Strokes and Mental Changes – Subtle hints on how COVID-19 affects the human brain

Recently in the UK, 125 people have been admitted and diagnosed with COVID-19 and carry the symptoms of strokes, confusion and psychosis.

These results were described in  Lancet Psychiatry on June 25 and they come from a group of severely sick people, thus the data of how common these types of neurological symptoms may be in a more general population of COVID-19 affected patients is still inconclusive.

“Brain-related symptoms of COVID-19 patients can slip through the cracks. These relatively rare but incredibly severe complications get missed, like needles in a haystack,”

-Benedict Michael; neurologist at the University of Liverpool in England.


By conducting a survey with these patients with the help of stroke physicians, psychiatrists and other doctors across the United Kingdom, they have found that under the enlistment of 125 patients, 77 patients have experienced and interruption of blood flow to the brain and it is most often caused by a blood clot, making them to be a well known pernicious COVID-19 complication along with strokes being seen in younger people who have been affected by this virus. About a third of the 125 patients had a shift in mental state, including confusion, personality change or depression. Eighteen of 37 patients with altered mental states were younger than 60. So far, it’s unclear exactly how SARS-CoV-2 causes these symptoms.

Now that we know the rough idea of the scale of this, we desperately need research that gets to the disease mechanisms,”
