The pedunculopontine and laterodorsal tegmental nuclei comprising the pontomesencephalotegmental (PMT) cholinergic system were examined for the presence of neuropathology and loss of presumed cholinergic cells in patients diagnosed with Alzheimer's disease-senile dementia of the Alzheimer type (AD-SDAT), Parkinsonian dementia, and multi-infarct dementia.(More)
In addition to the well known structural stigmata which accompany the senile dementia of Alzheimer, attention is called to the presence of a group of robust changes which affect the fine vessels (capillaries, capillary arterioles and capillary venules), particularly of the cerebral cortex. These alterations include irregular pouches and excrescences on the(More)
The activity of reduced nicotinamide adenine dinucleotide (NADH)-diaphorase was examined histochemically in the amygdala, cortex and sublenticular substantia innominata (nucleus basalis of Meynert) of patients with Alzheimer's disease and senile dementia of the Alzheimer type (SDAT). Senile plaques were characterized by increased enzyme levels and the(More)
Spin-spin relaxation time (T2) was measured in the hippocampal formation, thalamus, and cortical white matter in 13 patients with probable Alzheimer's disease (AD), 11 elderly normal individuals, 23 healthy young persons, and 9 subjects diagnosed with multi-infarct dementia. A 0.04 tesla magnetic resonance scanner was used. Hippocampal T2 values for all AD(More)
The localization of the intracerebral microtubule-associated proteins tau (MAP-tau) has been compared to that of amyloid P component (AP), an extracerebral protein, by single- and double-antigen immunohistochemistry in neurofibrillary tangles of Alzheimer's brains. The results show that, individually, MAP-tau and AP may be observed in all stages of(More)

We have attempted to verify the presence of increased aluminum (Al) levels in Alzheimer's disease (AD) brains by energy dispersive X-ray microanalysis (EDX) and flameless atomic absorption spectrophotometry (AAS). Tissue from seven AD brains, mounted on carbon polymerized coverslips, were stained with Congo-red or treated immunohistochemically to allow(More)
Severe combined immunodeficient (SCID) mice previously transplanted with Lewis rat hematopoietic cells (SCID mouse-Lewis rat chimeras) developed experimental autoimmune encephalomyelitis (EAE) following injection with myelin basic protein (BP)-specific Lewis rat T lymphocytes. Rat T cells did not cause EAE in non-chimeric SCID mice. Thus, in addition to(More)
An immunohistochemical analysis utilizing antibodies to glial fibrillary acid protein (GFAP), microglia, beta-amyloid, amyloid P-component, neurofibrillary tangles (NFT), and microtubule associated protein-tau (MAP-tau) was performed on the cholinergic basal forebrain in Alzheimer's disease (AD). This severely compromised system, which includes the nucleus(More)
