Covid, brain disease risk 2-4 times higher

(ANSA) – ROME, JUN 24 – (EMBARGO AT 00.01 ON JUN 25) Double to quadruple risk of developing neurodegenerative diseases (such as Alzheimer’s and Parkinson’s) after Covid among patients not hospitalized for the infection. Diseases also include ischemic and hemorrhagic stroke.

This is what emerged from a new study presented today at the eighth congress of the European Academy of Neurology (EAN) and conducted by Pardis Zarifkar, of the Neurology Department of Rigshospitalet in Copenhagen, Denmark.

The study, which analyzed the medical records of more than half of the Danish population, found that those who tested positive for COVID-19 had an increased risk of Alzheimer’s, Parkinson’s and ischemic stroke. Out of 919,731 people who took the COVID-19 test as part of the study, the researchers found that the 43,375 people who tested positive had a 3.5 times greater risk of being diagnosed with Alzheimer’s disease, 2.6 times greater risk of being diagnosed with Alzheimer’s disease. Parkinson’s disease, 2.7 times of ischemic stroke and 4.8 times greater of intracerebral haemorrhage (hemorrhage in the brain).

“More than two years after the start of the pandemic – notes Zarifkar – the precise nature and evolution of the effects of COVID-19 on neurological disorders have remained unclear. Previous studies have established an association with several neurological syndromes, but so far it is not known whether COVID-19 also affects the incidence of specific neurological diseases and whether its effects differ from other respiratory infections. “

Compared to a diagnosis of influenza or other respiratory diseases, however, Covid patients do not appear to be much more in danger of neurological sequelae, although it was found that they had almost double (1.7 times greater) risk of ischemic stroke than patients with influenza and bacterial pneumonia over the age of 80.
