Neurocognitive Dysfunction in Head Injured Patients, Does It Reveal Various Outcomes in Both Sexes and Age-Groups?

Background: Traumatic brain injury (TBI) is one of the main causes of death and disability in both sex, young and old age group population in different countries. This study aimed to estimate effects of sex, age group and intensity level of TBI in neurocognitive dysfunction.Methods: The study was done using the mini-mental state examination (MMSE) to estimate cognitive dysfunction that directed presence to the emergency department center with medical cares in the Zahedan city. Individuals were deliberated eligible if they were 18 years of age or older. This investigation covered 6-months.Results: The sample study estimated 85 patients, 73% males with 27% females. The mean age patients reported 32.5 years (range 18-66 year) and SD (12.924) with 95% CI. Two-way between groups analysis of variance test was used to assess the impacts of sex, age and level of TBI as measured by neurocognitive dysfunction. The interaction effect between sex, age group and level of TBI was statistically significant F (0, 85) = 3.96, P = 0.01 however, the effect size was medium (partial eta squared = 0.54).Conclusion: This study supported research hypothesis that sex, age group and severity level of TBI show greater effect in neurocognitive dysfunction. In addition, the greatest amount of improvement in disability was observed among the male youngest group of survivors. These results advocate TBI survivors, especially older patients, may be candidates for neuroprotective therapies after TBI
