A high degree of mental comorbidity has risen questions of classification, if HA is a primary mental disorder and therefore its own disease entity, or the symptoms are only secondary to another mental disorder like a melancholic depression, or if HA is better classified as a personality disorder [37] or an anxiety disorder [38]. In DSM-V and ICD-11 the disorder entity is suggested preserved and kept categorized under somatoform disorders, but the name is suggested changed to illness anxiety disorder in DSM-V and health anxiety in ICD-11.
