A medical exam is the first step to diagnose a potential brain injury. Assessment usually includes a neurological exam. This exam evaluates thinking, motor function (movement), sensory function, coordination, eye movement, and reflexes. Imaging tests, including CT scans and MRI scans, cannot detect all TBIs.
Which test is typically used to assess brain damage?
A CT (or “CAT”) scan takes X-rays from many angles to create a complete picture of the brain. It can quickly show whether the brain is bleeding or bruised or has other damage. Magnetic resonance imaging (MRI). MRI uses magnets and radio waves to produce more detailed images than CT scans.
