Cognitive impairment such as dementia and mild cognitive impairment has emerged as a major health problem in Korea due to rapidly aging population. Although clinical assessments form the basis of evaluating a patient with dementia, neuroimaging tools have increasingly used. In the past, the neuroimaging tools in dementia have been restricted to exclude neurosurgical lesions. However, modern neuroimaging extends beyond this traditional role of excluding other conditions and has a key role in the clinical investigation of Alzheimer’s disease and of other dementias. Neuroimaging has played and is playing an important role in detecting reversible, treatable causes of dementia, and in characterizing the dementia syndromes by demonstrating structural and functional signatures that can aid in their differentiation. In this review, I report the recent findings that used structural and functional neuroimaging techniques for the study of various dementing conditions. The combined use of neuroimaging with clinical, neuropsychological tests can improve the sensitivity and the specificity to make a diagnosis of cause of dementia
