4 y/o tbi hx. just had an eeg that reported "intermittent left temporal slowing". my questions are: should i be worried about driving; what would i look for in a 3t mri in light of the eeg; & what should i be discussing with my neuro-np?

Your EEG shows focal pathology over left side, which would not be uncommon as a consequence of a TBI. Question here is whether you are actually having seizure activity, which you do not address. If so, do not drive! Not clear why MRI is critical in view of a 4 year history. Have no clue what you would communicate to your NP, but maybe best to handle all of this on our virtual consult paid site
