Functional retrograde amnesia RA is a rare pathology and has been rarely studied in detail across different patients. We extensively examined five functional RA patients and compared their neuropsychological profile including anterograde and retrograde memory performance, executive functions, emotional processing, and formally assessed psychiatric symptoms. Across patients, neuropsychological deficits beyond RA were most consistently seen in executive functions and attention suggesting that these dysfunctions contribute to the remote memory deficit. In a majority of the patients, problems in social cognition and emotional behaviour were reflected in Theory of Mind deficits and accompanying psychiatric symptoms. Aberrances in a measure of social desirability were detected, pointing to repressive tendencies in three out of the five patients. Future studies of functional RA patients may investigate more specifically which frontal-lobe associated dys- functions contribute to the memory retrieval deficit.

Forget Me Not: History's 17 Most Bizarre Amnesia Cases | Live Science
An international team of neuroscientists has described for the first time in exhaustive detail the underlying neurobiology of an amnesiac who suffered from profound memory loss after damage to key portions of his brain. EP's story is strikingly similar to the more famous case of HM, who also suffered permanent, dramatic memory loss after small portions of his medial temporal lobes were removed by doctors in to relieve severe epileptic seizures. The surgery was successful, but left HM unable to form new memories or recall people, places or events post-operation. HM later identified as Henry Gustav Molaison was the subject of intense scientific scrutiny and study for the remainder of his life. When he died in at the age of 82, he was popularized as "the world's most famous amnesiac.

Anterograde amnesia is a condition in which a person is unable to create new memories after an amnesia-inducing event. At the same time, a person with this type of amnesia has intact long-term memories from before the incident. Before we delve into more detail about anterograde amnesia, it will be helpful to learn a bit about the different types of memory that can be affected by amnesia. This type of memory refers to the recollection of facts whether as part of a specific event or just as unrelated information.
In , Cochrane was involved in a motorcycle accident that left him with severe anterograde amnesia , as well as temporally graded retrograde amnesia. Like other amnesic patients patient HM , for example , Cochrane had his semantic memory intact, but lacked episodic memory with respect to his entire past. Cochrane was born in as the oldest of five children and grew up in the suburbs of Toronto , Ontario , Canada. After attending a community college to study business administration he obtained a job at a manufacturing plant, which he held until the time of his motorcycle accident. Cochrane died on March 27, , at the age of
