This is likely what the English link is covering for physical diseases that have a physically harmed nervous system. But if the cause of the issues is due to mental health and stress then you need to address the conditions causing that. You are changing the context from Japanese to English terminology, in which English we don't really equate twitches, dizziness, and fatigue from stress and sleep to that of needing a feeding tube even though its still an effect of the nervous system. We equate a nervous disorder as being that like parkinsons or ALS. All the japanese top results from google refer to mental health, but english refer to physical damage. The picture shows causes of the english term for autonomic dysfunction, and none of it is mental health, but more related to physical disorders.
