### input:
I was in a car accident on July 14, 2014. I hit my head but was only out for maybe a minute or so. I experienced head pain but didn t think much of it. Since then I have been gradually having memory problems, trouble concentrating, and staying focused. Also there is frequent dizziness, nausea, and head pain. My Doctor ordered a MRI last week. It revealed the volume of the brain is normal. There is minimal retained fluid within the mastoid air cells consistent with mild chronic mastoiditis. There are mild inflammatory changes involiving the ethmoid and frontal sinuses. There are afew small discrete nonspecific high signal intensity foci within the juxtacortical and periventricular white matter of both cerebral hemispheres on the T2-weighted anf FLAIR pulse sequences. There is no transependymal spread of CSF. We have not discussed these results yet. Could I be dealing with a TBI?

### output:

Hi, Thanks for writing in. It is possible that you had a mild brain injury and this caused you to lose consciousness for about minute. Non-specific white matter high signal areas on FLAIR can be due to many causes and if you do not have any other symptoms other than dizziness and poor memory then most likely it is due to the head injury on 14th July 2014. Since the brain volume is normal, it is unlikely to be a serious injury that you had. Mild brain trauma can cause memory problems and dizziness for a while. I suggest you attend neurological rehabilitation services at the hospital you attend and discuss your problems. There are many brain training exercises which can help you with your memory. The chronic mastitis is a concern because it shows a possible ear infection and if not treated in earlier stages, this can cause problems related to hearing and also spread to the brain.
