How do sensory processing issues relate to hyperactive-impulsive ADHD? 

Sensory processing challenges are often closely linked with hyperactive ADHD, affecting how individuals respond to noise, light, touch, or other environmental stimuli. Those with sensory sensitivities may become overwhelmed, distracted, or emotionally reactive in environments that others find manageable. This overlap is especially noticeable in children, but it’s increasingly recognised in ADHD in adults as well. 

For many, these sensory responses intensify the core symptoms of hyperactive-impulsive ADHD , leading to greater impulsivity, restlessness, and difficulties with emotional regulation. In classrooms, children with both ADHD and sensory issues might struggle to stay seated, overreact to background noise, or avoid certain textures, all of which can disrupt academic performance. Without proper classroom support, these behaviours may be misread as defiance or inattention rather than sensory-driven responses. 

Understanding the sensory-ADHD connection 

• Heightened reactivity 
  People with sensory processing issues may be more prone to emotional outbursts or physical agitation when overwhelmed, especially in noisy, bright, or crowded settings. 

• Difficulty of self-regulating 
  Sensory input can interfere with the brain’s ability to filter distractions, making it harder for those with hyperactive ADHD to focus or manage tasks. 

• Persistence into adulthood 
  While often overlooked, many adults with ADHD continue to experience sensory sensitivities that affect work environments, relationships, and daily routines, adding complexity to managing ADHD in adults. 

Identifying sensory sensitivities as part of an ADHD profile can lead to more compassionate, tailored support. Visit providers like ADHD Certify for personalised strategies that consider sensory needs alongside core ADHD symptoms.
