the mental faculty that enables one to retain and recall previously experienced sensations, impressions, information, and ideas. The ability of the brain
to retain and to use knowledge gained from past experience is essential to the process of learning. Although the exact way in which the brain remembers is not completely understood, it is believed that a portion of the temporal lobe of the brain, lying in part under the temples, acts as a kind of memory center, drawing on memories stored in other parts of the brain.

screen memory a consciously tolerable memory serving to conceal or “screen” another memory that might be disturbing or emotionally painful if recalled.

Patient discussion about impaired memory
Q. Is forgetting where you parked your car a sign of a memory problem? Is forgetting where you parked your car a sign of a memory problem? Should you be concerned and consult your doctor about it?
A. This is a common concern that adults voice. However, I wouldn’t be concerned if it is just that. Forgetting where you parked your car is more a problem of inattention than of memory. Adults compared to the young are less good at Divided Attention. They are not as good at simultaneously thinking about an issue and paying attention to where they parked their car. They tend not to pay attention to where they are parked and not register this information in their mind in the first place. What you do not pay attention to, you cannot expect to remember. The solution is to make a habit of paying attention to where you are parked. Take a good look at the surroundings before you leave the parking lot and then you will notice fewer incidence of the problem.
Q. I want to improve my memory. I do a Sudoku every day and crossword puzzles. Do I need to do anything else?
A. I myself do believe that brain games (like sudoku, brain age, etc.) will help all of us to improve our brain function, and later in the future will help to DELAY the degenerative process of our brain.More discussions about impaired memory

That is, practice can certainly make people better at sudoku puzzles or help them remember lists more accurately. The improvement can even last for years. Similarly, people tend to retain skills and knowledge they learned thoroughly when they were younger. Unless the activities span a broad spectrum of abilities, though, there seems to be no benefit to general mental fitness.
For people whose work is unstimulating, having mentally challenging hobbies, like learning a new language or playing bridge, can help maintain cognitive performance. But the belief that any single brain exercise program late in life can act as a quick fix for general mental function is almost entirely f
