Hi, @marycoy, welcome to Mayo Clinic Connect. That's great you are trying to help your granddaughter get the right treatment for her conversion disorder/ functional neurological disorder.

Your search to better understand this disease and what is the source of her symptoms - malfunction between the nervous system and the brain, or something psychological and behavioral - sounds wise. Here is some Mayo Clinic information that may be useful in your search for further clarification on the source of your granddaughter's symptoms.

I'd like to ask @uldiver @amber3212 @jubilee @techi @jenniferhunter to offer their thoughts on the source of the symptoms for patients who have a Conversion Disorder/ Functional Neurological Disorder diagnosis like your granddaughter.

Has your granddaughter seen multiple doctors to consult about her condition, @marycoy? Has any treatment been recommended to this point?
