Symptoms for suspecting ME/CFS
All of these symptoms should be present:
- 1. Debilitating fatigue that is worsened by activity, is not caused by excessive cognitive, physical, emotional or social exertion, and is not significantly relieved by rest.
2. Post-exertional malaise after activity in which the worsening of symptoms:
- is often delayed in onset by hours or days,
- is disproportionate to the activity,
- - has a prolonged recovery time that may last hours, days, weeks or longer.
3. Unrefreshing sleep or sleep disturbance (or both) , which may include:
- - feeling exhausted, feeling flu-like and stiff on waking,
- - broken or shallow sleep, altered sleep pattern or hypersomnia.
4. Cognitive difficulties (sometimes described as 'brain fog') , which may include:
- - problems finding words or numbers,
- - difficulty in speaking,
- - slowed responsiveness,
- - short-term memory problems, and difficulty concentrating or multitasking.
