Hi,
Thank you for posting your query.
First of all, I would like to reassure you that your son's symptoms are not suggestive of any thing serious, as MR angiogram and CT angiogram are within normal limits. This has excluded
vasculitis or
brain ischemia (lack of blood flow to brain) as cause for his symptoms.
He needs treatment with good anti-migraine medications such as
topiramate or
divalproex. For acute relief, he can use
rizatriptan tablets.
I hope it helps. Please get back if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
