What are the tests for concussion?

Interview,talking. Often the concussed will answer questions in a way that helps you to know they have a concussion.Ask about where they are, who you are, where they are, what day it is etc.You will be surprised in how messed up the concussed person is in the immediate injury period.
COBCUSSION. Typically a combination of following symptoms and their resolution along with data from repeated neurocognitive testing.
ImPACT test. Besides a good history and physical exam, there are several validated, proven to be effective neurocognitive exams. I am familiar with the impact test that measures a number of brain functions. When compared to a baseline exam, it is probably the most accurate test out there for diagnosis and mon iytering improvements.Blood and imaging tests are usually worthless.
