BACKGROUND: Chronic pain, opioid use, and mental health disorders frequently co-occur in older adults, forming a complex and mutually reinforcing triad. Neurobiological ageing processes-such as neuroinflammation, dopaminergic decline, and impaired top-down regulation-may increase vulnerability to maladaptive coping strategies, including opioid misuse. This review aims to integrate neurobiological, affective, and clinical evidence to propose a unified neuropsychiatric framework for understanding the intersection between chronic pain, emotional distress, and opioid vulnerability in later life, while highlighting implications for integrated treatment and opioid stewardship. METHODS: This structured narrative review synthesised interdisciplinary evidence from neuroscience, geriatric psychiatry, and pain medicine. The literature was thematically organised to examine shared neurobiological and psychosocial mechanisms underlying chronic pain, affective disorders, and opioid use disorder (OUD) in older adults, with attention to treatment strategies and stewardship principles. RESULTS: Converging evidence suggests a neuroprogressive continuum linking chronic pain, emotional distress, opioid misuse, and cognitive decline. Key mechanisms include frontolimbic dysfunction, impaired reward processing, and chronic allostatic load. Therapeutic approaches that integrate analgesia with emotional regulation-such as buprenorphine, serotonin-noradrenaline reuptake inhibitors (SNRIs), and multimodal tapering strategies-may offer neuroprotective benefits. Effective opioid stewardship appears to require integrated functional, cognitive, and affective monitoring. CONCLUSIONS: Pain management in older adults may benefit from moving beyond symptom-focused approaches toward a neuropsychiatric model of care aimed at preserving homeostatic balance across sensory, emotional, and motivational domains. Within this framework, opioid therapy can be conceptualised as a potential means of functional and neuroaffective restoration, rather than solely as a strategy for risk reduction.
