ABSTRACT

BACKGROUND: Albeit primarily a disease of respiratory tract, the 2019 coronavirus infectious disease (COVID-19) has been found to have causal association with a plethora of neurological, neuropsychiatric and psychological effects. This review aims to analyze them with a discussion of evolving therapeutic recommendations. METHODS: PubMed and Google Scholar were searched from 1 January 2020 to 30 May 2020 with the following key terms: "COVID-19", "SARS-CoV-2", "pandemic", "neuro-COVID", "stroke-COVID", "epilepsy-COVID", "COVID-encephalopathy", "SARS-CoV-2-encephalitis", "SARS-CoV-2-rhabdomyolysis", "COVID-demyelinating disease", "neurological manifestations", "psychosocial manifestations", "treatment recommendations", "COVID-19 and therapeutic changes", "psychiatry", "marginalised", "telemedicine", "mental health", "quarantine", "infodemic" and "social media". A few newspaper reports related to COVID-19 and psychosocial impacts have also been added as per context. RESULTS: Neurological and neuropsychiatric manifestations of COVID-19 are abundant. Clinical features of both central and peripheral nervous system involvement are evident. These have been categorically analyzed briefly with literature support. Most of the psychological effects are secondary to pandemic-associated regulatory, socioeconomic and psychosocial changes. CONCLUSION: Neurological and neuropsychiatric manifestations of this disease are only beginning to unravel. This demands a wide index of suspicion for prompt diagnosis of SARS-CoV-2 to prevent further complications and mortality.


Les impacts neurologiques et neuropsychiatriques d'une infection à la COVID-19. CONTEXTE: Bien qu'il s'agisse principalement d'une maladie des voies respiratoires, la maladie infectieuse à coronavirus apparue en 2019 (COVID-19) s'est avérée avoir un lien de causalité avec une pléthore d'impacts d'ordre neurologique, neuropsychiatrique et psychologique. Cette étude entend donc analyser ces impacts tout en discutant l'évolution des recommandations thérapeutiques se rapportant à cette maladie. MÉTHODES: Les bases de données PubMed et Google Scholar ont été interrogées entre les 1er janvier et 30 mai 2020. Les termes clés suivants ont été utilisés : « COVID-19 ¼, « SRAS ­ CoV-2 ¼, « Pandémie ¼, « Neuro ­ COVID ¼, « AVC ­ COVID ¼, « Épilepsie ­ COVID ¼, « COVID ­ encéphalopathie ¼, « SRAS ­ CoV-2 ­ encéphalite ¼, « SRAS ­ CoV-2 ­ rhabdomyolyse ¼, « COVID ­ maladie démyélinisante ¼, « Manifestations neurologiques ¼, « Manifestations psychosociales ¼, « Recommandations thérapeutiques ¼, « COVID-19 et changement thérapeutiques ¼, « Psychiatrie ¼, « Marginalisés ¼, « Télémédecine ¼, « Santé mentale ¼, « Quarantaine ¼, « Infodémique ¼ et « Médias sociaux ¼. De plus, quelques articles de journaux relatifs à la pandémie de COVID-19 et à ses impacts psychosociaux ont également été ajoutés en fonction du contexte. RÉSULTATS: Il appert que les manifestations neurologiques et neuropsychiatriques des infections à la COVID-19 sont nombreuses. Les caractéristiques cliniques d'une implication des systèmes nerveux central et périphérique sautent désormais aux yeux. Ces caractéristiques ont fait l'objet d'une brève analyse systématique à l'aide de publications scientifiques. En outre, la plupart des impacts d'ordre psychologique de cette pandémie se sont révélés moins apparents que les changements réglementaires, socioéconomiques et psychosociaux. CONCLUSION: Les manifestations neurologiques et neuropsychiatriques de cette maladie ne font que commencer à être élucidées. Cela exige donc une capacité accrue de vigilance en vue d'un diagnostic rapide, et ce, afin de prévenir des complications additionnelles et une mortalité accrue.

ABSTRACT

The varicella zoster virus (VZV) is a ubiquitous, neurotropic pathogen capable of reactivation from sensory ganglion cells to cause dermatomal herpes zoster infection, alongside a range of pathologies within the central nervous system. The presence of VZV cerebellitis without skin manifestations, however, is exceedingly rare in immunocompetent adults.We report a case of VZV cerebellitis in an immunocompetent woman in her 70s, in the absence of a rash. The patient presented with a 2-week history of progressive gait ataxia, headache and mild confusion. Serological tests and neuroimaging were unremarkable. Diagnosis was confirmed through cerebrospinal fluid (CSF) analysis which revealed lymphocytosis and the presence of VZV DNA on PCR analysis. The patient showed symptomatic improvement following empirical acyclovir treatment, corroborated by favourable CSF analysis 10 days post-treatment initiation.Infective aetiology, including VZV, should be considered in patients presenting with acute cerebellar ataxia, even in immunocompetent adults with an absence of dermatological signs.

ABSTRACT

Cerebellar ataxia can be caused by neoplasia, toxics (drugs, heavy metals, alcohol), infection, vascular lesions or auto-immune and paraneoplastic pathologies. Neuroimaging must be performed urgently in case of sudden onset and serologies as well as a lumbar puncture should be performed. Several case reports of ataxia associated with COVID-19 have been published, however the underlying pathogenic mechanisms remain unclear. This is a diagnosis of exclusion when other causes are ruled out and when the ataxia appears simultaneously to COVID-19 infection. We lack data on best management, but the prognosis appears mostly favorable with good functional recovery without any specific treatment. This paper describes the case of a patient who developed a cerebellar ataxia as the only neurological manifestation of a SARS-CoV-2 infection.


Une ataxie cérébelleuse peut être causée par un processus (para)néoplasique, auto-imun, une exposition toxique, une infection ou une lésion vasculaire. Une imagerie doit être réalisée en urgence devant toute atteinte aiguë et le bilan devrait être complété par des sérologies larges et une ponction lombaire. Plusieurs cas d'ataxie liée au Covid-19 ont été décrits, dont le mécanisme étiopathogénique reste incomplètement élucidé, le diagnostic se faisant plutôt par exclusion lorsque les symptômes apparaissent de manière concomitante à l'infection. Des données manquent sur la prise en charge mais le pronostic semble favorable, avec une bonne récupération fonctionnelle. Cet article décrit le cas d'une patiente ayant présenté une ataxie cérébelleuse comme symptôme neurologique isolé contemporain d'une infection à SARS-CoV-2.

ABSTRACT

BACKGROUND: The outbreak of coronavirus disease 2019 (COVID-19) has been widely reported to cause symptoms such as fever, cough, sore throat, fatigue, and shortness of breath. Neurologic complications have not been widely reported without associated respiratory symptoms. These neurologic manifestations have been found mostly in the elderly. There has been no report of ataxia or COVID-19 cerebellitis in the young adult population without associated respiratory symptoms. CASE REPORT: Here we report the case of a 30-year-old patient who presented with isolated cerebellar symptoms and was diagnosed with COVID-19 cerebellitis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is important for emergency physicians to know that COVID-19 can have many clinical manifestations and to have a high level of suspicion with acute neurologic symptoms.
