My moderate TBI was 30 years ago. I still have an irregular EEG for my left temporal (word finding) and basal frontal lobes (lost smell and taste grew back over 8 years). I still have issues finding and remembering words, especially numbers and peoples' names. Probably 80% of the recovery was in the first 1.5 years; the remaining took ~6 years. I had just completed my outline for my doctoral dissertation and went for a ride; I woke up in the ER with blood coming out of an ear. Being a scientist with a TBI is mixed in that we live in our brains, but we also know how to navigate them. Recovery from a TBI is brutal emotionally, both from ourselves and others. Be kind to yourself and know that healing occurs, but is a slow stairstep process. New learning, hobbies, and all the rehab steps are important to rewiring.
