This "Compendium" is a comprehensive reference manual containing an extensive selection of instruments developed to measure signs and symptoms commonly encountered in neurological conditions, both progressive and non-progressive. It provides a repository of established instruments, as well as newly-developed scales, and covers all aspects of the functional consequences of acquired brain impairment. In particular, the text provides a detailed review of approximately 150 specialist instruments for the assessment of people with neurological conditions such as dementia, multiple sclerosis, stroke and traumatic brain injury. Part A presents scales examining body functions, including consciousness and orientation; general and specific cognitive functions; regulation of behaviour, thought, and emotion; and motor-sensory functions. Part B reviews scales of daily living activities and community participation. Part C focuses on contextual factors, specifically environmental issues, and Part D contains multidimensional and quality of life instruments. Each instrument is described in a stand-alone report using a uniform format. A brief history of the instrument's development is provided, along with a description of item content and administration/scoring procedures. Psychometric properties are reviewed and a critical commentary is provided. Key references are cited and in most cases the actual scale is included, giving the reader easy access to the instrument. The structure of the book directly maps onto the taxonomy of the influential International Classification of Functioning, Disability and Health (World Health Organization, 2001), enabling linkage of clinical concepts across health conditions. The "Compendium" will be a valuable reference for clinicians, researchers, educators, and graduate students, and a practical resource for those involved in the assessment of people with brain impairment.
