Dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD) share common clinical, neuropsychological and pathological features. In clinical diagnosis, distinguishing between these conditions and other dementia subtypes such as Alzheimer's disease (AD) can be difficult. Despite the development of consensus diagnostic criteria, sensitivity for diagnosis remains low, especially outside specialist centres. Neuroimaging techniques using magnetic resonance (MR) can assess changes in structure, microstructure through diffusion tensor imaging and metabolism using spectroscopy and cerebral perfusion. Identification of such changes may contribute to our understanding of the disease process..
