Abstract
Lewy body dementia (LBD) is a neurodegenerative disorder characterized by a combination of progressive dementia and spontaneous parkinsonian symptoms. As the second most prevalent form of neurodegenerative dementia after Alzheimer’s disease (AD), LBD necessitates a deeper understanding of its pathogenesis to enable the development of targeted therapeutic interventions. While numerous reviews focus on documenting the clinical manifestations and therapeutic modalities for LBD, animal models provide valuable insights into the underlying mechanisms and potential therapeutic strategies. In this review, we systematically analyze the hallmarks of LBD pathogenesis, genetic risk factors, clinical features, and treatment strategies. Importantly, we emphasize and critically evaluate the pivotal role of animal models in LBD research in advancing our understanding of this disorder, offering a comprehensive framework to elucidate the interactions among misfolded proteins and their role in LBD pathogenesis. Our review proposes new directions for LBD therapeutic management and facilitates the development of innovative pharmacological interventions.
