Short answer

Post-treatment Lyme disease syndrome, or PTLDS, describes prolonged symptoms such as fatigue, pain or difficulty thinking after recommended Lyme disease treatment. Its cause is not yet known.

At a glance

The symptoms are real and deserve careful assessment, but they do not by themselves prove an ongoing bacterial infection.

Key takeaways

• PTLDS can affect daily life.

• Other possible causes should also be assessed.

• Management should be planned with a qualified clinician.

A name for a recognised pattern

Some people report symptoms that continue after treatment. CDC recommends the term PTLDS because it describes the timing without assuming that live bacteria remain.

Care should remain individual

Fatigue, pain and cognitive difficulty have many possible causes. A clinician can review the original diagnosis, treatment, new symptoms and other health conditions before agreeing a care plan.
