A review of scientific studies published this week examined the possibility that delirium could be an early symptom of COVID-19, when combined with other early symptoms. Researchers from Oberta de Catalunya University (UOC) investigated the development of delirium in patients with COVID-19 in the days before the manifestation of the most common symptoms: cough and shortness of breath.
It is important to note that research has highlighted a link between loss of smell and taste, headache and delirium in the days before the more common signs of COVID-19 infection.
Researchers Diego Redolar Ripoll and Javier Correa of UOC conducted their research this year when the coronavirus SARS-CoV-2 (leading to COVID-19) holding in the 2020 global pandemic was still active. we. The study, authored by Ripoll and Correa and published this week, explores the research done on the effects of COVID-19 on the central nervous system. Their hypothesis is that COVID-19 has the potential to induce some new cognitive changes.
“The main hypotheses explaining how the SARS-CoV-2 coronavirus affects the brain points to three possible causes: hypoxia or neuronal hypoxia, cytokine storm encephalitis and the fact that the virus is present. the ability to pass through the blood. The brain barrier directly enters the brain, ”said Correa in this week’s commentary on the research. Delirium, headache, and psychosis may be the result of a SARS-CoV-2 / COVID-19 coronavirus infection.
“Delirium is a state of confusion in which a person feels lost from reality, as if they were dreaming,” said UOC researcher Javier Correa. According to Correa, “we need to be vigilant, especially in this epidemiological situation, because an individual with certain signs of confusion could be a sign of infection.”
The study examines “existing evidence on the mechanism of coronavirus infection 2 severe acute respiratory syndrome leading to CNS manifestations in general, delirium in particular.” From what they have gathered, Ripoll and Correa have presented the possibility that “the direct effects of SARS-CoV-2 infection on the human central nervous system and neurological and cognitive complications. Its relevance “may be of guiding importance for both the prevention and treatment of COVID-19.
