Scientists have created tiny brains and infected them with the coronavirus.What They Saw Could Explain Long COVID
in new research was announced in molecular psychiatry, Swedish researchers and Harvard University Hospital in Boston have attempted to create “brain organoids,” miniature brains about the size of pinheads, and infect them with COVID.
What they saw explained many things: An “excessive number” of synapses, or connections between brain cells that allow them to communicate, had been removed in the course of the disease.author wrote October 27 Articles on academic news sites conversation.
In a process known as “pruning,” the normal brain removes a certain amount of inactive synapses that are no longer needed to make way for new synapses. However, infected mini-brains displayed unnecessary and excessive levels of cleansing processes similar to those seen in neurological disorders such as schizophrenia, Alzheimer’s disease and Parkinson’s disease.
What researchers witnessed may explain many reasons why long-term COVID patient We report neurological symptoms and report why COVID appears to increase the risk of developing several neurological disorders.
this is It has been established People infected with COVID are at increased risk of complications such as stroke, memory loss, depression, anxiety and migraines. More than a third of his COVID-infected people report neurological symptoms, according to. February article of Treatment advances in chronic diseases.
And some long-term COVID patients have neurological symptoms such as tremors, movement problems, involuntary muscle contractions, seizures, hearing and vision problems, balance and coordination problems, and other Parkinson’s-like symptoms. The most frequent neurological symptoms of long COVID include “brain fog,” headaches, confusion, sleep disturbances, mood disturbances, problems with smell or taste, and autonomic imbalanceDisorders of the autonomic nervous system with fainting, decreased blood pressure on standing, increased heart rate, and other involuntary bodily function problems.

The study, in addition to imaging studies of people who survived it, reports neuronal death and reduced gray matter thickness in the brain, a sign of synaptic loss. Say.
close to 20% of American adults infected with COVID—estimated 50 million— Data collected by the U.S. Census Bureau this summer reported that COVID symptoms lingered even after the infection cleared.
Long-term COVID is loosely defined as symptoms that persist or emerge for an extended period of time after the initial COVID infection is gone, but no consensus definition is yet widely accepted.
Many experts believe that long-lasting COVID, like chronic fatigue syndrome, that develops after COVID illness, as well as other post-viral syndromes that can occur after contracting herpes, Lyme disease, or even Ebola. I argue that it is best defined as a state. Other complications after COVID Things like post-intensive care syndrome shouldn’t be defined as long COVID, they say.
