Neuropsychological post-COVID syndrome

# Following severe, moderate or mild infection

About the TRAJECTORY project

The COVID-19 infection, even in its mild or moderate respiratory forms, can lead to neuropsychological deficits. The COVID-COG project (NRP 78 2020-2023, n°: 4078P0_198438) was implemented during the first wave of the COVID pandemic, in response to the questioning at the time concerning the impact that an infection could have on neuropsychological abilities. The original project featured an exhaustive neuropsychological evaluation, as well as MRI, olfactory and neurological assessments, administered 6-9 months and 12-15 months post infection, which allowed our research team to confirm the presence of cognitive dicturbances in the short-term following SARS-CoV-2 infection. These results have since been reinforced by numerous other studies worldwide, revealing that 6 months post-infection, 35.4% of people still display cognitive impairment, and 53% have chronic fatigue, referring to this syndrome as the post-COVID condition. While several hypotheses have been put forward to explain the persistence of these neurocognitive symptoms, many questions remain unanswered, notably the evolution of these impairments in the long-term. As a follow-up to the COVID-COG project, the ongoing TREJECTORY project (SNSF ​​2023-2027, n°: 220041) aims to track the longitudinal evolution of patients 3 and 5 years after the acute phase of COVID-19.

Our projects are realized in collaboration with eight departments of the University Hospitals of Geneva, the Leenaards Memory Centre at the Lausanne University Hospital and the Ecole Polytechnique Fédérale de Lausanne.
