Vascular thalamic XXXX : a reappraisal.

@entity1 @entity2806 @entity146 @entity2730 @entity9479 @entity1188 @entity2414
In @entity1 @entity1188 in the mesial and anterior regions of the thalami are frequently associated with @entity2730 . In this review paper, we scrutinized 41 papers published between 1983 and 2009 that provided data on a total of 83 @entity1 with the critical @entity2806 (i.e. 17 @entity1 with right-sided lesions, 25 with left-sided lesions and 41 with bilateral lesions). We aimed to find answers to the following questions concerning the vascular @entity9479 : (i) Which qualitative pattern of @entity2414 (and associated cognitive and @entity146 ) do these @entity1 present? (ii) Which lesioned intrathalamic structures are primarily responsible for the @entity2730 ? (iii) Are the recollection and familiarity components of declarative memory underlain by the same or by different thalamic structures? Results of the review indicate that, similar to @entity1 with @entity2730 due to mesio-temporal lobe damage, @entity1 with vascular thalamic @entity2730 display a prevalent deficit of declarative anterograde long-term memory, a less consistent deficit of declarative retrograde long-term memory and substantially spared short-term and implicit memory. Unlike mesio-temporal lobe @entity1 , however, vascular thalamic amnesics often present @entity146 similar to those observed in @entity1 with frontal damage. The presence of an @entity2730 in @entity1 with thalamic @entity1188 is strongly predicted by involvement of the mammillo-thalamic tract, which connects the anterior nuclei complex to the hippocampus proper via the fornix and the mammillary bodies. Finally, data reported in a few single cases provide support for the hypothesis that thalamic regions connected to distinct areas of the mesio-temporal lobe play differential roles in recollection and familiarity processes. The mammillo-thalamic tract/anterior nuclei axis seems primarily implicated in recollective processes, whereas the ventroamygdalofugal pathway/medio-dorsal axis primarily underlies familiarity processes.
