Evaluating the neurocognitive complications of SLE. Lessons from HIV disease.
In this paper, we have attempted to define some of the theoretical, methodological, and practical issues involved in the use of NP testing to detect, classify, and monitor neurocognitive impairment secondary to systemic lupus erythematosus. We have drawn on experience with other clinical entities-primarily HIV disease-to inform this discussion. We have argued that for the purposes of studying NP-SLE, NP testing remains the gold standard and is also the most practicable approach in most settings, be they clinical or research. At the same time, the selection of NP tests must be carefully considered, particularly in a disease such as SLE in which the neurocognitive complications arise from several etiological mechanisms, affect people at various points in the course of disease, and in which the anatomic distribution of pathology in the brain varies from patient to patient. In this context, it is safest to select a test procedure that assesses all major areas of cognitive functioning with tests for which adequate demographically adjusted norms exist. In this way, a more reliable diagnosis of neurocognitive impairment, mild neurocognitive disorder, or dementia may be made. A reliable and valid neurocognitive diagnosis is the first step in monitoring patients clinically, in designing research aimed at neuropathogenesis, or in the design of treatment trials geared toward neuroprotection or neuroremediation.
