THE DEMENTIAS - CORRELATION OF CLINICAL-FEATURES, PATHOPHYSIOLOGY, AND NEURORADIOLOGY

Current methods of neuroimaging have revolutionized the examination of patients with dementia. Clinical examination of these patients has id entified cortical and subcortical patterns of dementia. Each of these patterns can be caused by various diseases. Mixed patterns also occur and also have several possible causes. Neuroimaging can be quite usefu l in confirming the clinical assessment of the pattern of dementia and in further refining the diagnosis. We review the pathophysiologic bas is of and the clinical and neuroimaging findings in dementia, both cor tical and subcortical. The roles of neuroimaging in diagnosis, prognos tic assessment, and treatment evaluation are discussed.
