Regional cerebral blood flow measurements in the clinical evaluation of demented patients. 1997

The clinical usefulness of two-dimensional measurements of regional cerebral blood flow (rCBF) for diagnosis of dementia is discussed on the basis of data from 150 patients with autopsy-based diagnosis. The specificity of Alzheimer's disease is found to be very good but the sensitivity only in the order of 75-80%, the majority of the mislabelled cases having selective incomplete white matter infarcts in addition to their Alzheimer pathology. Frontal lobe dementia is recognized by rCBF with high sensitivity but fairly low specificity due to the fact that frontal flow decreases are shared with several other disorders. Regarding cerebrovascular dementia the sensitivity is rather good (95%) while specificity is somewhat lower (70-75%). It is argued that rCBF should be interpreted diagnostically only when clear-cut findings are made preferably in a series of measurements. The noninvasiveness, repeatability, low radiation dose and low cost makes the present method an excellent tool for research as well as for clinical routine use.

D003704	Dementia	An acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning. The dysfunction is multifaceted and involves memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and other executive functions. The intellectual decline is usually progressive, and initially spares the level of consciousness.

D000368	Aged	A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available.	Elderly
D000544	Alzheimer Disease	A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.
