Do wizards suffer brain damage? At all? I don't think Harry has actually checked..

Bella, Voldemort, Obliviation backlash, half of St. Mungo's parents, Cruciatus... if they don't suffer brain damage, Eliezer has gone against quite a bit in canon.

I think Izeinwinter was asking whether physical damage to the brain causes mental damage in wizards, not whether there's any way to cause mental damage (where "mental damage" is distinct from "brain damage" if wizard's minds aren't actually running in their brains).

Oh. Hm... is anyone physically knocked unconscious at any point? That would seem to satisfy the criteria: a non-magical thing that affects only the physical brain but which causes negative effects on the mind.

We can find in "Quidditch Through the Ages", which can be assumed to be canon, this lovely poem:

Oh, the thrill of the chase as I soar through the air
With the Snitch up ahead and the wind in my hair
As I draw ever closer, the crowd gives a shout
But then comes a Bludger and I am knocked out.

What if Bludgers, being modelled after naive physics, have inherent knocking-people-out property? Wouldn't that be in line with how canon is being dealt with in HPMOR?

Very improbable; in Canon, they break bones in extremities all the time.

Bludgers are still magical and therefore could still "get at" the 'mind' regardless of the physical brain.
