With my indiopathic intercranial hypertension i have all usual sx plus dizziness and lightheadedness, could a drusen cause this?

Drusen: does not cause idiopathic intracranial HTN. Dizziness and lightheadedness are not typical symptoms of pseudo-tumor. (Positional headache and blurred vision are.) Diamox, Topamax, (topiramate) Zonegran, optic nerve fenestration and elimination of causative factors are treatments. Avoid tetracycline, excessive vitamin A, lead and steroids,. Make sure you are not iron deficient or overweight.

Unrelated: Drusen are small globules of protein within the substance of the optic nerve at the disc which cause the appearance of papilledema (swelling from increased intracranial pressure) sort of like pillows piled under a sheet. They are completely unrelated to idiopathic intracranial hypertension, although you can have both simultaneously--making the optic nerve appear very enlarged.
