Experiencing brain fog after Covid? It could be due to the effect of the virus on the cerebrospinal fluid, according to a new study

brain fog is a condition “in which the thinking ability, calculating ability, or analytical power of the brain becomes sluggish. After the second wave, a few patients complained of forgetfulness, their memory was not going with them. We concluded that this could be due to covid as there were neurological changes in their brains resulting in the slow passage of neurotransmitters,” said Dr. Animesh Arya, Senior Consultant, Respiratory Medicine, Sri Balaji Action Medical Institute. indianexpress.com.

However, according to a recent study by a research team from the University of California, San Francisco (UCSF), this could be due to the effect of the virus on the cerebrospinal fluid. The researchers found high levels of protein in the samples of some Covid survivors after analysis of their cerebrospinal fluid.

This, according to the researchers, indicated that some inflammation occurred as a result of an immune response to the covid19 virus.

Posted in the Annals of Clinical and Translational Neurology, the study recruited 32 Covid survivors for the study. Of these, 22 patients reported cognitive problems after infection.

Dr. Joanna Hellmuth, lead author of the study and researchers from the UCSF Memory and Aging Center, said: “It is possible that the immune system, stimulated by the virus, may be functioning in an involuntary pathological way.”

According to Dr. Arya, “Brain fog can also be caused by meningitis, encephalitis, seizures, strokes, little sweetor low oxygen.

For some people, experience brain fog could be detrimental as they might end up forgetting useful information and having trouble staying focused.

“They manifest as problems remembering recent events, finding names or words, concentrating and problems retaining and handling information, and slow processing speed,” Hellmuth said.

Over time, however, the brain fog gets better and eventually goes away, Dr. Arya added. “Evaluation by a neurologist is necessary to know the true reason for the brain fog so that the correct medication can be administered. On top of that, constant and close monitoring of this situation is necessary to reassure the person that it will eventually get well.
