SPD is also known as Sensory Integration Dysfunction
A Brief Comparison of Two "Look-Alike" Disabilities
In my book, The Out-of-Sync Child, I define Sensory Processing Disorder (SPD) as the "inefficient neurological processing of information received through the senses, causing problems with learning, development, and behavior." Picture a child who has trouble processing and interpreting sensory messages about how things feel and what it feels like to be touched. Touch stimulation overwhelms this oversensitive child.
How does his problem play out? He is bothered by the label in his tee-shirt, the approach of a classmate, the lumps in his mashed potatoes, the stickiness of the play dough. Fidgeting and squirming, he pays a lot of attention to avoiding these ordinary sensations. Meanwhile, he is unable to pay much attention at all to the teacher's words or to playground rules.
Say a child with another form of SPD dysfunction has trouble processing movement and balance sensations. Say this under-responsive child needs to move around — much more than her peers — in order to rev up and get going. What is the fallout of her problem? This impulsive "bumper and crasher" craves intense, vigorous movement. She often rocks, sways, twirls, jumps, climbs, leaps, gyrates and gets into upside-down positions. She pays a lot of attention to satisfying her need for movement, and not much attention to her mother's instructions or to where she left her shoes.
Inattention . . . impulsivity . . . fidgety movement . . . these can be symptoms of SPD.
Now consider my definition for Attention Deficit Disorder (ADD): "a neurological syndrome characterized by serious and persistent inattention and impulsivity. When constant, fidgety movement (hyperactivity) is an additional characteristic, the syndrome is called Attention Deficit Disorder with Hyperactivity (ADHD)."
Inattention . . . impulsivity . . . fidgety movement . . . these are definitely symptoms of ADD/ADHD — and of many other difficulties, as well.
In my book, I discuss other "look-alike" conditions which share symptoms with SPD (pp. 17-20). SPD may look like ADHD, and some symptoms may overlap. However, optimum treatment for the two problems is different. Before jumping to conclusions and leaping to drug therapy, parents and professionals need to look at the whole child. Then, they can thoughtfully determine what will help the most.
If the child is frequently — but not always — inattentive, it is useful to ask some questions: Where, when, and how often does this inattention occur? What is the stimulus? What does the child do as self-therapy? What is happening — or not happening — when the child concentrates well? What does the child need, and what helps?
An overloaded child needs less stimulation. So, dim the lights and turn down the radio. Comfort him with "deep pressure" bear hugs. Help him fix up a retreat, with pillows and blankets, under the dining room table.
An under-responsive child needs more sensory stimulation. So, take her to the playground each day, jog together around the block, engage her in gentle roughhousing, and provide her with a chinning bar, a punching bag, and a trampoline.
SPD is a neurological problem which affects behavior and learning. Medicine doesn't fix it, but, often, occupational therapy helps. This therapy addresses the child's underlying difficulties processing sensations rather than just the symptoms of inattention.
Not psychostimulants, but a good sensory diet may be a major component in treating the child with an attention problem. (A sensory diet is prescribed by an occupational therapist and is rich in safe, appropriate, and enjoyable touch, pressure and movement experiences.) Taking a conservative approach can't hurt and often helps the inattentive child whose problem is not ADD, but developmentally delayed sensory processing.
Why A "Hands-On" Sensory Diet?
Birds gotta sing, fish gotta swim, and kids gotta MOVE and TOUCH. Moving and touching are how children first learn about the environment around them. Feeling a blanket with their skin, touching a flower petal, stretching their arms up toward the ceiling, climbing a jungle gym, and running in great circles are ways that children gain the important information they require to function well.
Preschoolers need a variety of active, hands-on experiences, because kids are sensorimotor learners. Sensorimotor means that sensory information comes in, and motor responses go out. For example, the feel of a bunny's soft fur is a pleasant sensation, and stroking the bunny is the appropriate motor response. Children need many concrete lessons, such as bunny-stroking, before they are developmentally ready to gather abstract information, such as ABCs and math facts.
Using many senses leads to healthy sensory integration. Sensory integration is the neurological process of taking in sensory information, organizing this information in the central nervous system, and using the information to function smoothly in daily life. Sensory integration is a never-ending building process: as children gain competence, their sensory integration improves. Thus, the more kids do, the more they can do.
Nature's educational plan is for young children to "do," by touching and being touched, and by moving and being moved. Sensations of touch and movement come through seven sensory systems, but we think of three basic systems when we talk about Sensory Processing Disorder:
At home and at preschool, children should be actively participating in hands-on, sensorimotor experiences all through the day. Passive participation — e.g., watching others play or sitting in front of an electronic screen — will not encourage our children to become competent and confident learners.
Some Ingredients For A Hands-On, Body-On Sensory Diet
Here are some typical sensorimotor experiences which could be selected for a "sensory diet" to help a young child stay organized and alert for interaction and learning. Occupational therapists will recommend a sensory diet after carefully observing your child to see what mix of calming and energizing experiences each child needs to remain attentive and on task throughout the day.
