Temp. brain trauma: Hi Sadie, Even if you did not have a traumatic brain injury, your brain could have sustained some bruising or irritation that can cause temporary symptoms like mild brain trauma. I once worked with a girl sophomore college student with a similar story who took medical leave until her temporary condition resolved. Have a neurologist follow you until you're 100%.
