Playing Does COVID-19 Hide in Your Brain?

Can COVID-19 hide and linger in the brain and cause a relapse of symptoms?

The Doctors discuss a study that found the virus can lay dormant in the brain and in some cases may cause forgetfulness, depression, brain fog, mania, and even speech issues. 

Before you begin to worry too much, neuroimmunologist Dr. Sharon Stoll notes the study in question was conducted on mice, and so far, she says in humans there has not been much evidence showing the virus hides in our brains. She says COVID patients can develop neurological issues, with the most concerning being strokes, blot clots, and heart attacks.

"There is no evidence to suggest that COVID-19 hides in the brain or attacks the brain," she says, explaining there is not any strong data showing that the virus attacks the brain. It is believed a possible reason some COVID patients develop neurological issues may be related to the body's immune response and not because the virus targets the brain. Dr. Stoll notes this complication is, thus far, very rare.

She also notes that up to 30 percent of COVID patients can have lasting neurological issues, like aches, malaise, brain fog, and chronic headaches -- and these symptoms persist for up to months after other symptoms subside and do not usually occur as a relapse.

The Doctors note because COVID is such a new disease, there is still much that is unknown and the long-term effects of the virus are still being studied.
