In the cold heart of winter in Turku, Finland, a seemingly ordinary incident paints a stark picture of a global challenge. A jogger, battling the icy conditions, suddenly slips on a sidewalk and takes a blow to the head, causing a brief loss of consciousness. At the local hospital, an MRI reveals no immediate signs of brain injury, leading to the decision to discharge the apparently "healthy" patient. However, a subsequent test by Medicortex unveils a different story. Upon analyzing biomarkers from the patient s urine and saliva, alarming levels akin to those of confirmed Traumatic Brain Injury (TBI) patients are discovered.
