Short-Term Memory Loss:
Short-term memory loss is one of the first symptoms of Alzheimer’s disease and is characterized by the inability of the patient to recall information that was just given to him/her. Asking the same question multiple times over the course of a day or two is a signal of short-term memory loss. Testing for Alzheimer’s may be a good idea if this symptom is growing worse.
Sensory Memory Loss:
Sensory memory is the shortest-term memory that relates to recalling sensory experiences such as seeing, hearing, tasting, etc., that occur in the past few seconds. Sensory memory loss is very subtle and not often noticed in detecting Alzheimer’s.
Working Memory Loss:
Working memory allows the brain to store limited amounts of information long enough to be able to process thoughts and to develop plans and ideas. Short-term memory and the working memory work together. Working memory loss is noticed in the early stages of Alzheimer’s disease.
Long-Term Memory Loss
Loss of long-term memories is usually visible at a later stage of the disease. Long-term memories are from a few weeks to early memories from life. Long-term memory loss is the last to be affected by Alzheimer’s disease as the process of memory moves from sensory to short-term to long-term.
