Memory impairment

Refers to an individual who is in a state where he cannot remember or recall information or skills, which may be caused by a permanent or temporary memory disorder due to pathophysiological or situational reasons. Memory includes memorization, retention and reproduction, which is closely related to neuropsychological functions. According to neurophysiological and biochemical studies, memory is divided into transient memory (within minutes and seconds), short-term memory (days) and long-term memory (months, years). Memory and forgetting are accompanying, and forgetting has a time pattern and selectivity. The most recently forgotten material is the fastest to forget, and it gradually develops into oblivious events. Things that once attracted high attention are harder to forget.
