ABSTRACT
Introduction: Catatonia is a syndrome of primarily psychomotor disturbances most common in psychiatric mood disorders but that also rarely has been described in association with cannabis use. Case Presentation: A 15-year-old White male presented with left leg weakness, altered mental status, and chest pain, which then progressed to global weakness, minimal speech, and a fixed gaze. After ruling out organic causes of his symptoms, cannabis-induced catatonia was suspected, and the patient responded immediately and completely to lorazepam administration. Discussion(s): Cannabis-induced catatonia has been described in several case reports worldwide, with a wide range and duration of symptoms reported. There is little known about the risk factors, treatment, and prognosis of cannabis-induced catatonia. Conclusion(s): This report emphasizes the importance of clinicians maintaining a high index of suspicion to accurately diagnose and treat cannabis-induced neuropsychiatric conditions, which is especially important as the use of high-potency cannabis products in young people increases.Copyright © 2023, State Medical Society of Wisconsin.

ABSTRACT
Background: Large-scale vaccination against the novel coronavirus (COVID-19) occurred globally at an unprecedented pace. Sporadic cases of autoimmune encephalitis (AE) have been reported following COVID-19 vaccination, mainly in adults. Case report: A 14-year-old girl developed altered mental status and was brought to our emergency department because of a seizure 19 days after receiving the third dose of COVID-19 vaccination. She was treated with steroid pulse therapy and fully recovered. The diagnosis of probable autoantibody-negative AE was finally made. Conclusion(s): This case met the criteria for probable autoantibody-negative AE in children, as well as adults. Because of the temporal association and absence of another identifiable cause, her conditions may have been triggered by the COVID-19 vaccination. To our knowledge, this is the first published pediatric case of autoantibody-negative but probable AE following COVID-19 vaccination.Copyright © 2023 The Authors
ABSTRACT
Background: During the era of the Coronavirus disease 2019 (COVID-19) pandemic, various neurological syndromes were reported during or after the infection. Fortunately, efforts were made to successfully develop various vaccines with high efficacy and safety. Despite the promising results of those vaccines, they are too novel to be fully understood. Here we are shedding light on a neurological case presentation that may be attributed to one of the COVID-19 vaccines. Case presentation: A 23-year-old male patient with no prior comorbidities presented with quadriparesis and numbness that were clinically and electrophysiologically consistent with Guillain-Barre Syndrome (GBS). The condition started 10 days after the first dose of the AstraZeneca vaccine. Moreover, MRI of the brain and spinal cord has shown evidence of non-specific central demyelination. Despite the radiological finding, the patient is not fulfilling the diagnosis of a known demyelination disorder and the lesions regressed on follow-up. Since no better explanation or trigger could be found, a post-vaccination immune-mediated reaction was considered. Conclusion(s): We still cannot assume the certainty of the causality association between the vaccine and the neurological presentation. Meanwhile, we suggest vigilance for cases of GBS or myelitis following vaccination for Covid-19 and that post-vaccination surveillance programs ensure a statistically significant tool to prove or dispsrove the causality.Copyright © 2022 The Authors
ABSTRACT
Since the introduction of COVID-19 vaccine, various adverse events have been reported including injection site pain, fatigue, headaches, and myocarditis. Cranial neuropathies and optic neuritis, have been also rarely reported, however, the significance of these autoimmune manifestations after the administration of COVID-19 vaccine remain controversial. In this report we present a case of myocarditis and bilateral optic neuritis that occurred in a young healthy male patient after the administration of first dose of mRNA-1273 vaccine (Moderna).Copyright © 2022 The Author(s)
ABSTRACT
