Source Journal of Neurology, Neurosurgery & Psychiatry. 1997 Oct Vol 63(4) 441-445 ISSN/ISBN 0022-3050 Language English Abstract There is a need for improvement in diagnostic accuracy for Alzheimer's disease. The aim of this study was to assess the diagnostic value of the combination of medial temporal lobe atrophy as seen on temporal oriented computed tomography (CT) and decreased temporoparietal uptake as assessed with single photon emission computerized tomography (SPECT). The study was conducted with125 patients (51-93 yrs old) with probable Alzheimer's disease, possible Alzheimer's, or miscellaneous memory disorders. For the diagnosis of probable Alzheimer's disease, the sensitivity of this association was 0.56, the specificity 0.93, the positive predictive value 0.95, and the negative predictive value 0.45. The diagnostic accuracy was 0.68. Both medial temporal atrophy and parietotemporal uptake decrease were present in 4 of 13 patients with possible Alzheimer's disease and 11 of 48 with miscellaneous memory disorders. The association was absent in 27 of 29 patients with frontotemporal dementia. The sensitivity of the association differed in mild stages of the disease. This association, although not sensitive, helps to select patients with high probability of Alzheimer's disease at an early stage which can be of interest for clinical and research purposes.

Source International Journal of Developmental Neuroscience. 1998 Nov-Dec Vol 16(7-8) 787-794 ISSN/ISBN 0736-5748 Language English Abstract There is increasing evidence that in Alzheimer's disease nerve growth factor (NGF) protein and mRNA content in post-mortem cortex is not decreased, but may be elevated, although the NGF-sensitive cholinergic basal forebrain neurons are preferentially affected. Postmortem NGF was measured in the temporal and frontal cortices of Alzheimer's disease patients, non-demented controls without Alzheimer's, as well as non-demented patients with betaA4 plaques who might be classified as preclinical cases. In the Alzheimer's disease group, an increase of up to 43% was found in NGF concentrations in the frontal and temporal cortex, compared to the 2 other groups. In a subgroup analysis of the non-demented patients with plaques, NGF concentrations were lower in the frontal cortex when betaA4 plaques were present (46% of the control temporal area) than in patients without evidence of frontal plaques (81% of the control temporal area). This NGF decrease was parallel to a similar decrease of choline acetyltransferase activity, which is regulated by NGF in the cholinergic basal forebrain. These findings support the hypothesis of lower cortical NGF content at the onset of plaque formation and of elevated NGF levels in advanced Alzheimer's.
