On Patterns of Neuropsychiatric Symptoms in Patients With COVID-19: A Systematic Review of Case Reports.

Coronavirus disease 2019 (COVID-19) has various neuropsychiatric manifestations, including psychotic, mood, anxiety disorders, trauma-related disorders, and cognitive disorders, such as delirium. Although the psychosocial effects of the COVID-19 pandemic contribute to an increase in psychiatric comorbidities, the COVID-19 virus is also an independent risk factor. Previous studies have revealed that the virus can invade the neural tissue, which causes an imbalance of neurotransmitters that cause neuropsychiatric symptoms. The aim of this article is to conduct a systematic review to determine the patterns of neuropsychiatric manifestations of COVID-19, discussing the frequency and its impact on pre-existing psychiatric disorders. Thirty-nine case reports were collected and analyzed for a systematic review. They were full-text, peer-reviewed journal publications from November 2020 to February 2021. Fifty-three patients were included in our study. The most frequent symptom was abnormal/bizarre behavior (50.9%), followed by agitation/aggression (49.1%), and the third most common was altered mental status and delirium (47.2%). Only 48% of our patients had a pre-existing psychiatric disorder, including three not formally diagnosed but displayed psychiatric symptoms prior to the COVID-19 infection. Findings suggest a positive correlation of new-onset psychiatric symptoms with the SARS-CoV-2 virus. However, the exact pathophysiology of the virus itself causing neuropsychiatric manifestations needs to be investigated further.

COVID-19-Induced Hypercoagulability: A Case Report.

We report a case of atherothrombotic microembolism in a 53-year-old male diagnosed with coronavirus disease 2019 (COVID-19) prior to hospital admission. Upon admission, Day 9 after diagnosis, he presented with COVID-19 pneumonia and mottling of the lower extremities. The patient was treated with anticoagulation therapy. The lower extremity angiogram showed a patent posterior tibial artery and a patent peroneal artery. Despite initial anticoagulation therapy, toe and transmetatarsal amputations were required. However, a below-the-knee amputation was subsequently required due to continued worsening and extension of mottling. Unfortunately, the patient ultimately expired from cardiopulmonary arrest before any other surgical intervention could be done.
