Assessing the Usability of an Instagram Filter in Monitoring Essential Tremor: A Proof-of-Concept Study.

Background: Spiral drawing is an important test in monitoring essential tremor (ET). With the rise of telemedicine amid the coronavirus disease 2019 pandemic, a contactless tool for monitoring tremors was required. We aimed to assess the validity of a novel smartphone technology using a video-based social media platform for rapid and objective monitoring of ET. Methods: A prospective pilot study evaluated patients with ET in 2 clinic visits. Videos of tremors were recorded using a publicly available Instagram filter and were visually compared with spirals drawn by the patients. The level of agreement among the raters was evaluated. Results: A total of 12 patients with ET were recruited. A consensus between both raters was achieved for 11 patients (91.6%) for both spirals and videos with good interrater agreement (κ value, 0.755 ± 0.332). Conclusion: This novel method was found to be valid and easy to use in measuring ET in real-world settings. Further research in a larger cohort is needed to suggest its use as a home-based or clinic-based monitoring tool.

COVID-19 vaccination in people with multiple sclerosis, real-life experience.

BACKGROUND: Vaccination against the severe acute respiratory syndrome coronavirus type-2 (SARS-CoV-2) virus is recommended in multiple sclerosis (MS) to reduce the risk of complications from Coronavirus disease 2019 (COVID-19) infection. These vaccines were not investigated in people with MS (PWMS). OBJECTIVE: This study aimed to report the short-term safety of the COVID-19 vaccines among PWMS. METHODS: Pfizer-BioNTech mRNA (BNT162b2) vaccine and Oxford-Astra Zenecaa chimpanzee adenovirus-vectored (ChAdOx1 nCoV-19) vaccine have been approved to be used in Kuwait since December 2021. PWMS registered in Kuwait national registry were contacted by phone, WhatsApp, or through face-to-face interviews and were invited to complete our questionnaire. Demographic, clinical data, symptoms following the vaccine, worsening of pre-existing MS symptoms, and occurrence of relapse were recorded. RESULTS: Of the 820 PWMS, 647 completed the questionnaire. Between January 2021 and 31 August 2021, 383 (59.28%) PWMS received at least one dose of the approved vaccinations versus 63.4% of the general population on the same date. Their mean age was 36.82 + 8.80, and most of them, 247 (64.3%), were females. A total of 356 vaccinated cohorts (92.6%) were treated with disease-modifying therapies. Adverse events were reported by 261 (68.15%) subjects. One case of COVID-19 infection was encountered after the first dose of the BNT162b2 vaccine. Twenty-one (5.48%) cases reported worsening of pre-existing MS symptoms after the vaccine. Five patients (1.31%) reported relapse after the COVID-19 vaccine. The most common adverse events of the COVID-19 vaccine were pain at the injection site, fatigue, low-grade fever, and body ache; and resolved within one week. There was no significant association between use of disease modifying therapy (DMT) and COVID-19 vaccine adverse events. CONCLUSION: BNT162b2 and ChAdOx1 nCoV-19 are safe for PWMS. No increased risk of relapse activity or worsening of pre-existing MS symptoms.

Prevalence, severity, outcomes, and risk factors of COVID-19 in multiple sclerosis: An observational study in the Middle East.

A cross-sectional hospital records-based study was conducted to evaluate the prevalence, severity, outcomes, and identify demographic and clinical risk factors of coronavirus disease (COVID-19) in patients with MS. The study was conducted at multiple clinics in Oman, Kuwait, and the United Arab Emirates (UAE) from March 2020 to February 2021. The association of patient demographics, MS disease characteristics, and use of disease-modifying therapies with outcomes of COVID-19 illness were evaluated using odds ratio. A total of 134 MS patients with COVID-19 (prevalence rate of 3.7%) having a median age of 35.5 years were analyzed in the study. A majority (126 [94.0%]) of patients had mild COVID-19 illness and 122 (91.0%) made a full recovery, while 1 (0.7%) patient died. The median EDSS score reported in the study was low (1.0). Univariate regression analysis showed high EDSS scores, progressive MS disease, and use of anti-CD20 therapy such as rituximab as risk factors for moderate to severe COVID-19 requiring hospitalization. Comorbidities were associated with a higher risk of non-recovery from COVID-19 in both univariate and multivariate analyses. Age, sex, smoking history, and duration of MS did not show a significant association with severity or adverse COVID-19 disease outcome. Identification of risk factors can aid in improving the treatment and monitoring of pwMS and COVID-19.

