  1. Loss of neurons of origin of the adrenergic projection to cerebral cortex (nucleus locus ceruleus) in senile dementia

    ✓ Peer-reviewed alzhub usefulness score 53 out of 100. Neurology 1982-02-01 Getting a diagnosis

    To examine the possibility that senile dementia may be associated with a loss of noradrenergic neurons that innervate the cerebral cortex, we used a Quantimet 720 image analyzer to estimate the number of neurons in the nucleus locus ceruleus in elderly patients with the clinical diagnosis of senile dementia.

  2. Pathological verification of ischemic score in differentiation of dementias

    ✓ Peer-reviewed alzhub usefulness score 49 out of 100. Annals of neurology 1980-05-01 Getting a diagnosis

    Fourteen case histories of persons who had a histological diagnosis of either senile dementia of the Alzheimer type, multiinfarct dementia, or a mixed dementia composed of these two types and who showed evidence of a moderate to severe dementia on psychological testing were rated for the presence of thirteen clinical features comprising Hachinski's Ischemic Score.

  3. A light and electron microscopic study of experimental portal-systemic (ammonia) encephalopathy. Progression and reversal of the disorder

    ✓ Peer-reviewed alzhub usefulness score 36 out of 100. Laboratory investigation; a journal of technical methods and pathology 1977-06-01 Inflammation and the immune system

    A sequential light and electron microscopic study of cerebral cortex was performed in a rat model of portal-systemic encephalopathy produced by creating a portacaval shunt and followed by ammoniate resin feedings.

  4. Cerebral Blood Flow in Dementia

    ✓ Peer-reviewed alzhub usefulness score 53 out of 100. Archives of Neurology 1975-09-01 Vascular contributions

    Twenty-four patients of comparable age, blood pressure, and degree of dementia were classified by an "Ischemic Score" based on clinical features into "multi-infarct" and "primary degenerative" dementia.
