There is ongoing research about the short- and long-term damage COVID-19 may possibly cause to the brain. [36] including in cases of 'long COVID'. For instance, a study showed how COVID-19 may cause microvascular brain pathology and endothelial cell-death, disrupting the blood–brain barrier.
Long COVID is a patient-created term coined early in the pandemic by those suffering from long-term symptoms. [ 12 ] [ 13 ] While long COVID is the most prevalent name, the terms long-haul COVID , post-COVID-19 syndrome , post-COVID-19 condition , [ 1 ] [ 14 ] post-acute sequelae of COVID-19 ( PASC ), and chronic COVID syndrome are also in use.
While it is commonly assumed that people either recover or die from infections, long-term symptoms—or sequelae—are a possible outcome as well. [1] Examples include long COVID (post-acute sequelae of SARS-CoV-2 infection, PASC), Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and post-Ebola virus syndrome. [1]
Around 10% to 30% of non-hospitalised people with COVID-19 go on to develop long COVID. For those that do need hospitalisation, the incidence of long-term effects is over 50%. [76] Long COVID is an often severe multisystem disease with a large set of symptoms. There are likely various, possibly coinciding, causes. [76]
Data from the University of Alabama at Birmingham notes that mRNA vaccines, like the COVID shot, deliver their payload and then quickly leave your body, so this eliminates the concern of any long ...
[1] [15] Hence, the WHO recommends that clinicians explicitly ask long COVID patients whether symptoms worsen with activity. [1] The 2-day Cardiopulmonary Exercise Test (CPET) may aid in documenting PEM, showing apparent abnormalities in the body's response to exercise. [17] Still, more research on developing a diagnostic test is needed.
A COVID-19 vaccine is intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), the virus that causes coronavirus disease 2019 . Prior to the COVID-19 pandemic, an established body of knowledge existed about the structure and function of coronaviruses causing diseases like severe acute ...
Traumatic brain injury (TBI, physical trauma to the brain) can cause a variety of complications, health effects that are not TBI themselves but that result from it. The risk of complications increases with the severity of the trauma; [1] however even mild traumatic brain injury can result in disabilities that interfere with social interactions, employment, and everyday living.
