Mild head trauma. Late evaluation of quality of life and neuropsychological changes

by de Almeida, Daniela Paoli

Abstract (Summary)
Mild head trauma (MHT) is defined as a transitory neurological deficit that happens after the trauma and includes a history of nausea, vomiting, headache or dizziness and loss or alteration of consciousness (less than 15 minutes), post-trauma amnesia, and Glasgow Coma Scale (GCS) at admission between 13 and 15. Despite the high survival rates, some morbidity has been observed in the three month period after this trauma. Approximately 18% of head trauma patients develop at least one psychiatric syndrome in the first year after the accident. The diagnostics difficulty and the risks of complications after the MHT continue to be a relevant problem at the emergency departments around the world. Limitations of active participation in daily life are alterations that influence life quality. Several of these alterations may be diagnosed through Interview Instruments. Our study was divided in two phases. In the first phase, 50 MHT patients admitted at Hospital João XXIII, Belo Horizonte-MG, Brazil, had protein S100B dosing and head CT taken at admission. Concentration values of S100B lower than 0.01 g/l were considered negative once this was the lowest value found in patients who did not show brain injuty signs in the CT scan. In that study it was found that protein S100B has 100% negative predictive value. In this second phase of the study, 18 months after the trauma, these patients were contacted at their homes and asked to answer four self- assessment questionnaires: two for quality of life diagnostic - World Health Organizations WHOQOL-100 and the Short Form-36 (SF36); one for the analysis of anxiety and depression - Hospital anxiety and depression scale-HADS; and one instrument developed by the author based on the Rivermead Post Concussion Questionnaire to evaluate the presence of post-concussion syndrome signs and symptoms. Several socio-demographic aspects were also analyzed, including income, source of income, means of transportation used, etc. The same questionnaires were filled by a control group formed necessarily by patients co-inhabitants, with no history of head trauma of any severity, and with closest age as possible to the patients. In the WHOQOL assessment patients showed a lower quality of life in the independence, environment, as well as in the total domains (p< 0,05). In the SF 36 assessment patients showed a lower quality of life in the functional capacity, vitality, and mental health domains (p<0,001); and also in pain, general health situation, and mental aspects (p<0,05). Patients showed more anxiety and, in the HADS Scale, showed at least a level higher, on average, than their controls. Patients also showed a higher number of post-concussion signs and symptoms than their respective controls. We did not find correlation between the later quality of life and protein S100B dosing at admission. We were not able to find correlation between the protein concentrations with the presence of brain lesions in the CCT scans taken at patients admission in the emergency department
