Hi bucci,
Were you ever tested for lyme? IgeneX is the most accurate lab we have in the U.S.:
www.igeneX.com
If you were not tested, you can order a free testing kit from IgeneX but you will need a doctor's signature for the actual bloodwork.
I don't believe anyone's brain gets damaged from lyme yet lyme does cause brain fog, loss of memory, lyme rage episodes, etc. but all those symptoms can be temporary if one is taking the right supplements to clear out the toxins.
