Dementia, the Amnesic Syndrome, and the Neurology of Intelligence and Memory T2 Adams and Victor's Principles of Neurology, 10e YR 2014 FD 2014 PB The McGraw-Hill Companies PP New York, NY SN 978-0071794794 LK neurology.mhmedical.com/content.aspx?aid=57616655 RD 2023/03/25 AB Increasingly, as the number of elderly in our population rises, the neurologist is consulted because an otherwise healthy person begins to fail mentally and loses his capacity to function effectively at work or in the home. This may indicate the development of a degenerative brain disease, a brain tumor, multiple strokes, chronic subdural hematomas, drug intoxication, chronic meningoencephalitis (such as caused by HIV or syphilis), normal-pressure hydrocephalus, or a depressive illness. Formerly, when there was little that could be done about these clinical states, no great premium was attached to diagnosis. But there are now effective means of treating several of these conditions, and in some instances, of restoring the patient to normal mental competence. Moreover, diagnostic technologies allow earlier recognition of the underlying pathologic process, thus improving the chances of recovery or of preventing the disease's progression.
