Brief Summary

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the seventh coronavirus known to infect humans, and causing coronavirus disease 2019 (COVID-19). . Since its emergence in December 2019, in Wuhan, China, SARS-CoV-2 has led to a global pandemic with almost 188 million cases and 4 million COVID-19 related deaths reported. Although initially considered as a predominantly acute respiratory illness, it soon became apparent that COVID-19 could also produce neurological manifestations and severe neurological complications. During the acute phase of SARS-CoV-2 infection, about 36% of cases develop neurological symptoms of which 25% can be attributed to the direct involvement of the central nervous system. There are increasing reports of central and peripheral nervous system involvement. Acute neurological manifestations reported, include, but are not limited to: anosmia, dysgeusia, stroke, encephalomyelitis, meningo-encephalitis, posterior reversible encephalopathy, acute necrotizing encephalopathy, new onset seizures and Guillain-Barre syndrome. However, one of the most perplexing aspects of SARS-CoV-2 is that two to four months after their initial (mostly apparently mild) infection, some COVID-19 patients still present a constellation of more chronic neurological symptoms colloquially known as "long COVID-19" syndrome. In these patients, COVID-19 appears to affect long-term brain function and patients have functional complaints as dyspnea, hyposmia/anosmia, dysgeusia/ageusia, but also, and more importantly, memory and cognitive impairment, pain, deadening fatigue, and alterations in sleeping-pattern/insomnia, all of them correlated with typical 18F-FDG brain PET scan abnormalities. At the beginning of the pandemic, the medical world was not expecting the phenomenon of COVID-19 patients developing persistent neurologically symptoms. However, more than one year after the pandemic, multiple waves of the "long COVID-19" syndrome may be expected to occur worldwide. To face the long tail impact of the COVID-19 pandemic on public health and its social and economic consequences on our society, future research urgently needs to be dedicated to these "long COVID-19" patients in an attempt to determine, understand and manage their symptoms. A lot of "long COVID-19" patients are desperately searching for help. This project found his origin in the fact that suddenly many patients spontaneously presented with a similar constellation of persistent (chronic) symptoms, months after they had (mostly mild) COVID-19, with many of them being relatively young, without underlying health problems, but unable to work due to cognitive impairment. During the entire study, the opinion and feelings of these patients will be taken in account, all the more so because the majority of these patients were initially left behind. The primary objective of this study is to determine the different types of neurological dysfunction and clinical manifestations of the "long COVID-19" syndrome and to correlate them to abnormalities/signs on cerebral perfusion scintigraphy. Furthermore, the investigators aim to determine and validate a specific imaging biomarker of post-COVID-19 encephalopathy. The secondary objective of this study is to determine the best therapeutic modality to treat and improve prognosis of patients with "long COVID-19" syndrome with defined central nervous system impairment.

Conditions

Long Covid19

Outcome Measures

Primary Outcomes (1)

• Difference (1 year versus baseline) in the distribution of hypo-perfused areas in the brain as assessed by cerebral perfusion scintigraphy.

  SPECT data were acquired using a standardized protocol. For focal abnormalities of increased or decreased uptake, the anatomical location was described.

Study Arms (1)

Long Covid19 patient group

EXPERIMENTAL

Patients with Long Covid19 undergoing perfusion brain scintigraphy

Diagnostic Test: Perfusion brain scintigraphy imaging

Interventions

Perfusion brain scintigraphy imaging DIAGNOSTIC_TEST

The cerebral perfusion scintigraphy via a SPECT examination aims to analyze the cerebral blood flow and detect possible lesions or inflammations.
