Dementia and spastic syndrome to 10 yearsPathology: Pathology Recent studies have shown that macrophageal activation, resulting in elevated serum levels of interleukin (IL)-1β, IL-6, TNF-α and the soluble IL-2 receptor, is one of the drivers of the GD pathogenesis. The macrophageal activation could potentially explain some clinical features of adult type-1 GDThe pathological mechanism of CNS damage : The pathological mechanism of CNS damage is not fully understood. Infiltration of Gaucher cells into Virchov -Robin spaces has been demonstrated. Reports have described neuronal loss and neuro -degeneration with damaged neurons in the basal ganglia, nuclei of the midbrain, pons, medulla, cerebellum, dentate nucleus and hypothalamus. Recently , an association between GD and Parkinson’s disease has been discovered You do not have the permission to view this presentation.
