Artificial Intelligence in Mental Health Support: Opportunities, Applications, and Ethical Challenges

Mental health conditions have become one of the most urgent public health challenges worldwide, affecting nearly one billion people and creating substantial social and economic burdens. Despite increasing demand for psychological services, barriers such as financial costs, shortages of mental health professionals, geographical inequalities, and social stigma prevent many individuals from receiving timely support. This paper examines the biological, psychological, and environmental factors contributing to mental disorders and evaluates the potential role of artificial intelligence (AI) conversational models in mental health support. It argues that AI cannot replace licensed clinicians but can serve as a complementary tool by improving accessibility, providing continuous communication, offering privacy, and delivering personalized psychoeducation. Particular attention is given to autism spectrum disorder (ASD), where AI's predictable communication style may support communication practice and reduce social pressure. The paper also discusses AI-assisted interventions based on cognitive behavioral therapy (CBT) and examines ethical challenges, including privacy, algorithmic bias, and clinical responsibility. Overall, responsible cooperation between AI technologies and healthcare professionals may improve the accessibility and effectiveness of future mental healthcare.
