Abstract
INTRODUCTION Movement disorders emergencies describe acute-onset neurological conditions in which a delay of recognition and treatment may cause severe morbidity and mortality of patients. Hyperkinetic movement disorders include tremor, chorea/ballism, dystonia, myoclonus, and tics. Here we present a standard operating procedure (SOP) for the diagnostic work-up and different treatment options depending on the phenomenology as well as the aetiology of underlying diseases. COMMENTS The recognition of the phenomenology is essential for the symptomatic therapy of the acute movement disorder and forms the basis for the choice of ancillary investigations to confirm the suspected underlying causes. Furthermore, we summarise diagnostic techniques, including blood and cerebrospinal fluid tests and neuroimaging, which provide rapid results and are useful for the indication of causal treatments of specific acute movement disorders. CONCLUSIONS Despite their acute nature, most of these conditions can result in good clinical outcomes, if recognised early.

Abstract
BACKGROUND Functional Neurologic Disorders (FND) are a common but heterogeneous group of disabling conditions. The Emergency Department (ED) is an important venue for care and referral as it is often the first point of contact when patients with FND are faced with a crisis or exacerbation of symptoms. METHODS ED providers (n = 273) practicing in the Cleveland Clinic Foundation Northeast Ohio network were invited to participate through secure web application electronic surveys. Data were collected on practice profiles, knowledge, attitudes, management of FND, and awareness of available resources for FND. RESULTS Sixty providers completed the survey (22% response rate; n = 50 ED physicians, 10 advanced care providers) with 95.0% (n = 57) reporting a lack of understanding about FND. The terms Psychogenic Nonepileptic Seizures and stress induced/stress related disease were used by 60.0% (n = 36) and 58.3% (n = 35) respectively. Ninety percent (n = 53) rated their experience with managing FND patients as at least more difficult. Eighty- five percent (n = 51) agreed with "rule out others" and 60% (n = 36) agreed with "caused by psych stress". Eighty six percent (n = 50) believe that there is a difference between FND from malingering. Only one respondent was familiar with any FND resources and 79% (n = 47) reported the need for FND specific educational materials. CONCLUSION This survey revealed major gaps in knowledge, inaccurate perceptions, and management that differs from the current standard of care among ED providers caring for patients with FND. Educational opportunities are needed to guide diagnosis and evidence-based treatment to optimize management of patients with FND.

Abstract
Drug-induced movement disorders (DIMDs) are most commonly associated with typical and atypical antipsychotics. However, other drugs such as antidepressants, antihistamines, antiepileptics, antiarrhythmics, and gastrointestinal drugs can also cause abnormal involuntary movements. Different types of movement disorders can also occur because of adverse drug reactions. Therefore, the important key to diagnosing DIMDs is a causal relationship between potential offending drugs and the occurrence of abnormal movements. The pathophysiology of DIMDs is not clearly understood; however, many cases of DIMDs are thought to exert adverse mechanisms of action in the basal ganglia. The treatment of some DIMDs is quite challenging, and removing the offending drugs may not be possible in some conditions such as withdrawing antipsychotics in the patient with partially or uncontrollable neuropsychiatric conditions. Future research is needed to understand the mechanism of DIMDs and the development of drugs with better side-effect profiles. This article reviews the phenomenology, diagnostic criteria, pathophysiology, and management of DIMDs.

Abstract
PURPOSE OF REVIEW To analyze the interrelated factors that have led to the striking increase in functional movement disorders in recent years, with a focus on functional tic-like behaviours (FTLB). RECENT FINDINGS The sudden onset of FTLB has been widely observed in several countries since the beginning of the SARS-CoV-2 pandemic, whereas it was previously very rarely reported. Pandemic-related FTLB typically occur in young females, share complex, disabling and tic-lookalike patterns, and are usually triggered by the exposure to videos portraying tic-like behaviours on social media. Both pandemic-related FTLB and prepandemic FTLB are associated with high levels of depression and anxiety. FTLB related to the pandemic highlight the role of social media in the psychopathological behaviours of our time. SUMMARY We suggest FTLB are due to a combination of predisposing factors (high genetic and epigenetic risk for anxiety and depression, negative past experiences) and precipitating factors (pandemic and its impact on mental health, exposure to certain social media content). These factors of vulnerability may increase the risk of developing behavioural and emotional problems in youth, such as FTLB. Early diagnosis and appropriate treatment of psychiatric comorbidities seem to be predictors of positive prognosis.

