![]() The majority of the individuals who experienced post-COVID cognitive symptoms (59%) and the control group participants (70%) met the predefined criteria for cognitive impairment. Notably, the average number of preexisting cognitive risk factors was higher in the individuals with post-COVID cognitive symptoms than in those in the control group.Ī neuropsychologist also evaluated various aspects of the participants’ cognitive function using multiple tests. The high proportion of the participants with a delayed onset of cognitive symptoms may allow for the use of early mental health interventions to prevent these symptoms. The participants experiencing a delayed onset of cognitive symptoms were likely to be younger than those who developed the symptoms during the acute phase. The researchers found that more than 2 in 5 individuals who experienced post-COVID cognitive symptoms had an onset of symptoms at least 1 month after contracting SARS-CoV-2. The time between the SARS-CoV-2 infection and the interview was about 9 months for the individuals with cognitive symptoms, and 15 months for those in the control group. ![]() ![]() The questionnaire also helped determine the presence of risk factors, such as a history of anxiety, depression, high blood pressure, or diabetes, before the infection that would predispose the participants to cognitive dysfunction. The remaining 10 participants were in the control group. A cognitive neurologist interviewed them using a standardized questionnaire to determine whether they had developed cognitive deficits after contracting SARS-CoV-2.īased on the interviews, the researchers determined that 22 participants had experienced cognitive symptoms after the acute phase of the SARS-CoV-2 infection. The present study involved 32 participants who had experienced mild COVID-19 symptoms during the acute phase of the infection. This small study was a part of the Long-term Impact of Infection with Novel Coronavirus (LIINC) study, which is a collaboration among researchers at UCSF to understand the long-term effects of a SARS-CoV-2 infection. The researchers conducted the present study to better understand the mechanisms behind and risk factors for post-COVID cognitive symptoms. Health experts describe these persistent COVID-19 symptoms as long COVID or post-acute COVID syndrome.Ĭognitive symptoms - such as difficulty maintaining attention, as well as deficits in memory and executive function - are some of the most common symptoms individuals experience beyond the acute phase of the infection. A substantial minority of individuals with SARS-CoV-2 infection continue to experience symptoms beyond the initial 3–4 weeks after contracting the virus. ![]()
