Clinical investigations of Alzheimer's disease (AD) have been limited by diagnostic inaccuracy. We employed explicit clinical inclusion and exclusion criteria to identify subjects with senile dementia of the Alzheimer type (SDAT). In a consecutive series of 26 postmortem examinations from this sample, AD was histologically verified in all subjects and was(More)
The historical events in the evolution of Alzheimer's disease are reviewed, including the initial description by Alois Alzheimer and the subsequent controversy regarding the nosological specificity of this entity. The similarity of senile dementia and Alzheimer's disease is emphasized. The basis for the modern concept of Alzheimer's disease as premature or(More)
Ophthalmoplegia is rarely observed in patients with amyotrophic lateral sclerosis (ALS). We describe a patient with ALS in whom ophthalmoplegia, initially appearing midway in her course, progressed to total paralysis of extraocular movements by the time of death. In addition to the usual postmortem findings of ALS in the brain stem and spinal cord, there(More)
Six cases of adult dementia with mesolimbic pathology are reported. The core clinical syndrome consists of parkinsonism, progressive dementia, and behavioral disturbances (generally depression). The histopathologic findings uniformly include a loss of pigmented neurons in the ventral tegmental area plus neurofibrillary tangles and/or cell loss in the(More)
Three autopsied cases of congophilic angiopathy have been studied by means of polarized light microscopy and in 2 of these, biopsy material is available for electron microscopic study. All 3 patients had a surgical procedure and a subsequent massive hemorrhagic episode. Two of these patients had clinical evidence of dementing syndrome, for which shunts were(More)
We used tyrosine hydroxylase immunoreactivity (TH) to mark dopaminergic fibers in cerebral tissue from adult persons with Parkinson's disease (PD) or Alzheimer's disease (AD). In the PD cases we found a loss of dopaminergic neurons in the ventral tegmental area (VTA), severely reduced TH fibers in dopaminergic terminal fields (particularly in the(More)
