Study reveals cognitive impairments in postcovid syndrome

An ongoing Spanish study of cognitive impairment in people who passed the COVID-19[feminine] reveals the appearance of cognitive deficitsparticularly in attention and processing speed, executive function and episodic memory, according to several articles published in scientific journals.

One of the works of researchers from the Neuroscience Institute of the Clínico San Carlos Hospital in Madrid, published in the Journal of Clinical Medicine, studies the relationship between fatigue and the Cognitive function in the post covid syndromeaccording to a communicated from the health center.

Fatigue is one of the “most frequent and debilitating symptoms of this syndrome, having a physical and cognitive component. In this study, patients were assessed using one of the most widely used fatigue scales in science (MFIS) and an extensive neuropsychological assessment protocol,” he adds.

Using machine learning algorithms, an attempt was made to predict the results of the fatigue assessment with the data obtained from the neuropsychological assessment, although the models were not in able to reliably estimate the presence or absence of fatigue, including cognitive, or its severity.

“These results are important to know the characteristics of the cognitive deficits observed in the post-covid syndrome. Our research results support that fatigue, depression, anxiety and cognitive deficits likely have different mechanisms in post-Covid syndrome, which is important for the approach and development of treatments for this disease,” explains researcher Jordi Matias-Guiu Antem.

In another study published in Brain Sciences, personality traits were assessed in people post covid syndrome.

The researchers concluded that certain personality characteristics were associated with the development of anxiety there the Depressionas it happens with other chronic pathologies, but “not with cognitive deficits, fatigue or sleep quality”.

In a third study, published in the Journal of Psychiatric Research, scientists examined patients who reported persistent symptoms for months after suffering from COVID-19 using a cognitive assessment comprehensive, of which 74 percent were women with an average age of 51 years.

They assessed the fatiguethe depressive symptomsthe anxietythe dream and the olfactory function concluding that “no relationship was observed between depressive symptoms or anxiety with cognitive function”.

The bone cognitive deficits observed confirm that “SARS-CoV-2 infection is associated with objective cognitive impairments” through cognitive examination.

Although the cognitive impairments “were generally mild or moderate in magnitude”, the fact that they affect young people suggests “high impact”, according to the research.

“Knowing the pattern of cognitive alterations in the post-covid syndrome is important, on the one hand, for the differential diagnosis with other pathologies; on the other hand, it is a first step to seek interventions that allow these deficits to be improved,” emphasizes Matías-Guiu.

The study consists of a comprehensive assessment of patients that lasts three days, with a battery of several-hour tests provided by neuropsychology experts and other computerized ones self-administered by the participants themselves.

In addition, the results obtained with magnetic resonance imaging and blood biomarkers are correlated.
