Conversation: The conversation between human and AI assistant.
[|Human|] I have a friend of my family who was in a car accident in October. He hit the right side of his head but did not sustain head trauma. He had multiple tests done including a MRI and MRa and CT scan . Initally the Doctor said they saw an anurism on the left side of the frontal lobe . Then another test was done and they said there was nothing. He has been to a neurologist and was given seizure medication. He is 16 and is now suffering from migraines on the left side and when the migraine comes on his pupil get very big. He and his family on scared and getting no answers.
[|AI|]  Hi, Thank you for posting your query. First, we need to resolve whether your friend has an aneurysm. This can be done with the help of cerebral angiogram. If it has not been done, please get it done after discussing with his neurologist. Regarding his repeated headaches, if his brain scans are normal, then most likely it is due to migraine. He can be started on preventive medications such as topiramate or divalproex to prevent repeated headaches. Best wishes, Chat Doctor.
