Scientists are now warning of a potential wave of brain damage that appears to be linked to COVID-19.
The New York Post reported the new study, which lays out evidence suggesting COVID-19 can lead to severe neurological complications, including delirium, psychosis, and inflammation.
According to researchers at University College London, the study described 43 cases of patients with coronavirus who suffered either temporary brain dysfunction, nerve damage, or strokes. Other people experienced other severe brain effects.
According to CNN, one of the patients in the study hallucinated seeing "lions and monkeys in her house."
“Given that the disease has only been around for a matter of months, we might not yet know what long-term damage COVID-19 can cause,” Ross Paterson, who co-led the study, said.
Paterson added that doctors need to be aware of possible neurological effects, so they can find them early and improve “patient outcomes.”
Nine of the patients who participated in the study who had brain inflammation were also diagnosed with a rare condition called acute disseminated encephalomyelitis. The disease is known as ADEM, which is usually seen in children and can be triggered by viral infections.
Researchers reported that they usually see one patient per month diagnosed with ADEM at the London clinic. However, due to the coronavirus pandemic, officials see the numbers spike at least once per week.
The research adds to other studies which also found COVID-19 can damage the brain.
The experts said more studies will be "essential" to fully understand the potential long-term neurological effects of the novel virus.
