Living Through Aging with Co-Occurring Disorders

A Fieldwork Study at IARSA

Abstract

The Ibaraki Addiction Recovery Support Association（IARSA）was established to provide a secure living environment for individuals who were struggling to engage with recovery programs at Ibaraki DARC and who were deemed unpre-pared for independent living. Although residents present multiple and complex life challenges—and operational challenges persist—daily life within IARSA is largely stable. However, responses to growing older have emerged as a major challenge for the future.

Offered in this study is a preliminary examination of aging and its support among individuals with co-occurring disorders, defined as substance depen-dence combined with psychiatric disorders such as schizophrenia or develop-mental disorders. The analysis draws on ongoing fieldwork conducted at IARSA. Findings indicate that IARSA functions as a place where residents can live through aging, underpinned by everyday practices guided by the logic of care, emphasizing ongoing situational adjustment rather than standardized proce-dures.

At the same time, the data also reveal structural constraints: as aging pro-gresses, residents commonly encounter social exclusion in securing housing, transitioning into community life, and accessing medical and welfare resources. As a result, the responsibility for addressing these challenges often becomes dis-proportionately concentrated within IARSA. This suggests a paradoxical dynam-ic wherein IARSA enables residents’ aging while simultaneously reproducing circumstances in which they have no viable alternative but to remain. These findings call for policy and institutional designs that explicitly recognize the long-term trajectories of people with substance dependence and co-occur-ring disorders. We argue that a future-oriented system of sustained life support, grounded in the expectation that individuals will age and experience decline, is essential to ensuring equitable choices and preventing the further concentration of care burdens within singular facilities like IARSA.
