Forgetting what was just said is a kind of near memory loss, but not necessarily Alzheimer’s. Many elderly people may have amnesia, which is usually also manifested as forgetting what was just said, or not remembering what just happened. If it is Alzheimer’s, it depends on whether the patient has disorientation, such as getting lost easily, and not remembering who is who, as well as personality changes or other changes, so there are certain criteria for diagnosing Alzheimer’s. It is best to go to the hospital to see if it is Alzheimer’s. If a young person forgets what he or she just said, it’s not a memory problem, but a concentration problem. If the concentration is lax, such as having more things to do or being in a hurry, memory loss can easily occur in these cases. However, if you do a memory test and find that the memory test is normal and the score is very high, it should be a problem of attention. So if you forget what you just said, it depends on the specific situation, you can’t generalize, not all of them are Alzheimer’s.
