Do differences exist in the cognitive profile of mild Alzheimer 's disease and subcortical ischemic vascular dementia?
SIVD patients with mild dementia have greater deficits in visuospatial function, working memory and visuomotor speed and may also be more depressed compared to AD patients. Executive function tests in general do not distinguish the 2 groups, although timed executive tasks can separate them.
The SARS-CoV load is a determinant of clinical outcomes of SARS, and it is associated with polymorphisms of genes involved in innate immunity, which might be regulated in an age- and sex-dependent manner. The findings of the present study provided leads to genes involved in the host response to SARS-CoV infection; if substantiated with functional studies, these findings may be applicable to other newly emerged respiratory viruses (e.g., the influenza pandemic strain).
