<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a TBI and have problems with muddled thinking. I was taking my Toprol at 9 a.m. at work and at bedtime. This week I changed the time for my morning Toprol to 1 p.m. This seems to have improved my focus and concentration at work, but now I am muddled after work. Would more COQ10 andor omega369 help this? Is there anything else that might help?  <response>: Hi, Thank you for posting your query. Cognitive symptoms following traumatic brain injury TBI spontaneously improve over time. However, COQ 10 and omega 3 fatty acids may help there is no hard data in literature though regarding their efficacy. Another medication that could help you is paracetamol. I hope it helps. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly
