The aim of this study was to evaluate the correlation between unilateral spatial neglect (USN) and neurological deficits, site of lesion by CT scan, and activities of daily living (ADL) at discharge.Thirty-eight right-handed patients with right hypertensive intracerebral hemorrhage (putamen 21, thalamus 17) were examined for neurological and neuropsychological deficits in addition to USN and performed CT scan. USN was revealed in 27 (76.8%) in which, 17 cases were putaminal hemorrhage and the other were thalamic hemorrhage.The patients were subdivided into 3 groups of USN; ie, without USN, transient USN and persistent USN.In the putaminal hemorrhage, the presence and persistence of USN seemed to be largely dependent on the size of hematoma. Four of 7 cases who showed the hematoma volume larger than 40ml revealed persistent USN and other 3 cases with younger than 50 years old showed transient USN. No cases with hematoma smaller than 20ml revealed USN.In the thalamic hemorrhage, the size of hematoma had no relation to the presence of USN. All of the USN caused by thalamic hemorrhage was transient.The presence of USN is an important factor determining patients' ADL. Therefore it is important to recognize USN on initial evaluation.
