Headache attributed to idiopathic intracranial hypertension (IIH) (pseudotumor cerebri) is a secondary headache disorder. Secondary headache disorders are those that are cause by or related to another condition. In this case, the headache is secondary to IIH.

Headache attributed to IIH is often daily. It is most often a steady ache, not pulsatile, and is worsened by coughing or straining. This type of headache develops in relation to increased intracranial pressure. It improves when cerebrospinal fluid is drawn off to reduce the pressure to normal range during a lumbar puncture (spinal tap), and it stops within 72 hours of maintaining normal intracranial pressure.
