The Coronavirus 2019 (COVID-19) pandemic has resulted in at least four million infectionsin Norway. The vast majority of cases are diagnosed and followed up in the community, butsome with extensive symptoms and large degree of reduced function are referred toregional Covid-clinics. In total this patient group is placing an enormous burden on thealready over stretched health care services. As the pandemic subsides the emerging threatof long-term disability from COVID remains to be quantified. Brain fog and cognitivesymptoms are common in long COVID in 30% of mild infections resulting in sick leave andloss of daily function, with women overrepresented among long COVID sufferers. The trueprevalence and underlying mechanisms of long COVID remains to be quantified. Althoughvaccination prevents severe infection and death, we have little knowledge on how best torehabilitate those who suffers from long COVID.Here we propose to develop knowledge on treatment interventions to counteract disabilityfrom long COVID and lessening the burden on health care services. We will conduct a studyof where we compare a short group intervention with systematic personalisedneurocognitive rehabilitation to document symptom alleviation. Our overarching goal is todevelop effective programmes for this evolving disease to reduce the suffering for thepatients, and thereby reducing costs for health services and society at large.
