Experts: There is no research to clarify the causality between new crown and "brain fog"
"After recovering from the new coronavirus infection, I felt that my reaction was a bit slow."
On January 1, Ms. Sun from Chaoyang District, Beijing, told reporters: "You have to deliberately control your concentration when working. Yesterday at noon, I ordered two takeaways, and I felt stupid."
Wang Gongqiang, chief physician of the Department of Neurology of the Affiliated Hospital of the Institute of Neurology of Anhui University of Traditional Chinese Medicine, told reporters that in fact, "brain fog" is not a medical term or a scientific term, but a description of a type of feeling that is not a symptom. After recovering from COVID-19, most of the "brain fog" symptoms will gradually ease.
Wang Gongqiang told reporters: "Long before the emergence of the new coronavirus, 'brain fog' has been used to describe the decreased attention and executive dysfunction that occur in conditions such as chronic fatigue syndrome. mainly includes one or more manifestations such as slow thinking and reaction, vagueness, confusion, mental fatigue, inability to concentrate, or the inability to concentrate on one thing.
"Currently, there is no research that can clarify the causality between COVID-19 and 'brain fog'. However, we can speculate that the physical and mental fatigue and weakness caused by infection with COVID-19 will also cause us to experience 'brain fog' symptoms to a certain extent." Wang Gongqiang said.
How to relieve the symptoms of "brain fog" after the new crown epidemic?
Wang Gongqiang gave a few tips -
- You can reasonably consume some dietary supplements, such as GPC (glyphosatecholine).
- Good sleep, a proper diet, and scientific exercise can improve memory and other symptoms of brain fog.
- It is necessary and very important to get vaccinated before infection, gain muscle and lose fat, take antiviral treatment promptly after infection, drink enough water, increase the intake of protein , and get adequate sleep and rest.
"Even if your study and work efficiency becomes lower after recovering from the new coronavirus, don't worry too much about 'becoming stupid'. As long as you make good adjustments, most of the 'brain fog' will gradually ease within 1 month to 1 year." Wang Gongqiang said.