Abstract
We provide a narrative review of functional neurological disorder (FND, or conversion disorder) for the emergency department (ED). Diagnosis of FND has shifted from a "rule-out" disorder to one now based on the recognition of positive clinical signs, allowing the ED physician to make a suspected or likely diagnosis of FND. PubMed, Google Scholar, academic books, and a hand search through review article references were used to conduct a literature review. We review clinical features and diagnostic pitfalls for the most common functional neurologic presentations to the ED, including functional limb weakness, functional (nonepileptic) seizures, and functional movement disorders. We provide practical advice for discussing FND as a possible diagnosis and suggestions for initial steps in workup and management plans.

Abstract
OBJECTIVES Diagnosis of hyperkinetic movement disorders with an unknown cause is usually challenging. The objective of this study is to learn about video electroencephalogram (VEEG) combined with electromyography (EMG) in the diagnosis of hyperkinetic movement disorders with an unknown cause. METHODS We performed an observational cohort study by recruiting consecutive patients with hyperkinetic movements as the main manifestation with an unknown cause for VEEG combined with EMG evaluations. RESULTS A total of 77 consecutive patients were enrolled for VEEG-EMG examination. Among them, 57 patients changed their diagnosis after VEEG-EMG assessment, with a mean final diagnosis age of 35.4 ± 20.3 years (range, 4-74 years). The mean duration between initial and final diagnosis was 54.8 ± 71.3 months (range 0.5-300 months). The most common misdiagnosed hyperkinetic movement disorders were myoclonus (40.4%), followed by tremors (24.6%), dystonia (15.8%), psychogenic movement disorders (10.5%), and periodic leg movement syndrome (PLMS) (7.0%). Outcomes of therapy were significantly improved after VEEG-EMG examination (p = 0.000). CONCLUSIONS Simultaneous VEEG and EMG are important in the diagnosis of hyperkinetic movement disorders with an unknown cause.

Abstract
Movement disorders are typically perceived as being gradually progressive conditions that are managed in outpatient settings. However, they may manifest de novo with an acute severe phenotype or an acute decompensation. A movement disorder becomes an emergency when it evolves acutely or subacutely over hours to days; delays in its diagnosis and treatment may cause significant morbidity and mortality. Here we address the clinical presentation, diagnosis and management of those movement disorder emergencies that are principally encountered in emergency departments, in acute receiving units or in intensive care units. We provide practical guidance for management in the acute setting where there are several treatable causes not to be missed. The suggested medication doses are predominantly based on expert opinion due to limited higher-level evidence. In spite of the rarity of movement disorder emergencies, neurologists need to be familiar with the phenomenology, potential causes and treatments of these conditions. Movement disorder emergencies divide broadly into two groups: hypokinetic and hyperkinetic, categorised according to their phenomenology. Most acute presentations are hyperkinetic and some are mixed.

Abstract
BACKGROUND Functional gait disorders (FGDs) are relatively common in patients presenting for evaluation of a functional movement disorder (FMD). The diagnosis and classification of FGDs is complex because patients may have a primary FGD or a FMD interfering with gait. METHODS We performed a detailed evaluation of clinical information and video recordings of gait in patients diagnosed with FMDs. RESULTS We studied a total of 153 patients with FMDs, 68% females, with a mean age at onset of 36.4 years. A primary FGD was observed in 39.2% of patients; among these patients, 13 (8.5%) had an isolated FGD (a gait disorder without other FMDs). FMDs presented in 34% of patients with otherwise normal gait. Tremor was the most common FMD appearing during gait, but dystonia was the most common FMD interfering with gait. Patients with FGD had a higher frequency of slow-hesitant gait, astasia-abasia, bouncing, wide-based gait and scissoring compared with patients with FMDs occurring during gait. Bouncing gait with knee buckling was more frequently observed in patients with isolated FGD (P = 0.017). Patients with FGDs had a trend for higher frequency of wheelchair dependency (P = 0.073) than those with FMDs interfering with gait. CONCLUSIONS Abnormal gait may be observed as a primary FGD or in patients with other FMDs appearing during gait; both conditions are common and may cause disability.
