Hi,
Thank you for posting your query.
Your symptoms need to be evaluated by a
neurologist in order to make a diagnosis.
Normal scans is a good news.
Many times, the abnormality is due to abnormal chemicals (
neurotransmitters) in the brain, which would not show up on CT or
MRI scan. Most often, a clinical diagnosis can be made on the basis of clinical examination. In some cases, blood tests and PET scan may help.
I hope my answer helps. Please get back if you require any additional information.
Wishing you good health,
