Brief Answer:
Corpus callosum is a brain structure.

Detailed Answer:
Hello and thanks for using

I have read your question and understand your concerns.

Corpus callosum is a white matter structure inside the brain that connects functionally and anatomically the two brain hemispheres.

Demyelination is the damage of the myelin ( nerves sheath ) by different conditions such multiple sclerosis, infection, etc.

Since ischemic stroke was suspected, you should continue the treatment and control your blood pressure.

Hope you found the answer helpful.

Let me know if I can assist you further.

Take care.

Hello again.

Since the headache you refer is the same as before, I think there is no need to worry about and to rush to the Doctor.

You can discuss about it when you meet the Doctor in two days.

Hope this helps.
