A hospital in East China's Jiangsu Province has set up a "brain fog" clinic, becoming the latest hospital across China to set up such clinics to treat sequela of COVID-19 infection.

"Brain fog" usually comes with decreasing memory, lack of undivided attention, slow in mind and reaction. And it may even include forgetting words or disordered logic when talking, according to Yuan Yonggui from Zhongda Hospital affiliated with Southeast University. 

The hospital began integrating the "brain fog" clinic into its operation starting from Tuesday.

The Global Times found many hospitals including Xiangya Hospital affiliated with Central South University based in Changsha, Central China's Hunan Province had set up similar clinics as early as January. 

"Brain fog" is not a scientific term, usually used to describe chronic fatigue syndrome and some autoimmune diseases. A dozen of diseases would result in "brain fog" such as depression and attention deficit hyperactivity disorder (ADHD).
