What is central nervous system vasculitis?

CNS vasculitis is a very rare disease which leads to the inflammation of the small arteries and veins in the brain and/or spinal cord. The brain and spinal cord together constitute the CNS.

The disease affects less than three people per million, regardless of gender or age, and is related to an overactive immune system that attacks the blood vessels in the brain. This inflamed vessel wall can cut off the oxygen-containing blood supply to the brain, leading to a loss of brain function or stroke. CNS vasculitis can be a manifestation of an underlying autoimmune disease, such as Sjogren's syndrome or lupus, or it can occur in isolation.

Because CNS vasculitis is a condition that rarely occurs, there is much still to be known about the reasons why it happens.

What are the signs and symptoms of vasculitis of the central nervous system?

A variety of different symptoms can develop with CNS vasculitis, including:

• Headache of a sudden onset and intense nature, prolonged for days, weeks, months, or more.
• Acute ischemic attacks, or strokes often referred to as "mini-strokes."
• Confusion or forgetfulness.
• Weakness.
• Vision changes.
• Seizures.
• Expansion of the brain, or encephalopathy, may present with changes in the level of mood or personality combined with decreased awareness.
• Sensory disturbances.

What causes vasculitis of the central nervous system?

It is not altogether clear how inflammation might arise in the brain's blood vessels. In other vasculitis disorders, abnormal antibodies-a-k- also known as auto antibodies-vv function against white blood cells, fuelling inflammation and damage to the vessel walls. CNS vasculitis can also result from a viral infection.

How is central nervous system vasculitis diagnosed?

It's challenging to diagnose CNSV. It involves ruling out other diseases, infections, and disorders that share the same symptoms. Since one test cannot be determined to diagnose CNSV, your doctor would base the evaluation on many factors, for instance, these includes:

• Lab work: Laboratory tests in primary CNSV are usually normal, but for secondary CNSV, they may not be.
• Analysis of the spinal fluid: The fluid surrounding the spinal cord and the brain is taken as a sample for signs of irritation and infection. A needle inserted in the lower back will extract this fluid. We call this a spinal tap.
• Diagnostic imaging: Anomalies within the brain, spinal cord, and other organs and tissues are detected with magnetic resonance imaging and computed tomography scans. Additional imaging that takes a view of the brain's blood arteries, and commonly comprised of the diagnostic workup is magnetic resonance angiography (MRA) and computed tomography angiography (CTA) scans.
• Cerebral angiogram: A contrast agent, which is another name for an angiography dye, is injected into the blood arteries during a cerebral angiogram. X-rays are then taken that can identify blockages and narrowing in the cerebral blood arteries.
• Biopsy: A biopsy is a surgical procedure in which a small amount of brain tissue is taken. Microscopically, it is examined for evidence of tissue damage or inflammation. A brain biopsy can be indicated in an effort to make a more definitive diagnosis because other diseases can cause CNS-like brain abnormalities.

How is vasculitis of the central nervous system treated?

Generally, CNS vasculitis is treated in stages.

The first stage is called induction therapy. In this context, steroids are usually prescribed at high dosages, usually intravenously, either in conjunction with or separately from other immunosuppressive drugs such as mycophenolate mofetil or cyclophosphamide that reduce the response of the immune system to autoimmune diseases. At six months, steroids are tapered off.

In the maintenance phase, which comes after remission, cyclophosphamide (if administered in the induction phase) is substituted with another immunosuppressive drug, for example, mycophenelate mofetil. Low-dose steroids may be administered during the maintenance phase. Treatment must be continued for a long time, probably forever.

Treatment should also encompass recommendations for the patient's specific condition if they have systemic vasculitis or another illness (such as lupus).

What are the side effects of central nervous system vasculitis?

The drugs used in the treatment of CNSV have severe side effects. These include:

• Lowering the body's capability to fight infections
• Potential bone loss (osteoporosis), among others.

Therefore, your regular check-ups by the doctors will be an essential thing for you. Medication is also required for these kinds of side effects.

Prevention of infection is another important aspect. Discuss flu vaccine, pneumonia vaccination, and shingles vaccination with your doctor in order to have a reduced chance of infection.

What to do if suffering from central nervous system vasculitis?

Sometimes, living with a chronic disease like CNSV can be overwhelming. Fatigue, pain, emotional stress, and medication side effects can undermine your sense of well-being.

This can impact your relationships, work life, or other domains of your daily life. Contacting family and friends to explain your experience, finding others in a support group who share your condition, or consulting a mental health professional can make all the difference.

What is the outlook for central nervous system vasculitis?

At present, there is no known cure for CNSV. But it is curable. It requires early diagnosis and treatment so that loss of brain function or stroke does not occur.

Follow-up medical care is important even with the treatment of CNSV because relapse rates are high with CNSV.
