The study, conducted by the American Mount Sinai Hospital, and its results were published in the “Gamma” journal, was based on data from 740 patients with Covid-19, during the period from April 2020 to May 2021.
The researchers compared rates of cognitive impairment among those treated in an outpatient setting, an emergency department, or in an inpatient setting.
The study examined a wide range of cognitive impairments including attention, processing speed, executive function, vocal fluency, and a number of memory functions.
The study said: “We found a relatively high frequency of cognitive impairment several months after patients contracted COVID-19. Impairments in executive functioning, processing speed, speech fluency, and memory coding were prevalent among hospitalized patients.”
“Approximately 25 percent of patients who are not admitted to the hospital still have some cognitive impairment,” she added.
The study indicated that 8% of patients in outpatient clinics, and 10% of those who were treated in the emergency department, suffered from memory problems, while the percentage for the group residing in the hospital was 15%, while the percentage for outpatients was 15%. As reported by UPI news agency.
The average age of the participants in the study was 49 years, which made scientists warn of the negative impact of the Corona virus on the younger age group, compared to previous research that confirmed the link between Covid-19 and cognitive decline in the elderly.
The study indicated that “it is known that certain population groups (such as the elderly) may be particularly susceptible to cognitive impairment after infection with corona. However, in the relatively small group in this study, a large proportion showed cognitive impairment after several months of recovery from Covid-19. “.
