At the Mental Health World Conference (MHWC 2026), this session brings together addiction medicine experts, psychiatrists, psychologists, and public health practitioners to explore the multifaceted interaction between substance use and co-occurring mental disorders. Topics will include integrated treatment systems, harm reduction approaches, new pharmacological developments, and community-based systems of care for special populations.
Another interesting topic to be covered at the MHWC 2026 conference concerns the complex interaction between substance abuse disorder and the co-occurrence of other mental health conditions, which is also known as a dual diagnosis. Professionals specializing in addiction medicine, psychiatry, psychology, and public health will examine the interactions between biological, psychological, and social variables that might lead to dual diagnosis. Among the newest discoveries regarding possible mechanisms contributing to dual diagnoses, it is worth noting research findings on brain abnormalities. In particular, reward pathway dysregulation, stress response system dysfunction, and genetic risk factors will be considered to develop new approaches to diagnosing the disorders.
