I'm 84. I got peripheral neuropathy from chemo for brain cancer at 79. I take gabapentin 2 to 3 times a day. I take 300 mg. each time. It actually gives me a little high. I recently had my yearly check up. My BP was 98/60. My EEG showed no skips at all. I can run if I have to in an emergency. My brain seems fine. I've had no problems with taking gabapentin.
