The fact that the individuals in our study population were
participating in a project, which included measures of cognitive
functioning, allowed us to examine the association of detectable
ATCV-1 DNA in the pharynx and performance on a range of
cognitive tests. Surprisingly, the presence of ATCV-1 DNA in
the oropharynx was associated with modest but statistically significant
decreases in performance on tests including Trails A and
RBANS Attention, both of which measure visual processing and
visual motor speed.
