Experience with telemedicine in neuromuscular clinic during COVID-19 pandemic.

Objectives: The aim of the present study was to evaluate the feasibility and acceptability of telehealth for the care of neuromuscular patients during the COVID-19 pandemic. Methods: Neuromuscular patients or their caregivers, as well as health care providers (HCPs), who completed a televisit during the pandemic received an online survey, assessing satisfaction with the visit, quality of care, and experience with the televisit interference. Results: Surveys from 46 neuromuscular patients (including 18 with motor neuron disease [MND])/caregivers and 7 HCPs were completed. Several aspects of televisits including good communication, adequate time to discuss concern, provision of equal care, and telemedicine interference were rated favorably among participants. Telehealth was strongly satisfactory in 30 (65.22%) and satisfactory in 15 (32.61%) neuromuscular patients/caregivers. In 18 MND patients, this was 10 (55.56%) and 7 (38.89%), respectively. Moreover, 24 (52.17%) neuromuscular patients/caregivers would strongly agree and 18 (39.13%) would agree to participate again in televisits. This was 10 (55.56%) and 4 (33.33%) for MND cases, respectively. Various medical issues were addressed during the televisits including medication management, ordering tests/referrals, discussion of goals of care, and research. The predictive stepwise logistic model found younger age as a predicting factor for higher satisfaction from, or participation again in, televisits in neuromuscular patients. Limb onset location was also a predicting factor for strong satisfaction from televisits in MND cases. Conclusions: Telemedicine is feasible and highly effective at achieving personalized care that was rated satisfactory by the majority of neuromuscular patients/caregivers and HCPs during the COVID-19 pandemic.

Post-Vaccination/Post-COVID Immune-Mediated Demyelination of the Brain and Spinal Cord: A Novel Neuroimaging Finding.

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19), which not only produces respiratory symptoms but is known to involve almost every system, and its neuroinvasive properties have been well demonstrated throughout the pandemic. Also, to combat the pandemic, there was rapid development and induction of various vaccination drives, following which many adverse events following immunization (AEFIs) have been reported, which include neurological complications as well. Method: We present a series of three cases, post vaccination, with and without a history of COVID illness that showed remarkably similar findings on magnetic resonance imaging (MRI). Result: A 38-year-old male presented with complaints of weakness of the bilateral lower limbs with sensory loss and bladder disturbance a day after receiving his first dose of ChadOx1 nCoV-19 (COVISHIELD) vaccine. A 50-year-old male with hypothyroidism characterized by autoimmune thyroiditis and impaired glucose tolerance experienced difficulty in walking 11.5 weeks after being administered with COVID vaccine (COVAXIN). A 38-year-old male presented with subacute onset progressive symmetric quadriparesis 2 months after their first dose of a COVID vaccine. The patient also had sensory ataxia, and his vibration sensation was impaired below C7. All three patients had typical pattern of involvement of the brain and spine on MRI with signal changes in bilateral corticospinal tracts, trigeminal tracts in the brain, and both lateral and posterior columns in the spine. Conclusion: This pattern of brain and spine involvement on MRI is a novel finding and is likely a result of post-vaccination/post-COVID immune-mediated demyelination.

Primary lateral sclerosis natural history study - planning, designing, and early enrollment.

Introduction/Aims. Primary lateral sclerosis (PLS) is exceedingly rare and has been an enigmatic disease. Recent progress has drastically changed this perception, with early biomarkers being investigated and potential medications for PLS emerging at the preclinical stage. The aim of this paper is to describe a study of PLS natural history and discuss the limitations and proposed solutions to the study of a rare and slowly progressive disease. Methods. The PLS Natural History Study is a 30-site, 24-month, prospective study that is supported by multiple funding sources. The study aims to enroll 50 early PLS (disease duration ≤4 years) and 50 definite PLS (disease duration 4 to 15 years) participants using modified PLS Diagnostic Criteria. Smartphone-based assessments including semi-quantitative and quantitative measures and patient-reported outcomes are utilized. In-person quantitative measures are also completed during site visits. The change in the PLS Functional Rating Scale score is the primary outcome. The study utilizes the NeuroBANK® patient-centric data capture and management platform. The biostatistical analysis plan has been developed. Results. In one year, 28 participants have been recruited. Enrollment has been much slower than anticipated due to the COVID-19 pandemic, the rarity of PLS, and potential study competition for internal resources from ALS clinical trials. Discussion. We discuss the need for more innovative methods to enroll and study individuals with such rare diseases and propose a number of mechanisms by which more efficient enrollment could be facilitated.
