Abstract: | Cross-sectional X-CT and 123I-IMP-SPECT studies comparing patients with presenile dementia with motor neuron disease (52-year-old, female), with Alzheimer's disease (51-year-old, male) and Pick's disease (49-year-old, male), have found a pattern of reductions in regional cerebral blood flow; the most severe reductions have been in fronto-temporal regions in cases of Pick's disease and presenile dementia with motor neuron disease. 123I-IMP-SPECT in a patient with presenile dementia with motor neuron disease differed significantly from uptake in a case with Alzheimer's disease. Although these findings should be evaluated as part of a prospective longitudinal study with X-CT and 123I-IMP-SPECT, it could be suggested that the development of these diseases has different pathophysiologies. |
