Can NMOSD in the spinal cord cause paralysis if untreated?

Question

Hello doctor,

My sister is a 48-year-old female with NMOSD and recently had symptoms suggestive of a possible spinal relapse. We got medical help quickly, but honestly, reading about spinal cord attacks has scared our entire family.

Some articles say weakness or even paralysis if treatment is delayed. Now we are trying to get a sense of how bad these attacks can get.

NMOSD attacks involving the spinal cord can cause paralysis from the waist down if left untreated. Fast treatment is usually what makes the difference in how much recovery someone gets.

Kindly suggest.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

I am so sorry your family is going through this fear, because neuromyelitis optica spectrum disorder (NMOSD) can sound very alarming when you read about worst-case scenarios.

In NMOSD, the inflammation can involve a long segment of the spinal cord and interrupt nerve signals that control strength, sensation, and bladder or bowel function. So yes, spinal cord attacks can be serious.

A serious relapse of the spine, if left untreated for too long, can cause severe weakness or even paralysis of the legs and in some cases, long-term disability. The key point, however, that is very important and often reassuring, is that early treatment makes a big difference.

Quick treatment with high-dose steroids and other agents, including plasma exchange when necessary, can greatly reduce inflammation and the extent of permanent damage.

Many patients who get prompt treatment recover at least some function and sometimes significant improvement over time, though recovery depends on the severity and how fast treatment was started.

Because time matters for protecting the spinal cord, doctors treat NMOSD relapses as urgent neurological emergencies.

So even though the condition can be serious, your family did the most important thing, which was to get treatment quickly, and that early response is one of the strongest factors in improving outcomes.

I hope this will help you.