Effect of Pre-exposure Use of Amantadine on COVID-19 Infection: A Hospital-Based Cohort Study in Patients With Parkinson's Disease or Multiple Sclerosis.

Background: Amantadine has been proposed to inhibit E-channel conductance in reconstituted lipid bilayers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We aimed to study whether patients on amantadine have altered risks of contracting COVID-19 infection. Methods: We conducted a hospital-based, observational, retrospective cohort study using data for patients on amantadine supported by data given by the patients through an online questionnaire. We included registered amantadine users in our hospital for 6 months or more on March 1, 2020, and non-amantadine users to act as the control group. We used forced entry, multiple logistic regression models to estimate adjusted ORs for amantadine adjusting for the confounders. Findings: Between September 1, 2019, and March 1, 2020, 212 patients with Parkinson's disease (PD) or multiple sclerosis (MS) received greater than one equal to two prescriptions of amantadine. We selected a random sample of diagnoses which matched 424 patients of non-amantadine users (1:2) as a control group (424 patients). Between March 1, 2020, and March 1, 2021, 256 patients responded to our online questionnaire, 87 patients were on amantadine (group I), and 169 patients were not (control group, group II). COVID-19 disease infection proved to be 5.7 and 11.8% in group I and II patients, respectively. Increased odds of COVID-19 in multivariable-adjusted models were associated with old age and history of contact with COVID cases. Amantadine was associated with a significantly reduced risk of COVID-19 disease infection (adjusted OR 0.256, 95% CI 0.074-0.888). Interpretation: Amantadine is associated with a reduced risk of COVID-19 infection after adjusting for a broad range of variables. History of contact with COVID cases and old age are risk factors for COVID-19 infection. Therefore, we recommended randomized clinical trials investigating amantadine use for the prevention of COVID-19.

Coronavirus disease-19 and headache; impact on pre-existing and characteristics of de novo: a cross-sectional study.

BACKGROUND: Coronavirus disease-19 is caused by the severe acute respiratory syndrome coronavirus 2 Headache is a common symptom during and after Coronavirus disease-19. We aimed to study headache character in relation to COVID-19. METHODS: This was a cross-sectional study. Patients who had Coronavirus disease-19, confirmed by reverse transcription polymerase chain reaction technique and presented to the headache clinic within 3 months after the onset of infections were identified to the study. Study included patients diagnosed as primary headache disorders according to The International Classification of Headache Disorders, 3rd edition. Participants were grouped into categories according to having previous or de novo headache. Descriptive data, paired sample t-test and the chi-squared test (X2) were used for statistical analyses of the data. RESULTS: A total of 121 patients were included in this study. Their mean age was 35.29 + 9.54 and most of them were females (83.5%). Prior to Coronavirus disease-19 infections, 78 (64.5%) had migraine and 11(9.1%) experienced a tension-type headache while 32 (26.4) reported de novo headache post Coronavirus disease-19. Patient had significant increase in headache days 11.09 ± 8.45 post Coronavirus disease-19 compared with 8.66 ± 7.49 headache days before Coronavirus disease-19 infection (p < 0.006). Post Coronavirus disease-19, the usage of analgesic increased significantly by the patient with migraine (2.31 ± 1.65 vs 3.05 ± 2.09, p = 0.002) while the patient with tension type headache had statistically significant increase in severity (5.556 ± 1.86 vs 7 ± 2.25, p = 0.033) and frequency (7 ± 6.29 vs 12.72 ± 7.96, p = 0.006) of headache attacks. Bi-frontal and temporal headache are the most reported (40.6% each) headache site among de novo headache group. Patients younger than 40 years had longer duration of the headache attack (18.50 ± 16.44 vs 5.5 ± 9.07, p = 0.045) post COVID-19. Male patients compared to females (8.66 ± 1.15 versus 5.93 ± 2.01 p = 0.04) had more severe headache post Coronavirus disease-19. De novo headache resolved within 1 month in most of patients (65.3%). CONCLUSION: Primary headache get worse after Coronavirus disease-19. De novo primary headache is frequent post Coronavirus disease-19 and resolve within 1 month. Headaches related to Coronavirus disease-19 are severe, present as migraine phenotype. Young male patients with Coronavirus disease-19 tend to have worse headache.

