This work focuses on corticobasal degeneration (CBD), and offers assistance in diagnosing this disease. The book reviews knowledge of the pathology of CBD and examines its clinical manifestations, including apraxia, Parkinsonism, dystonia, myoclonus, alien limb syndrome, aphasia, eye movement disorders, and dementia. Noted experts define criteria for diagnosing CBD and differentiating CBD from other movement disorders or demential disorders, including Parkinson's disease, progressive supranuclear palsy, Alzheimer's disease, and Pick's disease. Consideration is given to diagnostic controversies, such as the relationship of CBD to Pick's disease. A chapter on therapy is also included.
