Is systemic arterial hypertension a risk factor for idiopathic intracranial hypertension?

The Bottom Line: Systemic arterial hypertension has been reported as occurring in 14–32% of patients. In one study, blood pressure was significantly higher in those with idiopathic intracranial hypertension than in controls. Whether this is a true disease association or simply reflects the high incidence of raised blood pressure in a population with increased bodyweight is unclear.
