Diagnosing a concussion is something that is often difficult. Researchers have been trying to determine ways to diagnose concussions without having to rely on guesswork. One new development is showing some promise for this.
Research suggests that an auditory biological marker can help doctors to diagnose a concussion. The study included 40 children who were diagnosed with a concussion and were being treated for it. A control group of children were also included. On average, the children with concussions had a 35 percent reduction in the frequency response to certain audio signals. This was determined by using three sensors on each child's head.
The auditory biomarker allowed researchers to successfully identify 95 percent of the control group and 90 percent of the children who suffered from a concussion. It is important to note that the sound processing changes weren't global. The children in the group only had altered processing of specific sounds and pitches.
The study didn't note whether this biomarker would help to diagnose adults who suffered from a concussion. If it does, it could be a huge step forward for patients who are often left in limbo about whether they have suffered a concussion or not.
Patients who do suffer a concussion might need long-term care. In some cases, such as when a person suffers repeated concussions, there are life-long effects that might manifest. In all of these cases, getting proper medical care is necessary. This medical care comes at a cost, so people who suffered a brain injury in an accident might opt to seek compensation from the person who was liable for the accident.
