For 6-yr-previous Macey, lunchtime at college shouldn’t be a lot a break from studying and math as it’s an hour rife with frustration.
Here’s how Macey’s mom, Victoria, describes Macey’s typical lunch break: In her particular-schooling classroom an hour north of San Francisco, Macey’s classmates collect at an enormous sq. desk, chattering away and snatching each other’s meals. Macey, in the meantime, is sequestered away at a small white desk in a nook, dealing with a bookshelf. She grabs the deal with of a spoon utilizing the palm of her proper hand, awkwardly scoops up rice and spills it onto her lap. She needs to be on the massive desk together with her friends, however she sits with an aide away from the opposite youngsters to attenuate distractions whereas she eats. (Victoria requested that we use her and Macey’s first names solely, to guard their privateness.)
After lunch, the youngsters spill out onto the playground. Macey, sporting a helmet, trails behind, holding her aide’s hand. She can stroll, however she typically journeys on uneven surfaces and falls over. She tends to misjudge heights, and as soon as pulled a muscle whereas climbing on playground gear. When she was three, she tripped and fell headfirst out of a sandbox, scraping her face, chipping one tooth and dislodging one other.
Macey has little hassle shifting round the home as a result of it has few stairs and her mom by no means modifications the format of the rooms. Victoria’s largest concern is that Macey’s motion troubles intrude together with her social life.
Macey is of course social: She likes interacting with adults however typically will get annoyed once they don’t perceive her. It’s much more troublesome together with her friends. One afternoon final yr, Macey watched her older brother and her cousins journey their bicycles in entrance of the home. When her brother took a break and laid his bicycle down on its aspect, Macey shuffled over and tried to climb on. “But there was no way,” Victoria recollects. “She’s wobbly, and I was afraid she would fall off and hurt herself.” Victoria gently led her daughter away from the bicycle. Tears started to stream down Macey’s face as she shouted, “I want bike!”
Macey will in all probability have these motor issues her whole life. They are a attribute function of her situation: She has an additional copy of a small stretch of DNA on chromosome 15, which causes a situation referred to as dup15q syndrome. Like most youngsters with the syndrome, Macey additionally has autism.
About 80 % of individuals with autism have some sort of movement problem, starting from clumsiness or a mechanical type of strolling to extra profound difficulties like Macey’s. “It is very, very common for children with autism to have clear impairments in their motor control,” says Stewart Mostofsky, director of the Center for Neurodevelopmental and Imaging Research on the Kennedy Krieger Institute in Baltimore, Maryland.

Despite their prevalence, motion issues will not be thought-about a core function of autism — that’s, they don’t seem to be required for an autism analysis. And they are understudied in contrast with the social difficulties and repetitive behaviors that outline the situation. “For many years, it has been ignored as a challenge that children with autism experience,” says Nicole Rinehart, director of the Deakin Child Study Centre at Deakin University in Melbourne, Australia.
A couple of scientists, together with Rinehart and Mostofsky, are exactly measuring the actions of youngsters like Macey to seek out mind options which may underlie motor difficulties. Because motor issues typically emerge in infancy, properly earlier than different options of autism, some researchers are pursuing a provocative concept: Movement issues could be one supply of the social difficulties in individuals with autism.
The concept goes like this: Children who’ve hassle exploring their environments miss out on alternatives for social interactions, making it troublesome for them to study communication and social expertise. Later on in childhood, their clumsiness prevents them from collaborating in group actions, worsening their social issues. This is a controversial concept, but when true, it signifies that therapies that train individuals with autism the way to transfer extra fluently might additionally assist them work together with others.
