![]() ![]() In ADHD, what appears as overstimulation may sometimes be an anxiety disorder. ![]() In SPD, overstimulation is exactly that - too much of a sensory input. In contrast, the neurophysiological roots of SPD have not been linked to those neurotransmitters. In ADHD, imaging research from 2018 also showed brain alterations are present however, these have to do with structural changes in the frontal areas of the brain responsible for executive function.Įvidence from 2019 also suggests that brain chemicals (neurotransmitters) dopamine and norepinephrine play a significant role in ADHD. When you live with SPD, regions of your brain may not be receiving information correctly or efficiently, resulting in sensory processing challenges. White matter uses electrical impulses to transmit communication between parts of the brain. In the brain, there are notable differences between ADHD and SPD.Īn imaging study from 2016 showed reduced white matter in the brain is associated with SPD. Kaye-O’Connor explains that “sensory processing disorder is different from ADHD because SPD is essentially having the trait of sensory differences by itself, while ADHD consists of a more complex constellation of traits.” In the brain “You may feel a need to withdraw from the environment or shut down to reduce overwhelm,” she says.ĪDHD and Sensory processing disorder differences This can present as anything from tears to anger. Kaye-O’Connor notes both children and adults may experience episodes of increased emotionality. Other signs might not be so easily recognizable: Tantrums or emotional outbursts irritation or agitation navigating crowded settings (vestibular).shading eyes, perhaps indoors, under fluorescent lighting (visual).visible discomfort to textures or clothing tags (tactile).Overstimulation can present as something different for everyone. “For example, someone with a need for constant movement might be ADHD, or they may fit the sensory seeking profile of someone with SPD.” Signs of overstimulation “ADHD and sensory differences can sometimes look alike,” says Sharon Kaye-O’Connor, a licensed clinical social worker and psychotherapist specializing in ADHD from Manhattan, New York. They may also share characteristics that appear the same but have different underlying mechanisms. What’s more, the review noted ADHD co-occurring with oppositional defiant disorder and anxiety was a predictor of more severe sensory processing challenges.īoth ADHD and SPD often feature challenges with tactile processing and over-responsivity. In 2010, a review found sensory processing symptoms were more common in ADHD than among children not living with the condition. Over-responsivity sensory modulation is the most common.ĪDHD and Sensory processing disorder similaritiesĪDHD and SPD can have similar sensory processing symptoms. Research from 2021 shows more than half of children living with SPD experience multiple subtypes. Sensory discrimination disorder (a difficulty interpreting characteristics or subtle qualities related to one or more of the eight sensory systems).Dyspraxia, challenges related to planning and executing movements.Postural disorder, altered perception of body position and underdeveloped movement patterns.Sensory craving, an intense desire for sensory stimulation tending to end in disorganized sensory input and unsatisfied sensory craving.Under-responsivity sensory modulation, reduced sensitivity to sensory stimuli. ![]()
