Memory Loss

Memory loss is unusual forgetfulness. You may not be able to remember new events, recall one or more memories of the past, or both. The memory loss may be for a short time and then resolve (transient). Or, it may not go away, and, depending on the cause, it can get worse over time. In severe cases, such memory impairment may interfere with daily living activities.
