Thank you. I prefer the term cognitive impairments to brain fog because fog usually goes away eventually but these impairments often don’t. I knew one person with MdDS who was working in the American military and got triggered by a blast during training. He had a terrible time in his unit with people accusing him of faking symptoms to get out of training and active duty and of being a coward. Thankfully he got a new commanding officer who had training in physiotherapy and got him accurately diagnosed and treated very quickly and although he hasn’t been able to return to active duty he now works with army and navy veterans with similar injuries and in suicide prevention in this population. One paper I cite a lot which might be of interest to you is this UK paper Smith RM, Burgess C, Tahtis V, et al

Why are patients with acute traumatic brain injury not routinely assessed or treated for vestibular dysfunction in the UK? A qualitative study

BMJ Open 2023;13:e067967. doi: 10.1136/bmjopen-2022-067967 which had very good patient/public involvement and I’m pleased to say that there has been an improvement in screening since it was published although not as much as we need here.