Background: Literature describing triggers of GFAP astrocytopathy (GFAP-A) is limited. We report a case of GFAP-A in a patient with recent messenger ribonucleic acid (mRNA) severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) vaccination and discuss the possible pathogenesis. Case description: A 45-year-old gentleman presented with features of meningoencephalitis 31 days after the first dose and 4 days after the second dose of mRNA SARS-CoV-2 vaccination. He sequentially developed brainstem/cerebellar, autonomic and cord dysfunction. Cerebrospinal fluid was positive for GFAP autoantibody. Clinical improvement occurred after intravenous methylprednisolone and immunoglobulins. Conclusion(s): Although we are uncertain of a causal link of GFAP-A to mRNA vaccine, indirect activation of an underlying dysregulated immune milieu is plausible.Copyright © 2021 The Author(s)
ABSTRACT
Background: There has been lot of speculation around the possible side effects associated with COVID vaccination and incidence of facial palsy is one of them. Bilateral facial palsy is less likely to be idiopathic as compared to unilateral facial nerve palsy and warrants further investigations to find any secondary cause. COVID 19 infection and the vaccinations for the same are also included in the unique list of differentials. Case report: We report an interesting case of bilateral rapidly sequential facial nerve palsy following the administration of COVID vaccination that showed subsequent improvement. We provide literature review to report the current incidence of same, secondary to the vaccination as well the infection itself Case presentation: Following the introduction of COVID 19 vaccine, there have been reports of various cranial nerve involvement including lower motor neuron type facial paresis. Bilateral facial palsy is less likely to be idiopathic as compared to unilateral palsy(23% vs 70%) and requires further work up to determine the etiology before determining to be idiopathic. Unilateral facial palsy(FP) has been reported in the Phase I and II trials for Pfizer and Moderna vaccine, with a total of 7 cases reported in these initial trials. To date, there is no direct evidence that these vaccines have increased the incidence of facial palsy as compared to adverse events reported with other vaccines or compared to COVID 19 infection itself. We report a unique case of bilateral lower motor neuron type facial palsy noted in a young male within hours of receiving the vaccine that later improved with treatment. Reports of simultaneous bilateral facial palsy after vaccine are rare with only few cases reported to date in literature. Conclusion(s): In conclusion from current available literature, we would like to postulate that though there is a risk of facial nerve palsy following the vaccination, it is comparable to the risks associated with any other vaccinations and not been higher than the non-vaccinated population. The overall risk is higher with the actual COVID 19 infection itself as compared to the vaccine.Copyright © 2022
ABSTRACT
A 20-year-old patient was presented with subacute onset of headache, nausea and vomiting. Testing of nasal/oropharyngeal swabs indicated the presence of SARS-CoV-2 RNA, and later the antibodies to this virus were found. The treatment in the hospital for Coronavirus 19 Disease (COVID-19) provided only temporary relief, and the patient then was referred to the Regional Stroke Center (RSC) to exclude a subarachnoid hemorrhage. RSC neurologists drew attention to multiple skin nevi in the patient. Brain MRI demonstrated abnormal T1 hyperintensity in the brain leptomeninges, with leptomeningeal contrast enhancement as well as hyperintensity in amygdala regions on T1 weighted images, bilaterally. The anomaly of the Dandy-Walker malformation complex was also revealed. Cerebrospinal fluid (CSF) analysis showed elevated protein (0.52 g/L), low lymphocytosis (lymphocytes, 6 in mm3), and decreased glucose (1.8 mmol/L). Neurocutaneous melanocytosis (NCM) was diagnosed, which neurological manifestation was probably triggered by COVID-19. The patient's vision gradually progressively worsened. In 2.5 months after the clinical manifestation of NCM, fundoscopy revealed optic discs atrophy (despite the absence of previous edema), and repeated CSF analysis showed atypical cells with characteristics corresponding to melanoma. Malignant transformation of cerebral melanocytosis was suspected, and the patient was referred to an oncological dispensary for further therapy. In the presented literature review, special attention is paid to the issues of neuroimaging, cytological and immunocytochemical diagnostics of NCM.Copyright © Russian Neurological Journal.

