Neurological and psychiatric sequelae of the coronavirus can become evident up to 2 years later. This is confirmed by a study published by the journal ‘The Lancet Psychiatry’. ” Since the early stages of the pandemic, COVID-19 is known to be associated with an increased risk of many neurological and psychiatric sequelae. However, more than 2 years after the diagnosis of the first case, they remain important without response,” the report says.
During the investigation, the experts found that the neurological and psychiatric risks after SARS-CoV-2 follow different trajectories: cognitive deficit, dementia, psychotic disorder and epilepsy or seizures “remains elevated two years after infection”, while the risks of other diagnoses such as mood and anxiety disorders “disappear after two months and do not show a general excess during the two years of follow-up”.
In children, risk trajectories are also different: “They do not have an increased risk of mood disorders or anxiety and their risk of cognitive deficit is transient, but they share the risk of adults of several other diagnoses and have a notable risk of epilepsy or seizures,” the study details.
