Remote memory in a XXXX with @entity2730 due to hypoxia.

@entity1 @entity2414 @entity5186 @entity2730
It has been suggested that @entity2730 @entity1 suffer a selective loss of episodic memory while semantic memory remains well preserved. To assess the validity of this idea we studied remote memory in an @entity2730 @entity1 , (M.R.L.), using several different measures that differ in the extent to which they engage episodic or semantic memory. On two different versions of the Albert et al. (1979) remote memory battery M.R.L. displayed severe @entity5186 ( @entity5186 ) extending backwards in time for about 15 years with excellent preservation of older memories. With standard recall instructions his overall performance on the Crovitz test of autobiographical memory was impaired and all of M.R.L.'s specific, temporally dated memories were given from the first half of his life. When asked to reconstruct his past residential history in detail, M.R.L. provide specific and generally accurate information for residences occupied from his boyhood until 1970, but thereafter his memory became quite unreliable. On a test of knowledge of terms commonly employed in the surveying profession, in which he worked for the past 20 years, M.R.L.'s performance was also impaired. The consistent pattern of @entity5186 displayed by this @entity1 on all of the tests of remote memory indicates that both @entity2414 are impaired in @entity2730 .
