Subtle Symptoms Associated with Self-Reported Mild Head Injury

We conducted a survey on the relationship between mild head injury incidence and a variety of psychological and educational symptoms in a sample of 1,345 high school and 2,321 university students. Once figures were adjusted to represent a 50:50 gender ratio, 30% to 37% of subjects reported having experienced a head injury incident, with 12% to 15% of the total group of subjects reporting such an incident with loss of consciousness. We found significant relationships between the incidence of such mild head injury and gender, sleep difficulties, social difficulties, handedness pattern, and diagnoses of attention deficit, depression, and speech, language, and reading disorders.
