One of the most debilitating aspects of the novice coronavirus is how much it affects the body's organs.
It affects the heart, lungs and respiratory system, but now the mystery is growing about how it affects the nervous system.
A study of 214 code 19 patients in April this year indicated that they had suffered from a variety of brain complications, ranging from loss of sense of smell to stroke.
The virus can cause brain complications such as cerebral palsy, stroke and nerve damage, and a study by University College London this month found that 10 out of 43 patients had temporarily inactivated brain function, while 12 had cerebral palsy. 8 suffered stroke and 8 suffered nerve damage.
Last month, a study of 153 patients in the medical journal The Lancet Psychiatry found that people under the age of 60 were at risk for depression, anxiety or stroke.
How the virus damages the brain and nerves is not yet completely clear, but two experts decided to do research on the nervous system to find out some answers.
These experts were amazed that the brain protects itself in an amazing way, but still the corona virus interferes with the central nervous system.
The most common mental symptom of COD 19 is loss of sense of smell and taste, which is the first indication that a person has contracted the corona virus.
Other possible symptoms include headache, dizziness, loss of consciousness, weakness, paralysis, paralysis and others.
It is now known that the virus is spread by particles in the air, so the first way to enter the human body is through the nose and mouth.
When this happens, it may pass through the bone above the nose and reach the sensory area.
If the virus damages these nerves, the infected person may lose the sense of smell and taste.
Well, that's a theory at the moment, but one study found that 88% of the 417 people diagnosed with code 19 with these symptoms recovered in 2 weeks and didn't have any more mental problems.
One theory is that the virus targets a protein receptor S2 found in the lungs, kidneys, blood vessels, muscles, nose and mouth, and prevents nerve cells from sending sniffing and tasting signals.
S2 also plays a role in stabilizing blood pressure and protecting the heart and brain from damage, for which it lowers the levels of a molecule called angiotensin II. When this happens, the blood supply to the limbs is limited, which puts them at risk for damage.
An interesting fact that is now beginning to come to the knowledge of experts is that most of the symptoms are not a direct result of the virus but rather a strong immune response that fights against it.
Dr. Majid, director of the Neuro Grow Brain Fitness Center at Johns Hopkins Medicine, said the story of a virus about which we have no genetic information, the way it wreaks havoc on the body, is shocking.
For example, when the virus targets S2 in the blood vessels, an immune response is triggered, causing a massive swelling that affects the functions of the body's clotting system and causes innumerable clots. Is.
In addition, high levels of angiotensin II in the blood vessels can lead to blood clots or clots that affect the blood supply to the brain and increase the risk of stroke.
Dr. Majid said that some patients who beat Code 19 may show symptoms of silent paralysis such as depression, anxiety, insomnia or mental retardation in the near future.
But sometimes the severity of the stroke is very severe or even fatal, especially in people over the age of 30 and 40, which is not commonly seen.
Excessive inflammation causes the protective wall that protects the brain to break down, leading to brain swelling or disease.
Some patients with the virus have been diagnosed with Gavlian Bad Syndrome, a neurological disorder that can lead to paralysis.
When antibodies are formed in response to a virus, they react against proteins in the nerves, causing damage.
But it is important to keep in mind that everyone's reaction to the virus is different.
According to Dr. Majid, there are people whose immune response to the virus is easily controlled, healthy people who do not show symptoms of the virus, their immune system apparently without blood clots or harmful immune response to the virus. Eliminates
Mental complications are not limited to Code 19, they have been seen in people suffering from flu, measles and Zika viruses, while they have been recorded in patients with measles and mumps.
This happens when 2 basic mechanisms are affected, namely, a direct viral attack on the nervous system and a highly activated immune system.
Some mental complications such as confusion or weakness are also insignificant symptoms of a serious illness and are not related to the virus.
