  • Title: Stereological quantification of the cerebellum in patients with Alzheimer's disease.
    Author: Andersen K, Andersen BB, Pakkenberg B.
    Journal: Neurobiol Aging; 2012 Jan; 33(1):197.e11-20. PubMed ID: 20728248.
    Abstract:
    Nonquantitative studies indicate that the cerebellum is neuropathologically affected in Alzheimer's disease; however, no quantitative studies on the subject have yet been conducted. Ten cerebella from elderly female subjects with severe Alzheimer's disease and 10 age- and gender-matched controls were examined. The cerebellum was divided into 5 regions and the Purkinje and granule cell number and density, cortical volume, molecular and granular layer volume and thickness, white matter volume, surface area, and the Purkinje cell gradient were stereologically estimated. There was no significant difference between the groups in Purkinje or granule cell number or density, and no overall difference in Purkinje cell gradient. However, there was a significant 12.7% reduction in total cerebellar volume in the Alzheimer's group and significant localized differences between the groups regarding other parameters. The relative lack of neuropathological changes in the cerebellum of severely demented Alzheimer's patients suggests that neuronal cell bodies on a global scale apparently still are intact.
