Nephrosis Nephrosis Nephrosis is any of various forms of kidney disease (nephropathy). In an old and broad sense of the term, it is any nephropathy, but in current usage the term is usually restricted to a narrower sense of nephropathy without inflammation or neoplasia, in which sense it is distinguished from nephritis, which involves inflammation. It is also defined as any purely degenerative disease of the renal tubules. Nephrosis is characterized by a set of signs called the nephrotic syndrome. Nephrosis can be a primary disorder or can be secondary to another disorder. Nephrotic complications of another disorder can coexist with
Transneuronal degeneration neurons resulting from the disruption of input from or output to other nearby neurons. Anterograde and retrograde transneuronal degeneration is typically seen in humans around lesions in the limbic, visual, or dentate-rubro-olivary pathways. Lesions to the brain cause pathological changes that can cause anterograde transneuronal degeneration and lead to system degeneration. Brain lesions create structural or transient deafferntation (the interruption or elimination of sensory nerve impulses by injuring or damaging sensory nerve fibers) because injury to the area causes a loss of excitatory input to other areas in the brain, causing them to be less responsive to stimuli.
