American scientists have revealed that people who suffer from long-term symptoms of the Corona virus may be more susceptible to developing Alzheimer’s disease and other neurodegenerative diseases in the future. It is known as long-term Corona virus, or post-Covid syndrome, as the continuation of symptoms of infection with the virus for months or years after the initial infection, and includes fatigue, mental confusion, shortness of breath, andMemory problems.
Long-term coronavirus increases the risk of Alzheimer’s disease
A recent study from Stony Brook University in New York showed that levels of the tau protein, which is closely linked to Alzheimer’s disease, rise significantly in the blood of long-term coronavirus patients.
The researchers explained that the entanglement of tau protein clumps inside brain cells leads to disruption of nerve signals, memory loss, and cognitive deterioration, which raises the possibility of chronic brain diseases.
Dr. Benjamin Love, an infectious disease expert and lead author of the study, said: The long-term impact of Covid-19 may be severe for years after infection, and may lead to neurological and cognitive problems similar to what we see in Alzheimer’s disease, stressing that these results have important implications for the development of vaccines and treatments to prevent acute infections before they turn into long-term symptoms.
The researchers analyzed blood samples from 454 people, half of whom reported cognitive problems after infection with Covid-19, and the other half were used as a control group. The results showed that 59% of those with long-term Covid had elevated levels of tau protein compared to before infection, while no increase was observed in the control group, indicating that long-term Covid may worsen neurological symptoms over time.
Data from the National Health Service in England indicate that about one in ten people believe they suffer from long Covid, while about 982,000 people in the United Kingdom suffer from Alzheimer’s disease, and this number is expected to rise to 1.4 million by 2040.
The researchers warned that the study results may be affected by the environmental factors of the participating group, but they confirm the urgent need to monitor brain health in long-term Covid patients and take preventive measures to reduce the risk of dementia and Alzheimer’s in the future.
