Research on sports concussion has contributed significantly to our knowledge on the characteristics and course of recovery from mild traumatic brain injury (MTBI). Findings from research studies on injured athletes indicate that most symptoms of concussion resolve within 7-10 days of the injury. Results from studies examining the development of more persistent symptoms have found relationships with a number of psychological factors, including expectation and maladaptive coping styles. Systematic reviews of intervention strategies have indicated that psychological approaches to treatment of MTBI, such as early education and support, are more effective than any form of drug treatment. Psychologists should be aware of these findings and the potential for playing a significant role in treating individuals with MTBI. (journal abstract)

The ecological validity of neuropsychological instruments has become an important topic in recent decades, as neuropsychologists are asked to address real-world outcomes with increasing frequency. Although novel instruments that tap skills required for everyday functioning have been developed, it is unclear whether these instruments are migrating from research laboratories into the applied settings of clinical neuropsychologists. The current study surveyed assessment practices of neuropsychologists with regard to their utilization of instruments designed with ecological concerns in mind. Respondents included 747 North American, doctorate-level psychologists (40% usable response rate) affiliated with Division 40 of the American Psychological Association, National Academy of Neuropsychology, or the International Neuropsychological Society. Results indicated that approximately one-third of respondents reported use of ecologically oriented instruments (EOIs), and these instruments were generally utilized with much less frequency than traditional measures. Additionally, certain practice demographics affected usage rates of EOIs. Study findings are interpreted in the context of a growing body of literature that calls attention to the importance of developing and utilizing instruments that are able to handle the complex, real-world issues increasingly addressed during the neuropsychological assessment process

BACKGROUND:Surgery for intractable temporal lobe epilepsy usually controls seizures and improves health-related quality of life (HRQOL), but some patients experience continued seizures, memory decline, or both. The relative impact of these unfavorable outcomes on HRQOL has not been described. METHODS:We studied seizure control, memory change, and HRQOL among 138 patients in the Multicenter Study of Epilepsy Surgery (MSES), an ongoing, prospective study of epilepsy surgery outcomes. Seizure remission at 2 years and 5 years was prospectively determined based upon regularly scheduled follow-up calls to study patients throughout the follow-up period. HRQOL was assessed annually using the Quality of Life in Epilepsy Inventory (QOLIE-89). Memory decline was determined by change in verbal delayed recall from baseline to the 2- or 5-year follow-up. RESULTS:HRQOL improved in patients who were in remission at the 2-year or 5-year follow-up, regardless of memory outcome. Among those not in remission at both 2 and 5 years (25/138, 18%), HRQOL remained stable when memory did not decline (14/138, 10%), but HRQOL declined when memory did decline (11/138, 8%). These 11 patients had baseline characteristics predictive of poor seizure or memory outcome. Declines were most apparent on HRQOL subscales assessing memory, role limitations, and limitations in work, driving, and social activities. CONCLUSIONS:After temporal resection, health-related quality of life (HRQOL) improves or remains stable in seizure-free patients despite memory decline, but HRQOL declines when persistent seizures are accompanied by memory decline. These results may be useful in presurgical counseling and identifying patients at risk for poor psychosocial outcome following surgery.
