Alzheimer’s disease (AD) is a neurodegenerative disorder that accounts for 60%–70% of patients with dementia, and it is estimated that over one million Canadians will be living with dementia by 2030. Disease-modifying therapies (DMTs) targeting the underlying pathophysiology of AD are currently in development. Several models have demonstrated that the potential arrival of Alzheimer’s DMTs will most likely overwhelm the already-constrained Canadian healthcare system. Canada does not have a strategy to address the extensive requirements of using DMTs, including providing an early diagnosis of AD, confirming DMT eligibility via amyloid biomarkers, and conducting ongoing treatment monitoring. Thus, a multidisciplinary group of experts involved in AD care in Canada gathered to review (1) the current barriers to diagnosis and management of AD; (2) how existing clinic models, including those used in multiple sclerosis (MS), could be applied to address key barriers in AD; and (3) how to design and implement optimal care pathways in the future. The actions outlined in this review will help clinicians and healthcare systems improve readiness to integrate the use of disease-modifying therapies in Alzheimer’s disease, if such therapies are approved in Canada.

Rapid advances in neurotechnology and neurosurgery are positioned to revolutionize care for patients suffering from debilitating neurological and psychiatric disease. Enthusiasm for the adoption of these technologies is tempered by ethical dilemmas regarding resource allocation, provision of care, communication with patients and other providers, and other potential pitfalls. In the present work, we discuss bioethical implications of novel neurotechnologies for medical practice. In particular, we examine the implications of neurotechnological advancement through the lens of professional communication. Emerging challenges within this domain are presented in the context of physician interactions with four key partners: (i) patients; (ii) other physicians; (iii) industry; and (iv) society-at-large. Anticipated issues as well as mitigation strategies are discussed as they relate to communication with these stakeholders.

Advance care planning (ACP) is a process to understand and communicate one’s wishes, values, and preferences for future medical care. As part of the Choosing Wisely Canada “Time to Talk” initiative, the Canadian Neurological Society (CNS) endorsed the creation of a working group to propose ACP recommendations for patients with neurological illness. A narrative review of primary literature on ACP in neurological and non-neurological illness, medical society guidelines, and publications by patient advocacy groups was conducted. Eight ACP recommendations were deemed relevant and important to Canadian neurology practice and were approved by the CNS Board of Directors. The recommendations are meant to serve as guidance for Canadian neurologists, to stimulate discussion about ACP within the Canadian neurology community, and to encourage neurologists to engage in ACP conversations with their patients.

During the COVID-19 pandemic, the Division of Neurology at BC Children’s Hospital rapidly transitioned to almost exclusively virtual health. In April 2020, 96% of outpatient visits were done virtually (64%) or by telephone, and only 4.2% were in-person. Total clinic visit numbers were unchanged compared to previous months. Neurologists reported high satisfaction with the virtual history and overall assessment, while the physical examination was less reliable. Additional in-person visits were rarely required. Rapid, sustained adoption of virtual health is possible in a pediatric neurology setting, providing reliable care that is comparable to in-person consultations when physical distancing is necessary.

Among healthy volunteers in psychiatric brain functional magnetic resonance imaging (fMRI) research studies, the prevalence of incidentalomas can be as high as 34%, of which 10% show clinical significance. An incidentaloma is a lesion found by coincidence without clinical symptoms or suspicion. Like lesions and other types of accidental findings, it is found in healthy individuals recruited to take part in psychiatric studies. The prevalence of these accidental findings among specific psychiatric populations remains unknown. However, a precise understanding of cerebral neuroanatomy, neuroradiological expertise, and an appropriate choice of fMRI exploration sequences will increase the sensitivity of identifying these accidental findings and enable researchers to address their clinical relevance and nature. We present recommendations on how to appropriately inform patients or participants of the accidental findings. Additionally, we propose specific suggestions pertaining to the clinical research setting aimed for investigators and psychiatrists. Unlike current articles pertaining to incidentaloma, the current report provides a distinct focus on psychiatric issues and specific recommendations for studies involving psychiatric patients.

