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.

Needs and Perceptions of Patients With Dystonia During the COVID-19 Pandemic: A Qualitative Framework Analysis of Survey Responses From Italy.

Introduction: The COVID-19 pandemic and its countermeasures have created changes in both life and healthcare. With the prioritization of COVID-19-related management, the risks and experiences of patients suffering from rare conditions, such as dystonia, during the pandemic remain understudied. Materials and Methods: Using a framework analysis of a nationwide qualitative online survey, we sought to explore the perspectives of patients with dystonia on their clinical assistance and possible unmet needs during the first pandemic wave. An online survey consisting of 37 items (such as demographic characteristics, dystonia-related features, neurological service provision, therapeutic relationship with the neurologist, perceptions related to virus infection, perceptions about healthcare-related needs, work-related questions, requesting information, and seeking support during the pandemic) was carried out using both close and open-ended questions. Results: Responses from 62 participants were collected, with most of them from the red zones in Italy, where they were confined indoors. Social isolation was a relevant stressor. Motor and non-motor symptoms increased with detrimental consequences for patients' job and daily functionality. Outpatient clinics and rehabilitation sessions were temporarily shut down, and even telephone/mail support was sparse. Despite efforts, patients felt alone in dealing with dystonia. Conclusion: The first wave of the pandemic and its related restrictions had detrimental consequences for people living with dystonia, and their relevant needs remained unmet. These findings may contribute to implementing remedial healthcare provisions in this pandemic or in future pandemics.

Being a technician during COVID-19: a qualitative cross-sectional survey on the experiences of clinical neurophysiology technicians.

BACKGROUND: During the Sars-CoV-2 virus pandemic, Italy faced an unrivaled health emergency. Its impact has been significant on the hospital system and personnel. Clinical neurophysiology technicians played a central role (but less visibly so compared to other healthcare workers) in managing the COVID-19 pandemic. This research aims to explore the experiences of clinical neurophysiology technicians during the pandemic and contribute to the debate on the well-being of healthcare workers on the front line. METHODS: We implemented a cross-sectional survey across Italy. It contained questions that were open-ended for participants to develop their answers and acquire a fuller perspective. The responses were analyzed according to the framework method. RESULTS: One hundred and thirty-one responses were valid, and the following themes were generated: technicians' experiences in their relationship with patients, technicians' relationship with their workgroup and directors, and technicians' relationship with the context outside of their work. The first theme included sub-themes: fear of infection, empathy, difficulty, a sense of obligation and responsibility, anger, and sadness. The second theme contained selfishness/solidarity in the workgroup, lack of protection/collaboration from superiors, stress, and distrust. The last theme included fear, stress/tiredness, serenity, sadness, and anger. CONCLUSION: This study contributes to building a humanized perspective for personnel management, bringing attention to the technical work of healthcare professionals in an emergency and the emotional and relational dimensions. These are the starting points to define proper, contextually adequate support.

COVID-19 and Parkinsonism: A Critical Appraisal.

A few cases of parkinsonism linked to COVID-19 infection have been reported so far, raising the possibility of a post-viral parkinsonian syndrome. The objective of this review is to summarize the clinical, biological, and neuroimaging features of published cases describing COVID-19-related parkinsonism and to discuss the possible pathophysiological mechanisms. A comprehensive literature search was performed using NCBI's PubMed database and standardized search terms. Thirteen cases of COVID-19-related parkinsonism were included (7 males; mean age: 51 years ± 14.51, range 31-73). Patients were classified based on the possible mechanisms of post-COVID-19 parkinsonism: extensive inflammation or hypoxic brain injury within the context of encephalopathy (n = 5); unmasking of underlying still non-symptomatic Parkinson's Disease (PD) (n = 5), and structural and functional basal ganglia damage (n = 3). The various clinical scenarios show different outcomes and responses to dopaminergic treatment. Different mechanisms may play a role, including vascular damage, neuroinflammation, SARS-CoV-2 neuroinvasive potential, and the impact of SARS-CoV-2 on α-synuclein. Our results confirm that the appearance of parkinsonism during or immediately after COVID-19 infection represents a very rare event. Future long-term observational studies are needed to evaluate the possible role of SARS-CoV-2 infection as a trigger for the development of PD in the long term.

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.

Parkinson's disease patients' needs during the COVID-19 pandemic in a red zone: A framework analysis of open-ended survey questions.

