COVID-19 could put us at a greater risk of neurodegenerative diseases and stroke

COVID-19 could be joined to an amplified chance of neurodegenerative diseases these types of as Alzheimer’s disease and Parkinson’s condition, a review carried out at Rigshospitalet, Copenhagen, has located.

The scientists statistically analysed information taken from equally in- and outpatients in Denmark soon just after the coronavirus pandemic struck concerning February 2020 and November 2021.

Of the 919,731 individuals that tested for COVID-19, they discovered that the 43,375 who tested good had a 3.5 situations greater possibility of getting identified with Alzheimer’s condition, 2.6 times with Parkinson’s condition, 2.7 occasions with stroke and a 4.8 occasions amplified danger of with struggling from bleeding in the mind.

The improve in risk of neurological illnesses was similar to individuals who experienced contracted influenza or other respiratory health problems, but COVID individuals in excess of the age of 80 had been noticed to have a 1.7 periods improved threat of stroke in comparison to influenza and pneumonia patients.

“More than two years just after the onset of the COVID-19 pandemic, the exact nature and evolution of the results of COVID-19 on neurological conditions remained uncharacterised,” claimed guide writer Dr Pardis Zarifkar, from the Office of Neurology, Rigshospitalet.

“Previous scientific studies have established an affiliation with neurological syndromes, but until now it is unidentified no matter if COVID-19 also influences the incidence of specific neurological conditions and irrespective of whether it differs from other respiratory infections.”

The influence may be because of to swelling in the mind brought on by the virus but a lot more get the job done is essential on the results of long COVID, the researchers say.

On the other hand, there was no enhance in the risk of other neurodegenerative diseases such as a number of sclerosis, myasthenia gravis, Guillain-Barré syndrome.

“We observed guidance for an improved threat of getting identified with neurodegenerative and cerebrovascular problems in COVID-19 good in contrast to COVID-19 damaging sufferers, which have to be verified or refuted by significant registry research in the close to long term,” reported Zarifkar.

“Reassuringly, aside for ischemic stroke, most neurological conditions do not appear to be much more regular just after COVID-19 than immediately after influenza or local community-obtained bacterial pneumonia.

“These conclusions will help to notify our understanding of the lengthy-term outcome of COVID-19 on the physique and the part that bacterial infections perform in neurodegenerative conditions and stroke.”

The research was offered at the 8th European Academy of Neurology (EAN) Congress in Vienna.