ABSTRACT
Background: Cerebral amyloid angiopathy related inflammation (CAA-RI) is a neuroinflammatory disease that is associated with perivascular amyloid- deposition. Case presentation: A middle-aged woman with a remote history of autoimmune disorders presented with unilateral migraine headaches, dizziness, unsteadiness, and fogginess 36 hours after administration of mRNA vaccine against SARS-CoV-2. Initially, unilateral leptomeningeal enhancement on MRI on the same side of headaches raised suspicion for leptomeningeal involvement of her known cutaneous T-cell lymphoma in remission. After two relatively unremarkable CSF analyses, she underwent a brain biopsy which showed amyloid deposits in vessels instead of lymphomatous infiltration. She was diagnosed with CAA-RI, and the headache and cognitive symptoms responded well to high-dose corticosteroids with a slow taper. Discussion/conclusion: We review the clinical literature of CAA-RI and its potential association with amyloid-related imaging abnormalities (ARIA) after administration of immunotherapy against amyloid.Copyright © 2022
ABSTRACT
Background: Cases of SARS-COV-2 triggering or exacerbating autoimmune responses has been described in the literature, and it has shown that use of steroids in non-severe COVID-19 may potentially increase mortality. Case presentation: A 22 year-old African-American man presented with headache, weight, loss, and oral/scrotal ulcerations. Case report: Neurological exam revealed somnolence and right hemiplegia. MRI was remarkable multiple enhancing lesions involving the brainstem and left hemisphere. He was found to have a positive SARS-CoV-2 test. Work-up was unrevealing, and he was diagnosed with Neuro-Behcet's disease (NBD) based on the International Criteria for Behcet's Disease (ICBD)ackspaceD)BackspaceBackspacep. The patient was treated with systemic steroids, which resulted in both clinical and radiological improvement of his disease without exacerbation of his SAR-CoV-2 infection. Conclusion(s): This case presentation suggests that IV steroids may be safe in the treatment of NBD in adult patients presenting with SARS-CoV-2 infection.Copyright © 2021
ABSTRACT
Case Report: Acute motor and sensory axonal neuropathy (AMSAN) syndrome is a rare subtype of Guillain-Barre syndrome (GBS) with poor recovery [1]. While respiratory and gastrointestinal infections may precipitate AMSAN, an underlying autoimmune disorder is seldom reported in literature. We herein report the complex case of a patient with undiagnosed, asymptomatic mixed connective tissue disease (MCTD) who developed AMSAN syndrome. Case: A 44-year-old Asian male without medical history presented with progressively worsening weakness of both upper and lower extremities and inability to perform daily activities. His symptoms started 12 weeks prior with difficulty standing from a seated position. He felt subjectively better for some time until a week prior, when he became bedbound. He had diarrhea 6 months ago, with 5-6 loose bowel movements a day for a few weeks. Vital signs on admission was normal. On neurological examination, he was alert and oriented, with bilateral upper and lower extremity flaccid paralysis, diffuse muscle atrophy, bilateral hand and foot drop, negative Hoover sign, diffuse areflexia, and intact sensation. Cerebrospinal fluid (CSF) analysis showed WBC 0 and protein level 136. MRI cervical, thoracic, and lumbar spine were normal. EMG revealed sensory involvement with positive sharp waves in proximal muscles along with fibrillations. Intravenous immunoglobulin (IVIG) was initiated at 0.4 mg/kg for 5 days. Infectious workup for COVID-19, stool culture, HIV, TB, RPR and campylobacter jejuni antibody (Ab), was negative. ANA was positive in a speckled pattern with titres 1:1280, with a positive RNP Ab, SS-A, and RF IgM, IgG and IgA. Rest of the autoimmune workup (anti-dsDNA, anti-CCP, SS-B, aldolase, anti-Jo-1, anti-Scl-70, p-ANCA, c-ANCA, anti-GM1, anti-GQ1b, and anti-GD1a ganglioside Ab) was negative. The myositis specific 11 Ab panel was negative. Despite IVIG therapy, he developed dysphagia, respiratory distress, with a negative inspiratory force of -0, requiring intubation. He had a tracheostomy and PEG tube placed and remains quadraplegic nearly 120 days later. Discussion(s): The authors report a unique case of a patient who became progressively weak over 3 months, leading to complete quadriplegia. Interestingly, this is more consistent with chronic inflammatory demyelinating poly-neuropathy (CIDP), as AMSAN typically develops over a short period of 2 to 4 weeks [2]. Despite having negative anti-GM1 and anti-GD1a Ab (in which positive Ab are pathognomonic but not always present in AMSAN syndrome), the patient had weakness that began in the lower extremities, progressing to paralysis, along with albuminocytological dissociation on CSF analysis, pointing to a GBS diagnosis [3]. He had sensory involvement in the EMG, thus making the diagnosis as AMSAN. He had an undiagnosed, asymptomatic autoimmune process most consistent with MCTD. Whether the two disease processes are related to each other is a concept that has not yet been investigated.

