What causes Parsonage Turner syndrome ?
What causes Parsonage Turner syndrome? The exact cause of Parsonage Turner syndrome (PTS) is unknown. Researchers suspect that most cases are due to an autoimmune response following exposure to an illness or environmental factor. In many cases, no triggering event or underlying cause can be identified. Factors known to trigger PTS include: Infections (both viral and bacterial) Surgery Vaccinations Childbirth Certain medical procedures, such as a spinal tap or imaging studies that require administration of radiologic dye Strenuous exercise Certain medical conditions, including connective tissue disorders and autoimmune disorders Injury Some researchers believe that PTS is a multifactorial condition, which means that it is caused by both environmental and genetic factors. In this case, a person may have a genetic susceptibility to PTS due to one or more genes, but won't develop the condition unless they are exposed to certain environmental triggers (such as those listed above).
