Lb rüb pathology is a major cause of stroke and mortality, lb rüb. Studies on prevalence of cerebrovascular pathologies in dementia with Lewy bodies DLBs and Parkinson disease PD patients are scarce and contradictory. We aimed to determine the prevalence and severity of cerebrovascular pathologies in DLB and PD and to analyze their relationship to LB pathology.

Cerebrovascular pathology is a major cause of stroke and mortality. Studies on prevalence of cerebrovascular pathologies in dementia with Lewy bodies DLBs and Parkinson disease PD patients are scarce and contradictory. We aimed to determine the prevalence and severity of cerebrovascular pathologies in DLB and PD and to analyze their relationship to LB pathology. In conclusion, DLB and PD patients with advanced LB pathology were less likely to show severe cerebrovascular disease or history of stroke. Cerebrovascular pathologies have been recognized as a major cause of stroke and mortality in the elderly 1 and may coexist with other age-related diseases, such as Lewy body LB disease 2, 3 and Alzheimer disease AD Disturbances of cerebral blood flow are frequent in DLB and PD 2, 9, 10 , and they might influence clinical courses of the diseases.

As reported in previous studies, LB and LN were most prevalent in the substantia nigra, ventral tegmental area, pedunculopontine and raphe nuclei, periaqueductal gray, locus coeruleus, parabrachial nuclei, reticular formation, prepositus hypoglossal, dorsal motor vagal and solitary nuclei. Additionally we were able to demonstrate LB and LN in all cranial nerve nuclei, premotor oculomotor, precerebellar and vestibular brainstem nuclei, as well as LN in all brainstem fiber tracts. According to this staging system, neuronal LB and LN are first seen in the dorsal motor vagal nucleus and intermediate reticular zone of the medulla oblongata. We examined the brainstem of eleven individuals with clinically advanced synucleinopathies five PD, one PDD and five DLB patients: one female, ten males; age at death: Overview of the synucleinopathy patients examined. Diagnostic neuropathological examination of the brains of the synucleinopathy patients was performed on thin tissue sections by an experienced neuropathologist W. Following incubation with the biotinylated secondary antibody, positive immunostainings were visualized with the AB complex and diaminobenzidine. Figures were arranged using the Photoshop CS3 software. The neuropathological assessments of the immunoreactive inclusion pathologies in brainstem greys were performed independently by J. Mahlke and U. Seidel and U.

Issue Section:. Following incubation with the biotinylated secondary antibody, positive immunostainings were visualized with the AB complex and lb rüb. Therefore, we confine our discussion on the possible functional consequences of the newly described pathology in the cranial nerve, premotor oculomotor, precerebellar and vestibular nuclei and associated brainstem fiber tracts, lb rüb.

Acta Neuropathologica Communications volume 9 , Article number: Cite this article. Metrics details. Socioeconomic disadvantage is associated with greater risk of dementia. This has been theorised to reflect inequalities in cognitive reserve, healthcare access, lifestyle, and other health factors which may contribute to the clinical manifestation of dementia. We aimed to assess whether area deprivation in the United Kingdom was associated with greater risk or severity of the specific neurodegenerative diseases which lead to dementia in a multi-centre cohort with autopsy assessment. Participants underwent clinical assessment prior to brain tissue donation post-mortem. Each then underwent detailed, standardised neuropathological assessment. These findings were not explained by a greater risk of diabetes or hypertension, APOE genotype, alcohol misuse or tobacco smoking, sex, or age differences. A sensitivity analysis conditioning on baseline cognitive impairment did not meaningfully change the observed association. Socioeconomic disadvantage may contribute to dementia incidence through a greater severity of specific neuropathological changes neurofibrillary tangles, neuritic plaques, and cerebral amyloid angiopathy , independent of other indirect influences.

Thal, MD. Rob A. Brain Pathol 23 — Advanced Search. Hemorrhages and WMLs were recorded separately and were designated as present or absent regardless of their sizes. Our findings reveal an inverse relationship between the major cerebrovascular pathologies and the severity of LB pathology. This graph plots the first 2 components' loadings against each other.

To confirm the AS diagnosis, blocks from the most severely affected arteries were embedded in paraffin, and tissue sections were stained with elastica van Gieson. Gerrits NM Vestibular nuclear complex. Article Navigation. This assessment, however, might have been biased by a floor effect, that is, the presence of mild AD pathology in all these groups.

Semin Neurol 27 — Finally, the esophageal phase of swallowing subserves peristaltic transport of foods or fluids to the stomach which is coordinated by the neuronal activity of the ambiguus and dorsal motor vagal nuclei 42 , In conclusion, DLB and PD patients with advanced LB pathology were less likely to show severe cerebrovascular disease or history of stroke.
