Introduction: Since May 3^rd, 2023, Manipur, a state located in the northeastern state of India, has witnessed a significant increase in internally displaced persons (IDPs) due to the Meitei-Kuki ethnic conflict. This has led to an increase in internal displacement of people within the state due to violence and instability of both the communities in the safer regions. These IDPs often faced a myriad of challenges related to physical, mental health and well-being. The study aims to explore the prevalence of mental health issues, i.e. anxiety, depression, PTSD and suicidal ideation faced by the IDPs, distribution among the genders, and various age groups to provide evidence on the existing knowledge of mental health in northeast India.Methods: The study employs a descriptive–exploratory research design and focuses on the IDPs residing in the formal relief camp of Manipur based on the secondary data available in the Government Official Records. Results: Anxiety and depression are highly prevalent among the IDPs. Women, middle-aged individuals, and older individuals are the most affected ones. Conclusion: The study highlighted a high prevalence of anxiety, depression, and mixed anxiety depression disorders. If left unattended, these disorders will deteriorate and may ultimately lead to PTSD and suicidal ideation. Addressing all the challenges through accessible health services and further research will be crucial in improving the well-being of the affected populations.
