Memory is always impaired. Initially, short-term memory is affected, but as the disease progresses, it will also include long-term memory (usually in advanced disease).
Short-term memory is the ability to form new information. Examples of impaired short-term memory include misplacing articles, forgetting appointments, repeating oneself, and forgetting the details of recent events. As the memory impairment progresses, the person will increasingly live in the past.