A case report of multiple sclerosis after COVID-19 infection: causality or coincidence?

Introduction Since the declaration of COVID-19 pandemic, several cases of demyelination of both peripheral and central nervous systems have been reported. The association of viral infection and the development of CNS demyelination has long been studied, and this link has recently been reported following SARS-CoV-2 infection as well. Case report We report a case of a 36-year-old male who developed CNS demyelinating disease, that fulfilled the diagnostic criteria of multiple sclerosis (MS), 2 months after laboratory-confirmed infection with SARS-CoV-2. Conclusion To our knowledge, this is the second published case report of MS in association with COVID-19 infection, and the first case from Middle East and North Africa (MENA) region, adding to the growing literature of a probable causal relationship between SARS‐CoV‐2 infection and the development of MS.

Safety and tolerability of the novel 2019 coronavirus disease (COVID-19) vaccines among people with epilepsy (PwE): A cross-sectional study.

BACKGROUND: People with epilepsy (PwE) were concerned about the safety of the novel 2019 Coronavirus Disease (COVID-19) vaccines. OBJECTIVE: This study aimed to assess the side effects experienced by PwE following vaccination with COVID-19 vaccines and to identify the causes of vaccine hesitation. METHODS: We administered a questionnaire to PwE, who visited the epilepsy clinic at Ibn Sina Hospital in Kuwait during the first two working weeks of April 2021. It included socio-demographic, epilepsy status, and vaccination data. In addition, we asked those who were not vaccinated yet about the reasons and their plan. RESULTS: A total of 111 PwE were surveyed, with 82 being vaccinated and 29 being unvaccinated. Out of the 82 vaccinated, 66 (80.5%) reported at least one side effect. Patients who received the Pfizer BioNTech mRNA vaccine (BNT162b2) (first, second dosage); and the Oxford-AstraZenecaa chimpanzee adenovirus-vectored vaccine (ChAdOx1nCoV-19) (first dose) had the following reactions: Pain at the injection site (40%, 67.6%), 43.8%, fatigue (47%, 32.4%), 46.9%, Headache (33.3%, 35.3%), 34.4% and Myalgia (40%, 35%), 50% respectively. Local site effects, including pain (67.6% vs. 40%, p = < 0.001) and redness (26.5% vs 6.7%, p = 0.019), were more statistically significantly after the second dose of BNT162b2 vaccine compared to the first dose of the same vaccine. While there was no significant difference in systemic side effects frequencies between the two doses of the BNT162b2 vaccine. The systemic side effects were more statistically significantly after the first dose of ChAdOx1nCoV-19 compared to the first dose of the BNT162b2 vaccine and those included fever (56.3% vs 13.3%, p = < 0.001), chills (37.5% vs 6.7%, p = < 0.001), myalgia (50% vs 40%, p = < 0.001) and arthralgia (25% vs 6.7%, p = 0.021). The local site reactions were not significantly different between the first doses of both vaccines. Among the subgroup who had vaccine-related side effects, 66.7% were females, 90.9% were 55 or younger, 63.6% were on polytherapy, 74% had side effects for one day or less, and 95% were symptoms free by the end of the first-week post-vaccination. Symptoms were mild in 68% of the patients and moderate in 29.3%. Most patients (93.9%) did not report seizure worsening after vaccination. The relative risk of seizure worsening after the first and second doses of BNT162b2 and the first dose of ChAdOx1nCoV-19 vaccines was 1.027 (95% CI 0.891-1.183), 1.019 (95% CI 0.928-1.119), and 1.026 (95% CI 0.929-1.134) respectively. After the first dose of BNT162b2, one patient reported the development of status epilepticus. Among the non-vaccinated group, 34.9% were still indecisive, while 37.9% rejected the vaccination. Fear of adverse effects (42.9%) and fear of epilepsy worsening (23.8%) were the main reasons for vaccine hesitation. CONCLUSIONS: This study shows that the two vaccines under consideration (BNT162b2 and ChAdOx1nCoV-19) have a good safety profile and a low risk of epilepsy worsening among a cohort of PwE in Kuwait.

Unexplained worsening of parkinsonian symptoms in a patient with advanced Parkinson's disease as the sole initial presentation of COVID-19 infection: a case report.

