概要:
I described the radiological findings of dementia focussing on magnetic resonance imaging (MRI). The atrophy of subiculum is the initial sign and marker of the Alzheimer type dementia (ATD), irrespective of the type of presenile or senile onset. Even at this early stage, SPECT can reveal the poor circulation in temporal lobes, as well as other cerebral cortices. In the middle FAST stage of ATD, the atrophy of medial temporal lobe (i. e. hippocumpal and parahippocampal gyri) becomes commonly. In accordance with progression of dementia, marked atrophy of cerebral cortices, marked ventricular dilatation and white matter lesions become obvious in AD (presenile onset). On the other hand, in the cases of SDAT (senile onset), fronto-parietal cortices become in less atrophic than temporal cortices respectively, and result in limited ventricular dilatation, never prominent as observed in advanced AD. The radiological criteria of multi-infarct dementia, the major type of vascular dementia, should be considered by taking acount of the severity of dementia and the damaged areas due to multiple cerebral infarction. We should be careful to make a diagnosis of vasuclar dementia for the demented patients with minimal cerebral infarction. Pick's disease has exhibits already the characteristic patterns of brain atrophy even at the onset of dementia. Sharp edged cortical atrophy (Knife-Edge sign) at early stage and fronto-temporal lobar atrophy at advanced stage are the hallmarks of Pick's disease. Since not all radiologists are familiar with dementia, and the dimentia has no need for urgent diagnosis, so the teleradiology is a good application for evaluation of radiological findings of patients with dementia. 続きを見る
