[P1-211] Unilateral Spatial Neglect in Children with Cerebrovascular Disorders
[Introduction] Unilateral spatial neglect is a symptom characterized by failure to notice, react to, or orient to stimuli to the hemisphere contralateral to the lesion. Recent advances of imaging diagnosis reveal foci in regions other than the parietal lobe. However, there are very few reports involving children. We report a retrospective study of unilateral spatial neglect in children with cerebrovascular disorders. [Patients and Methods] Fifty-seven patients under 15 years of age with cerebrovascular disorders (excluding brain stem and cerebellar hemorrhage) who underwent inpatient rehabilitation in our hospital during the period from April 2001 to October 2015 were investigated. The following items were investigated: 1) unilateral spatial neglect 2) intelligence or developmental quotient, 3) brain MRI and ECD-SPECT findings of parietal lobe lesions, 4) attention deficit, and 5) aphasia in the case of right unilateral spatial neglect. [Results] Four patients showed left unilateral spatial neglect (23.5% of left hemiplegic patients), 11 right unilateral spatial neglect (28.2% of right hemiplegic patients). No significant difference in intelligence quotient, parietal lobe lesion, and attention deficit were noted between the presence versus the absence of left and right unilateral spatial neglect. Between right unilateral spatial neglect and aphasia were similarly investigated but no correlations were detected. [Discussion] The incidence of unilateral spatial neglect in children was lower than that in adults (the incidence of left unilateral spatial neglect in adults is approximately 40%). The responsible lesions of unilateral spatial neglect were not only parietal lobe lesions in children similar to adults.
