Brain Degeneration and Aging
Many diseases result in degeneration of the nervous system. To name a few: infection, multiple sclerosis, and tumors destroy neuronal tissue. However, the term neurodegenerative disorders refers to a group of diseases that share the characteristic of death of subsets of specific classes of neurons. Another common feature of the class of neurodegenerative disorders is the fact that they are idiopathic, the etiology of these diseases is not completely understood. With increasing knowledge of the pathogenesis of these diseases, disorders that are presently classified as neurodegenerative will be grouped among diseases with a known pathogenesis, and consequently, the list of degenerative disorders will decrease. This paper discusses the neuroradiological aspects of a number of disorders that are presently considered to be neurodegenerative.
