COVID-19 infection can do a lot of damage to our health. Not only it impairs the immune system but also hampers other organs and their functions, brain being one of them. Getting infected with this virus can put you at risk of neurodegenerative diseases. Particularly older adults are at a greater risk of suffering from irreversible neurological complications.
According to a study published in the journal ‘Ageing Research Reviews’, COVID-19 infection can accelerate brain aging putting older adults at risk of developing neurodegenerative diseases. Besides, this infection also makes a person prone to stroke and bleeding in brain, which may get fatal.
The research team from the Houston Methodist Research Institute, US found that coronavirus can have long-term impact on human brain. It can invade your brain as well as other vital organs especially if they fall under the vulnerable category. Researchers examined various brain aging studies and came to a conclusion that covid-19 infection may trigger the formation of microbleed lesions that lead to brain bleeding. This can hamper a person’s memory and cognition. These microbleed lesion are also identified in people with diabetes, depression, chronic stress and other comorbidities.
Researchers found that COVID-19 can induce micro-haemorrhagic lesions that affect brain cells and damage DNA. This can hamper brain microstructure-vasculature which can result in the onset of neurological diseases like Parkinson’s and Alzheimer’s. This can cause a lot of damage to a person’s brain making it age faster than usual. In simpler terms, covid can cause brain-related diseases in the long run.
Brain fog was reported to be one of the potential after-effect of coronavirus infection which is also a psychological condition. This involves symptoms like forgetfulness, memory loss, concentration issues, poor focus, numbness, etc. Not just that, elders are also susceptible to cardiovascular diseases and respiratory issues related to brain bleeding and microbleed lesions. These are prevalent in people who got infected with covid and got hospitalised.
Research associate this with cellular aging which is found to be faster in COVID-19 patients. The infection makes the brain go into hibernation mode. In extreme cases, virus-infected cellular cells may even die. This shows the severe impact of covid on overall health.
