Can Sensory Processing Disorder Mimic ADHD? 

Sensory Processing Disorder (SPD) can sometimes be mistaken for ADHD due to overlapping symptoms such as focus challenges, restlessness, and difficulties with attention. However, there are distinct differences between sensory processing disorder vs ADHD that help clinicians make the correct diagnosis. While both conditions can result in distractibility and irritability, the root causes and symptom patterns are quite different. 

In sensory processing disorder vs ADHD, the key difference lies in how individuals react to sensory stimuli. People with SPD often have heightened or diminished responses to sensory input, such as light, sound, or touch. This stimuli sensitivity can cause discomfort, leading to behaviours that may appear similar to ADHD, like fidgeting or difficulty focusing. However, in ADHD, restlessness and focus challenges are primarily driven by attention regulation issues, not sensory discomfort. 

Common Symptoms: Sensory Processing Disorder vs ADHD 

Stimuli Sensitivity 

Individuals with sensory processing disorder may become overwhelmed or distressed by certain sensory stimuli, like loud noises or bright lights. In contrast, ADHD-related restlessness and inattention are not caused by sensory overload but rather by difficulties with sustaining attention or controlling impulses. 

Restlessness 

Both SPD and ADHD can lead to restlessness, but in SPD, this is often a result of sensory discomfort. In ADHD, restlessness is more likely linked to the need for constant movement due to an inability to focus. 

Focus Challenges 

While both conditions can result in difficulty maintaining focus, individuals with ADHD typically struggle with staying on task due to impulsivity or distractibility, while those with SPD may be distracted by sensory input that others do not notice. 

By recognising these differences, healthcare professionals can better distinguish between sensory processing disorder vs ADHD and ensure the correct treatment plan is followed.
