Однак неврологічні особливості інфекції COVID-19, особливо в молодих, раніше здорових людей, майже не наведені в літературі. Мета дослідження: надати короткий огляд неврологічних і нейропсихічних проявів та ускладнень COVID-19, підкріплений описом клінічного випадку. Матеріали та методи. Було проведено всебічний електронний пошук літератури з використанням баз даних Scopus, PubMed, Embase, Cochrane, Всесвітньої організації охорони здоров’я, Ovid та Google Scholar відповідно до бажаних елементів звітності для систематичних оглядів і керівних принципів метааналізу, щоб визначити статті, у яких обговорювалися неврологічні та ней-ропсихічні прояви SARS-CoV-2/COVID-19. Неврологічні прояви та ускладнення COVID-19 ілюструються клінічним випадком у раніше здорової молодої людини білої раси. Результати та висновки. Неврологічні та нейропсихічні прояви та ускладнення інфекції SARS-CoV-2 варіюють від легких симптомів, таких як головний біль, до катастрофічних, включаючи делірій, маніакальні епізоди, шизофренію, інсульт, гостру геморагічну некротизуючу енцефалопатію, поперечний мієліт, енцефаліт, менінгіт, синдром Гієна — Барре. Ми навели огляд неврологічних та нейропсихічних проявів та ускладнень інфекції SARS-CoV-2, проілюстрований клінічним випадком.

Background. As the second wave of COVID-19 occurred, it has become clear that a novel coronavirus (SARS-CoV-2), which has consequently sparked a global pandemic, was evolved into wide-ranging multi-organ disease. However, neurological features of COVID-19 infection, especially in young previously healthy adults, have not been widely reported. We aimed to provide a narrative review of the neurological and neuropsychiatric manifestations and complications of SARS-CoV-2, supported with a clinical case presentation. Materials and methods. A comprehensive electronic literature search was performed on Scopus, PubMed, Embase, Cochrane database, World Health Organization database, Ovid, and Google Scholar in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines to identify the articles that discussed the neurological and neuropsychiatric presentations of SARS-CoV-2/COVID-19. The neurological manifestations and complications of COVID-19 are illustrated with the clinical case presentation in a previously healthy white young adult. Results and conclusions. Neurological and neuropsychiatric manifestations and complications of SARS-CoV-2 infection range from mild symptoms, such as headache, to catastrophic symptoms, including but not limited to delirium, manic episodes, schizophrenia, stroke, acute hemorrhagic necrotizing encephalopathy, transverse myelitis, encephalitis, meningitis, and Guillain-Barré syndrome. We provided a narrative review of the neurological and neuropsychiatric manifestations and complications of SARS-CoV-2 infection, illustrated with the clinical case presentation in a previously healthy white young adult.

Introduction
The morbidity and mortality of the global community due to the outbreak of novel coronavirus disease 2019 (COVID-19), caused by a highly transmittable viral infection, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is increasing dramatically. On March 11, 2020, the World Health Organization characterized COVID-19 as a pandemic, pointing to over 3 million cases and 207,973 deaths in 213 countries and territories [1]. As of January 6, 2021, the COVID-19 pandemic has resulted in more than 87.6 million confirmed cases worldwide and over 1.9 million deaths [2]. It is the largest and most severe pandemic since the 1918 influenza pandemic [3].
The COVID-19 pandemic has not only become the greatest public health crisis of 2020 but has also caused the largest global recession in history, with more than a third of the global population at the time being placed on lockdown [4]. Lockdown froze the economies with unprecedented force and speed. Worldwide, 660 million workers lost their jobs, 38 million have filed for unemployment insurance during the pandemic. A record 3.28 million Americans applied for unemployment benefits, the highest number ever recorded [5].
The primary manifestations of COVID-19 are respiratory. However, it has become clear that SARS-CoV-2 can affect multiple parts of the body, including the nervous system. Despite that, neurological features of COVID-19 infection, especially in young previously healthy patients, have not been widely reported and fully investigated.
The purpose of the study: to provide a comprehensive narrative review of the neurological and neuropsychiatric manifestations and complications of SARS-CoV-2 infection, illustrated with the clinical case presentation of neurological features of COVID-19 infection in a previously healthy young white adult.
Materials and methods
A comprehensive electronic literature search was accomplished on Scopus, PubMed, Embase, Cochrane database, World Health Organization database, Ovid, and Google Scholar in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines to identify the articles that discussed the neurological and neuropsychiatric presentations, manifestations, and complications of SARS-CoV-2/COVID-19. The applicable articles are cited and referenced. No limit placed on publication time or the language of the article.
