Suggest Remedy For Anxiety, Headaches And Nausea
Both poisoning and anxiety play a role.
Detailed Answer:
I read your question carefully and I am sorry about the issues you are experiencing.
Actually I don't think that there is no relation to the carbon monoxide exposure, it is recognized that this sort of exposure can lead to neurological impairment which can include the changes in cognitive function that you report.
However I suppose I suppose your doctors mean that these changes explain only partially those issues and some of your symptoms are related to stress and anxiety. Anxiety is a common disorder in the general population and in your case it might be triggered by the poisoning event and the life and work changes which followed its aftermath.
It is unclear what the results of your tests have been. You mention to have had convulsions while on EEG, but that should have been demonstrated on the EEG activity as well, so if the doctors didn't consider them convulsions (epileptic seizures) after the EEG exam that means that those convulsions had a psychological origin. At times seizure can be difficult to differentiate from psychogenic convulsions, but in your case if you had them under EEG it makes a clear distinction.
So if you can provide the reports of your MRI and EEG as well I might be more assured in my response. For the moment I think both the poisoning and anxiety do play a role. Unfortunately after such a long time there is not much to be done for the poisoning aftermath but anxiety symptoms can be helped by antianxiety medication which you seem to have interrupted.
I remain at your disposal for further questions.
