To understand the ways in which Black women thrive, we must consider various approaches that define their well-being. Dichotomizing aging into concrete categories as healthy/unhealthy may unintentionally isolate this group where aging successfully presents as a contradiction, thus perpetuating further marginalization.

Drawing on previous research, our combined personal and professional experiences, and the narratives of eighteen older adults diagnosed later in life (aged 60-77, 50% female), we argue that a late autism diagnosis necessitates a fundamental rethinking of aging, identity, personal relationships and appropriate support. Effective interventions must be tailored to the specific needs and strengths of this population, ensuring that late-diagnosed older adults with autism receive the recognition, understanding, and tools they require to navigate their lives with confidence and self-awareness. Our findings highlight the need for a conceptual shift in how gerontology understands and addresses autism among older adults.

The fragmented narrative structure of Barnes's work highlights themes such as cognitive decline, physical frailty, and social isolation-elements central to critical gerontology's concept of the \"Fourth Age.\" Rather than functioning solely as a representation of old age, Barnes's use of episodic forms and corporeal focalization mirrors the fragmented and multifaceted experiences associated with aging.
