Make sure your physician is evaluating and treating your Lyme. Lyme is relatively uncommon in the Southeast US compared to the Northeast US so physicians here are not as experienced in treating it.
I would also seek a second opinion from a neurologist if you have not already. If you feel that you have cognitive impairment now, then the neurologist may feel that a brain MRI is indicated. This may not affect management, but may provide you with prognostic information.
