Ganglionopathy?: This could be due to autoimmune ganglionopathy which is inflammation of the autonomic ganglia. This may occur following a viral infection or in association with an underlying connective tissue disease such as lupus which may or may not fully manifest itself. You need autonomic testing and anti-neuronal antibodies for evaluation. The condition is treatable with steroids and immunosuppression.
