This book provides comprehensive coverage of speech and language disorders arising from pathological processes involving the subcortical structures of the brain. It gives an understanding of these disorders in terms of their neuropathological basis, clinical symptomatology and prognosis. A full discussion of contemporary models and theories of subcortical participation in speech and language processing is given, including discussion of the possible roles of structures such as the basal ganglia, subthalamic nucleus, thalamus and cerebellum.

The book covers speech and language disorders associated with a variety of subcortical conditions, ranging from major degenerative conditions such as Parkinsons? Disease, Huntington?s chorea and dystonia, through to acquired non-degenerative subcortical lesions arising from, for example, cerebrovascular accidents and sterotactic surgically induced lesions. In addition, a full description of the relevant assessment and treatment procedures currently recommended for use for each of the subcortical communication disorders is given.
