Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the novel coronavirus that is causing the ongoing coronavirus disease 2019 (COVID-19) pandemic, was first reported in late 2019. Since then, an unprecedented amount of new knowledge has emerged about this virus and its treatment. Although the reported symptoms of COVID-19 are primarily respiratory with acute respiratory distress syndrome, SARS-CoV-2 has also been shown to affect other organs, including brain, and there are growing reports of neuropsychiatric symptoms due to COVID-19. There are two suggested pathways for how CO-VID-19 can affect the brain and mind: the direct impact on the brain and impact mediated via stress. Direct impact on the brain is manifested as encephalitis/encephalopathy with altered mental status (AMS) and delirium. In this paper, we summarize evidence from studies of previous outbreaks and current data from the COVID-19 pandemic that describe how COVID-19 is associated with an increased prevalence of anxiety, stress, poor sleep quality, obsessive-compulsive symptoms, and depression among the general population during the pandemic. In addition, we summarize the current evidence that supports how COVID-19 can also impact the CNS directly and result in delirium, cerebrovascular events, encephalitis, unspecified encephalopathy, AMS, or peripheral neurologic disorders.

Levetiracetam is a commonly used antiepileptic medication that has been associated with the development of psychosis. Cavernomas are vascular malformations that have been associated with psychosis as well, especially in the setting of hemorrhagic transformation. This case report describes a patient with cavernomas who developed psychotic symptoms after restarting her levetiracetam at a high dose (2000 mg twice a day) without gradual uptitration. Her symptoms improved upon the reduction of the levetiracetam as well as the initiation of paliperidone. This case highlights the importance of considering the biologic and medication-related factors for the development of psychosis, as well as the importance of gradual medication adjustments.
