Research suggests a notable connection between ADHD and allergies, particularly allergic rhinitis. Studies indicate that children with ADHD are more likely to experience allergic conditions such as rhinitis, asthma, and eczema.

 

This overlap may stem from shared genetic and environmental factors or immune system interactions that affect brain and behavioural development.

 

 

Key findings include:

 

1.Allergic Rhinitis and ADHD: A systematic review found a significant correlation between ADHD and allergic rhinitis. The relationship is influenced by factors such as gender (stronger in females) and age (more pronounced in children aged 9–15). Treating allergies, particularly with antihistamines or intranasal corticosteroids, can alleviate ADHD symptoms like inattention and hyperactivity in some cases.

 

2.Impact of Allergies on ADHD Symptoms: Allergic reactions can exacerbate ADHD-related issues through impaired focus, sleep disturbances, and fatigue. These symptoms can make self-regulation even more challenging for individuals with ADHD.

 

3.Shared Mechanisms: Both ADHD and allergic conditions may involve inflammatory processes and disruptions in neurotransmitters like dopamine and norepinephrine. For example, inflammatory cytokines from allergies can affect the brain’s neurochemical balance, potentially worsening ADHD symptoms.

 

4.Treatment Interplay: Effective management of allergies can improve overall outcomes for individuals with ADHD. However, some antihistamines may worsen ADHD symptoms, so careful selection of treatments is essential.

 

This interplay underscores the importance of a holistic approach to treatment, considering both neurological and immunological factors.
