Study design: Case Report
Abstract: Background:Psychodermatology examines the complex bidirectional relationship between the skin and the mind. This interaction becomes particularly significant in vulnerable populations such as older adults with cognitive decline and younger individuals with psychosocial or developmental vulnerabilities.Aim: To illustrate the heterogeneity of psychodermatological presentations across the lifespan and highlight the role of cognition, insight, and psychosocial context in clinical manifestations.Methods: We present a case-based analysis of three patients with distinct psychodermatological conditions: (1) delusional parasitosis associated with cognitive decline, (2) somatic preoccupation with mild neurocognitive impairment, and (3) factitious dermatitis in a young adult with intellectual disability. Clinical, neuropsychological, and contextual factors were analyzed comparatively.Results: Older patients demonstrated dermatological symptoms linked to cognitive impairment and altered insight, including delusional infestation and psychosomatic skin complaints. In contrast, the younger patient exhibited self-inflicted lesions consistent with factitious disorder, driven by psychosocial stress and limited coping capacity. Insight varied across cases and was closely associated with cognitive status and psychosocial environment.Conclusions: Psychodermatological conditions differ significantly across age groups but share a common biopsychosocial foundation. Early cognitive screening, careful psychiatric assessment, and interdisciplinary collaboration are essential for accurate diagnosis and effective management.
