A review and meta-analysis of machine intelligence approaches for mental health issues and depression detection

Abstract

Cases of mental health issues are increasing continuously and have sped up due to COVID-19. There are high chances of developing mental health issues such as depression, anxiety, schizophrenia, and dementia after 2–3 months of COVID-19 diagnosis. In this paper, a review and meta-analysis of machine intelligence approaches—namely, machine learning, deep learning (deep learning with hybrid boosting), and machine vision methods—for mental health issues and depression detection were presented. Meta-analysis was performed in four parts. The first part focused on the publication trends, criteria for inclusion and exclusion, and the current methodological scenario. The second part was intended for the methods and their advantages and limitations. It covered mental health issues and depression detection techniques along with the challenges. The third part focused on the discussion and applicability of datasets. The fourth part focused on the complete analysis and discussion along with suggestive measures; moreover, it covered the overall analysis, including the methodological impact, result impact, current trends, and some suggestions based on the limitations and challenges.
