What is Sensory Processing Disorder?

So what exactly IS Sensory Processing Disorder? A lot of people ask me this question and I've found it really hard to explain. This is from SPD Australia;

"SENSORY PROCESSING DISORDER (SPD) is a complex neurological condition that impairs the functional skills of 1 in 20 children. People with Sensory Processing Disorder (SPD) misinterpret everyday sensory information, such as touch, sound and movement. They may feel overwhelmed by sensory information, may seek out sensory experiences or may avoid certain experiences.

People with SPD experience their world as either Hypersensitive (over reactive, sensory avoidance) or Hyposensitive (under reactive, sensory seeker). They may also present with motor skill problems. They may react with strong emotional behaviours and experience what may be described as ‘melt downs’.

The brain and nervous system receive input from body parts as well as from the outside world. The central nervous system is also a means of transmitting messages throughout the body and functions somewhat like a computer system. The messages that are transmitted, however, affect functions such as muscle movement, coordination, learning, memory, emotion, behavior and thought. As with a computer, a breakdown or malfunction in one part of the system often affects other functions of the system.

Sensations from hearing, vision, taste, smell, touch, pressure, and movement provide the input to the brain which is organized for movement, cognition and learning. The richness of the sensory environment and the interactive experience of the individual with the environment contribute to optimal development of function.

When there is a Sensory Processing dysfunction, it is hypothesized that the brain does not process or organise the flow of sensory impulses in a way that gives the child precise information about themselves and their world.

As a result, learning can be difficult and children may feel uncomfortable, or have difficulty coping with the stress of daily sensory and organizational demands. This often results in additional or behavioural difficulties."

So what does this mean for us? It means Asher doesn't like loud noises, vacuums send him hiding under the table, crying hysterically with his hands over his ears. Hair washing can cause him to vomit and self harm. He doesn't like shopping centres because things are too tall, too loud, too bright. He has frequent meltdowns. He needs time to un-wind and is limited with the amount of stimulation he can handle in a day. He needs help to regulate his senses. We need to follow a 'sensory diet' to help give him the sensory input he craves on a day-to-day basis. He needs extra help trying new things, with play and learning how to control his body.

But you know what? He's a happy, bright, beautiful little boy who doesn't understand the words 'too loud!'. He loves to run and bounce. Asher is affectionate when it suits him, as long as you know just how to give him the right type of hug! He enjoys outdoor play. Dora the Explorer is his current favourite TV show, followed very closely by Diego.

Asher is a very special little guy and I am so blessed to be his mumma.
