Comparative features and outcomes of major neurological complications of COVID-19.

BACKGROUND AND PURPOSE: The aim of this study was to assess the neurological complications of SARS-CoV-2 infection and compare phenotypes and outcomes in infected patients with and without selected neurological manifestations. METHODS: The data source was a registry established by the European Academy of Neurology during the first wave of the COVID-19 pandemic. Neurologists collected data on patients with COVID-19 seen as in- and outpatients and in emergency rooms in 23 European and seven non-European countries. Prospective and retrospective data included patient demographics, lifestyle habits, comorbidities, main COVID-19 complications, hospital and intensive care unit admissions, diagnostic tests, and outcome. Acute/subacute selected neurological manifestations in patients with COVID-19 were analysed, comparing individuals with and without each condition for several risk factors. RESULTS: By July 31, 2021, 1523 patients (758 men, 756 women, and nine intersex/unknown, aged 16-101 years) were registered. Neurological manifestations were diagnosed in 1213 infected patients (79.6%). At study entry, 978 patients (64.2%) had one or more chronic general or neurological comorbidities. Predominant acute/subacute neurological manifestations were cognitive dysfunction (N = 449, 29.5%), stroke (N = 392, 25.7%), sleep-wake disturbances (N = 250, 16.4%), dysautonomia (N = 224, 14.7%), peripheral neuropathy (N = 145, 9.5%), movement disorders (N = 142, 9.3%), ataxia (N = 134, 8.8%), and seizures (N = 126, 8.3%). These manifestations tended to differ with regard to age, general and neurological comorbidities, infection severity and non-neurological manifestations, extent of association with other acute/subacute neurological manifestations, and outcome. CONCLUSIONS: Patients with COVID-19 and neurological manifestations present with distinct phenotypes. Differences in age, general and neurological comorbidities, and infection severity characterize the various neurological manifestations of COVID-19.

European Academy of Neurology 2019 - 2022.

BACKGROUND: The EAN was founded in 2014 with the mission of reducing the burden of neurological disorders. METHODS: In 2019 the society defined four strategic priorities: education, science, membership, and advocacy. This paper reviews the EAN development in the last 3 years. RESULTS: The outbreak of COVID-19 pandemic in 2020 had a profound impact on the entire world and triggered profound changes in the EAN including the implementation of new digital technologies. Education The virtual congress in 2020 was the best attended in history (43,844 registrations). The European Training Requirements for Neurology was revised. A mentorship program and a student section were created. A state-of-the-art eLearning platform will be launched in 2022. Research To assess neurological manifestations of COVID-19 an international registry (ENERGY) was created. Studies on the burden of neurological disorders and sleep disorders, respectively, were started. The first EAN science school took place in 2022. Membership The EAN includes 45,000 members and 47 national societies. New task forces were created on gender and diversity, tele- and general neurology. Advocacy In 2022 the EAN supported the adoption of the Global Action Plan on epilepsy and other neurological disorders by the WHO and the neurological community in the Ukraine. The same year the EAN launched a Brain Health Strategy promoting a non-disease and -age centred, lifelong holistic approach ('one brain, one life, one approach'). CONCLUSION: The ongoing pandemic and wars demonstrate the fragility of our political and health systems and the need for people centeredness, international collaborations, solidarity, and digitalization. The EAN will continue promoting excellence in neurological care, science and education as well as brain health for all.

Short- and long-term outcome and predictors in an international cohort of patients with neuro-COVID-19.

