Objective– To determine whether neuropsychological outcome is related to cerebral blood flow (CBF) early in the recovery phase. Material and methods – Twelve consecutive patients (mean age of 30 years, range 15–48 years) with severe traumatic brain injuries were subjected to a neuropsychological test battery at admission to the rehabilitation unit and after 3, 6 and 12 months. CBF measurements were performed at admission and 6 and 12 months later with a high‐resolution, two‐dimensional regional cerebral blood flow system with 254 stationary detectors after 1 min of 133 Xe inhalation (70–100 MBq/l). Results and conclusion – Mean CBF values were within normal range already in the early post‐acute phase and remained virtually unchanged during the first year of rehabilitation. A correlation was found between the individual CBF level and neuropsychological outcome 1 year after injury, particularly with regard to verbal memory capacity, reasoning capacity, and information processing speed.
