What are some tests that evaluate concussions?

Tests that help evaluate concussions include imaging tests, such as CT scans, and cognitive tests, according to Mayo Clinic. A neurological examination may help evaluate coordination, balance, vision, hearing, reflexes and sensation. Overnight observation in the hospital may help provide diagnosis as well.

Cranial CT scans and MRIs may help determine the severity of brain injury and identify a swollen or bleeding skull, as Mayo Clinic explains. Cognitive tests aid in evaluating concentration and memory recall. A person who experiences loss of consciousness, headache or dizziness after injuring the head or other parts of the upper body should seek medical attention.