ABSTRACT
Objective Acquired neuromyotonia or Isaacs' syndrome is an immune mediated inflammatory disorder characterized by involuntary continuous muscle fiber activity manifesting as twitching and stiffness along with autonomic dysfunctions like hyperhidrosis and/or tachycardia. Here we report a young male who developed acquired neuromyotonia following COVID- 19 vaccination. Background A 20-year-old male presented in our clinic with gradually progressive pain and numbness in bilateral lower limbs, tremors in both hands, shivering while walking, excessive sweating and difficulty in micturition for last 15 days. He also noticed twitching of muscles in calf and thigh muscles along with these symptoms. According to patient, these symptoms started after he took his first dose of COVID-19 vaccination (Covishield- Oxford- AstraZeneca viral vector vaccine) 10 days back. There was no history of fever or backache. He had no chronic illness and was not on any medications. Examination revealed hyperhidrosis, mild proximal muscle weakness in both lower limbs with twitching in muscles suggestive of myokymia. There were quivering and rippling movements of intrinsic muscles of both hands resembling polyminimyoclonus. In view of the above findings, possibility of acquired neuromyotonia possibly following COVID-19 vaccination was kept and further evaluation was done. Design/Methods Routine blood investigations, thyroid function test, anti-thyroid peroxidase antibodies and anti-nuclear antibodies were normal. Cerebrospinal fluid analysis was normal. Anti-VGKC antibodies were detected in serum with strongly positive anti-CASPR and weakly positive anti-LGI1 antibodies confirming diagnosis of acquired neuromyotonia. Results Pulse dose of intravenous methylprednisolone for 5 days was given which resulted in visible improvement in pain, twitching, hyperhidrosis and urinary symptoms. He was continued on oral steroids and complete resolution of his symptoms was noted over a period of 2 months. Conclusions COVID-19 vector vaccine associated acquired neuromyotonia is a rare condition, but its early recognition and treatment is the key for a favorable prognosis.
ABSTRACT
Objective To report a case of Anti-Contactin-Associated Protein-like2 (CASPR-2) autoimmunity in a patient with low-grade Chronic Lymphocytic Leukemia (CLL) following COVID-19 vaccination and infection. Background Anti-CASPR2 antibody disorder has been associated with neoplastic disorders like thymoma. Recent reports enlist COVID-19 as apotential trigger of CASPR2 autoimmunity. While the clinical presentations are similar, management differs based on the underlying etiology. Design/Methods We review a case of anti-CASPR2-antibody associated disorder with concurrent low grade CLL and recent history of COVID-19 vaccination and infection. Additionally, we review the literature and discuss the therapeutic challenges. Results A 73-years old male presented with five months of progressive fatigue, weight loss, diffuse sweating, muscle cramps, and neuropathic pain. He eventually developed bilateral upper and lower facial weakness. Patient contracted a mild COVID-19 infection two months prior and COVID- 19 vaccination one month prior to his symptom onset. His exam was remarkable for bilateral facial weakness, diffuse fasciculations and sensory neuropathy on his trunk and extremities. His diagnostic work up including bone marrow biopsy was consistent with a chronic lymphocytic leukemia (CLL)-like immunophenotype. Cerebrospinal fluid (CSF) analysis was remarkable for five WBC (lymph-dominant) and protein of 74 mg/dl. Serum paraneoplastic panel revealed positive CASPR2 antibody with a titer of 1:100. Magnetic Resonance Imaging (MRI) of the brain showed enhancement of bilateral cranial nerve VII. After lack of clinical response to IV methylprednisone (1 gram for 5 days), patient was treated with a single cycle of IV immunoglobulin (IVIG). He had complete recovery of his symptoms except for residual facial weakness. He remains stable at his six months post-treatment follow-up. Conclusions Anti-CASPR2 associated autoimmunity following COVID-19 infection or in the setting of CLL has previously been reported. However, cranial neuropathy in association with CASPR2 antibody has never been. A trial of IVIG could be beneficial in patients with viral-spike protein-induced autoimmunity and CLL who do not otherwise meet the criteria for CLL treatment.