Advances in high-resolution ultrasound have provided clinicians with unique opportunities to study diseases of the peripheral nervous system. Ultrasound complements the clinical and electrophysiology exam by showing the degree of abnormalities in myopathies, as well as spontaneous muscle activities in motor neuron diseases and other disorders. In experienced hands, ultrasound is more sensitive than MRI in detecting peripheral nerve pathologies. It can also guide needle placement for electromyography exam, therapeutic injections, and muscle biopsy. Ultrasound enhances the ability to detect carpal tunnel syndrome and other focal nerve entrapment, as well as pathological nerve enlargements in genetic and acquired neuropathies. Furthermore, ultrasound can potentially be used as a biomarker for muscular dystrophy and spinal muscular atrophy. The combination of electromyography and ultrasound can increase the diagnostic certainty of amyotrophic lateral sclerosis, aid in the localization of brachial plexus or peripheral nerve trauma and allow for surveillance of nerve tumor progression in neurofibromatosis. Potential limitations of ultrasound include an inability to image deeper structures, with lower sensitivities in detecting neuromuscular diseases in young children and those with mitochondrial myopathies, due to subtle changes or early phase of the disease. As well, its utility in detecting critical illness neuromyopathy remains unclear. This review will focus on the clinical applications of neuromuscular ultrasound. The diagnostic values of ultrasound for screening of myopathies, neuropathies, and motor neuron diseases will be presented.

Neuromuscular ultrasound is a rapidly evolving technique for diagnosing, monitoring and facilitating treatment of patients with muscle and nerve disorders. It is a portable point-of-care technology that is non-invasive, painless and without ionizing radiation. Ultrasound can visualize muscle texture alterations indicating dystrophy or denervation, changes in size and anatomic continuity of nerve fascicles, and its dynamic imaging capabilities allow capturing of contractions and fasciculations. Ultrasound can also provide real-time guidance for needle placement, and can sometimes make a diagnosis when electromyography is not tolerated or not informative anymore. This review will focus on the technical and practical aspects of ultrasound as an imaging technique for muscles and nerves. It will discuss basic imaging principles, hardware and software setup, and provide examples of ultrasound use for visualizing muscle and nerve abnormalities with accuracy and confidence. The review is intended as a practical “how-to” guide to get started with neuromuscular ultrasound in daily practice.

Background: Patient-centered care for individuals with myotonic dystrophy (DM1) and Huntington’s disease (HD)—chronic, progressive, and life-limiting neurological conditions—may be challenged by patients’ cognitive and behavioral impairments. However, no research has explored health care providers’ (HCPs’) perspectives about patient-centered care provision for these patients along their disease trajectory. Methods: Constructivist grounded theory informed the iterative data collection and analysis process. Eleven DM1 or HD HCPs participated in semistructured interviews, and three stages of coding were used to analyze their interview transcripts. Codes were collapsed into themes and categories.Results: Three categories including an evolving care approach, fluid roles, and making a difference were identified. Participants described that their clinical care approach evolved depending on the patient’s disease stage and caregivers’ degree of involvement. HCPs described that their main goal was to provide hope to patients and caregivers through medical management, crisis prevention, support, and advocacy. Despite the lack of curative treatments, HCPs perceived that patients benefited from ongoing clinical care provided by proactive clinicians. Conclusions: Providing care for individuals with DM1 and HD is a balancing act. HCPs must strike a balance between (1) the frustrations and rewards of patient-centered care provision, (2) addressing symptoms and preventing and managing crises while focusing on patients’ and caregivers’ quality of life concerns, and (3) advocating for patients while addressing caregivers’ needs. This raises important questions: Is patient-centered care possible for patients with cognitive decline? Does chronic neurological care need to evolve to better address patients’ and caregivers’ complex needs?

