The ability to read is a nondeclarative memory, because once the skill of reading is mastered, it becomes an unconcious act, said Leslie Ungerleider of the National Institute of Mental Health. But remembering what has been read would be a declarative memory because it involves consciously retrieving the information. You're not alone, says Cynthia R. Green, director of the Memory Enhancement Program at Mount Sinai School of Medicine in New York. If the answer to all of these questions is yes, Green advises seeing a health professional experienced in assessing memory, such as a neurologist, psychiatrist or psychologist. Difficulties with memory can be caused by a wide variety of problems, including normal aging and stress.
Evidence suggests that sleep deprivation can impair memory.
Studies also point to sleep as an important way for the brain to consolidate what it has learned during the day. Physical activity helps the brain as well as the body by improving circulation, lowering blood pressure and increasing blood oxygen levels. Eat a well balanced diet. Vitamin B12 is just one of the vitamins necessary for neurological function. Depending on your age and general condition, doctors sometimes advise taking a vitamin supplement to help assure adequate nutritional intake.
