The coronavirus does-it of neurological disorders ?

Some patients with Covid-19 are neurological disorders. A study published in April in the journal of the Association of american medicine (Jama) reported on 214 chinese patients, 36% had neurologic symptoms, ranging from loss of smell to nerve pain, and even seizures and strokes. If these phenomena are sometimes due to the lack of oxygen in the blood, some health professionals have very quickly been referred to by other hypotheses, such as an immune response is abnormal, a "storm of cytokine" — which would cause an inflammation in the brain called encephalitis, autoimmune disease, or viral encephalitis.

But a recent study, led by Akiko Iwasaki, immunologist at Yale university, and published in September it was confirmed that the neurological disorders might be related to the ability of the coronavirus to enter the brain. "Evidence of the ability neuroinvasive of SARS-CoV2, and an unexpected consequence of direct infection of neurons by the SARS-CoV-2", have been demonstrated. "During the autopsy of the brain of patients who died as a result of the Covid-19, we detect the SARS-CoV-2 in cortical neurons, and note the pathological features associated with infection with a minimum of immune cell infiltrates", explain the researchers. The virus disease Covid-19 is therefore well able to invade the brain and duplicate.

in addition, american doctors have noticed an increase in cerebral vascular accidents (STROKE) in patients with Covid young and middle-aged. In the Washington Post, Pascal Jabbour, a neurosurgeon at the hospital, Thomas Jefferson, said that many cases had unusual features. Usually the blood clots to appear in the arteries that carry blood away from the heart. However, in patients of Covid-19, the clots can also form in the veins and are more difficult to treat. Sherry H-Y Chou, a neurologist at the university hospital of Pittsburgh, has been hypothesized that these conditions would be consistent with "friendly fire", that is to say, to an immune response disproportionate. If you notice any symptoms of a STROKE (such as dizziness ; numbness and collapse of a part of the face, an arm, a leg or a part of the body ; problems élocutions...), please contact the 15 most quickly.

The Covid can it cause hair loss ?

The coronavirus could cause a loss of hair on some people who were positive for Covid-19. According to a study published in August by the researcher and a professor Natalie Lambert from the University of medicine of Indiana, this symptom has appeared several times. On 1 567 respondents, 423 attest to these falls, which is approximately 27% of the subjects. One of the participants in the study explained that she had lost 75% of its mass capillary after having contracted the disease. This would of effluvium telogen, disordered capillary at the origin of significant hair loss or localized, usually caused by stress. According to Dr. Esther Freeman, a researcher at the American Academy of Dermatology, hair loss begins to see themselves in the three months following the stress.

ocular symptoms

The symptoms of Covid-19 are similar to those of other infectious diseases typical of the winter season : cough, fever, body aches... Some people may also experience breathing difficulties. Over the year, various signs of the SARS-CoV-2 have been discovered by doctors and scientists. The search continues always in the end of the year, and allow to set in the light of other symptoms. A study published in November 2020 in the medical journal BMJ Open has found that irritated eyes are a sign of the coronavirus.

An online questionnaire was made available to people affected by the Covid-19. An audit of the signs of the participants, their frequency and duration, has been made. The ocular symptoms of the sick is being manifested before their infection were compared with those while they were being affected by the coronavirus. On the 83 participants of the study, 66% have suffered from dry cough, 76% of the fever, 90% of the fatigue and 70% of the ageusia and anosmia. In regard to the ocular signs, the three most common symptoms among the participants of this research were photophobia, which is sensitivity to light (18%), sore eyes (16%) and itchy eyes (17%). The authors of this study explained that "the frequency of irritated eyes was significantly higher during the Covid-19 (16%), compared to the pre-Covid (5%)". No difference between men and women were identified. The scientists added that "81% of the participants reported being victims of ocular symptoms in the two weeks after the other symptoms of the coronavirus". 80% also stated that they lasted less than two weeks.