BACKGROUND: Parkinson's disease (PD) is a neurodegenerative condition that has been reported following viral infections in rare occasions. Several neurological complications have emerged in association with coronavirus disease 2019 (COVID-19), since its declaration as a pandemic. Herein, we present a novel case of unexplained worsening of PD as the sole initial presentation of COVID-19, in the absence of fever or respiratory symptoms. CASE PRESENTATION: A 56-year-old male with advanced PD presented with severe rigidity, dystonic posturing of both feet, and confusion of 4 days duration. His condition progressed to an akinetic-rigid state and confusion during the following week, and a routine nasopharyngeal swab tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the 9th day of onset. He developed fever and dyspnea later and was intubated on the 10th day. CONCLUSION: To our knowledge, worsening of PD symptoms as the sole initial manifestation of SARS-CoV-2 infection, in the absence of other cardinal features of COVID-19, has not been reported in the literature. We suggest testing for COVID-19 infection in patients with PD, especially advanced cases, who present with unexplained worsening of symptoms, even in the absence of COVID-19 cardinal features.

Physicians' attitude towards webinars and online education amid COVID-19 pandemic: When less is more.

BACKGROUND: Since the declaration of COVID-19 as a pandemic, all scientific medical activities were shifted to an online format, in the form of webinars, to maintain continuing medical education (CME). We aimed to assess physicians' attitude among different medical specialties towards this sudden and unexpected shift of traditional face-to-face meetings into webinars, and to suggest future recommendations. METHODS: We conducted a cross-sectional, internet-based survey study using a 25-item questionnaire, from November 1 and November 15, 2020. The survey was created and distributed to physicians from different medical and surgical specialties and from different countries via several social media platforms, using a snowball technique. RESULTS: A total of 326 physicians responded; 165 (50.6%) were females, mean age of responders was 38.7 ± 7.5 years. The majority of responses (93.2%) came from Arab countries. Of them, 195 (59.8%) reported attending more webinars compared to the same period last year, with average of 3 per month. As regard to the general impression; 244 (74.8%) were "strongly satisfied" or "satisfied", with the most satisfaction for "training courses: by 268 (82.2%), and "International conferences" by 218 (66.9%). However, 246 respondents (75.5%) felt overwhelmed with the number and frequency of webinars during the pandemic, 171 (52.5%) reported attending less than 25% of webinars they are invited to, 205 (62.8%) disagreed that webinars can replace in-person meetings after the pandemic, and 239 (73.3%) agreed that online meetings need proper regulations. CONCLUSIONS: Webinars comprised a major avenue for education during COVID-19 pandemic, with initial general satisfaction among physicians. However, this paradigm shift was sudden and lacked proper regulations. Despite initial satisfaction, the majority of physicians felt overwhelmed with the number and frequency of webinars. Physicians' satisfaction is crucial in planning future educational activities, and considering that this current crisis will most likely have long lasting effects, webinars should be viewed as complementing traditional in-person methods, rather than replacement. In this study, we are suggesting recommendations to help future regulation of this change.

Association of COVID-19 Pandemic and Rate of Cognitive Decline in Patients with Dementia and Mild Cognitive Impairment: A Cross-sectional Study.

Introduction: Since the declaration of coronavirus disease 2019 (COVID-19) as a pandemic, patients with dementia, were specifically vulnerable to the negative impact of the outbreak. Objective: To examine the association between lockdown amid COVID-19 pandemic and the rate of cognitive decline among patients with dementia and mild cognitive impairment (MCI). Methods: We conducted a cross-sectional observational study on patients with dementia and MCI who attended the outpatient clinic at Ibn Sina Hospital, the main tertiary neurology center in Kuwait, during the month of September 2020. The rate of cognitive decline, estimated by MMSE scores, was compared between the period prior to, and during lockdown. Results: We evaluated 36 consecutive patients with cognitive impairment (23 females [63.9%], mean age 71 ± 10.8 years, mean disease duration 34.6 ± 29 months). Eleven patients (30.6%) progressed to a more severe stage during the study period; 1 MCI (2.8%) converted to mild dementia, 6 (16.6%) mild to moderate, and 4 (11.1%) moderate to severe dementia. Monthly decline of MMSE scores before lockdown was 0.2 ± 0.1 points, while it was 0.53 ± 0.3 points during lockdown, which was statistically significant (p = .001). The most affected cognitive domain was the memory with a mean decline of 1.5 ± 0.8 points. Conclusions: This study provides "real-world" data suggesting rapid cognitive decline in patients with dementia during the lockdown period. Healthcare systems should pay more attention to this vulnerable group, to help them maintain their mental, physical and social well-being during this crisis.

