Abstract: Several histopathological studies suggest that amyloidogenesis in dementia of the Alzheimer type is accompanied by activated glia and glia-derived cytokines, leading to chronic, self-propagating, cytokine-mediated molecular and cellular reactions. As studies regarding inflammatory changes in cerebrospinal fluid of patients with dementia of the Alzheimer type has been inconclusive, we set up a prospective study to assess cerebrospinal fluid levels of interleukin-1beta, interleukin-6, interleukin-10, interleukin-12, soluble interleukin-2 receptor, interferon-gamma, tumor necrosis factor-alpha and neopterin in 20 patients with dementia of the Alzheimer type and 20 age- and sex-matched controls. Comparing both groups, no significant differences in concentrations and specific activities could be revealed. An additional 22 patients were included to enlarge the study population. No statistically significant differences were shown comparing patients (n=42) with the control group (n=20). We conclude that the immune-mediated inflammatory changes found in histopathological studies are not reflected in cerebrospinal fluid of patients with dementia of the Alzheimer type. Probably, cytokine production appears very localized in the central nervous system, not allowing representative detection in cerebrospinal fluid. Further studies assessing cytokine levels in various regions of central nervous system of patients with dementia of the Alzheimer type will be of interest to confirm this hypothesis
