“…The semantic memory loss in this patient extended to vocabulary, arithmetic, and geographical knowledge, but his recollection of personally experienced events from his entire life was excellent. A more severe deficit of semantic than episodic retrograde memory in patients with left hemisphere temporal damage has also been reported in single case investigations by Markowitsch et al (1993) and Yasuda et al (1997) and in groups of epileptic patients before (Lah et al, 2006) and after left temporal lobectomy for the treatment of pharmacologically resistant epilepsy (Barr et al, 1990).…”

Retrograde episodic and semantic memory impairment correlates with side of temporal lobe damage

Patients with damage to the mesial and anterior portions of the temporal lobes suffer from a memory impairment involving both anterograde and retrograde amnesia. In the retrograde domain, it has been suggested that the relative severity of autobiographical and nonautobiographical memory impairment may depend on the prevalent side of the temporal damage. Here we present two patients suffering from damage to the mesial and anterior portions of the temporal lobes (hippocampal formation, parahippocampal gyrus and polar cortex) as a result of herpes encephalitis. In the first case, A.S., damage predominantly affected the right temporal lobe, whereas in the second patient, R.S., the damage was bilateral but more severe on the left side. A detailed investigation of the retrograde memory deficit demonstrated a partial double dissociation between the two patients, with A.S. almost exclusively impaired in the autobiographical domain (both episodic and semantic) and R.S. with poor performances in all domains, but much more severe in the nonautobiographical (both public events and general semantic knowledge) than in the autobiographical one. These findings reinforce the view of specialization of right and left temporal lobes in the retrieval of retrograde autobiographical and nonautobiographical memories, respectively.

“…Damage to the MTL, particularly the right MTL, results in spatial deficits (O'Keefe and Nadel, 1978;Morris et al, 1999;Smith and Milner, 1981); however, unilateral right MTL damage does not produce profound global amnesia (Barr et al, 1990). In this case, our approach has identified a region involved in the "consensus theory" of explicit memory.…”

This special issue of Cortex focuses on the relative contribution of different neural networks to memory and the interaction of 'core' memory processes with other cognitive processes. In this article, we examine both. Specifically, we identify cognitive processes other than encoding and retrieval that are thought to be involved in memory; we then examine the consequences of damage to brain regions that support these processes. This approach forces a consideration of the roles of brain regions outside of the frontal, medialtemporal, and diencephalic regions that form a central part of neurobiological theories of memory. Certain kinds of damage to visual cortex or lateral temporal cortex produced impairments of visual imagery or semantic memory; these patterns of impairment are associated with a unique pattern of amnesia that was distinctly different from the pattern associated with medial-temporal trauma. On the other hand, damage to language regions, auditory cortex, or parietal cortex produced impairments of language, auditory imagery, or spatial imagery; however, these impairments were not associated with amnesia. Therefore, a full model of autobiographical memory must consider cognitive processes that are not generally considered 'core processes,' as well as the brain regions upon which these processes depend.

“…Semantic memory de¢cits extended to vocabulary, arithmetic and geographical knowledge, and appreciation of concepts such as geometrical forms; but recollection of personally experienced events from the age of 6 to 18 years was excellent. Disproportionate impairment of public knowledge compared with autobiographical memories has also been noted in patients with left temporal lobe epilepsy or temporal lobectomy (Barr et al 1990;Kapur et al 1989). This has also been noted in two cases of irradiation necrosis to anterior and inferior temporal lobe structures (Kapur et al 1994;Yasuda et al 1997).…”

Retrograde amnesia in neurological disorders is a perplexing and fascinating research topic. The severity of retrograde amnesia is not well correlated with that of anterograde amnesia, and there can be disproportionate impairments of either. Within retrograde amnesia, there are various dissociations which have been claimedöfor example, between the more autobiographical (episodic) and more semantic components of memory. However, the associations of di¡erent types of retrograde amnesia are also important, and clari¢cation of these issues is confounded by the fact that retrograde amnesia seems to be particularly vulnerable to psychogenic factors. Large frontal and temporal lobe lesions have been postulated as critical in producing retrograde amnesia. Theories of retrograde amnesia have encompassed storage versus access disruption, physiological processes of`consolidation', the progressive transformation of episodic memories into a more`semantic' form, and multiple-trace theory. Single-case investigations, group studies and various forms of neuroimaging can all contribute to the resolution of these controversies.
