Sorry to hear about the neurotoxicity. I had CAR-T to remission about 18 months ago. I had a full body rash about 12 months ago. After biopsy, they couldn't pin it down to CAR-T as a cause. I think there is high probability that this was the cause as I have never had that sort of thing before. I am 76. My immune system has not completely returned. My immunoglobulins are quite low and so are my red counts and hemoglobin. Having said that, my wife passed on a flu bug to me in the spring and we both recovered at the same time. So maybe these are just numbers. Other than that I am doing very well - golfing, gardening, camping. I do stay away from crowds, however, and still wear a mask when shopping. Hope the neurotoxicity is short lived. Best wishes! And remember: positivity is the best therapy.
