According to new research, adults who suffer from any type of head injury The death rate during the 30-year study period was double that of those who did not, and the death rate was nearly three times higher among those with moderate or severe head injuries.
The results of the study were published in JAMA Neurology.
In the United States, more than 23 million adults age 40 and older report a history of head injury with loss of consciousness. A head injury can be attributed to many causes, from motor vehicle accidents, unintentional falls, or sports injuries. Moreover, there is a head injury. Linked to several long-term health conditionsincluding disability, late-onset epilepsy, dementia, and stroke.
Previous studies have shown increased short-term mortality associated with head injuries, primarily in hospitalized patients. This longitudinal study examined 30 years of data on more than 13,000 community-dwelling participants (those not hospitalized or living in nursing home facilities) to determine whether head Injury has long-term effects on mortality in adults. The investigators found that 18.4 percent of participants reported one or more head injuries during the study period, and of those who did have a head injury, 12.4 percent were rated as moderate or severe. The median time between head injury and death was 4.7 years.
Death from all causes was recorded in 64.6% of those with head injury, and 54.6% of those with no head injury. After accounting for participant characteristics, the investigators found that all-cause mortality among participants with a head injury was 2.21 times higher than the mortality rate among those without a head injury. Moreover, the death rate among people with severe head injuries was 2.87 times the death rate among people with no head injuries.
“Our data show that head injury is also associated with increased long-term mortality. This is particularly true for individuals with multiple or severe head injuries,” study lead author Dr. The author, Holly Elser, MD, PhD, MPH, a neurology resident, explained. “This highlights the importance of safety measures, such as wearing helmets and seat belts, to prevent head injuries,” Penn said.
The investigators also reviewed data for specific causes of death in all participants. Overall, the most common causes of death were cancer, heart disease, and neurological disorders (including dementia, epilepsy, and stroke). Among those with head injuries, neurological disorders and deaths due to unintentional injury or trauma (such as falls) occurred more frequently.
When the investigators examined specific neurological causes of death in participants with head injuries, they found that nearly two-thirds of neurological causes of death were attributed to neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease. These diseases make up a larger proportion of overall deaths among those with head injuries (14.2 percent) than among those with head injuries (6.6 percent).
“The data from the study do not explain why people with head injuries are more likely to die from neurodegenerative diseases, given the association between these disorders, head injury and death,” said Andrea L.C. Emphasizes the need for more research into the relationship.” Schneider, MD, PhD, assistant professor of neurology at Penn.