The effects of coronavirus disease 2019 (COVID-19) pandemic on people with epilepsy (PwE): an online survey-based study.

During the unprecedented COVID-19 pandemic in 2020, the whole world faced an unusual health emergency. Medical care of chronic neurological diseases, such as Epilepsy, is being neglected. In this survey, we aimed to evaluate the impact of the COVID-19 pandemic on the care of people with Epilepsy (PwE) and to identify their risk factors for seizure worsening to direct better future medical care. We administered a web-based survey (submitted on August 5, 2020). It included socio-demographic, Epilepsy-related, and psychometric data (The Depression, Anxiety, and Stress Scale-21 Items(DASS21) and The Pittsburgh Sleep Quality Index (PSQI). Regression analysis identified predictors of seizure worsening. We collected responses from an online survey of PwE during the pandemic. Out of 151 responders, 71 patients complained of issues related to Epilepsy management and all of whom reached the treating physician and solved their problems. Sleep quality was compromised in 84 patients (55.6%). Two-thirds of the patients in our cohort (66.2%) reported depression, 72.2% reported anxiety, and 75.5% reported stress. Eight patients (5.3%) got COVID-19 infection, and only one patient suffered from mild worsening of the seizure. The main concerns were shortage of medications for 46 (30.5%) patients, getting Coronavirus infection for 67 (44.4%) patients, and seizure worsening for 32 (21.3%) patients. Thirty-five patients (23.2%) reported seizure worsening, which was best explained by retirement or jobless state, having moderate or severe stress, poor sleep quality, vagus nerve stimulation (VNS), fear of getting COVID-19 infection, fear of worsening of seizures, or shortage of medication. During the current COVID-19 pandemic, a significant percentage of PwE experienced worsening of their seizures. This unusual, challenging experience clarifies the urgent need to establish telemedicine services and home-based management of Epilepsy, including ambulatory EEG, home video, and medication delivery to patients' homes to provide continuous medical care.

Impact of coronavirus disease 2019 (COVID-19) pandemic on patients with migraine: a web-based survey study.

BACKGROUND: Since the declaration COVID-19 as a pandemic, healthcare systems around the world have faced a huge challenge in managing patients with chronic diseases. Patients with migraine were specifically vulnerable to inadequate medical care. We aimed to investigate the "real-world" impact of COVID-19 pandemic on migraine patients, and to identify risk factors for poor outcome. METHODS: We administered an online, self-reported survey that included demographic, migraine-related, COVID-19-specific and overall psychosocial variables between July 15 and July 30, 2020. We recruited a sample of patients with migraine from headache clinic registry and via social media to complete an anonymous survey. Outcomes included demographic variables, change in migraine frequency and severity during the lockdown period, communication with treating physician, compliance to migraine treatment, difficulty in getting medications, medication overuse, symptoms of anxiety and/or depression, sleep and eating habits disturbance, screen time exposure, work during pandemic, use of traditional medicine, effect of Botox injection cancellation, and overall worries and concerns during pandemic. RESULTS: A total of 1018 patients completed the survey. Of the respondents, 859 (84.3%) were females; 733 (71.9%) were aged 20 to 40 years, 630 (61.8%) were married, and 466 (45.7%) reported working during the pandemic. In comparison to pre-pandemic period, 607 respondents (59.6%) reported increase in migraine frequency, 163 (16%) reported decrease in frequency, and 105 (10.3%) transformed to chronic migraine. Severity was reported to increase by 653 (64.1%) respondents. The majority of respondents; 626 (61.5%) did not communicate with their neurologists, 477 (46.9%) reported compliance to treatment, and 597 (58.7%) reported overuse of analgesics. Botox injections cancellation had a negative impact on 150 respondents (66.1%) from those receiving it. Forty-one respondents (4%) were infected with COVID-19; 26 (63.4%) reported worsening of their headaches amid infection period. Sleep disturbance was reported by 794 (78.1%) of respondents, and 809 (79.5%) reported having symptoms of anxiety and/or depression. CONCLUSIONS AND RELEVANCE: COVID-19 pandemic had an overall negative impact on patients with migraine. Several risk factors for poor outcome were identified. Long-term strategies should be validated and implemented to deliver quality care for patients with migraine, with emphasis on psychosocial well-being.
