Neglect can be severely disabling. Although usually contralesional, neglect can also be ipsilesional and can be spatial and/or involve the body. Spatial neglect can be horizontal, vertical, and radial. Spatial neglect can also be viewer, environmental, or object centered and can be present with spatial and personal imagery. Neglect is more often induced by right parietal and frontal than left hemisphere lesions. There are now several behavioral, stimulation, and pharmacological treatments for neglect.
