Neuropsychology and psychopathology: a progress report.

This paper summarizes and discusses the contributions of neuropsychological assessment to various forms of psychopathology. Emphasis is placed upon studies done with the Halstead-Reitan battery and the Wechsler Adult Intelligence Scale, but studies done with other neuropsychological test procedures are also reviewed. The conclusions reached are that neuropsychological tests are sensitive to functional regional brain disorganization in psychopathology, and that they are useful in the diagnostic process for a number of disorders including schizophrenia, psychopathy, mood disorders, and other psychiatric conditions.
