Abstract:
The diagnosis of post-concussion symptoms (PCS) has been a controversial issue because of that its pathogenesis is often involved in both neural damage and psychosocial factors. Recent researches have examined the diagnostic and evaluating value of several available methods or tools, including clinical interview, conventional CT and magnetic resonance imaging (MRI), neuropsychologic testing and neurochemical test. In mild traumatic brain injury (MTBI), there exist diffusive damages to white matter distributed particularly near the gray matter-white matter boundary and in the long white-matter tracts in midline structures. The conventional imaging techniques are unable to detect any positive evidence due to the diffusive nature of these injuries. This paper is to review epidemiologic study, diagnostic criteria and relevant disputes, conventional diagnostic strategy and new MRI techniques, and then evaluate the application and prospective value of them in the diagnosis and rating of PCS and MTBI. Non-invasively quantitative assessments of modern brain imaging technique may be developed to sensitive and promising tools in the diagnosis and forensic evaluation of PCS.
