The first sign of increased intracranial pressure is a headache. The pain may start suddenly and get worse over time, building up as the pressure on your brain increases.
The buildup of pressure on your skull can come from an excess of cerebrospinal fluid or blood in the brain itself. It can also happen after a head injury or certain types of stroke.

One of the first signs of increased intracranial pressure is a headache. It may start suddenly and be intense or it may build gradually over time. It’s often worse in the upright position. The headache may also be accompanied by vomiting or vision changes (like blurred or doubled vision) and noises inside the head.
If you or your child develops a headache, vomiting and vision changes, it’s an emergency. This means that there is increasing pressure within the skull, probably from excess fluid or swelling of brain tissue. This can further injure the brain or spinal cord and is life-threatening.
This type of headache is called “spontaneous intracranial hypotension.” The cause isn’t known, but it can be caused by a decrease in cerebrospinal fluid production, hyperabsorption or a leak. It’s also thought that a brain tumor or a bleed in the brain could be to blame. If the condition isn’t treated quickly, brain herniation or even death can occur. Medications like acetaminophen and topiramate can help reduce the pressure. In some cases, weight loss and diuretics to reduce fluids are recommended.

If you have experienced a serious head injury, bleeding in or around your brain, or a tumor that is putting pressure on the skull, your doctor will want to monitor your intracranial pressure. This is because high ICP can harm your brain and spinal cord.
Symptoms of elevated ICP include vomiting, drowsiness or confusion and vision changes. If you have a combination of these symptoms, it is a medical emergency. Getting help quickly can prevent long-lasting damage.
ICP is often caused by a head injury, an unruptured brain aneurysm or a brain tumour. It can also be caused by illness such as a brain abscess, meningitis or encephalitis. However, there are times when the cause of the increase in pressure is unknown, this is called idiopathic intracranial hypertension. During a spinal tap or lumbar puncture, doctors can measure the pressure inside your skull directly. This is done by inserting a pressure-sensitive probe through a hole in your skull or by drilling a small tube into a brain ventricle. MRI or CT scans are also used to find the cause of increased intracranial pressure.

The cerebrospinal fluid that naturally cushions your brain and spinal cord can build up in the skull if you have certain health problems, such as blood clots, a tumor or head injury. This can put pressure on your brain and cause symptoms like headache and vomiting.
Sudden increases in intracranial pressure are a medical emergency. The increased pressure can push on crucial brain structures, leading to a stroke or coma. Prompt treatment typically improves the prognosis.
Chronic (long-lasting) intracranial hypertension can result from conditions like blood clots, brain tumors or infections such as encephalitis and meningitis. It can also be due to a herniated brain (a condition where part of the brain tissue bulges out of the space inside the skull).
Some people have a type of intracranial hypertension called idiopathic intracranial hypertension, where CSF builds up for no known reason. This condition is more common in younger women who carry excess weight. It can lead to severe headache, pulsatile tinnitus and vision changes, such as blurring or double vision. Symptoms of this condition can be difficult to distinguish from other health problems, so it’s important to see your doctor right away.

The sudden increase of pressure inside your skull can put too much stress on your brain. This can be a medical emergency. If it’s not treated quickly, the pressure could cause brain injury, seizures, coma, or death. A doctor can tell if you have increased intracranial pressure from your symptoms and medical history. They may also do a spinal tap, MRI, or CT scan to see how much fluid is in your skull. They can also give you medication to reduce swelling or blood clots.
This condition occurs when cerebrospinal fluid, the liquid that cushions your brain and spinal cord, builds up in your skull. This can lead to a decrease in blood flow to your brain or to brain herniation, which is when tissue from your brain moves through the space between your skull and your cranium. Increased intracranial pressure is usually caused by a brain tumor, but it can also be due to other conditions or injuries. It can be sudden or develop slowly over time, like in idiopathic intracranial hypertension (IIH). It used to be called pseudotumor cerebri.

Increased intracranial pressure can cause vision changes in some people. When this happens, you may notice that your eyes look blurry or dim, or they might seem to black out for a few minutes. This can happen when your brain or spinal cord are under pressure, and it is a sign that you need to see a doctor right away.
Most of the time, increased intracranial pressure happens when there is a problem with your cerebrospinal fluid, or CSF, which cushions your spinal cord and brain. This problem could be a result of an injury to your head that causes swelling and fluid buildup inside your skull, or it could occur when you have a stroke that makes blood vessels in your brain burst.
But sometimes, there is no clear reason for the increase in pressure, and your doctors may call this idiopathic intracranial hypertension (IIH). It used to be called pseudotumor cerebri, which means false brain tumor, because the symptoms are similar to those of a brain tumor. If this condition is not treated quickly, it can lead to permanent vision loss.
