Study finds an EEG signature for people with #LongCovid, made up of slower beta wave rebound after handgrip testing and slower alpha waves at rest. Slower beta rebound tracked with worse cognition, and slower alpha frequency tracked with worse fatigue. https://t.co/cFb1YYOuUK 7.7K views · 268 likes · 97 reposts · 5 replies Open on X →

New @patientled-funded study on haptoglobin after PEM in #LongCovid! Everyone is born with 1 of 3 types: Hp1-1, Hp2-1, Hp2-2. The team found that Hp2 groups, esp Hp2-2, were less likely to recover from PEM & had less brain oxygen extraction than Hp1. https://t.co/3dFnavEceK 1/ 8.1K views · 221 likes · 57 reposts · 4 replies Open on X →
