Movement disorders in Alzheimer's disease

Abstract

Movement disorders are a frequent fi nding in AD and an important issue for differential diagnosis especially with diffuse Lewy body dementia and Creutzfeldt-Jakob disease. Temporal occurrence through the evolution of the disease and severity are crucial for differential diagnosis. In addition, psychiatric complications of AD either itself or due to the use of neuroleptics represent another source of motor symptoms. In this chapter, we will review mainly those movement disorders resulting from the neurodegenerative process.
