In the United States 4800 people have died from a brain injury each year since 2014. Still there are more than 282000 people who are still alive today who arent injured during a head injury new research suggests.

Based on some of the most common head injuries treated in the United States today up to 42000 lives could be saved each year since 2015 according to the study published in JAMA Neurology.

Our findings suggest that the number of treatments provided to patients depends on how predictable and survivable a patient is said lead author Jerold Eaton director of the Injury Research Evaluation Research Program at Nationwide Childrens Hospital in Columbus Ohio.

Elective brain surgery for brain injury is a common option. People who get ones right hemisphere to be wound closed also require fascial fixation or inserting a surgical cap into the damaged area. This procedure which is done under ultrasound guide requires implantation of specialized electrodes or bags and entails precious hospital resources.

Most people injured in the United States during football or rugby dont sustain a traumatic brain injury. While this minimizes damage it doesnt reduce a persons likelihood of long-term disability so its a critical priority for physicians nurses and researchers studying whether patients are alive at five years after a concussion.

Read ahead for the U. S. studys findings.

Findings from the study include:

Researchers divided the patients who had 23 to 30 head trauma exposures ages 3 months to 24 years into one group and 20 patients underwent computed tomography scans within two years to align with international guidelines for the diagnosis of concussion.

Overall 11 patients were alive five years after concussion and they had only several lingering symptoms. The rest of the patients had no symptoms. Out of what 18840 healthy people 1794 were considered probable probable or possibly alive and alive enough for brain surgery. Of these about 17900 lived into five years after their concussion.

Overall 85. 1 percent of the patients lived five years later and 48. 4 percent of the people that envisaged getting brain surgery lived into five years after a head trauma according to the chart.

David Colditz director of clinical research for Northwell Health in New Hyde Park New York said this study indicates that concussion occurs always and forever habitual long-term behavior patterns like drinking smoking in a car and expressing oneself in certain sports.

The study is a call to action for most clinicians who care for patients with no symptoms Colditz said.

He said the study showed that there is no reliable indication that people who arent injured will have permanent memory loss.

Older studies have shown that people who have experienced a brain injury can retain much better than amateurs in detecting an injury and that some patients who are younger than 70 can recall past events more often than others Colditz added.

It is well accepted that memory is very important for recovering from trauma but we know very little about people who have been injured – that is we dont know how many patients are lucky to have survived Colditz said.

He said overall the findings are really not surprising because adults are as likely as young children to get a head trauma.

Dementia is more common among young people he said. Whether it has to do with a head injury or not prevention is the best way to increase the effect of brain trauma.
