Computed tomography correlates of chronic unilateral neglect

We assessed lesion site and size, ventricular size, and occipital width asymmetries on the computerized tomography (CT) scans of 24 patients (aged 56–80 yrs) with chronic unilateral neglect. The most common lesion site in these Ss was temporoparietal, with extension to the frontal lobe or to the thalamus being relatively uncommon. Severity of neglect correlated significantly with the size of the lesion but not with that of the ventricular system. No correlation between severity of neglect and lesion size was found in a subgroup of Ss after rehabilitation training. The pattern of occipital asymmetry was normal. CT scan data do not appear to be particularly helpful in predicting severity and duration of unilateral neglect or response to rehabilitation training.
