Patterns of Cognitive Impairments among Heroin and Cocaine Users: The Association with Self-Reported Learning Disabilities and Infectious Disease
Severtson, Stevan G.; Hedden, Sarra L.; Martins, Silvia S.; Latimer, William W.
Journal of Learning Disabilities, v45 n2 p139-150 Mar-Apr 2012
This study used data from six neuropsychological measures of executive function (EF) and general intellectual functioning (GIF) administered to 303 regular users of heroin and/or cocaine as indicators in a latent profile analysis (LPA). Results indicated the presence of three profiles: impaired GIF and EF profile (30.8%), intact GIF and EF profile (58.8%), and high GIF/intact EF profile (10.4%). Using a multinomial logistic regression, it was determined that individuals who reported being diagnosed with either a learning disability (LD) and/or attention-deficit/hyperactivity disorder (ADHD) were more likely to be in the impaired GIF and EF profile than other profiles. Results from a logistic regression indicated that the impaired GIF and EF profile was associated with a greater prevalence of past hepatitis B and/or C infection. Implication for harm reduction and treatment programs and the need to take into account individuals with LD and ADHD are discussed. (Contains 4 tables and 1 figure.)
