Clinical neuropsychology is the study of the relationship between brain function on the one hand and human cognition, behavior, and emotions on the other. The field, which has grown rapidly in the past two decades, has both practical and academic applications. Practical applications include understanding more about neurological and neuropsychiatric disorders so that diagnosis, treatment, and rehabilitation of patients can be more individualized and meaningful. Ultimately, multidisciplinary efforts may help prevent the occurrence of these disorders. Academic objectives include more comprehensive investigation of how the healthy brain works by integrating information gathered from experiments using subjects with both healthy and damaged brains. Further, dissemination of this knowledge is essential. Students interested in the field of neuropsychology, as well as other health professionals, need to understand the kinds of cognitive impairments and behavioral difficulties patients experience without always needing to know in detail how to assess and rehabilitate the problems themselves.
