The following is needed for the diagnosis of a concussion:
Neurological exam. A doctor will perform an in-office exam that tests the patient’s neurological function. This exam will include tests of reflexes, balance, strength, coordination, vision, and hearing. The exam may also include tests of memory, concentration, and cognition.
Imaging tests. In cases where symptoms such as headache or vomiting are severe, or when symptoms seem to be getting worse, a doctor may want to perform imaging tests to rule out a more severe brain injury that has caused bleeding or swelling in the brain.
