Suggest Treatment For Night Sweats And Elevated Heart Rate
No serious neurological disorder(s).
Detailed Answer:
Hello and thanks for using HCM.
I have read your question and understand your concerns.
You had CT, MRI, and MRA of the brain done that resulted in no changes to justify your symptoms, so you shouldn't worry more than necessary about any serious neurological disorder(s).
Since there are no signs of infarction or ischemia, you shouldn't worry about decreased blood flow to the cerebellum, periodic follow up is sufficient for this issue.
In the other hand, low iron may point to gastroenteric tract issues such gastritis, ulcers, etc. that may also cause low vitamin B12 in blood, electrolytes imbalance, problems with coagulation, etc.
All these conditions if confirmed may justify at least a part of your symptoms, correct diagnosis, and treatment of such conditions together with hypothyroidism should improve your symptoms too.
It is obvious that anxiety is playing an important role in your overall condition too, so, correct treatment of anxiety should lead to significant improvement.
In the other hand, healthy living and feeding, exercising is necessary to promote health.
In conclusion, I don't see any serious or not treatable condition in your case, since you had all of these tests done.
Discuss with your Doctor about above-mentioned issues.
Hope you found the answer helpful.
Let me know if I can assist you further.
In good health.
