According to RT news (Russia), researchers at the Cleveland Clinic, Ohio State, USA, have revealed that cognitive disorders, including dementia, are increasingly being reported as a common complication. in patients infected with the SARS-CoV-2 virus that causes COVID-19 disease.

“The report states that neurological complications in COVID-19 patients and in patients with persistent COVID-19 who persist after recovering from illness are becoming more common. This suggests that the SARS-CoV-2 virus may have long-term effects on brain function," the study's authors said.

The aim of the researchers was to explore the mechanism underlying brain-related complications, such as delirium and loss of taste or smell, commonly seen in COVID-19 patients. To conduct the study, they compared at the molecular level the host genes of COVID-19 and those responsible for several neurological disorders.

After collecting data from both COVID-19 patients and those with Alzheimer's disease, the scientists used artificial intelligence to analyze each contact between them. They also analyzed genetic factors that could allow the virus to infect brain tissues and cells and identified an "important link" between COVID-19 and Alzheimer's. They concluded that Alzheimer's patients may not be able to protect themselves against this dangerous virus because they have fewer protective antiviral genes.

“While researchers have found little evidence that the virus targets the brain directly, they have found a strong link between the virus and the genes/proteins involved in a number of neurological diseases. , most notably Alzheimer's disease. At the same time, they show how COVID-19 may lead to Alzheimer's dementia," the study published in this week's journal Alzheimer's Disease Research and Treatment wrote.

After demonstrating a coincidence between COVID-19 disease and common brain changes in Alzheimer's patients, scientists will conduct research into how the SARS-CoV-2 virus causes cognitive disorders and learn how to prevent this.

“Identifying the link between COVID-19 and neurological problems will be important for the development of effective prevention and treatment measures that address the increasing neurocognitive decline. that we might see in the near future,” said the study's lead author, Feixiong Cheng.

Previous studies have also shown complications affecting the brains of COVID-19 patients and those infected with other viruses. Accordingly, one-fifth of patients recovering from severe acute respiratory syndrome (SARS-CoV-1) or Middle East respiratory syndrome (MERS) experienced memory impairment, while those recovering from severe acute respiratory syndrome (SARS-CoV-1) or Middle East respiratory syndrome (MERS) experienced memory impairment. People with COVID-19 also experience symptoms such as disorientation, inattention, and confusion.

In addition, a study of 230,000 patients found that those with COVID-19 who survived being hospitalized in the intensive care unit were at an even greater risk of neurological and psychiatric disorders.
