Hi @marycoy. I also have FND and I have been told and have come to believe as a result of my treatment that it stems from a central sensitization issue and psychological issues are NOT the root cause. Mayo Clinic successfully treats patients with FND as a central sensitization syndrome within their 3 week pain rehabilitation program. The same protocols used to address chronic pain also work for other FND symptoms. It has changed my life and for that reason I highly recommend the program. If you have not already viewed Dr. Sletten's video that explains central sensitization, you can view it at https://www.youtube.com/watch?v=8defN4iIbho. Dr. Sletten is located at Mayo Clinic in Florida, but the same program is available at Mayo Clinic in Rochester and Arizona. If your granddaughter has not already had a consult at one of Mayo Clinic's Pain Rehabilitation Centers, it may be valuable for her to request a consult with one of the Pain Rehabilitation Center teams. She can self-refer to request an appointment if her local physicians are not familiar with this program, or not willing to make the referral for her.
