<s>[INST] I believe that I have caught an infection that effects the nervous system. I was very mentally healthy and intelligent before this happened. I know exactly where it was caught, probably from coming in contact with infected feces. My family has a history of anyurisms. [/INST] Hello dear,Thank you for your contact to health care magic.I read and understand your concern. I am Dr Arun Tank answering your concern.Infection in the nervous system is not a simple thing. If you got this infection you won't be able to write it down this question also. So I don't think that you are having the infection in brain.But you should be investigated for the aneurysm in brain.I advice you should do brain MRI this will give a clue regarding your problem in brain.Your further management can be possible once you do MRI testing.I will be happy to answer your further concern on bit.ly/DrArun.Thank you,Dr Arun TankInfectious diseases specialist,HCM. </s>
