicate poor performance- a more thorough workup is needed.

This screen is known as the Mem-Trax memory test- and was developed by Dr. J. Wesson Ashford and colleagues at the Stanford University School of Medicine in partnership with the Veteran's Affairs Aging Research Center in Palo Alto, CA.

Dr. Ashford has been developing screening instruments for many years.

He is considered a pioneer and leading expert in test development for early detection of memory disorders.

The Mem-Trax memory test represents his most recent work.

A special thanks goes out to Dr. Ashford for his continued efforts and lifelong commitment of developing screening platforms.

Before taking the test- print out this answer sheet to record your answers. (You will need Adobe Reader to view the answer sheet.)

Once you have the answer sheet in hand you are ready to take the test.

You will need to remove all distractions while you take the test.

On your computer you will see 50 pictures presented one at a time- with numbers in the upper left hand corner.

Each picture is represented by a number on the answer sheet.

The pictures will stay on the screen for 4 seconds. Carefully look at each picture.

If you see a picture that you have seen before, on the answer sheet- fill in the circle next to that number.


Less than 3 mistakes is normal.

Please note that the memory test will download automatically to your computer. Open it with Powerpoint (part of Microsoft Office) or OpenOffice on a PC, or Powerpoint, NeoOffice or Keynote on a Mac.
