title: Neurocognitive functioning and HAART in HIV and hepatitis C virus co-infection.
abstract: OBJECTIVE
  This study examined the effects of HAART on neurocognitive functioning in persons with hepatitis C virus (HCV) and HIV co-infection.
  
  
  METHODS
  A prospective study examining neurocognitive performance before and after HAART initiation.
  
  
  METHODS
  Participant groups included a mono-infected group (45 HIV+/HCV- participants) and a co-infected group (20 HIV+/HCV+ participants). A neuropsychological battery (attention/concentration, psychomotor speed, executive functioning, verbal memory, visual memory, fine motor, and gross motor functioning) was used to evaluate all participants. After 6 months of HAART, 31 HIV+ mono-infected and 13 HCV+/HIV+ co-infected participants were reevaluated.
  
  
  RESULTS
  Neurocognitive functioning by domain revealed significantly worse performance in the co-infected group when compared to the monoinfected group on domains of visual memory and fine motor functioning. Assessment of neurocognitive functioning after antiretroviral therapy revealed that the co-infected group was no longer performing worse than the monoinfected group.
  
  
  CONCLUSIONS
  The findings of the current study suggest that persons with HCV+/HIV+ co-infection may have greater neurocognitive declines than persons with HIV infection alone. HCV+/HIV+ co-infection may accelerate the progression of HIV related neurocognitive decline.
