INTRODUCTION: Presently the COVID-19 pandemic is raging through the United States and worldwide. This enigmatic virus characteristically affects the respiratory system. Atypical presentations, such as gastrointestinal symptoms, and cases of encephalopathy have also been reported. However, psychiatric symptoms as the initial presenting feature is novel. We describe one such case. CASE PRESENTATION: 53-year-old man with no prior psychiatric or significant medical history was brought to the emergency department after ingesting bleach in an apparent suicide attempt. On initial presentation, the patient was uncooperative and withdrawn, though alert and oriented. He subsequently developed fever, tachycardia, elevated blood urea nitrogen and transaminases. SARS CoV-2 was confirmed on RT-PCR. Neurological examination was non-contributory. As his clinical condition improved, the patient reported that his initial symptom was an auditory hallucination telling him to jump from a bridge or ingest bleach. He reported that the increasing intensity of his auditory hallucinations led him to act upon it. He denied mood symptoms or suicidal ideation. The hallucinations did not recur during the hospital course, but he required 3 doses of antipsychotic medication for agitation. After improvement of his SARS CoV-2 infection, he was free of psychiatric symptoms and was discharged to a subacute rehabilitation center. CONCLUSION: This case indicates that what appears as a sudden onset of a psychiatric illness in the current context may be an initial manifestation of a developing COVID illness.

At the time of writing this case report in the second week of May 2020, there have been 1,409,452 confirmed cases of coronavirus disease 2019 in the United States and over 4.5 million confirmed cases worldwide. 1 Most patients who have COVID-19 present initially with fever (83-99%), cough (59-82%), fatigue (44-70%), anorexia (40-84%), and shortness of breath (31-40%). 2 However, as we begin to learn more about this virus and disease, we are seeing that the signs and symptoms present at illness onset may vary widely. Atypical presentations have been described in the literature and there have been numerous cases of delayed presentation of fever and respiratory symptoms. One atypical presentation of COVID-19 has been gastrointestinal symptoms, such as diarrhea and nausea, prior to development of respiratory symptoms. 3 Recent literature is beginning to shed light on the impact of COVID-19 on the nervous system. Common neurological features reported include headache, dizziness, anosmia, hypogeusia, and more serious complications during disease progression including seizure and stroke. 4 Patients with COVID-19 can also present with encephalopathy and delirium. 5 However, to our knowledge psychiatric symptoms as the initial manifestation of COVID-19 have not been described to date. There is some literature on the relation of psychosis and previous pandemics. In drawing a comparison to the 1918 pandemic caused by the H1N1 virus, the association of influenza and psychoses in patients who were admitted to the Boston Psychopathic Hospital in 1918 was studied by Karl A.

Menninger. 6 The psychiatric sequelae due to COVID-19 are yet to be discovered. We present in this case report a medically healthy patient with no premorbid psychiatric history who developed command suicidal hallucination as the initial manifestation of COVID-19.

A 53-year-old man with no prior medical or psychiatric history presented to the emergency department after an apparent suicide attempt, having ingested an unknown quantity from a bottle of bleach. He was alert and oriented, though mostly uncooperative due to epigastric pain on initial examination. He refused to answer most of the primary team's questions. Examination of the patient's mouth revealed a right lower lip abrasion with no oropharyngeal injuries or erosions.

Per collateral information obtained from the patient's wife who accompanied him, she was bewildered by the patient's action. She reported that her husband had been "healthy, normal, happy, never done anything like this before." She also stated that the patient had not complained of any fever, cough, or recent illness. She was unsure why the patient would have ingested bleach. The patient was not cooperative with the psychiatric interview due to his apparent cultural stigma. He reiterated, "I don't need a shrink; I'm not crazy." His urine toxicology was negative. Our initial recommendation was psychiatric hospitalization after medical clearance. While still in the emergency department, the patient developed fever (temperature 101.7°F), tachycardia (heart rate 120 beats/minute), and elevated blood urea nitrogen (BUN) and transaminases. Chest X-ray revealed an opacity in the upper lobe of the right lung, indicative of a possible COVID-19 pneumonia. The patient was admitted to the medical service for further workup and management. He was started on ceftriaxone 1,000 mg intravenous (IV) daily, azithromycin 250 mg po daily, and hydroxychloroquine 200 mg po twice daily.

During the next five days, he continued to be uncooperative. He refused his meals due to reported poor appetite and refused IV medications intermittently. He was observed by nursing staff to be "chanting and singing to himself" but was able to be verbally redirected. He denied suicidal ideation, intent, or plan.

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was confirmed by COVID-19 real time polymerase chain reaction (RT-PCR) from nasopharyngeal swab. There was no focal neurological deficit and no apparent cognitive impairment. Montreal Cognitive Assessment was performed on hospital day #6. He scored 26 out of 30, losing one point each for the modified trail making test, naming the rhinoceros, serial 7 subtractions, and delayed recall. He received a total of 3 doses of olanzapine 5 mg intramuscular injection intermittently to manage agitation on hospital day #3, 7, and 8.

On hospital day #6, he developed worsening hypoxic respiratory failure due to COVID-19. He developed rigors and continued to have high grade fevers. The patient began to improve on hospital day #10, requiring less supplemental oxygen and became more cooperative with examinations. Computed tomography of the head without contrast was performed on hospital day #12 and the findings were unremarkable. Lumbar puncture was not performed.

