Cognitive changes in asymptomatic drug-naïve human immunodeficiency virus type 1 clade C infection.

Asymptomatic human immunodeficiency virus (HIV) infection is associated with impaired cognitive functioning in both clade B and C infections. The nature of cognitive change longitudinally has not been studied in asymptomatic clade C infection. The present study evaluated changes in neuropsychological functioning over a 2(1/2)-year period in a cohort of HIV-1 clade C-infected asymptomatic individuals from South India.

Neuropsychological deficits in human immunodeficiency virus type 1 clade C-seropositive adults from South India.
