Application of a Finite Mixture Model to Assess the Role of CD4+ T Cell Count as a Predictor of Memory Loss in HIV+ Patients

Introduction: Memory impairment is one of the most important complications in patients with HIV infection. The syndrome caused by reductions brain volume and count circulating CD4+ lymphocytes. This study was conducted to evaluate relationship between lymphocyte memory function HIV+ patients. Methods: descriptive-analytical on 150 referred Behavioral Disorders Counseling Center Kermanshah City. measured using Wechsler scale. patients' cell counts demographic information were extracted from their medical files. data recorded STATA version 16 software analyzed regression finite mixture models. Results: meansstandard deviations three classes 63.99 +/- 7.02, 75.01 14.72, 85.14 6.43. results showed that a decrease increased risk loss (P < 0.001). In addition, higher age 0.001), female gender lower education level 0.001) significantly associated an Conclusion: present confirmed findings previous studies noting as result immune system suppression, including depletion cells. Therefore, it necessary monitor cognitive these implement measures strengthen performance.
