According to a recent study using specialized MRI machines, some COVID patients’ brains were altered by the disease. Researchers from the Indian Institute of Technology (IIT) Delhi have discovered brain abnormalities in patients up to six months after they recovered from COVID-19 using a specialized sort of MRI.
According to studies, COVID-19 causes roughly one in five persons to experience long-term consequences later. Some of the neurological symptoms of long COVID include Cognitive and attentional difficulties, headaches, sleep issues, lightheadedness, pins and needles sensations, changes in taste or smell, and depressive or anxious symptoms.
Additionally, there were variations in the regions of the brain involved in language generation and comprehension, attention, motor inhibition and imagery, social cognitive processes, hormone-release signaling, sensory and motor signaling, and sleep-wake cycle control.
Microbleeds, vascular malformations, brain tumors, and stroke can all be detected and monitored using magnetic susceptibility, demonstrating how some materials, like blood, iron, or calcium, become magnetized in a magnetic field.
According to study co-author Sapna Mishra, a Ph.D. candidate at the Indian Institute of Technology in Delhi, previous research has not explicitly examined how this magnetic susceptibility might change after a coronavirus infection.
MRI Research Results :
The imaging was performed within six months of recovery. Among the COVID patients, fatigue, difficulty sleeping, lack of attention, and memory issues were the most frequently reported symptoms; these are potential symptoms of long COVID. The researchers analyzed the MRI results of 46 recovered from COVID and 30 healthy control patients.
The findings demonstrated that the frontal lobe and brainstem of the COVID patients had “significantly higher susceptibility values.” This study suggests that the coronavirus may produce severe long-term consequences even months after infection recovery.
To determine whether these anomalies will last for a more extended period, the researchers are carrying out a longer-term investigation.
According to the study, the most often reported symptoms among patients with lengthy COVID were fatigue, trouble sleeping, inattentiveness, and memory issues.
According to Mishra, variations in the susceptibility levels of different brain areas may signify local compositional alterations.
Frontal lobe and brain stem susceptibility values in COVID-19 survivors were found to be significantly higher than those of healthy controls, according to MRI results.
Millions of people in Europe are currently thought to have long-term COVID, and some studies have begun showing potential long-term impacts.
Long COVID can cause various neurological symptoms, such as trouble thinking or concentrating, headaches, sleep issues, lightheadedness, pins-and-needles sensations, changes in taste or smell, and depressive or anxious feelings.
According to earlier research, COVID-19 can cause the brain to contract, lowering the amount of gray matter in the areas that govern emotion and memory. A study from Oxford University also revealed that it might harm the regions responsible for the smell.
The authors claimed that the effects may be observed in people who had not been hospitalized and that longer-term research was required to determine whether the impact could be mitigated. The study, which examined 785 volunteers between the ages of 51 and 81 and was peer-reviewed, was published in the journal Nature in March.
Several investigations have established the possible adverse effects of COVID-19 infection on cognitive functioning.
These symptoms or issues were previously not researched well but as of now when again the research was done, there are many symptoms that are seen in people who have suffered from COVID.
Among various studies, one had also discovered that a severe infection could harm cognitive function by the same amount as 20 years of aging of people.
