I am looking for some information on concussions. Say, a person is hit on the head pretty harshly, making them lose consciousness for a couple of seconds.

Could anyone tell me what the MINIMUM additional consequences would be? Could it be that this person, in an exceptional situation, would only be very dizzy and confused for a maximum of 12 hours? And might this person even be able to walk, let's say 20 kilometres, the following day if the event causing the concussion happened at around 6 in the evening (let's say 18 hours later, so at noon the following day)?

Or is the only way this person could be up and walking the next day be if he did not lose consciousness at all?

The person in question is a male 16 year old.

These questions might seem a bit odd, but unfortunately, on the internet, the only information I can find is the maximum or the average recovery time, which is not what I'm looking for right now.

Thanks in advance!

Cerebral concussion is when you don't feel OK after head injury. Loss of consciousness is not essential. You can have headache, dizziness, nausea, fatigue. You may feel perfectly fine next day or continue being dizzy for a few days. It all depends on severity of the impact. By Andre Strizhak
