Neuropsychological Analysis of an Amazing Memory

What is it about?

This is a detailed case study of patient MM, a man with extraordinary memory for both personal, autobiographical memory and general semantic and historical information. The results of psychological tests, cognitive tasks, and brain imaging analyses are described.

Why is it important?

Much of our knowledge about the brain systems underlying human memory come from patients with amnesia due to brain dysfunction. Studying persons with highly superior autobiographical memory (HSAM) and other forms of extraordinary memory adds a new and important perspective.

It has been a pleasure getting to know patient MM. He never ceases to amaze me with his feats of memory. Although he sees his memory as a "gift," he also describes it as a burden at times.

It was such a pleasure working with patient MM. Patients like him teach us so much about how memory works or how it can fail us. I am very grateful for all the time that MM and patients like him make available to participate in our studies.
