Hi, I've had two concussions in four months. One with loss of consciousness for a few minutes and the other without. I went into a major depression afterwards, two months in, my phyciatrist diagnosed me with frontal lobe disorder. It has mildly affected my speech and balance but is getting better. He told me at this point to get an mri the damage would be microscopic in size. What are your thoughts is this necessary or not? Thank you
