RIGHT-SIDE NEGLECT IN ALZHEIMERS-DISEASE

Unilateral neglect-the inability to pay attention to events occurring on one side of space-usually occurs for left-side events after focal r ight-hemisphere damage. We report a 73-year-old woman with probable AD and no evidence of focal brain lesions who showed signs of right-side neglect and extinction. Neglect was more severe after 1 year. Neuroim aging techniques demonstrated an asymmetry of cortical involvement, wi th cortical atrophy and hypoperfusion predominant in the left posterio r regions. Unilateral neglect should be assessed systematically in AD.
