This book is the first to provide comprehensive coverage of the communication impairments that occur in association with multiple sclerosis. It covers not only the more widely recognised motor speech disorders seen in association with this condition, but also the more recently identified language disorders reported to occur in persons with diseases of the cerebral white matter. A full description of the neuropathophysiology, epidemiology, aetiology, clinical manifestations and medical treatment of multiple sclerosis is also included.
