During the initial findings of covid-19 long-term symptoms, it has been witnessed that people are having problems with smell and taste loss. Further studies on the cause and effects have suggested that the SARS-CoV-2 virus appeared to be affecting nerves that carry information from the nose to the brain, which is marked as a sign of worry by neurologists. It is evident that SARS CoV-2 is going to invade the brain.
In fact, this damage may come from the body and brain’s response to the virus rather than the virus itself. Many patients who are hospitalized for COVID-19 are discharged with symptoms such as those associated with a brain injury. These include “forgetfulness that impairs their ability to function. Such patients usually complain about trouble with focusing on their work like organizing their tasks.
Alzheimer’s is a type of dementia that affects memory, thinking, and behavior. Symptoms eventually grow severe enough to interfere with daily tasks COVID-19 also appears to produce similar brain-related symptoms ranging from seizures to psychosis. COVID-19 may even increase a person’s risk of developing Alzheimer’s disease. Scientists are still trying to understand the many ways in which COVID-19 can damage the brain. It’s been clear since early in the pandemic that the infection can lead to blood clots that may cause a stroke. Some patients also suffer brain damage when their lungs can no longer provide enough oxygen. For understanding, these damages to the brain scientists required brain tissue from patients with COVID-19 who died. And early in the pandemic, they couldn’t get that tissue as there due to the covid-19 infectious nature, in fact, they lack the availability of the protective gear that would allow them to remove a brain safely.
However, that scenario has now been changed with the availability of the required safety gadgets or what we call corona innovations. According to the latest findings of The New England Journal of Medicine, it is reported that there is widespread evidence of inflammation and damage. It was found that the very small blood vessels in the brain were leaking. Such injuries from a series of tiny strokes occurring in many different areas of the brain.
These findings from the brain cells have provided traces of such a wide range of brain-related symptoms, including some related to brain areas that control functions such as heart rate, breathing, and blood pressure. Complaints of heart racing, dizzy feeling while standing, urinary problems & feeling extreme fatigue, are all caused by a brain injury and have been recorded in the covid-19 recovered people. The inflammation and leaky blood vessels associated with all these symptoms may make a person’s brain more vulnerable to another type of damage
Findings from that research should help answer some important questions about what happens to COVID-19 patients after an infection. Researchers will assess patients’ behavior, their memory, their overall function” at six-month intervals to conclude the overall impact of the long term covid-19 symptoms.
