| Symptoms Description | Persistent debilitating fatigue lasting at least 6 months that is not alleviated by rest and is not caused by other medical conditions. Accompanied by post-exertional malaise, unrefreshing sleep, cognitive impairment (brain fog), orthostatic intolerance, muscle or joint pain, headaches, sore throat, tender lymph nodes, and sensitivities to light, sound, or chemicals. |
| Diagnosis | Clinical diagnosis based on established criteria such as the Institute of Medicine (IOM) or Fukuda criteria after exclusion of other causes through laboratory tests and medical evaluation. No single diagnostic test exists. |
| Conventional Treatment | Symptom management including cognitive behavioral therapy (CBT), graded exercise therapy (GET) in select cases, sleep management, pain relief with analgesics, antidepressants for co-occurring mood disorders, and pacing techniques. No curative pharmaceutical treatment available. |
| Herbal Treatment | Adaptogenic and tonic herbs such as Panax ginseng (Asian Ginseng), Withania somnifera (Ashwagandha), Rhodiola rosea, Eleutherococcus senticosus (Siberian Ginseng), and Astragalus membranaceus to support energy, immune function, and stress response. Anti-inflammatory herbs including Curcuma longa (Turmeric) and anti-fatigue botanicals such as Schisandra chinensis. Use under practitioner supervision, especially in TCM or Ayurvedic frameworks where it may relate to Qi deficiency, Kidney essence depletion, or Spleen dampness. |
| Prevention | Stress management, adequate sleep, balanced nutrition, regular moderate exercise, and prompt treatment of viral infections or other triggering events. No guaranteed prevention method. |
| Prognosis | Variable; many experience partial improvement over time with supportive care, but full recovery is uncommon. Long-term management is often required. Prognosis improves with early intervention and pacing. |
