title: Selective increase in lipid peroxidation in the inferior temporal cortex in Alzheimer's disease.
abstract: The concentration of a product of lipid peroxidation (malondialdehyde) was determined in six areas of neocortex of 8 subjects with Alzheimer's disease and 8 control subjects. Malondialdehyde concentration was significantly increased by incubation with iron and ascorbate in all samples. Both basal and iron/ascorbate-stimulated malondialdehyde concentration were higher in the inferior temporal cortex of Alzheimer subjects than corresponding controls; other regions were unaffected. Basal concentrations of malondialdehyde correlated with age in both the inferior parietal lobule and the sensory/motor cortex.
