Post-exertional malaise (PEM)/post-exertional symptom exacerbation
(PESE) is an altered physiological state and pathognomonic finding
unique to ME/CFS that is now being recognized in those with post-acute
sequelae of COVID-19 (PASC), also known as Long COVID.
It is critical that healthcare professionals recognize PEM/PESE and
support the patient in avoiding a push-crash-cycle which can
exacerbate disease processes and contribute to worsened long-term
functional prognoses.
In video six of this seven-part series Brayden Yellman, MD, and
Lucinda Bateman, MD, examine the physiological happenings within the
brains of those with ME/CFS.
Video details:
- Microglial cells & proinflammatory cytokines (IL-6, TNF-alpha, and
interleukin-1-beta)
- Magnetic resonance spectroscopy & metabolic activity associated with
neuroinflammation - Brain lactate & Choline
- Brain thermometry
- Positron emission tomography (PET): measuring radio-labeled isotope
ligand to the translocator protein (or TSPO)
- Default Mode Network (DMN) uncoupling in ME/CFS
