All recruiting trials (5)
-
Tirzepatide for Idiopathic Intracranial Hypertension
This trial tests whether tirzepatide can help people with idiopathic intracranial hypertension by comparing it to placebo over 12 months.
-
Advanced imaging techniques for understanding idiopathic intracranial hypertension
This study is testing advanced imaging techniques on patients with stubborn idiopathic intracranial hypertension to see how stenting affects their brain fluid flow and overall condition.
-
Transverse sinus stenting for people with long-term intracranial hypertension on acetazolamide
This trial will test whether adding a stent in the narrowed transverse sinus helps adults with idiopathic intracranial hypertension who have been on acetazolamide for over a year but still have symptoms.
-
Transverse sinus stenting for newly diagnosed idiopathic intracranial hypertension
This will test whether adding transverse venous sinus stenting to standard medical care helps adults with newly diagnosed idiopathic intracranial hypertension improve vision, headaches, or tinnitus.
-
Understanding the link between body mass index and treatment response in idiopathic intracranial hypertension
This study is trying to see how body weight affects treatment success in people with idiopathic intracranial hypertension and what weight goals might help them feel better.
