Cognitive dysfunction

Cognitive dysfunction is a constant struggle for most ME/CFS patients and they often describe it as "brain fog".

Cognitive dysfunction in ME/CFS can take many different forms. Cognitive issues commonly observed in ME/CFS include attention deficit, auditory sequencing problems, brain fog, concentration problems, difficulty comprehending social cues, dyscalculia, dyslexia, executive function problems, linguistics reversals, memory loss, multi-tasking problems, planning problems, receptive language problems, slowed thought, spatial disorientation, and word-finding problems.
