COVID-19 and neurocognitive disorders

Abstract

Purpose of review: The COVID-19 infection results in various viral-related physical and mental health problems, joined with the long-term psychological impact of the pandemic in general. However, the accompanying neurocognitive changes remain poorly understood.

Recent findings: We synthetize the current knowledge of viral (SARS-CoV-2) induced inflammation, mechanisms to viral entry into the central nervous system and altered neurotransmitter systems to provide an informed neurobiological explanation for the rise of neurocognitive disorders (defined as per the DSM-5 criteria).

Summary: The mild and major neurocognitive disorder symptoms due to the COVID-19 pandemic provide a unique opportunity to address the early changes underlying neurocognitive impairment at both clinical and molecular level. We discuss the utilization of the available evidence for their management and future novel therapeutic opportunities.

    2. This study was based on TriNetX Analytics Network that contains anonymized data from electronic health records in 54 healthcare organizations in the USA, totalling 69.8 million patients. The analysis included 62,354 patients diagnosed with COVID-19 between 20 January and 1 August 2020. The authors present incidence and hazard ratios measures for psychiatric disorders, dementia and insomnia, during the first 14--90 days after a diagnosis of COVID-19.

    2. In this observational case series, 204 patients with Alzheimer's disease and frontotemporal dementia were enrolled and the frequency and mortality of COVID-19 determined. COVID-19 occurred in 7.3% of patients living at home and 72.0% of those living at care homes. Living in care facilities and diagnosis of Alzheimer's disease were independently associated with a higher probability of death.
