Lewy Body Spectrum Disorders: from Dementia with Lewy Bodies to Parkinson’s Disease Dementia

Lewy body disorders are common neurodegenerative dementias and their complex features often makes it difficult to provide an accurate diagnosis. They share neuropathological and clinical features with each other as well as with Alzheimer’s disease. There have been some recent advances in biomarkers and neuroimaging, but as of yet, nothing has been conclusive when trying to identify each dementing process. Treatment options have been limited and based on small studies; however, new options are on the horizon. In this article, we will discuss recent advances in the study of Lewy body disorders and how to apply them to clinical practice. © 2016, Springer Science+Business Media New York.
