A new study presented at the VII Congress of the European Academy of Neurology (EAN) has found that patients with COVID-19 suffer from cognitive and behavioral problems two months after receiving hospital discharge.
Problems with memory, spatial awareness and Information processing problems were identified as possible virus outbreaks in post-COVID-19 patients who were followed up for eight weeks.
The research also found that 1 in 5 patients reported post-traumatic stress disorder (PTSD), with a 16% presentation. depressive symptoms.
The study, conducted in Italy, consisted of testing neurocognitive skills and performing MRI scans of patients two months after experiencing COVID-19 symptoms. More than 50% of patients experienced cognitive impairments; 16 %% had problems with executive function (governing working memory, flexible thinking and information processing), 6% experienced visuospatial problems (difficulty judging depth and seeing contrast), 6% had impaired memory and 25% manifested a combination of all these symptoms.
Across the sample, the increased severity of acute respiratory symptoms of COVID-19 during hospital admission was associated with poor performance of executive function.
In addition, a longitudinal observation of the same cohort at 10 months of COVID-19 showed a reduction in cognitive impairment from 53 to 36%, but a persistent presence of PTSD and depressive symptoms.
The lead author of the study, Professor Massimo Filippi, of the Scientific Institute and Vita-Salute University San Raffaele, Milan, Italy, explained: “Our study has confirmed that significant cognitive and behavioral problems are ‘associate with COVID-19 and persist several months after disease remission.’
“A particularly alarming finding is the changes in executive function that we have found, which can make it difficult for people to concentrate, plan, think flexibly and remember. These symptoms affected three out of four younger patients who were older. labor “.
No significant relationship was observed between cognitive performance and brain volume within the study.
“Larger studies and long-term follow-up are needed, but this study suggests that COVID-19 is associated with significant cognitive and psychopathological problems,” concluded Dr. Canu, researcher at the San Raffaele Hospital in Milan and first author of the study. “Proper follow-up and treatments are critical to ensure that these previously hospitalized patients receive adequate support to help alleviate these symptoms.”
