A study conducted by British researchers has added new fuel to concerns that head injuries might be the source of signs of premature aging in the brains of victims, a finding that may have implications for personal injury cases in Wisconsin. The researchers examined brain scans from 99 people who had suffered traumas arising from falls, assaults and motor vehicle accidents, including scans from periods of one month to 46 years following the traumatic events. The researchers noticed that signs of inflammation and impairment appeared in some victims many years after the initial cause of the injuries.
A traumatic brain injury may result from a variety of causes. The aftermath of brain trauma may include permanent disability or a prolonged coma. The medical expenses, therapy, rehabilitation and long-term care needed to care for a person with brain damage can be considerable. These traumas are a major cause of death and disability in Wisconsin and across the U.S., contributing to nearly 30 percent of deaths caused by injuries.
