I'm sorry that your question has gone unanswered for so long. It appears that you have had much work up and evaluation by your medical doctors so far . You indicate seeing mutplie providers but I dontvknow the detailed aspects of testing that you may have had done .
I think that you describe a concerning change in your self observation of your cognitive function. This change could be of a psychiatric origin or it could be of a central nervous system disease or metabolic as possibilities .....
So I would advise that you continue to seek follow up with mainly 2 specialties A) a neurologist and B) a psychiatrist
Your work up may include if you have not had already
---MRI of brain
---lumbar puncture to look for evidence of any inflammatory or infection or demyelinating problems
---metabolic tests included in your blood work to include B12 and thyroid function--- liver and renal functions and electrolytes
---toxin exposures should be considered in context of your work and hobbies ( heavy metals and pesticides as example )
--- psychometric testing to screen for mental illness such as depression / anxiety / bipolar disorders etc...
--- consider possible infections as possible cause of mental for to encephalopathy ( mono/ HSV 1/ Lyme disease/etc)
I hope that this information is helpful for you Let me know if I may be of further help.If my answers have been helpful and to your satisfaction then please remember to leave positive feedback Thank you and Best Regards,
