Heterogeneity and Comorbidity in Atopic Dermatitis

In this concise video, Dr Peter Lio explores the multifaceted nature of atopic dermatitis. He reviews diverse lesion types and fluctuating disease course, and explains how barrier dysfunction, immune dysregulation across T-helper pathways, and neuroinflammation drive itch and chronicity, highlighting comorbidities and the need for individualized management.

• Explain that AD is a chronic, heterogeneous, multidomain disease with variable clinical morphologies, temporal patterns, and involvement of barrier, immune, and neuroinflammatory pathways

• Recognize the broader impact of AD, including sensitization and comorbidities (e.g., food allergy, asthma, sleep disturbance), and why management often needs to be individualized
