ABSTRACT

Background:

Atopic dermatitis (AD) is a chronic inflammatory skin condition, affecting a significant percentage of the global population. Emerging research suggests a potential link between AD and neurodevelopmental disorders like attention deficit hyperactivity disorder (ADHD). However, there is a lack of comprehensive studies within the Saudi Arabian population examining this association.

Objective:

This study aims to determine the prevalence of ADHD among patients with AD in Saudi Arabia and to explore potential associations with demographic and clinical factors.

Methods:

In this cross-sectional, multi-center study conducted between May and November 2024, 419 patients with atopic dermatitis were recruited from various hospitals in Saudi Arabia. Children were screened for ADHD symptoms using the ADHD Rating Scale-5, while adults were assessed with the Adult Self-Report Scale (ASRS-v1.1). Logistic regression was used to evaluate the influence of AD severity, age, gender, nationality, and body mass index on the likelihood of ADHD symptoms.

Results:

A total of 419 patients with atopic dermatitis were included, of whom 234 (55.8%) were children and 185 (44.2%) were adults; 57% were female and 85.9% were Saudi nationals. ADHD symptoms were identified in 84 patients (20%), with a slightly higher prevalence among children (20.9%) compared to adults (18.9%) (p = .61). No significant associations were found between ADHD symptoms and gender, nationality, BMI, or AD severity in either age group. Moderate to severe AD was more common among adults (25.9%) than children (17.9%) (p = 0.048).

Conclusions:

This study found that 20% of patients with atopic dermatitis screened positive for ADHD symptoms, with slightly higher rates in children than adults. No significant associations were observed between ADHD symptoms and gender, nationality, BMI, or AD severity. Although no significant clinical predictors were identified, the findings emphasize the need for ADHD screening in AD patients, particularly in regions with high AD prevalence. Future longitudinal studies should explore underlying mechanisms and assess how managing one condition may influence the other.
