Dr. Elizabeth Selvin, a professor in the Department of Epidemiology at the Johns Hopkins Bloomberg School of Public Health, and colleagues recently published a letter in the New England Journal of Medicine highlighting the prevalence of self-reported head injuries.
Among their findings: “Head injury was most common among respondents with a college education (17.3% of whom reported a head injury) but also occurred at high frequency among those with lower family income (16.4 percent), as compared with respondents with other levels of education and income.” The prevalence of self-reported head injury among U.S. adults 40 years of age or older was 15.7 percent.
The letter also notes that “approximately 23 million U.S. adults 40 years of age or older reported a history of head injury with loss of consciousness. The high prevalence of head injury in the general population and its links with neurologic and psychiatric conditions suggest that research into the causes and consequences of head injury in the general population and in subgroups would be valuable.
Co-authors included Dr. Andrea L.C. Schneider of the Johns Hopkins University School of Medicine, Mr. Dan Wang, the Bloomberg School and Dr. Geoffrey Ling of Johns Hopkins School of Medicine.