On hospital day #12, the patient was able to discuss his auditory hallucinations in meaningful detail. The patient reported that his initial symptom was a repeated command auditory hallucination of an unrecognizable singular voice that started one day prior to him ingesting bleach. He was unsure about the gender of the voice but noted that it sounded "demonic" and stated that he heard the voice externally. The voice initially told the patient to "Go jump from the bridge" and later told him, "Go to the kitchen and drink bleach." He reported feeling confused and terrified. He explained that he ultimately ingested bleach not because of suicidal intent, but because "the voice got louder and more forceful." The patient denied experiencing auditory hallucinations in the past and denied recurrence of hallucinations during his hospitalization. He also denied use of illicit substances, alcohol, or tobacco. He denied present or past suicidal ideation or suicidal attempts. He was goal-directed, affectively reactive, and future-oriented. He denied past or current symptoms of mood or anxiety disorders.

Since the implementation of stay-at-home directives, the patient reported that he had been able to continue his work remotely as an office clerk. His wife, a schoolteacher, and his 21-year-old web developer son were also conducting work from home. Leading to his hospitalization, he noted some general anxiety about COVID-19 but stated that he felt fortunate to be at home and was trying to keep his "spirit and body occupied." He denied other acute stressors in his relationships, employment, or finances.

The patient's account of history and absence of prior psychiatric illness was supported by collateral information obtained from the patient's wife and his primary care provider. The patient was psychiatrically cleared for discharge to a subacute rehabilitation center. Discharge impression was psychotic disorder due to another medical condition. 7

The perceptional disturbance in our patient which led to the self-harm attempt meets the formal characteristics of a hallucination -i) occurred in external objective space, ii) the voice was clearly delineated, iii) sensory elements were full and fresh, iv) the perception was constant and remained unaltered, and v) the perception was independent of will. 8 The absence of prior psychiatric illness or significant stressors, his initial experience of command auditory hallucinations, the subsequent development of COVID-19 symptoms, and the later disappearance of hallucinations suggest that the command auditory hallucinations were the first symptoms of his developing COVID illness. This patient's command hallucinations to ingest bleach were experienced 22 days before President Donald Trump made comments about getting a disinfectant into the body as a potential cure for COVID- 19. 9 While there are reports of encephalopathy due to COVID-19 5 , we are not aware of any prior report of hallucinations being the presenting symptom.

Among the differential diagnoses for our case, delirium, stress-induced "reactive" psychosis, and catatonia were all considered. First, delirium 10 , a clinical expression of encephalopathy, was plausible in our case. The patient had minimal cooperation initially, intermittent refusal of medications and meals, and required antipsychotic medication for management of agitation. Earlier cognitive testing was not feasible due to patient noncooperation. However, he remained alert and oriented throughout his hospital stay. The patient's uncooperative behavior was hypothesized to be in part due to his stigma of psychiatry with a likely component of subsyndromal delirium. 11 Second, a stress-induced psychotic reaction was determined to be lower on the differential after review of his relatively benign account of recent psychosocial stressors. Third, there is literature on catatonia-like syndromes due to viral encephalitis 12 and anecdotal cases of catatonia in the setting of COVID-19. This patient displayed negativism toward interventions, withdrawn behavior, and decreased oral intake, but not waxy stability, excitement, stupor, mutism, echolalia or echopraxia. 13 The COVID-19 pandemic has been quite novel in its protean manifestation, including the neurological ones. Several mechanisms have been proposed for neurologic symptoms. 14 One such mechanism is direct viral injury to the neurons akin to herpes simplex virus (HSV) encephalitis. 15 

CoV-2 has the capacity to bind to angiotensin converting enzyme 2 (ACE-2) receptors. These receptors, although highly expressed in epithelial cells of the respiratory and digestive systems, are also expressed in neurons and glial cells in the CNS.

Cytokine storm may lead to acute or subacute central nervous system (CNS) involvement, including encephalopathy. Current available evidence suggests that chronic neuroinflammation associated with high levels of cytokines and chemokines is involved in the pathogenesis of neurodegenerative diseases such as multiple sclerosis, Parkinson's disease, and Alzheimer disease. 16 Neuroinflammation has also been found to play a role in the pathogenesis of psychiatric diseases including affective disorders, schizophrenia spectrum disorders, and substance abuse, especially alcohol abuse. 17 Proinflammatory cytokine dysregulation can induce changes in neurotransmitter metabolism, cause hypothalamic-pituitaryadrenal axis dysregulation, or alter neuroplasticity.

Molecular mimicry leading to bystander effect like Guillain-Barre syndrome is another proposed mechanism. 18 In susceptible individuals, an aberrant immune response may become cross-reactive with both viral antigen and self-antigen. Systemic illness leading to CNS manifestations may also be contributory. 19 An example of such a mechanism would be peripheral myeloid cells infected by SARS-CoV-2 which can subsequently transmigrate to the CNS under conditions of increased blood brain barrier permeability due to inflammation and psychological stress.

Our case indicates that what appears as a sudden onset of a psychiatric illness in the current context may be an initial manifestation of a developing COVID-19 illness. Testing for COVID-19 and a period of observation in the medical setting prior to psychiatric hospitalization may be warranted in such cases. Considerations should be made for delirium, encephalopathy, catatonia, and stress-induced psychotic reaction. Management of such patients may benefit from neurology consultation, neuroimaging, electroencephalogram (EEG), formal neuropsychological testing, and lumbar puncture. Also, the neuropathological mechanisms of such cases need to be explored.
