Part of the Critical Issues in Neuropsychology book series (CINP)


Neuropsychologists frequently work with patients who have specified brain lesions that produce well-documented cognitive or behavioral effects. However, for those clinicians working with children or adolescents who suffer developmental disorders, the pathogenesis of cognitive and behavioral deficits may be poorly understood. This chapter reviews the anomalies of neurological development that not infrequently are seen in children and adolescents with developmental disorders. Most typically the neuropsychological manifestations of these anomalies impact on widely distributed functional systems, thus producing generalized and severe impairment. However, there are exceptions, especially with regard to anomalies of neuronal migration. Some basic understanding of these effects should aid neuropsychologists in a better conceptualization of how disorders of neurological development produce different effects than do discrete lesions of the central nervous system.
