[|Human|] My husband can t focus and is having trouble functioning and concentrating. He has a stent, is taking aspirin and thyroid medication. He has a ringing in his head that sometimes causes dizziness. He s been to his doctor and yesterday the emergency room. They did a CT of his head and found everything normal . His blood work is normal, a chest X-ray was normal but he is laying on the floor and I just don t know what to do. I m using his email address.
[|AI|]  Hello! I understand your concern. In my opinion he should have thyroid hormones' analysis. Difficulty in concentrating is a common feature in thyroid hormones' disbalance. A stroke has been ruled out, so you should not worry. I would also recommend a cervical vessel ultrasound to see the blood flow to the brain. He has a stent and this means that other vessels must be checked for narrowing. These symptoms can also be caused by low blood flow to the brain because a carotid or vertebral stenosis. Although these disorders cause much more problems than just difficulty in concentrating and dizziness. Hope to have been helpful! Thank you for using Chat Doctor!
