Скачать или смотреть Neurologic Mechanisms: Critical Long COVID Sx Part 2 04

Long COVID, a chronic aftermath of COVID-19, affects 1–2.5% of survivors globally, translating to tens of millions. It involves persistent or new symptoms well beyond the acute infection phase. Core features include cognitive impairment (brain fog, headaches), profound fatigue and weakness, and chronic inflammation. The underlying pathology involves neuroinflammatory processes, mitochondrial dysfunction, and systemic immune dysregulation. Diagnosis integrates patient history, neurocognitive testing, MRI, and biomarkers like IL-6 and CRP. Treatment uses targeted, multimodal therapies, including cognitive rehabilitation, energy conservation, and immunomodulators. While patients often gradually improve, Long COVID imposes substantial societal and economic burdens.

Key Concepts
Long COVID: persistent, varied symptoms post-acute COVID-19 infection.
Key manifestations: brain fog, headaches, fatigue, chronic inflammation.
Neuroinflammation results in cognitive deficits, headaches, and altered pain perception.
Mitochondrial dysfunction causes fatigue, weakness, and impaired energy metabolism.
Chronic inflammation involves sustained immune activation, leading to tissue injury.
