From Environment to Gene Expression: Epigenetics and the Development of Mental Health Disorders

Psychiatric disorders have multifaceted origins, involving a combination of genetic and environmental factors that contribute significantly to their development. In recent times, researchers have emphasized the role of epigenetic mechanisms as the underlying molecular foundation for how environmental factors influence biological processes. Consequently, the field of epigenetics has gained growing prominence within the realm of psychiatry as a means to understand these intricate connections. This qualitative research paper explores the role of epigenetics in mental health disorders, focusing on the impact of environmental factors on gene expression. By examining the complex interplay between nature and nurture, the study provides insights into the influence of epigenetic modifications on psychiatric conditions such as schizophrenia, bipolar disorder, and post-traumatic stress disorder (PTSD). We performed semi-structured interviews with a broad range of psychiatric, genetic, and epigenetic specialists. In order to find pertinent studies looking at how epigenetic changes affect psychiatric diseases, including schizophrenia, bipolar disorder, and PTSD, a systematic literature analysis was carried out. Additionally, the paper discusses the potential implications of epigenetic research for personalized treatment approaches and early intervention strategies. Through a comprehensive literature review and qualitative analysis of expert interviews, this study enhances our understanding of the intricate relationship between epigenetics and mental health.
