Spatial Analysis of the Neuronal Density of Aminergic Brainstem Nuclei in Primary Neurodegenerative and Vascular Dementia: A Comparative Immunocytochemical and Quantitative Study U... by Yan Yang, Konrad Beyreuther, Horst P. Schmitt

“…A graph method was employed to analyse spatial neuronal patterns of pontine nuclei with ascending aminergic projections to the forebrain (nucleus centralis superior (NCS), raphes dorsalis (NRD) and locus coeruleus (LC)), in Alzheimer disease (AD), Huntington disease (HD), and vascular (VD) as well as “mixed‐type” (VA) dementia, compared with non‐demented controls (CO) and a small sample of brains from schizophrenics (“dementia praecox” (DP)). The quantitative evaluations by the “minimal spanning tree (MST)” were complemented by rough neurofibrillary tangle (NFT) counts and by semiquantitative immunohistochemical assessment of amyloid deposition, neuritic plaque formation, and cellular gliosis. …”

Paraphrenia revisited: psychotic states arising later in life. Why do psychiatrists tend to overlook it? by R. M. Sousa, S. Martins, J. Correia, N. Cunha

“…Kraepelin first used the term paraphrenia in 1912, to describe a psychotic disorder with much lighter impairment of emotion and volition, minimal to no cognitive deterioration (dementia) and personality preservation compared to dementia praecox.
