Normal Pressure Hydrocephalus vs Pseudotumor Cerebri

1. Definition of Normal Pressure Hydrocephalus

Normal Pressure Hydrocephalus (NPH) is a serious neurological condition caused by a buildup of cerebrospinal fluid (CSF) within the ventricles and subarachnoid spaces of the brain. This increase in intracranial pressure, or pressure within the skull, can lead to a wide range of symptoms such as dementia, walking difficulty and urinary incontinence. NPH is typically diagnosed in older adults and can be considered a reversible form of dementia if treated in a timely manner. Diagnosis involves a CT or MRI of the brain and spinal fluid analysis to measure CSF pressure. Treatment focuses on the removal of excess CSF from the brain, typically through a lumbar puncture (LP), followed by the insertion of a shunt to help regulate pressure. With proper treatment, most patients can improve significantly or resolve their symptoms.

2. Definition of Pseudotumor Cerebri

Pseudotumor cerebri (also known as ‘benign intracranial hypertension’) is a neurological condition where there is increased pressure in the skull due to an excess of cerebral spinal fluid (CSF). It is an uncommon disorder, that predominantly affects women, and those in their early middle age. It is thought to be caused by an obstruction of the flow of CSF or a lack of absorption of CSF. Symptoms of pseudotumor cerebri usually include headache, balance problems, visual issues, tinnitus, and pulsatile tinnitus. Treatment is usually focused on reducing the amount of CSF, with most patients being given steroids, diuretic medications, or surgical shunts to alleviate symptoms.

3. Symptoms of Normal Pressure Hydrocephalus

Normal Pressure Hydrocephalus (NPH) is a neurological disorder that is characterized by a buildup of cerebrospinal fluid in the brain. This causes a number of symptoms, including difficulty walking, memory loss, and dementia. However, the most common symptom of NPH is a lack of coordination of the gait, often causing the person to have a wide gait and difficulty turning. This is caused by the increased pressure on the brain, which affects the body’s ability to control movement. Other symptoms of NPH include difficulty with urination, incontinence, and confusion. In extreme cases, some people may experience seizures due to the increased pressure on the brain. Diagnosing this condition can be difficult, as these symptoms can also be caused by other neurological disorders. It is important to get a diagnosis from a qualified medical professional if you think you may be suffering from NPH. With proper treatment and therapies, many people with this condition can lead a normal life.

4. Symptoms of Pseudotumor Cerebri

Pseudotumor Cerebri or Idiopathic Intracranial Hypertension is a medical condition which is caused by an increase in the pressure of cerebrospinal fluid surrounding the person’s brain and spinal cord. This condition has many symptoms which can made it difficult for people to make a correct diagnosis. These symptoms can be mild to severe and include persistent headaches, persistent pain in the neck and shoulders, vision problems, ringing in the ears, nausea, vomiting, and dizziness. Visual disturbances are common with this condition and can include double vision, temporary blindness, and blurred vision. In some cases, vision in one eye can be impaired while the other eye remains unaffected. Other symptoms which may be experienced include severe fatigue, difficulty concentrating, and difficulty with memory. This can lead to difficulty with everyday tasks and activities. In extreme cases, these symptoms can lead to paralysis and even coma.

5. Causes of Normal Pressure Hydrocephalus

Normal Pressure Hydrocephalus (NPH) is a neurological disorder caused by an accumulation of cerebrospinal fluid in the brain. It is most often caused by a buildup of pressure within the skull which results in enlargement of the ventricles of the brain. This can lead to a number of symptoms, including difficulty walking, loss of bladder control, difficulty thinking or remembering, and mental confusion. While the exact cause of NPH is unknown, there are a number of medical conditions that can make a person more susceptible to developing it. These include certain types of brain tumors, head trauma, meningitis, and stroke. In addition, the condition can develop in older adults as a result of age-related changes in the structure or function of the brain. It is most commonly seen in men over the age of 60. Treatment for NPH usually involves medications to reduce the pressure in the brain, as well as physical and occupational therapy to help manage some of the symptoms. Surgery is sometimes used when more conservative treatments fail to help.