ABSTRACT
Introduction: Viruses belonging to the SARS-COV family are known for their neurotropic properties. During the COVID-19 pandemic increasing data emerged, providing evidence for CNS and PNS engagement due to SARS-COV-2 infection. Cranial nerves as well as peripheral nerves have been described to be affected. According to some recent studies, a significant number of COVID-19 patients develop neurological manifestations. Method(s): We present a case of a 38-year-old woman suffering from left-sided facial pain and hypoesthesia, as well as paraesthesia, hypoesthesia, and pain in her left arm. One to two weeks prior to these symptoms, she presented with signs of upper respiratory tract infection and loss of taste and smell. She underwent a routine neurological examination and prior to her admission to the neurology ward she tested positive with qPCR for SARS-COV-2 in a nasopharynx swab. Subsequently she underwent brain and spinal MRI, analysis of cerebrospinal fluid (CSF) and neurophysiological examinations including nerve conduction studies and blink reflex analysis. Result(s): The brain and spinal MRI, CSF analysis and nerve conduction studies of the left arm (n. medianus, n. ulnaris, and the superficial radial nerve) and the facial nerve (CN VII) showed normal results. Normal blink reflex responses were obtained from both the supraorbital nerve and infraorbital nerve. When examining the mental nerve, normal responses were obtained from the asymptomatic right side but from the symptomatic left side both ipsilateral R2 and contralateral R2 responses were absent. This indicates an afferent non-specific lesion in the left mental nerve. Conclusion(s): When considering the course of her condition and excluding other probable causes, the symptoms were regarded to be related to her SARS-COV-2 infection. Hence, with this case report we can present objective neurophysiological evidence that a specific segment of the trigeminal nerve, in this case the mental nerve, can be affected by neuralgia due to COVID-19. It is notable that the patient did not present with symptoms of typical/classic trigeminal neuralgia. She was treated with carbamazepine and the facial pain was significantly improved. To the best of our knowledge, this is the first report of a pathological blink reflex associated with COVID-19. Copyright © 2022
ABSTRACT
Introduction: Guillain-Barre syndrome (GBS) is an acute inflammatory neuropathic illness with striking clinical manifestations and significant morbidity. Rare sporadic cases of GBS have been described following vaccination. This case in particular was temporally related to the Sinovac-CoronaVac (COVID-19) vaccine. A causal link with the vaccine is not proven but is possible and warrants further investigation. Hence, the objective of this study is to describe a case of GBS after COVID-19 vaccination. Method(s): Case report Results: 55-year-old Filipino woman presented with progressive symmetric ascending weakness of bilateral upper and lower extremities which began four weeks after receiving vaccination with the Sinovac-CoronaVac (COVID-19) vaccine. She also described concurrent facial weakness, dysphagia, and paresthesia of both feet. Fortunately, there were no clinical findings of dysautonomia. On neurological examination, she had facial diplegia, quadriparesis with lower extremity predominance, manual muscle testing revealed 4-/5 on bilateral upper limbs and 2/5 on bilateral lower limbs. The deep tendon reflexes were absent generally. The cerebrospinal fluid analysis showed protein-cytological dissociation and the nerve conduction study (NCS) revealed generalized motor axonopathy. Thus, the patient was managed as GBS, specifically the Acute Motor Axonal Polyneuropathy (AMAN) variant. She underwent plasma exchange in 5 sessions over 10 days with significant clinical improvement at a 4-week follow up visit. Conclusion(s): Only a few cases of GBS after COVID-19 vaccination have been reported. Among these, AMAN is uncommonly described. In patients with GBS, several viral and bacterial pathogens have been found in several studies but the factors that induce the immune-mediated destruction of the nerve tissues need more rigorous research.
