The impact of disrupted cortico-cortico connectivity: a long-term follow-up of a case of focal retrograde amnesia.
We report a long-term follow-up study of case JM, who demonstrated a focal retrograde amnesia (FRA) as a consequence of cerebral vasculitis. The present study showed that, several years post-onset, JM experienced considerable impairment in episodic retrograde memory, with normal anterograde autobiographical memory. Further investigations demonstrated that she showed no evidence of accelerated forgetting, unlike some other cases of FRA. Knowledge of people, pre- and post-illness, was also normal. Her ability to recall details of famous public events was good (though weaker for pre-illness events). JM's pattern of impairment is discussed in the context of other recent cases of FRA and developments in models of normal memory function.