Background: Anticholinergic and sedating medications are generally contraindicated in those with cognitive decline. We examined trends in medication use by patients at initial presentation to a rural and remote memory clinic (RRMC) between March 2004 and June 2015 to determine whether patterns of medication use have changed. Methods: The first 444 patients seen at the RRMC between 2004 and 2015 were included in this analysis. Medication lists were collected at the patient’s initial visit, and it was noted whether patients were taking anticholinergic or potentially sedating drugs. Statistical analysis (Spearman’s correlation) was conducted to examine trends in medication use over time. Results: Patients were on a mean of 5.18 medications (standard deviation, 3.46). Ninety-one patients (20.5%) were taking at least one anticholinergic medication. There was a decline (25.0% in 2004 to 12.5% in 2014) in percentage of patients presenting with anticholinergic medications over the 11 years of this study (Spearman’s correlation coefficient =−0.64, p=0.035). The prevalence of drugs acting on the central nervous system trended toward an increase, but this was not statistically significant. Sixty-three patients (14.2%) presented to the RRMC already taking a cholinesterase inhibitor. Conclusions: The most encouraging statistic to come from this study is a decline in anticholinergic medication use in this rural population. Prescribers must be properly informed to ensure that the number of medications per patient does not continue to rise, that medications are used only as necessary, and that potentially deleterious medications are avoided.

Background: Amyotrophic lateral sclerosis (ALS) is a rapidly progressing degenerative motor neuron disease that results in significant muscle weakness. Defects in energy metabolism and difficulties in swallowing eventually lead to a reduction in body mass. Weight loss exacerbates symptoms and serves as an independent negative prognostic factor. Percutaneous endoscopic gastrostomy (PEG) is often inserted in patients with ALS to either supplement or replace oral feeding. However, the criteria for PEG placement and timing of insertion are important clinical decisions that have not been fully studied. Given the absence of guiding evidence, the aim of this project was to better understand how Canadian ALS clinics make decisions regarding gastrostomy feeding. Methods: ALS clinical directors across Canada were asked if they had written guidelines for timing of PEG insertion and if not, what criteria they use to make this decision. Responses from 10 of 17 centres contacted were received. Results: The approach to supplemental nutrition management in Canadian clinics varies in the absence of formal guidelines. Only one centre has a written set of centre-specific protocols in place. Most clinics considered some combination of respiratory decline, weight loss, dysphagia and/or patient readiness when reaching a decision. However, the absolute threshold and mechanism of measuring the individual criteria differed between clinics. Conclusions: Practices generally reflect international published recommendations but vary on the emphasis of specific criteria. Further research is required to determine the optimal timing and criteria to place gastrostomy feeding tubes in the ALS population.

Background: The Canadian Neurological Society commissioned a manpower survey in 2012 to assess Canadian neurological manpower and resources.Methods: Surveys were sent electronically to all Canadian neurologists with available email addresses. Responses were analysed for effects of physician gender, age, geographic location (eastern or western Canada) or type of practice (academic, community). Questions focused on work patterns, neurologic conditions treated, access to or performance of procedures, and service and manpower issues.Results: A total of 694 of 854 neurologists in Canada were surveyed and 219 (32%) responded. Respondents were 70% male with mean age of 50 years. Neurologists worked an average of 57 hours/week and saw a mean of 40 patients per week. There were significant differences in number of patients seen, types of practice, and areas of neurological specialization between community and academic neurologists. Fifty percent of neurologists report shortages of neurologists in their community, particularly of general adult neurologists. Wait times for neurological services exceeded international standards for consultations and also were longer than Canadian averages for other specialists. More community (18%) than academic (5%) neurologists planned to retire within the next 5 years.Conclusions: The demand for neurological services continues to outstrip resources despite the increased number of neurologists. Impending retirement of community neurologists will exacerbate manpower issues unless adequate numbers of trainees choose general neurologic practice in the community as a career.
