  • Human Herpesvirus 6 (HHV-6) and Its Role in Disease

    HHV-6 AHHV-6 BDiagnosisTreatmentResearch links HHV-6 A to numerous neurological conditions. Some of these links are supported by considerable evidence, while other ties are less certain. At this point, we can't say for certain that HHV-6 directly causes any of these conditions. Diseases linked to HHV-6 reactivation are many. For most of them, though, we don't know if HHV-6 is the actual cause. These diseases include:2 1. Autoimmune diseases, such as Hashimotothyroiditis, Sjogrensyndrome, lupus, multiple sclerosis, and Guillain-Barre syndrome 2. Bone marrow suppression 3. Cancer, including Hodgkin lymphoma, gliomas, and cervical cancer 4. Chronic fatigue syndrome 5. Cognitive dysfunction, including delirium and amnesia 6. Colitis 7.
