Is Arachnoiditis hereditary?

Arachnoiditis is not a hereditary or genetic condition, meaning it is not passed from parents to children through DNA. It is an acquired inflammatory disorder typically resulting from trauma, chemical irritation, or surgery within the spinal canal, rather than an inherited mutation.

Is Arachnoiditis a genetic or hereditary disease?

As a clinical geneticist, I can clarify that Arachnoiditis is neither genetic nor hereditary. While some individuals may have a genetic predisposition to how their immune system responds to inflammation, Arachnoiditis itself is caused by environmental or physical factors. It is considered an acquired condition, meaning it develops after birth due to external triggers, such as spinal surgery, epidural injections, chronic infections, or severe trauma to the spine.

What causes the inflammation in Arachnoiditis?

The inflammation associated with Arachnoiditis occurs in the arachnoid mater, one of the membranes surrounding the nerves of the spinal cord. Because it is not caused by a gene mutation, there is no inheritance pattern, no risk of passing Arachnoiditis to offspring, and no role for prenatal diagnosis. The primary drivers of the disease include:

• Mechanical trauma: Complications arising from multiple spinal surgeries.


• Chemical irritation: Reaction to contrast dyes or medications introduced into the intrathecal space.


• Infection: Bacterial or viral meningitis that creates chronic inflammation.


• Chronic compression: Persistent pressure on the spinal nerves.

Is genetic testing available for Arachnoiditis?

There is currently no genetic testing available or recommended for Arachnoiditis because the condition is not linked to any known genetic markers. Since it is not a hereditary disease, genetic counseling is not typically part of the management plan for patients. If you are experiencing symptoms like burning feet, muscle spasms, or bladder dysfunction, it is vital to see a neurologist or neurosurgeon who can assess your medical history for potential triggers rather than genetic causes. With 423 members on DiseaseMaps.org sharing their experiences, we know that many patients find it helpful to connect with others who have navigated similar diagnostic paths.

Next steps

• Consult a neurologist or neurosurgeon to review your spinal imaging and medical history for potential causes.


• Discuss symptom management strategies, such as anti-inflammatory protocols, with your clinical team.


• Join the Arachnoiditis community on DiseaseMaps.org to share experiences and learn from others living with the condition.
