Long COVID, also termed post-acute sequelae of SARS-CoV-2 (PASC), affects 5–30% of COVID-19 survivors. Symptoms persist ≥12 weeks post-infection, encompassing fatigue, cognitive dysfunction ('brain fog'), breathing difficulties, and autonomic disturbances. Aetiology remains multifactorial, including persistent viral fragments, immune dysregulation, and microvascular endothelial injury.
Diagnosis is clinical, based on symptom history post-confirmed COVID-19 without alternative explanation. Investigation excludes cardiac (echocardiogram, Holter monitoring), pulmonary (spirometry, CT), and other systemic causes. Rehabilitation approaches are individually tailored; exercise intolerance and post-exertional malaise (PEM) require cautious, graded activity progression, often guided by pacing strategies and activity monitoring. Cognitive rehabilitation addresses brain fog and memory impairment. Rehabilitation programmes emphasise a patient-led, personalised approach, avoiding over-exertion which worsens PEM. Symptomatic management includes antihistamines (mast cell activation), beta-blockers or fludrocortisone (autonomic dysfunction), and antidepressants or anticonvulsants (pain and mood). Anticoagulation is explored in patients with suspected microclotting. Pulmonary rehabilitation supports breathlessness.
Dietary interventions targeting anti-inflammatory foods, omega-3 supplementation, and antioxidant-rich nutrients reflect physiological support for immune dysregulation; evidence is anecdotal. Herbal remedies including long-acting herbal adaptogens (ashwagandha, rhodiola) and immune-supporting herbs (medicinal mushrooms: reishi, cordyceps) are used in some traditional medicine systems, though clinical validation in Long COVID is absent. Hyperbaric oxygen therapy is explored in some centres despite limited robust evidence. Acupuncture and traditional Chinese medicine are practised with variable anecdotal support.
Stem cell therapy is studied for Long COVID, targeting immune dysregulation and endothelial dysfunction. Bone marrow-derived stem cells and mesenchymal stem cells possess immunomodulatory properties and may promote vascular repair and regeneration. Early-stage pilot trials investigate infusion therapy in patients with severe persistent symptoms; mechanisms are proposed but clinical efficacy is not yet established. Outcomes are highly variable and treatment protocols remain non-standardised. Candidate assessment focuses on severe, disabling Long COVID unresponsive to comprehensive rehabilitation.

Post-exertional malaise is worsening of symptoms after physical or mental exertion, sometimes with a lag of hours to days. Management prioritises pacing: activity titration to individualised thresholds, with activity tracking to avoid overexertion. Gradual, supervised increases in activity tolerance are preferred over aggressive exercise prescription.
Some patients experience deterioration with standard exercise protocols due to post-exertional malaise. Patient-led, pacing-based approaches and low-intensity activity such as gentle walking or stretching are preferred. Individualised assessment by Long COVID specialists guides appropriate rehabilitation.
No. While anxiety and depression are common comorbidities, Long COVID is recognised as a multi-system condition involving neurological, immunological, and vascular dysfunction. Psychiatric symptoms are addressed as part of holistic care, not as primary pathology.
