In adults with severe diffuse traumatic brain injury and refractory intracranial hypertension, early bifrontotemporoparietal decompressive craniectomy decreased intracranial pressure and the length of stay in the ICU but was associated with more unfavorable outcomes. (Funded by the National Health and Medical Research Council of Australia and others; DECRA Australian Clinical Trials Registry number, ACTRN012605000009617.).
This study aimed to investigate outcome in adults with mild traumatic brain injury (TBI) at 1 week and 3 months postinjury and to identify factors associated with persisting problems. A total of 84 adults with mild TBI were compared with 53 adults with other minor injuries as controls in terms of postconcussional symptomatology, behavior, and cognitive performance at 1 week and 3 months postinjury. At 1 week postinjury, adults with mild TBI were reporting symptoms, particularly headaches, dizziness, fatigue, visual disturbance, and memory difficulties. They exhibited slowing of information processing on neuropsychological measures, namely the WAIS–R Digit Symbol subtest and the Speed of Comprehension Test. By 3 months postinjury, the symptoms reported at 1 week had largely resolved, and no impairments were evident on neuropsychological measures. However, there was a subgroup of 24% of participants who were still suffering many symptoms, who were highly distressed, and whose lives were still significantly disrupted. These individuals did not have longer posttraumatic amnesia (PTA) duration. They were more likely to have a history of previous head injury, neurological or psychiatric problems, to be students, females, and to have been injured in a motor vehicle accident. The majority were showing significant levels of psychopathology. A range of factors, other than those directly reflecting the severity of injury, appear to be associated with outcome following mild TBI. (JINS, 2000, 6, 568–579.)
The deleterious consequences of traumatic brain injury (TBI) impair capacity to return to many avenues of pre-morbid life. However, there has been limited longitudinal research examining outcome beyond five years post-injury. The aim of this study was to examine aspects of function, previously shown to be affected following TBI, over a span of 10 years. One hundred and forty one patients with TBI were assessed at two, five, and 10 years post-injury using the Structured Outcome Questionnaire. Fatigue and balance problems were the most common neurological symptoms, with reported rates decreasing only slightly during the 10-year period. Mobility outcomes were good in more than 75% of patients, with few participants requiring aids for mobility. Changes in cognitive, communication, behavioral, and emotional functions were reported by approximately 60% of the sample at all time points. Levels of independence in activities of daily living were high during the 10-year period, and as many as 70% of subjects returned to driving. Nevertheless, approximately 40% of patients required more support than before their injury. Only half the sample returned to previous leisure activities and fewer than half were employed at each assessment time post-injury. Although marital status remained stable over time, approximately 30% of participants reported difficulties in personal relationships. Older age at injury did not substantially alter the pattern of changes over time, except in employment. Overall, problems that were evident at two years post-injury persisted until 10 years post-injury. The importance of these findings is discussed with reference to rehabilitation programs.