BACKGROUND AND PURPOSE: Despite the increasing number of reports on the spectrum of neurological manifestations of COVID-19 (neuro-COVID), few studies have assessed short- and long-term outcome of the disease. METHODS: This is a cohort study enrolling adult patients with neuro-COVID seen in neurological consultation. Data were collected prospectively or retrospectively in the European Academy of Neurology NEuro-covid ReGistrY ((ENERGY). The outcome at discharge was measured using the modified Rankin Scale and defined as 'stable/improved' if the modified Rankin Scale score was equal to or lower than the pre-morbid score, 'worse' if the score was higher than the pre-morbid score. Status at 6 months was also recorded. Demographic and clinical variables were assessed as predictors of outcome at discharge and 6 months. RESULTS: From July 2020 to March 2021, 971 patients from 19 countries were included. 810 (83.4%) were hospitalized. 432 (53.3%) were discharged with worse functional status. Older age, stupor/coma, stroke and intensive care unit (ICU) admission were predictors of worse outcome at discharge. 132 (16.3%) died in hospital. Older age, cancer, cardiovascular complications, refractory shock, stupor/coma and ICU admission were associated with death. 262 were followed for 6 months. Acute stroke or ataxia, ICU admission and degree of functional impairment at discharge were predictors of worse outcome. 65/221 hospitalized patients (29.4%) and 10/32 non-hospitalized patients (24.4%) experienced persisting neurological symptoms/signs. 10/262 patients (3.8%) developed new neurological complaints during the 6 months of follow-up. CONCLUSIONS: Neuro-COVID is a severe disease associated with worse functional status at discharge, particularly in older subjects and those with comorbidities and acute complications of infection.

Evaluation of the 2020 European Academy of Neurology virtual congress: transition from a face-to-face to a virtual meeting.

BACKGROUND AND PURPOSE: Due to the COVID-19 pandemic, scientific congresses are increasingly being organized as virtual congresses (VCs). In May 2020, the European Academy of Neurology (EAN) held a VC, free of charge. In the absence of systematic studies on this topic, the aim of this study is to evaluate the attendance and perceived quality of the 2020 EAN VC compared to the 2019 EAN face-to-face congress (FFC). METHODS: An analysis of the demographic data of participants obtained from the online registration was done. A comparison of the two congresses based on a survey with questions on the perception of speakers' performance, quality of networking and other aspects was made. RESULTS: Of 43,596 registered participants, 20,694 active participants attended the VC. Compared to 2019, the number of participants tripled (6916 in 2019) and the cumulated number of participants attending the sessions was five times higher (169,334 in 2020 vs. 33,024 in 2019). Out of active participants 55% were from outside Europe, 42% were board-certified neurologists (FFC 80%) and 21% were students (FFC 0.6%). The content of the congress was evaluated as 'above expectation' by 56% of the attendees (FFC 41%). Of the respondents who had been exposed to earlier EAN congresses 73% preferred the FFC compared to the VC (17%). CONCLUSION: The VC fulfilled the main mission of organizing high quality EAN congresses despite the restrictions of the impersonal format. The geographical distribution of the participants proves the expected higher inclusivity of a VC. The large participation of students and neurologists in training opens new educational potentials for the EAN.

Neurology training and research in the COVID-19 pandemic: a survey of the Resident and Research Fellow Section of the European Academy of Neurology.

BACKGROUND AND PURPOSE: The COVID-19 (SARS-CoV-2) outbreak has disrupted residency programmes due to university and hospitals' priorities to face this emergency at all cost. Most research projects and clinical trials were temporarily stopped or postponed. The Resident and Research Fellow Section (RRFS) of the European Academy of Neurology (EAN) has decided to assess the impact of the COVID-19 pandemic on neurology training. METHODS: All EAN RRFS members were invited to fill out an online questionnaire of 40 items concerning their clinical involvement during the COVID-19 emergency, and the impact of the pandemic on their training (Appendix S1). RESULTS: Of the 227 RRFS members who completed the questionnaire, 222 were from Europe, and of those 111 were from Portugal, Italy or France. Responders highlighted that severe restrictions have been imposed to face this pandemic, including reduction of inpatient beds, prohibition of in-person visits and limitation to hospital access for patients' relatives. This was accompanied by an increase in email correspondence and phone calls with 50% of countries allowing telemedicine to reach outpatients. Seventy-nine per cent of the respondents felt that the pandemic will probably have a serious impact on their training and career. CONCLUSION: The pandemic led to a disruption of neurology activities, including medical training and research. The long-run impact of these changes remains unknown, but it will probably change the way neurology practice and training will be organized for future generations.
