This cross-sectional study was conducted amongst patients who attended the general outpatient clinic and junior staff of the University of Nigeria Teaching Hospital (UNTH), Ituku-Ozalla.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aims and Objectives:<\/jats:title>\n                    <jats:p>To determine the normative scores for select neuropsychological battery test for the detection of neurocognitive disorder amongst Nigerians PLWHIV. A sample of 92 individuals received voluntary HIV testing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Eligibility criteria were being HIV negative, aged 18\u201364 years and formal education. We undertook a brief neuromedical examination to identify putative exclusion criteria. We sampled four NP tests covering seven cognitive domains and the motor speed component of the International HIV Dementia Scale (IHDS-MS). We presented the normative scores using statistics of mean, median, standard deviation (SD), kurtosis and skewness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>All the participants were Nigerians aged 18\u201364 years. Most (74.1%) of the participants were females. The mean and median ages of the participants were 42.6 \u00b1 11.42 years and 44 years, respectively. The effect of gender on NP performance was limited to the digit span test (DST)-forwards, while education affected all expect IHDS-MS and DST-backwards. The cut-off scores for defining mild and severe impairment varied (moving from 1SD to 2SD) for all cognitive domains except for IHDS-MS and DST.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>With these preliminary normative scores, it will be easier to identify and classify the severity of neurocognitive impairment amongst PLWHIV in Nigeria, thus facilitating the goal of keeping HIV-associated dementia to a minimum. The lack of variability in the IHDS-MS and DST is unfavourable.<\/jats:p>\n
