CNS Vasculitis Definitions & Explanations
CNS (Central Nervous System) Vasculitis can be overwhelming for patients, caregivers, families, and all of those affected. To help guide you through these tough times, the Brian J Patterson Foundation has compiled clear definitions and explanations of key medical terms related to CNS vasculitis.
This guide is designed to provide clarity, support informed conversations with medical providers, and help you better understand what to expect throughout the journey.
What is CNS Vasculitis?
CNS vasculitis is a rare inflammatory disease that affects the blood vessels in the brain and spinal cord. When these blood vessels become inflamed, they can narrow or weaken, reducing blood flow and potentially causing neurological damage (Cleveland Clinic; Vasculitis Foundation).
Because the brain and spinal cord control essential body functions, inflammation in this area can lead to serious symptoms and complications.
What Is an Autoimmune Disease?
An autoimmune disease occurs when the immune system mistakenly attacks the body’s own healthy tissues instead of protecting it from infection. In CNS vasculitis, the immune system targets blood vessels within the central nervous system (Cleveland Clinic).
What Is a Stroke?
A stroke occurs when blood flow to part of the brain is interrupted or reduced, depriving brain tissue of oxygen. CNS vasculitis can increase the risk of stroke due to inflamed or narrowed blood vessels (Mayo Clinic).
Stroke symptoms require immediate medical attention.
Primary vs. Secondary CNS Vasculitis
Primary CNS vasculitis occurs without another underlying condition causing it.
Secondary CNS vasculitis develops as a result of another condition, most commonly autoimmune disorders or infections (Cleveland Clinic).
What Is a Lumbar Puncture?
A lumbar puncture, sometimes called a spinal tap, is a procedure used to collect cerebrospinal fluid for testing. It may help doctors identify signs of inflammation or infection affecting the central nervous system (Cleveland Clinic)
