Probing the Neuro-psychological Changes Observed with the Administration of COVID-19 Drugs

The COVID-19 virus caused countless significant alterations in the human race, the most challenging of which was respiratory and neurological disorders. Several studies were conducted to find a robust therapy for the virus, which led to a slew of additional health issues. This study aims to understand the changes in the neurological system brought about by COVID-19 drugs and highlights the drug-drug interaction between COVID-19 drugs and psychiatric drugs. Alongside this, the study focuses on the neuropsychological changes in three critical mental disorders, such as schizophrenia, Alzheimer's disease, and Parkinson's disease. The comprehensive and narrative review being performed in this paper, has brought together the relevant work done on the association of COVID-19 drugs and changes in the neurological system. For this study, a systematic search was performed on several databases such as PubMed, Scopus, and Web of Science. This study also consolidates shreds of evidence about the challenges confronted by patients having disorders like Schizophrenia, Alzheimer's disease, and Parkinson's disease. This review is based on the studies done on COVID-19 drugs from mid-2020 to date. We have identified some scopes of crucial future opportunities which could add more depth to the current knowledge on the association of COVID-19 drugs and the changes in the neurological system. This study may present scope for future work to investigate the pathophysiological changes of these disorders due to COVID-19.
