I Had A Car Accident A Year Ago And Had

I had a car accident a year ago and had a hematomia on the left side of my brain .. I have noticed over the year when ever I get any kind of headache it is in that spot on my head - should I be thinking this is causing possible memory problems - I plan to follow up with a neurologist and wanted your opinion of hematoma's .