Studies were included if they have reported specific outcomes on any aspects of neurological symptoms in relation to COVID-19; the main exclusion criteria were commentary, editorials, narrative reviews with no reports on case outcomes or treatment method. Articles, reported non-specific neurological symptoms in COVID-19 patients, such as dizziness, headache, fatigue, and myalgia, which are all likely to be caused by the systemic condition, as well as those that were reporting worsening neurological symptoms, such as impaired consciousness that could be fully accounted for by sedation during ventilation, were also excluded. All the re-levant articles were identified and screened by two authors (O. Fartushna and H. Palahuta), and disagreements were resolved by consensus and involvement of senior author (S. Yevtushenko); the results are summarized narratively.
We provided a complex clinical, neurological, laboratory, and instrumental analysis of manifestations and complications of SARS-CoV-2 infection in a previously healthy young white adult, admitted to the Regional Clinical Center of Neurosurgery and Neurology, the city of Uzhhorod, Ukraine.
Results and discussion
The clinical spectrum of the SARS-CoV-2 infection appears to be wide, including asymptomatic infection, mild upper respiratory tract illness, and severe viral pneumonia with respiratory failure, and death [6, 7]. Furthermore, various complications beyond the respiratory system, such as acute myocardial injury, acute kidney injury, gastrointestinal, liver, heart, skin injuries, neurological, and neuropsychiatric presentations have been reported [8–16]. The involvement of the nervous system in COVID-19 patients may be related to poor prognosis and disease worsening.
We analyzed, systemized, and summarized all relevant specific neurological and neuropsychiatric presentations, manifestations, and complications of SARS-CoV-2 infection that are reported in medical articles as of January 7, 2021 (Table 1).

The neurological and neuropsychiatric manifestations, presentations, and complications of SARS-CoV-2 infection include a wide range of symptoms and diseases from mild to severe. Articles, reported non-specific neurological symptoms in COVID-19 patients, such as dizziness, headache, fatigue, and myalgia, which are all likely to be caused by the systemic condition, as well as those reported worsening neurological symptoms, such as impaired consciousness that could be fully accounted for by sedation during ventilation, were excluded and are not analyzed in this article.
Neurological presentations of SARS-CoV-2
In COVID-19, both central and peripheral nervous systems can be affected. Reports are emerging of neurological presentations of SARS-CoV-2, which range from mild symptoms, such as headache, to catastrophic symptoms, including but not limited to stroke, acute hemorrhagic necrotizing encephalopathy, delirium, transverse myelitis, ence-phalitis/meningitis, and Guillain-Barré syndrome [17–20]. Moreover, in some cases, the neurological manifestations can precede typical respiratory presentation like fever and cough. It was suggested that SARS-CoV-2 can cause neural damage because of direct viral invasion, through hypoxic and immune-mediated pathways, and cytokine storm [3, 6].
Central nervous system presentations of SARS-CoV-2
The central nervous system manifestations and complications of COVID-19 include, but are not limited to headache, dizziness, epilepsy, ataxia, meningitis, encephalitis, acute hemorrhagic necrotizing encephalopathy, acute demyelinating encephalomyelitis, impaired consciousness, and stroke [19–21].
In some studies, encephalopathy is reported in 40 % of COVID-19 patients [18]. The acute cerebrovascular di-seases are also emerging as an important manifestation of COVID-19, with cohort studies reporting stroke in 2–6 % of patients hospitalized with COVID-19 [3]. Several reports of acute myelitis associated with COVID-19 infection have been published in the literature, in which COVID-19 is associated with the onset of acute myelitis as a neurological complication [22–27].
Peripheral nervous system and muscle disease presentations of SARS-CoV-2
Reported peripheral nervous system manifestations and complications of COVID-19 include skeletal damage, anosmia, chemosensory dysfunction, and Guillain-Barré syndrome.
In a recent multi-center European study of 417 COVID-19 patients, 85.6 % of patients were diagnosed with olfactory dysfunction and 88.8 % of patients reported gustatory disorders. Around 72.6 % of patients recovered their olfactory functions within the first 8 days [28]. It is believed that anosmia and dysgeusia occurred since the SARS-CoV-2 virus can directly enter the nervous system via the olfactory tract or bloodstream at a pro-inflammatory stage of the di-sease [6, 18, 29].
Few cases of COVID-19 associated with Guillain-Barré syndrome, as well as polyneuropathy and Miller Fisher syndrome have been reported [30, 31]. Muscle injury and rhabdomyolysis due to COVID-19 have also been reported [32].
