King-Devick Test

The King-Devick Test is a quick, simple assessment that measures rapid eye movement, attention, and information processing speed. During the test, a person reads aloud a series of numbers from cards or a screen as fast and accurately as possible. It’s often used to help detect issues related to brain function or concussions, as changes in performance can indicate problems with brain health or recovery. The test provides immediate results, making it a useful tool for sports, clinics, and hospitals to assess neurological status efficiently.
