Document Summary
A common example is the distinction between dementia, with its multiple causes, and depression. Both dementia and depression may reflect sadness, concentration and attention difficulties, vegetative signs such as sleeping and eating difficulties and other similar symptoms. Degenerative disorders: by the nature of the term, degenerative disorders involve difficulties with destruction of neurons and/or specific areas within the central nervous system. In many of these difficulties, the loss of neurons or neural tissue is not repairable and the loss of abilities is permanent. The etiological factors are unknown for many of the degenerative disorders. These disorders tend to occur more often in the older population and as the population as a whole ages, more and more of these disorders are surfacing. Cortical dementias: cortical dementia refers to damage within the cerebral cortex and demonstrates a progressive decline in cognitive abilities. During the early stages of degenerative disorders, differences usually appear.
