 AB    OBJECTIVES: To investigate the ability of clinical, laboratory and
       demographic variables to predict the presence of dementia and
       neuropsychological impairment in patients with CD4 count < 200.
       METHODOLOGY: 50 HIV- and 59 HIV+ subjects were assessed neurologically
       and neuropsychologically, and a subset of subjects underwent lumbar
       punctures. Logistic regression was used to determine which variables
       from a set including age, education, IQ, depression, anxiety, CD4 cell
       counts, haemoglobin, serum and CSF beta 2 microglobulin and neopterin,
       constitutional symptoms, past opportunistic infections and use of
       antiretroviral therapy predicted the occurrence of dementia according to
       the ADC rating scale, and cognitive impairment according to four
       criteria of neuropsychological abnormality. RESULTS: An increased
       likelihood of neurological and neuropsychological dysfunction was
       associated with a history of weight loss six months prior to assessment,
       diarrhoea at some time in the recent past, and a high level of serum
       neopterin at the time of assessment. A decreased likelihood of
       impairment was associated with a higher estimated IQ, more years of
       education, and use of zidovudine, but not ddI, for longer than two
       months at the time of assessment. CONCLUSION: The results support a
       model of increased cytokine production causing systemic and cerebral
       damage, and provide a simple clinical method for screening for the
       presence of ADC.
