In chronic intracranial hypertension, the increased CSF pressure can cause swelling and damage to the optic nerve—a condition called papilledema. Because the symptoms of IIH can resemble those of a brain tumor, it is sometimes known by the older name pseudotumor cerebri, which means “false brain tumor.”

Also to know is, can IIH cause memory loss?

Idiopathic intracranial hypertension (IIH), formerly known as pseudotumor cerebri, is a condition that affects the brain. A person with IIH may also have symptoms such as a stiff neck, back or arm pain, eye pain, and memory problems. If the condition remains untreated, permanent visual loss or blindness may develop.

One may also ask, is intracranial pressure dangerous? Key points about increased intracranial pressure (ICP) ICP is a dangerous condition. It is an emergency and requires immediate medical attention. Increased intracranial pressure from bleeding in the brain, a tumor, stroke, aneurysm, high blood pressure, brain infection, etc. can cause a headache and other symptoms.

Similarly, it is asked, what happens if IIH is left untreated?

Untreated IIH can result in permanent problems such as vision loss. Have regular eye exams and checkups treat any eye problems before they get worse. It's also possible for symptoms to occur again even after treatment.

What happens when intracranial pressure increases?

Increased ICP is when the pressure inside a person's skull increases. When this happens suddenly, it is a medical emergency. The most common cause of high ICP is a blow to the head. The main symptoms are headache, confusion, decreased alertness, and nausea.

Can you get disability for IIH?

If pseudotumor cerebri causes your eyesight to be 20/200 or worse, you will medically qualify for disability benefits. If you don't meet the specific criteria for a condition in the Blue Book, you can still win your disability claim by using the medical-vocational allowance.

Does IIH make you tired?

Fatigue, a requisite in chronic fatigue syndrome, is common in IIH. Headache, usual in IIH, is common in chronic fatigue. Headache may be absent, however, in which case the diagnosis is usually made after papilloedema is discovered by an optician or during fundoscopic examination for visual symptoms.

Does losing weight help IIH?

The relationship between weight and elevated intracranial pressure is not known, though in many cases of IIH, losing weight helps reduce papilledema and sometimes, induces a remission. This is why weight reduction is very important for those who are overweight and have IIH.

Does IIH ever go away?

IIH may go away on its own. You may need any of the following if your symptoms continue or get worse: Medicines may be given to control migraines or decrease the amount of CSF you produce. This will help relieve pressure in your skull.

What does an IIH headache feel like?


That being said a classic IIH headache is severe and throbbing, like a migraine. The pain can be intermittent or constant and may be associated with nausea and/or vomiting. Sometimes, people with an IIH headache will note pain behind their eyes and/or pain with eye movement.

Does IIH cause weight gain?

[44] found that, in 34 newly diagnosed IIH patients and 41 controls, IIH patients reported higher degrees of weight gain in the 12 months prior to the onset of IIH. Higher BMI and percentages of weight gain were also associated with a dose-dependent risk of developing IIH.

Is IIH hereditary?

There is a hereditary component to IIH. In the Idiopathic Intracranial Hypertension Treatment Trial 5% of participants had a family member with IIH. Weight loss is hard to do.

How can I lower my intracranial pressure naturally?

Effective treatments to reduce pressure include draining the fluid through a shunt via a small hole in the skull or through the spinal cord. The medications mannitol and hypertonic saline can also lower pressure. They work by removing fluids from your body.

Does caffeine increase intracranial pressure?

These drugs may have acute or chronic effects on patients with traumatic brain injury. Alcohol intoxication increases cerebral blood flow from 8 to 24%. Caffeine decreases cerebral blood flow from 10 to 20%. Intracranial pressure, respiration, heart rate and the mean arterial pressure was monitored.

Does IIH go away with weight loss?


Weight loss in the range of 6%-10% often leads to IIH remission. Weight loss of ≥5% at 1 year is achieved in roughly 50%-70% of patients if they are enrolled in a high-intensity lifestyle modification program and in 20%-35% of patients if they direct their own weight loss.

Does exercise increase intracranial pressure?

Effects of positioning and exercise on intracranial pressure in a neurosurgical intensive care unit. Limb exercises left the mean ICP essentially unchanged in both the patients with normal ICP and the patients with high ICP. Isometric hip adduction increased mean ICP by 4 mm Hg in patients with normal ICP.

Is it safe to fly with IIH?

Yes - it is safe to fly with or without a shunt if you have controlled and therefore 'normal' ICP levels with your IIH. Some people find that flying causes a temporary worsening of their symptoms especially on take-off and/or landing. Any worsening of symptoms should be short lived once the aircraft has landed.

How common is idiopathic intracranial hypertension?

Idiopathic intracranial hypertension typically occurs in women of childbearing age. Incidence is 1/100,000 in normal-weight women but 20/100,000 in obese women.

Is IIH an autoimmune disease?

Idiopathic intracranial hypertension is a diagnosis of exclusion defined by elevated intracranial pressure without mass lesions or hydrocephalus. Causes of idiopathic intracranial hypertension include obesity, vitamin derangements, antibiotics, corticosteroids, and autoimmune disorders.

Can IIH cause high blood pressure?


Obesity predisposes to systemic hypertension, which therefore, unsurprisingly, is prevalent in the IIH population. Hypertension has been cited in the medical history of between 20%9 and 32%10 of patients with IIH, although blood pressure recordings at presentation were not given.

How long is intracranial hypertension?

For most people, IIH usually improves with treatment. For others, it progressively worsens with time, or it can resolve and then recur. About 5-10 percent of women with IIH experience disabling vision loss. Most patients do not need surgical treatment.

Is idiopathic intracranial hypertension Rare?

Idiopathic Intracranial Hypertension is a neurological condition of unknown cause defined by increased intracranial pressure around the brain without the presence of tumour or disease. It affects just 1:200,000 children and 1-4:100,000 adults.
