Objective-To determine whether older persons are at increased risk for progressive functional decline after traumatic brain injury (TBI). Design-Longitudinal cohort study. Setting-Traumatic Brain Injury Model Systems (TBIMS) rehabilitation centers.Participants-Subjects enrolled in the TBIMS national dataset. Interventions-Not applicable.Main Outcome Measures-Disability Rating Scale (DRS), FIM instrument cognitive items, and the Glasgow Outcome Scale-Extended.Results-Participants were separated into 3 age tertiles: youngest (16-26y), intermediate (27-39y), and oldest (≥40y). DRS scores were comparable across age groups at admission to a rehabilitation center. The oldest group was slightly more disabled at discharge from rehabilitation despite having less severe acute injury severity than the younger groups. While DRS scores for the 2 younger groups improved significantly from year 1 to year 5, the greatest magnitude of improvement in disability was seen among the youngest group. Additionally, after dividing patients into groups according to whether their DRS scores improved (13%), declined (10%), or remained stable (77%) over time, the likelihood of decline was found to be greater for the 2 older groups than for the youngest group. A multiple regression model demonstrated that age has a significant negative influence on DRS score 5 years post-TBI after accounting for the effects of covariates.Conclusions-This study supported our primary hypothesis that older patients show greater decline over the first 5 years after TBI than younger patients. Additionally, the greatest amount of improvement in disability was observed among the youngest group of survivors. These results suggest TBI survivors, especially older patients, may be candidates for neuroprotective therapies after TBI.Reprint requests to Ramon Diaz-Arrastia, MD, PhD, 5323 Harry Hines Blvd, Dallas, TX 75390-9036, e-mail: ramon.diazarrastia@utsouthwestern.edu.

The resulting injuries range from mild disability to longterm disabilities or death. 3 It has been observed that particular subpopulations recover differently from similar injuries. One characteristic felt to have an impact on the degree of recovery is age: in general, the older the patient the worse the outcome. 7-12 Issues of TBI and aging are important to study because of the large and growing number of older people who are affected by TBI, which has a bimodal age distribution peaking in late adolescence/early adulthood and again after age 70. 3 NIH Public AccessTBI may interact negatively with aging in at least 2 ways: (1) recovery after TBI is more limited for older than younger survivors; and (2) older individuals who have suffered a TBI are at higher risk for progressive cognitive decline. First, advanced age at the time of injury may result in less complete recovery comp...

VEEG is a useful procedure in the evaluation of TBI survivors with spells. The yield of diagnoses that may alter treatment is substantial. Additionally, mesial temporal sclerosis is associated with TBI. Given the variety of seizure types found in survivors of moderate-to-severe TBI, obtaining specific diagnosis of seizure type by VEEG monitoring impacts treatment options.

Clinical trials aimed at developing therapies for traumatic brain injury (TBI) require outcome measures that are reliable, validated, and easily administered. The most widely used of these measures, the Glasgow Outcome Scale (GOS) and the GOS-Extended (GOS-E), have been criticized as suffering from ceiling effects. In an attempt to develop a more useful and dynamic outcome measure, the Functional Status Examination (FSE) was developed, which grades outcome across 10 functional domains. The FSE has been demonstrated to be reliable and sensitive in monitoring recovery after TBI. This manuscript compares FSE with GOS-E in a cohort of patients with a wide range of injury severities. 177 individuals who survived at least 6 months after TBI were studied. The FSE and GOS-E were administered 6-12 months after injury. FSE and GOS-E scores correlated well with each other. FSE scores were distributed throughout the range, indicating that ceiling and floor effects were not present. Physiologic measures of injury severity (Glasgow Coma Score [GCS]) did not correlate with anatomic measures (Abbreviated Injury Scale [AIS] and Injury Severity Score [ISS]). GCS correlated weakly with both outcome measures, but AIS/ISS did not. We conclude that FSE and GOS-E are reliable outcome measures for TBI survivors, and FSE may offer some advantages over GOS-E due its ability to provide a more detailed description of deficits. The majority of the variance in outcome is not accounted for by currently available measures of injury severity.
