Abstract
Zambia has substantially been affected by the HIV/AIDS epidemic with prevalence rates at 14% in a population estimated at 12 million. Yet, the extent of HIV-associated neurocognitive disorders (HAND) in this population remains to be clearly understood. A series of culturally appropriate neuropsychological (NP) assessments [International HIV Dementia Scale (IHDS), Color Trails Test 1 and 2, Grooved pegboard Test, and Time Gait Test] were used to test the effects of HIV on NP performance of HIV seropositive and seronegative individuals. Twenty-two percent HIV positive individuals ARV naïve met the criteria for IHDS-defined NP impairment. Gender significantly influenced the performance on NP tests with females performing more poorly compared to males. Larger studies that will accommodate gender differences and age are necessary to generate appropriate norms in Zambia in order to better assess the prevalence of HAND in the developing country setting.
Resumen
Zambia ha sido significamente afectado por la epidemia de VIH/SIDA, con tasas de prevalencia del 14% en una población estimada en 12 millones. Sin embargo, en cuestión a los trastornos neurocognitivos asociados con el VIH (TNAV) aún se desconoce en esta población. Una serie de evaluaciones neuropsicológicas (NP) culturalmente apropiados [Escala Internacional de Demencia asociada a VIH (EIDAV), las Pruebas Color Trails™ 1 y 2, La prueba tablero ranurado de clavijas, y la prueba del tiempo de marcha] se utilizaron para probar los efectos del VIH en el rendimiento NP de personas VIH seropositivos y seronegativas. Veintidós por ciento de las personas VIH positivas sin manejo previo con antiretrovirales cumplieron con los criterios de un deterioro NP definido como EIDAV. El genero influyo importantemente en el desempeño en las pruebas NP, con un rendimiento mas pobre en las femeninas en comparación con los masculinos. Estudios de mayores dimensiones que tomen en cuenta las diferencias de género y edad son necesarios para generar normas adecuadas en Zambia con el fin de evaluar mejor la prevalencia de los TNAV en el escenario de los países en desarrollo.
