What causes brain fog for long time and unclear speech?
Patient: I have had brain fog for nearly 7 years.  I didn't quite know what it was until a friend got me to smoke weed and "relax."  I felt the exact same under the influence of the herb as I did normally, just amplified.  My speech is very impaired.  I used to have some of the best memory of all the people I knew, and now I have the worst.  I have trouble becoming angry, I usually just feel sadness.  (Which is completely different from when I was a child)  My thyroid looks normal with the exception of an elevated TSH (4.8).  Blood pressure was 110/48 and my BPM was 61.  Drinking more water raised my blood pressure, but the overall feeling stayed the same. Doctor: HiThanks for using healthcare magicIn that case, you need to consult a neurologist. It could be vascular dementia or CVA. Better to consult a neurologist. It would help to get a proper diagnosis. In case, you need further help, you can ask.Thanks