BACKGROUND AND PURPOSE: During the first phase of the COVID-19 pandemic, a lockdown was imposed in Italy. The aim of this study was to investigate the perceptions, feelings and unmet needs of Parkinson's disease (PD) patients who experienced the 2-month lockdown in a "red zone" in the northern part of Italy during the COVID-19 outbreak. METHODS: The study had a descriptive design that used a cross-sectional online survey which included open-ended questions to elicit responses on the participant's feelings concerning their risk of contracting coronavirus, how their physical activity had changed, and their personal needs, dictated by their condition, which were not met in this pandemic period as compared to previous periods. Demographic data were analysed using descriptive frequencies, while the open-ended questions were analysed using thematic framework analysis. RESULTS: The study included 103 participants (63 men/40 women [61.17 vs. 38.83%]). Framework analysis led to the identification of four main themes: (i) fearing the risk of contracting coronavirus; (ii) reduction of physical activity; (iii) perception of the risk of not being able to access outpatient clinics or support services; and (iv) negative experiences of the important reduction in socialization. The perceptions of unmet needs appeared to be greater than the actual experience, particularly for the reduction in physical activity and the interruption of contacts with the neurologist and other specialists. CONCLUSIONS: This study highlights how perceptions and actual experience shape the meaning of living with PD during the pandemic. Worth noting is the divergence between perceptions and real impact in some aspects of the COVID-19 outbreak.

Facial palsy during the COVID-19 pandemic.

OBJECTIVE: To compare the incidence and clinical features of individuals presenting in emergency rooms (ER) with facial palsy during the Italian COVID-19 outbreak and in the same period of 2019. METHODS: We retrospectively reviewed the medical records for all accesses to the six ER in the province of Reggio Emilia, Italy, during the first phase of the COVID-19 pandemic (27 February-3 May 2020) to identify all cases of diagnosed facial palsy. Clinical information was retrieved for each patient and compared with that of facial palsy cases presenting in 2019. RESULT: Between 27 February and 3 May 2020, 38 patients presented to provincial ERs for facial palsy; in 2019, there were 22 cases, for an incidence rate ratio of 1.73 (95% CI 1.02-2.92) for the 2020 cohort. Of the 2020 cohort, eight patients (21%) presented with active or recent symptoms consistent with COVID-19 infection, compared with 2 (9%) in 2019 (p = .299); one was tested and resulted positive for SARS-CoV-2. Moreover, patients were younger (-11 years, p = .037) than those of the previous year and manifested a longer lag (+1.1 days, p = .001) between symptoms onset and ER presentation. CONCLUSION: We observed a higher occurrence of facial palsy during the COVID-19 outbreak compared to the same period of the previous year; 21% of patients presenting with facial palsy had active or recent symptoms consistent with SARS-CoV-2 infection, suggesting an excess risk of facial palsy during or after COVID-19. These patients searched for medical attention later, probably because of the fear of contracting COVID-19 during assistance.

Frequency and outcome of olfactory impairment and sinonasal involvement in hospitalized patients with COVID-19.

BACKGROUND: Olfactory dysfunction has shown to accompany COVID-19. There are varying data regarding the exact frequency in the various study population. The outcome of the olfactory impairment is also not clearly defined. OBJECTIVE: To find the frequency of olfactory impairment and its outcome in hospitalized patients with positive swab test for COVID-19. METHODS: This is a prospective descriptive study of 100 hospitalized COVID-19 patients, randomly sampled, from February to March 2020. Demographics, comorbidities, and laboratory findings were analyzed according to the olfactory loss or sinonasal symptoms. The olfactory impairment and sinonasal symptoms were evaluated by 9 Likert scale questions asked from the patients. RESULTS: Ninety-two patients completed the follow-up (means 20.1 (± 7.42) days). Twenty-two (23.91%) patients complained of olfactory loss and in 6 (6.52%) patients olfactory loss was the first symptom of the disease. The olfactory loss was reported to be completely resolved in all but one patient. Thirty-nine (42.39%) patients had notable sinonasal symptoms while rhinorrhea was the first symptom in 3 (3.26%). Fifteen patients (16.3%) had a taste impairment. Patients with sinonasal symptoms had a lower age (p = 0.01). There was no significant relation between olfactory loss and sinonasal symptoms (p = 0.07). CONCLUSIONS: Sudden olfactory dysfunction and sinonasal symptoms have a considerable prevalence in patients with COVID-19. No significant association was noted between the sinonasal symptoms and the olfactory loss, which may suggest that other mechanisms beyond upper respiratory tract involvement are responsible for the olfactory loss.

Prothrombotic state induced by COVID-19 infection as trigger for stroke in young patients: A dangerous association.

•COVID-19 infection could led to a pro-inflammatory and pro-thrombotic state.•Cerebrovascular involvement may occur in COVID-19 infection even in young patients.•Physicians should be aware that stroke may be the first COVID-19 manifestation.
