I was first diagnosed with tick borne encephalitis in 2009. Still get sick all the time. Now have brain damage as a result of the infection.?

Sorry to hear that. Unfortunately, encephalitis contracted from any source (ticks, mosquitos, etc.) can result in neurological dysfunction. If you were treated for the appropriate tick illness, there should not be any remaining infective agent, but it is possible that your immune system may be slightly disrupted. See you doctor for a reevaluation.
