In a review of the science on this topic, neuroscientist Dorit Shalom from Ben Gurion University in Israel proposed in 200922 that in autism there is damage to part of the brain most often associated with episodic remembering of personal events, the limbic-prefrontal system, but other types of memory remain spared. This means that people with autism are going to more generally have worse memories of their own lives. This is different from what we would usually classify as amnesia, as it is not a complete lack of ability to form these memories, just a deficit.
