JAMA Network JAMA Neurology : GLP-1 Receptor Agonists in Idiopathic Intracranial Hypertension
6 snips
Jul 14, 2025 In this enlightening discussion, Dennis J. Rivet II, an esteemed neurosurgeon and researcher from Virginia Commonwealth University, dives into the intriguing world of idiopathic intracranial hypertension (IIH) and the promising role of GLP-1 receptor agonists in its treatment. He highlights the complexities surrounding IIH, including its connection to obesity and the innovative use of GLP-1s in managing symptoms while potentially reducing the need for surgeries. Rivet also emphasizes the necessity of considering BMI and metabolic health for comprehensive patient care.

IIH Demographics and Unknown Mechanism
- Idiopathic intracranial hypertension (IIH) primarily affects obese women of childbearing age, but its physiological cause remains unclear.
- Weight loss is effective for management, but hard to achieve, prompting exploration of other treatments like GLP-1 receptor agonists.
GLP-1 Receptors in Brain
- GLP-1 receptors exist in the central nervous system, notably in the choroid plexus involved with cerebrospinal fluid production.
- This suggests GLP-1 agonists may influence intracranial pressure beyond weight loss effects.
Using EHR Data For IIH Research
- Use large electronic health record databases to study rare conditions like IIH efficiently.
- Assess outcomes like symptom improvement, medication reduction, and need for surgery in observational studies.
