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 is not present after upper motor neuron lesions in stroke patients. In addition cortico spinal tract lesions do not cause anterograde transneuronal degeneration of spinal anterior horn cells. Disconnection syndromes, defined as any neurologic disorder caused by an interruption in impulse transmission along cerebral fiber pathways, can cause white matter brain lesions, leading to secondary neuronal loss and transneuronal degeneration. Secondary neuronal loss occurs as a result in areas that are strongly connected with the severed tracts or restricted cortex during an anterior temporal lobectomy. Temporal lobe lesions also cause transneuronal degeneration, the effects of which can be seen
