The Impact of the COVID-19 Pandemic on Mental Health Among the General Population: A Narrative Review

Abstract

The Coronavirus Disease-2019 (COVID-19) has infected millions of people worldwide, resulting in a global burden for long-term care of sufferers. The impact of COVID-19 has affected the mental health of innumerable people. Emotional, psychological, and social well-being are all parts of our mental health, influencing our thoughts, emotions, and behaviours. Additionally, it affects how people respond to stress and make good decisions. For instance, depression raises the risk of a wide range of physical health issues, especially chronic illnesses like diabetes, heart disease, and stroke. The COVID-19 pandemic has infected millions worldwide, leaving a global burden for the long-term care of COVID-19 survivors. Therefore, it is imperative to study the shortterm (post-COVID) and long-term effects of COVID-19, specifically as the local and systemic pathophysiological outcomes of other coronavirus-related diseases (such as Middle East Respiratory Syndrome - MERS and Severe Acute Respiratory Syndrome Coronavirus 2 - SARS-CoV-2) have been well-documented. Mental health was evaluated using four psychological measurement scales to assess fear of COVID-19, depression, general anxiety, and post-traumatic stress. The worldwide social and economic upheaval has resulted in the worst recession since the Great Depression. The Impact of Event Scale-Revised and the Depression, Anxiety, and Stress Scale can be used to evaluate the psychological impact and mental health status. The main themes include the biology of stress and the effect of infection on the brain. Adversity can cause anatomical and functional changes in the brain. Although cortisol, for example, can alter brain architecture, tolerable stress is mitigated by protective systems and interpersonal connections that promote adaptive coping. The risk of physical and mental illness, as well as cognitive decline, may increase due to toxic stress, which is often caused by prolonged activation. From a behavioural standpoint, it is essential to understand burnout, compassion fatigue, grief, and other psychological processes and strategies in the context of the COVID-19 pandemic. COVID-19 has adversely affected the mental states of people. The COVID-19 pandemic is associated with significantly high levels of psychological distress that meet the threshold for clinical relevance. Mitigating the harmful effects of COVID-19 on mental health is an international public health priority
