Aging is frequently surrounded by enduring myths that shape public perception, policy priorities, and the delivery of psychosocial care. Misconceptions such as the inevitability of cognitive decline, emotional rigidity, social withdrawal, and reduced psychological resilience often obscure the complex and heterogeneous realities of later life. This chapter critically examines common myths about ageing and contrasts them with contemporary scientific evidence from gerontology, psychology, and mental health research. It highlights that many psychological difficulties in later life—such as depression, anxiety, loneliness, and adjustment problems—are not inevitable consequences of aging but are often influenced by social determinants, life transitions, health conditions, and access to supportive care. The chapter also explores how ageist beliefs within families, communities, and healthcare systems can lead to underdiagnosis, undertreatment, and neglect of geriatric mental health needs. By unpacking these misconceptions, the discussion emphasizes the importance of evidence-based psychosocial interventions, including counseling, community engagement, caregiver support, and culturally responsive mental health services. Recognizing the strengths, adaptability, and psychosocial resources of older adults is essential for promoting healthy ageing and psychological well-being. The chapter ultimately argues that reframing aging through a balanced understanding of both vulnerabilities and capacities can improve geriatric mental healthcare, reduce stigma, and guide the development of more compassionate and effective psychosocial support systems for older populations.
