A new study of patients who have contracted Covid-19 suggests that neurological symptoms such as psychosis, dementia, mental fog and seizures can persist for more than two years. The conclusion came in Search Conducted by Oxford University and published in the journal Lancet Psychiatry.
“Since the early stages of the epidemic, Covid-19 has been known to be associated with an increased risk of several neuropsychiatric effects. However, more than two years after the first case was diagnosed, three important questions remain unanswered: First, we do not know whether The risks of different post-Covid problems revert to standard values or when they return; secondly, the risk profile in different age groups; and third, whether the risk profiles have changed with the emergence of many variables,” the researchers reported.
So experts analyzed data from 1.25 million patients to see if there really was an answer to these key questions.
The study showed that among adults, 640 out of 10,000 people still had “brain fog” more than two years after recovery. However, the risk was more than double in those over 65 years old – with 1,540 cases per 10,000.
And in the other problems mentioned, the numbers have also doubled among the elderly: 450 out of every 10,000 have dementia; and 85 out of 10,000 reported psychotic breaks.
Researchers report that this type of problem also occurs with other serious respiratory infections, but previous epidemic numbers were much lower.
Neuropsychiatric problems of the so-called “long-Covid” were more rare in children, but not absent: 260 in 10,000 still had seizures – twice the control group – and 18 in 10,000 had psychotic disorders (compared to 6 in all 10 thousand in control).
Among the variables, the Oxford study confirmed that delta variable It is more severe for almost all of the long-term alpha symptoms, the first of which is the spike. However, experts note that there are indications that the Micron variant, which has spread intensively since the end of last year, has the same long-term characteristics as its predecessor – despite the milder symptoms.