Neuropsychiatric presentations of SARS-CoV-2
Patients with SARS-CoV-2 show higher manifestations of depression, anxiety, and post-traumatic stress disorder symptoms when compared with non-COVID controls [33]. Delirium, encephalopathy, and acute behavioral changes are common neuropsychiatric signs of COVID-19. Recently, a case report showed that manic-like symptoms might be a delayed response to SARS-CoV-2 in patients with no history of psychiatric illness [34].
Neuropsychiatric presentations of COVID-19 are directly related to an increase in peripheral immunological markers, the severity of infection, and the case fatality rate. Unmitigated neuroinflammation has been noted to underlie not only the severe respiratory complications of the disease but is also present in a range of neuropsychiatric illnesses [35, 36].
Health care providers should be aware that, apart from respiratory symptoms, neurological and psychiatric symptoms can manifest in patients with COVID-19. It has been also suggested that the long-term effect of the neuroinvasive nature of COVID-19 may increase the risk of neurodege-nerative disease, like multiple sclerosis, chronic encephalopathies, neuromuscular disorders, neuropathies, demyelinating and degenerative conditions occurring a long time after the initial presentation, as it was reported to be after the SARS and MERS outbreaks [37, 38].
Clinical case presentation
Neurological manifestations of SARS-CoV-2
A previously healthy young white man presented to his primary care physician complaining of fatigue, mild headache, moderate low back pain, sub-febrile temperature, loss of taste (dysgeusia) and smell (anosmia) for the past few days. He stated that symptoms occurred gradually. The patient is a student in his middle twenties. He stated that he is living with his family and was in close contact with his family and friends. Suspecting COVID-19, the primary care physician performed an X-ray of the chest that showed no pathology. The patient was recommended to self-quarantine for 14 days, rest and stay hydrated, monitor the symptoms carefully, and if symptoms get worse, call the health care
provider immediately. The symptoms disappeared spontaneously in 14 days.
Neurological complications of SARS-CoV-2
On the 20th day from the time of loss of smell and taste, the patient developed weakness in his legs and began to experience difficulty urinating. Over the next 7 days, sub-febrile condition and pain in the lumbar and thoracic spine were noted. This was accompanied by progressive weakness of the lower extremities, difficulty walking, and constipation. The patient applied to the emergency department of the Regional Clinical Center of Neurosurgery and Neurology, Uzhhorod, Ukraine.
On physical examination, he is a muscular, thickset normosthenic individual with a healthy appearance and no fever. His heart rate was 65/min, respiratory rate was 16/min, and blood pressure was 120/75 mm Hg in both arms. Lung auscultation reveals no pathology. Cardiac auscultation detects no rubs or murmurs. He was not taking any medications prior to admission. Clinical neurological examination revealed decreased muscle strength and tone, hyporeflexia, decreased proprioception of the lower extremities, and pa-resthesia on both sides from the Th9 level. No pathological reflexes were found. The patient was hospitalized for further examination and treatment.
His general blood tests as well as renal and liver function laboratory results were normal. MRI of the spine showed a segment of increased T2 signal in the center of the spinal cord at the Th11–Th12 level. MRI of the brain and orbits revealed no abnormalities. Cerebrospinal fluid showed increased protein levels and lymphocytic pleocytosis. A serologic blood test for SARS-CoV-2 showed recent infection (presence of SARS-CoV-2/IgG as determined by internal immunofluorescence antibody testing). Antibodies to anti-myelin-associated glycoprotein IgM and IgG to optic neuromyelitis were negative in serum.
Corticosteroid treatment led to full recovery within a week of hospitalization. The patient was discharged home. One-month follow-up revealed no symptoms of recurrence or any pathology.
Conclusions
Notwithstanding, the COVID-19 primarily affects the respiratory and cardiovascular systems, neurological involvements are not uncommon and can result in serious complications if not detected and managed early. Neurological presentations of SARS-CoV-2 infection in some cases precede the respiratory symptoms or may be the only symptoms in COVID-19 patients. Neurological and neuropsychiatric manifestations and complications of SARS-CoV-2 infection range from mild symptoms, such as headache, to catastrophic symptoms, including stroke, acute hemorrhagic necrotizing encephalopathy, encephalopathy, delirium, severe agitation, manic episodes, schizophrenia, transverse myelitis, encephalitis/meningitis, and Guillain-Barré syndrome.
We present a narrative review of the neurological manifestations and complications of COVID-19, accompanied by a clinical case report, to raise awareness about possible neurological diseases, resulting from this novel SARS-CoV-2 infection.
