Memory Deficits in Adults with Atopic Dermatitis: The Overlooked Impact of Sleep Disturbance

Background: Sleep disturbance is highly prevalent in atopic dermatitis (AD), yet its contribution to memory deficits remains underexplored. Aims: To characterize sleep disturbance and memory dysfunction in adults with AD, examine their relationship with disease severity, and identify predictors of impaired memory. Methods: A cross-sectional study was conducted among adult patients with AD . Sleep and memory were assessed using the Pittsburgh Sleep Quality Index (PSQI) and Everyday Memory Questionnaire-Revised (EMQ-R). Associations were analyzed using multivariate models. Results: Seventy-eight patients participated. Poor sleep quality was reported in 77%, and 64% exhibited memory dysfunction. Sleep latency increased with disease severity (mild: 32 ± 13 minutes; moderate: 49 ± 34 minutes; severe: 63 ± 33 minutes; P
