Table 1.
(A) Demographic characteristics. (B) Clinical characteristics. Fisher grade: 1: No SAH detected; 2: less than 1 mm thick SAH; 3: SAH thicker than 1 mm; 4: intracerebral hemorrhage or intraventricular hemorrhage with or without diffuse SAH. GCS: ≤ 8: severe head injury; 9–12: moderate head injury; 13–15: mild head injury. Complications column refers to: 0: none; 1: hydrocephalus; 2: vasospasm; 3: infarction; 4: other. C).Neuropsychological assessment. Neuropsychological results are shown in raw scores and its corresponding scaled scores (≤6 considered as impairment).
GCS: Glasgow Coma Scale; Complic: Complications; IQ: Intelligence Quotient.
