From the Guidelines

The primary treatment for symptoms of Idiopathic Intracranial Hypertension (IIH) is weight loss, which reduces intracranial pressure and has been shown to be effective in improving papilledema and headaches. According to the consensus guidelines on management of IIH 1, weight loss is a key principle of management, and a 5-10% reduction in body weight can significantly improve symptoms.

Management Principles

  • Weight loss reduces ICP and has been shown to be effective in improving papilledema and headaches 1
  • Protect the vision
  • Minimise the headache morbidity For headache management, short-term painkillers such as non-steroidal anti-inflammatory drugs (NSAIDs) or paracetamol may be helpful in the first few weeks following diagnosis, with indomethacin having some advantage due to its effect of reducing ICP 1. However, caution is required with potential side effects of NSAIDs, and gastric protection may be needed.

Treatment Options

  • Weight loss
  • Short-term painkillers (e.g. NSAIDs, paracetamol)
  • Indomethacin for its effect of reducing ICP It's also important to note that acetazolamide has not been shown to be effective for the treatment of headache alone 1, and lumbar punctures are not typically recommended for treatment of headache in IIH. Regular monitoring of symptoms and intracranial pressure is crucial in managing IIH, and surgical options such as optic nerve sheath fenestration or cerebrospinal fluid shunting procedures may be considered for patients who don't respond to medication.

From the Research

Treatment Options for IIH Symptoms

The primary treatment for symptoms of Idiopathic Intracranial Hypertension (IIH) includes:

  • Medical therapy with acetazolamide, which has been shown to have additional efficacy when compared to weight loss alone 2
  • Structured weight loss, which is often recommended in conjunction with medical therapy 2, 3
  • Surgical treatment, such as optic nerve sheath fenestration or cerebrospinal fluid diversion, which may be necessary for patients with vision-threatening disease 2, 3

Medical Management

Medical management of IIH symptoms may involve:

  • Acetazolamide therapy, which has been shown to be effective in reducing intracranial pressure and improving visual field outcomes 4, 5, 6
  • Topiramate, which may be an alternative treatment option for IIH, although its efficacy has not been as extensively studied as acetazolamide 4
  • Weight loss, which is often recommended as a complementary therapy to medical treatment 2, 3

Surgical Interventions

Surgical interventions for IIH symptoms may include:

  • Optic nerve sheath fenestration, which can help to reduce intracranial pressure and improve visual outcomes 2, 3
  • Cerebrospinal fluid diversion, which can help to reduce intracranial pressure and improve symptoms 2, 3
  • Venous sinus stenting, which may be an emerging treatment option for medically refractory IIH 2
