In the event of a Severe Brain Injury (Traumatic Brain Injury) the doctors may ordered a Cat Scan or MRI to analyze if there is bleeding in the brain.
The symptoms of Severe Head Injury are clear:
Confusion, drowsiness, vomiting, balance problems
The vast majority of brain injuries (about 90%) do not result in a bleeding, so a CAT Scan or MRI are not useful.
The diagnosis of a Mild TBI, called Concussion. is made of symptoms that can be subtle which may manifest in the next hour, or few days later or even weeks later.
Physical symptoms: headache, nausea, balance, dizziness
Cognitive symptoms: difficulty concentrating or remembering
Emotional symptoms; irritability, sadness
Maintenance functions: sleep disturbances, changes in appetite or energy levels
