Are there links between allergies and ADHD?

Research has started to uncover possible connections between allergies and ADHD, suggesting that the body’s immune response may play a role in brain development and behaviour. Children with childhood allergies, such as asthma, eczema, or hay fever, appear to have a higher likelihood of experiencing attention and hyperactivity challenges. Understanding the behavioural effects of allergies may help families recognise and manage overlapping symptoms.

How Allergies May Influence ADHD 

Here is what we know about allergies and ADHD. 

Immune system interaction 

Chronic inflammation and heightened immune response in allergic conditions might affect brain regions responsible for focus and emotional regulation. 

Sleep disruption from allergies 

Symptoms like itching, congestion, and breathing difficulties can disturb sleep, worsening attention and mood during the day. 

Behavioural effects of discomfort 

Childhood allergies can make children irritable, distracted, and more impulsive behaviours that overlap with ADHD. 

Shared genetic and environmental factors 

Both ADHD and allergic conditions may stem partly from common genetic predispositions or environmental exposures. 

If you suspect allergies are influencing ADHD symptoms, it’s worth discussing with a professional. Visit providers like ADHD Certify for personal consultations and advice on managing allergies and ADHD together.
