Concussion vs. Contusion

A brain injury from impact versus a bruise.

The comparisoni

✗ Wrong

I have a concussion on my arm.

✓ Correct

I have a contusion on my arm — CONTUSION is the medical term for a bruise. CONCUSSION is specifically a brain injury.

The ruleii

CONCUSSION = brain. CONTUSION = bruise.

CONCUSSION is a mild traumatic brain injury — temporary disruption from impact (no visible bleed). CONTUSION is any bruise — broken capillaries causing visible discoloration. The two words sound similar; the meanings are unrelated.

Memory aidiii

Remember it like this

Concussion = head. Contusion = bruise.
