Several studies have found that Alzheimer’s disease is more common among individuals who have sustained a severe head injury (accompanied by loss of consciousness) during the course of their lives. What remains unclear is whether head trauma is a result of falls during the early stages of Alzheimer’s or whether Alzheimer’s results from an earlier head trauma. Additional research is necessary to fully understand the association between Alzheimer’s disease and head injury.
