Classical "parietal" neglect syndrome after subcortical right frontal lobe infarction

Department of Neurology, Division of Cognitive Neuroscience, Cornell University Medical College, New York, NY.

The classical unilateral neglect syndrome is usually associated with lesions of the nondominant inferior parietal lobe. Symptoms typically include a disturbance of orienting and attending to sensory events. We examined three patients with a "parietal" neglect syndrome: CT-documented infarctions that involved only the subcortical right frontal lobe and basal ganglia. There was no CT abnormality in the nondominant parietal lobe. Our data support the view that for polymodal cortical association areas such as the parietal lobe, which connect a variety of distant cerebral areas including the frontal lobe and basal ganglia, damage in a part of the network may be associated with different aspects of the neglect syndrome.
