Cognitive Issues
Another common symptom of chronic fatigue syndrome is the problem with thinking and memory capability, especially brain fog. Scientists believe that there might be slowing processing of information that results in this sign. Symptoms of brain fog may range from mild to serious and can last for days. Specific issues include concentration issues, short-term memory, word recall, and use issues, difficulty multitasking, or spatial disorientation. Keep in mind that brain fog is not a required sign for a diagnosis of chronic fatigue syndrome. Either orthostatic or brain fog should be present for a doctor to make a diagnosis. [3]
