Latent autoimmune diabetes in adults (LADA) is a form of diabetes that shares characteristics of both Type 1 diabetes (T1D) and Type 2 diabetes (T2D). This form of diabetes is often misdiagnosed as T2D due to its slower progression and the initial non-dependence on insulin therapy. However, it is an autoimmune condition that ultimately requires insulin management. This review aims to provide a detailed understanding of LADA, discussing its epidemiology, pathogenesis, clinical presentation, diagnostic challenges, treatment strategies, and potential future therapeutic developments.
