It's the reason why Declan wears noise-blocking headphones on the subway and in movie theatres, and leaves noisy birthday parties early (AVOIDING LOUD SOUNDS). It's the reason he lays his body upside down on the stairs, asks to be held up by his feet, and repeatedly spins around on our office desk chair (SEEKING VESTBULAR INPUT). It's the reason he eats lots of crunchy foods and avoids lots of smooth, creamy foods (SEEKING AND AVOIDING PROPRIOCEPTION). It's the reason he cannot see the shoes that are his in the line of family shoes at the garage door, or cannot find the child hiding just their face behind the potted plant during hide and seek (VISUAL DISCRIMINATION). It's the reason he loves to hurl his body onto the couch or lay under all of the couch's cushions (SEEKING PROPRIOCEPTION), and one of the reasons he insists on putting on and taking of his pants without unbuttoning them (AVOIDING FINE MOTOR PROPRIOCEPTION). Its also the reason that he ducks away from the brush when we brush his hair (AVOIDING CERTAIN KINDS OF TOUCH). It is called a sensory processing disorder, and it is now listed in the DSM V under neurological diagnoses.
Declan's Early Intervention OT was the first to introduce us to sensory processing disorders. Until then, I had never heard of such a thing, and frankly, I was skeptical. What exactly is it? Why had I never heard of it? It took me years to begin to understand what exactly it is. Lindsay Biel, author of Raising a Sensory Smart Child, describes it well:
"We all learn through our senses. Sensory processing is how we transform sensory information from within our own bodies and the external environment into messages we can act on. It’s tempting to think of senses (touch, sight, sound, movement, body awareness, taste, and smell) as separate channels of information, but they work together to give us a reliable picture of the world and our place in it.
Right now your senses are working together. You hear background sounds and feel your clothing, chair, and the floor beneath your feet. You resist gravity to stay seated. You see letters on the screen. You filter out unimportant sensory input so you can make sense of what you are reading. If you occasionally lose focus because your shirt label is itchy, you may have a mild sensory issue. If you keep sliding off your chair, look away when you hear any noise, feel like your shirt is hurting you, or the words you are reading pulsate, you may have sensory processing disorder, also known as sensory integration dysfunction. Sensory issues affect all kinds of people—from those with developmental delays, attention and learning problems, autistic spectrum disorders and other diagnoses to those without any other issues."
When Declan's sensory needs are not addressed, he is unable to focus. Think of it as being so cold that you cannot concentrate or do your work until you do something to change that condition. That is why Declan has something called a sensory diet in place at school. It is a steady stream of activities that he engages in in order to be able to remain focused on his school work.
