Brief Answer:
Detailed medical examination and brain MRI are necessary for the diagnosis.

Detailed Answer:
hello and thanks for your questions here at the "Ask a Doctor" service.

I have read your question, I saw the reports that you uploaded too.

First is necessary to provide more information about your friend's complaints and medical history.

Uploaded reports show an EEG and a prescription.

The EEG shows some asymmetry in the brain's electrical waves but is not specific for the etiology of the headaches.

In my opinion, there is a need for imaging of your friend's head and brain for a correct diagnosis, together with a detailed clinical examination by a Neurologist.

I hope you found the answer helpful.

Let me know if I can assist you further.
