Neglect following damage to frontal lobe or basal ganglia

Abstract Though neglect is often thought to be a sign of parietal lobe damage, particularly of the non-dominant hemisphere, there is evidence that lesions in the frontal lobes and in the basal ganglia can produce neglect also. We present five patients, with lesions in both the mesial and dorsolateral aspects of the frontal lobe, and in the basal ganglia, as examples of “non-parietal” neglect. It is possible that all of these structures belong to an anatomically inter-connected system subserving selective attention and that lesions in each of the components are capable of producing neglect although with slightly different characteristics.
