Great questions! Yes, testing for Lyme disease is actually a routine part of the MS diagnostic process. Since some Lyme disease symptoms can closely mimic MS — especially when it affects the nervous system — doctors use blood tests to rule it out before confirming an MS diagnosis. As for how often it gets mistaken, it happens more than you might think. The neurological form of Lyme disease can cause symptoms that look very similar to MS, including:

- Fatigue
- Muscle weakness
- Cognitive difficulties
- Vision changes
- Tingling or numbness

In some cases, Lyme disease can even trigger MS flare-ups, which makes telling the two apart even trickier. The key difference doctors look for is a bull's-eye shaped skin rash, which is unique to Lyme disease. MS does not cause this rash.

To help distinguish between the two, a neurologist may use:

- Blood tests
- MRI scans
- A lumbar puncture (spinal tap)
- A Western blot test to check for Lyme antibodies

Seeing a neurologist who specializes in MS is the best way to get an accurate diagnosis and the right care plan.
