Magnetic resonance imaging and magnetic resonance spectroscopy in dementias

This article reviews recent studies of magnetic resonance imaging and magne tic resonance spectroscopy in dementia, including Alzheimer's disease, fron totemporal dementia, dementia with Lewy bodies, idiopathic Parkinson's dise ase, Huntington's disease, and vascular dementia. Magnetic resonance imagin g and magnetic resonance Spectroscopy can detect structural alteration and biochemical abnormalities in the brain of demented subjects and may help in the differential diagnosis and early detection of affected individuals, mo nitoring disease progression, and evaluation of therapeutic effect.