6. Causes of Pseudotumor Cerebri

Pseudotumor Cerebri, or false brain tumor, is an uncommon condition that can cause many of the same symptoms as a real brain tumor. It is caused by increased pressure in the skull, similar to that of Hydrocephalus. However, pseudotumor cerebri is not caused by a blockage, but rather an imbalance of fluids in the brain. It is most often caused by a defect in the absorption of cerebrospinal fluid, leading to an accumulation of fluid in the brain, as well as a decrease in the amount circulating to and from the brain. Risk factors include obesity, migraines, and certain drugs, such as diuretics or tetracycline. Although it is not a life-threatening condition, it can lead to permanent damage if not treated promptly. Signs and symptoms of pseudotumor cerebri include headache, nausea, vomiting, pulsing sensations in the eyes, blurred vision, double vision, and hearing loss. Treatment involves medications to reduce pressure and reduce fluid production, and in some cases, surgery.

7. Diagnosis of Normal Pressure Hydrocephalus

Normal Pressure Hydrocephalus (NPH) is a progressive neurological condition caused by an accumulation of cerebrospinal fluid (CSF) in the brain’s ventricles. Diagnosis of NPH is not always straightforward and may require several steps to accurately identify the condition. To confirm a diagnosis of NPH patients may be tested with a combination of physical exam, medical history review, imaging tests, and a lumbar puncture to measure the pressure of their CSF.

  1. Physical Exam
  2. Medical History Review
  3. Imaging Tests
  4. Lumbar Puncture

A physical Exam may include a physical examination, review of the patient’s vital signs, neurological examination, and balance and gait tests. During the medical history review, the patient will provide information on the onset and progression of their symptoms and any other chronic health conditions. An imaging test such as an MRI or CT scan can provide information about the size and shape of the patient’s ventricles, as well as any other abnormalities. Lastly, a lumbar puncture involves removing a sample of CSF from the lower part of the spine and analyzing it for pressure and other factors to aid in diagnosing NPH. With the proper diagnosis and treatment, many patients with NPH can improve their quality of life.

8. Diagnosis of Pseudotumor Cerebri

Pseudotumor cerebri is a neurological condition that is characterized by an accumulation of spinal fluid in the brain, resulting in increased intracranial pressure. It is a rare disorder, primarily affecting adults and is estimated to affect up to 5 in 100,000 people. The exact cause of pseudotumor cerebri is unknown, however, it is believed to be related to a disruption in the cerebrospinal fluid (CSF) circulation either due to birth defects, head trauma, or other medical conditions. Diagnosis of pseudotumor cerebri is made based on clinical symptoms, confirmed with neuroimaging such as an MRI or CT scan. The main symptoms of the condition include:

  1. Headache
  2. Vision problems such as blurred vision, double vision, or blind spots
  3. Hearing difficulties
  4. Balance problems
  5. Nausea
  6. Tinnitus

Other tests may be performed to diagnose the condition such as a lumbar puncture to measure the pressure of the CSF and a visual field test to measure the extent of the vision problems. A definitive diagnosis of pseudotumor cerebri requires that all other possible causes of increased intracranial pressure be excluded. Treatment may involve medications to reduce the pressure or surgery to relieve the pressure buildup.

9. Treatment of Normal Pressure Hydrocephalus

Normal Pressure Hydrocephalus (NPH) can be treated effectively with a surgical procedure called a shunting procedure. In this procedure, a surgeon places a small tube into the brain’s ventricles to help drain the extra cerebrospinal fluid (CSF), reducing the pressure on the brain. This tube is then connected to a reservoir placed near the patient’s abdomen, allowing the CSF to be absorbed and re-circulated in the body. The shunt is externally adjustable, allowing doctors to adjust the amount of CSF that is drained as needed. In some cases, physical therapy or medications may be used to help improve mobility and cognition. After the procedure, patients often experience a rapid improvement in their symptoms and quality of life.

10. Treatment of Pseudotumor Cerebri

Pseudotumor Cerebri is a neurological disorder which can lead to increased pressure in the skull, causing headache, vision problems and even blindness due to optic nerve damage. The treatment of this disorder is an ongoing process and requires a multidisciplinary approach. Medical interventions include medications such as diuretics, corticosteroids, acetazolamide and more recently, carbonic anhydrase inhibitors. Surgery is also sometimes necessary to reduce intracranial pressure and remove a mass or cyst. In addition to medical treatments, lifestyle modifications such as weight loss, regular exercise, proper nutrition, stress management, and avoiding certain medications can also be beneficial in treating pseudotumor cerebri. These treatment plans should be designed and monitored by a team of healthcare professionals to ensure the best possible outcomes for the patient.
