A review of scientific research published this week tested the possibility that delirium may be an early symptom of COVID-19 and be combined with other early symptoms,media reported. Researchers from the Open University of Catalonia (UOC) looked at the development of delirium in patients with COVID-19 in the days before the most common symptoms, such as coughing and breathing difficulties.
Notably, the study highlighted the link between more common symptoms such as loss of smell and taste, headache and delirium in the days before COVID-19 infection.
Researchers Deego Redolar Ripoll and Javier Correa of the UOC Cognitive Neurology Laboratory discussed the effects of COVID-19 on the central nervous system in a research paper published this week. Their hypothesis is that COVID-19 has the potential to produce several types of neurocognitive changes.
“The main hypothesis of the new coronavirus explains three possible causes of SARS-CoV-2 affecting the brain: hypoxia or lack of oxygen in neurons, inflammation of brain tissue caused by cytokine storms, and the fact that the virus can invade the brain directly through the blood-brain barrier,” Correa said in a commentary on the study this week. The new coronavirus SARS-CoV-2 / COVID-19 infection process can lead to delirium, headache and psychotic episodes.
“Delirium is a state of confusion in which people feel out of touch with reality, like they’re dreaming,” said Javier Correa, a researcher at the University of Utah and one of several researchers on the study. “We need to be vigilant, especially in such epidemiological situations, because a person who shows some signs of confusion may be a sign of infection, ” he said. “
Based on the information collected, Ripoll and Correa raise the possibility of a direct impact of SARS-CoV-2 infection on the human central nervous system and its associated cognitive and neuropsychiast complications, which may be instructive for the prevention and treatment of COVID-19.
