Loss of Consciousness
Some people with a concussion would lose their consciousness. However, not everyone experiences this symptom. When there is direct contact between your head and the cause, your brain will be negatively affected. This leads to some damages to your cognitive system, which eventually results in lost consciousness. Indeed, it is the most obvious symptom that you are experiencing a concussion. Thus, if you notice a person that blacks out after a hit or blow to his or her head, make sure to seek medical emergency for early treatments. [2]
