Leaders in neuropsychology, behavioral neurology, speech and language science, neuropsychiatry, and many other disciplines contribute to this volume, the first comprehensive review of knowledge in the field. They discuss a wide range of disorders, including areas of recent research - such as frontal lobe dementias and the neuropsychological aspects of late life depression - and clinical problems typically given insufficient consideration in other works, such as seizure disorder, head injury, and mental retardation. Normal aging is also covered in detail, and assessment procedures and clinical interventions are given thorough treatment. Other highlights include discussions of guardianship and caregiving personality and behavior, psychotic disorders, Alzheimer's, and head trauma.
