Sensory Processing Disorder - what are the signs

Webpages come and go. In attempting to make sure that I can help other families get early and proper treatment for Sensory Processing Disorder, I found this information helpful and it was copied directly from the website

http://www.sensory-processing-disorder.com

Sensory integration is a normal, neurological, developmental process which begins in the womb and continues throughout one’s life. Although, it is important to note, the most influential developmental time is in the first seven years of life. Sensory processing is the process by which our brain takes in sensory input and interprets this information for use.
When talking about typical sensory processing, a productive, normal and “adaptive response” happens as:

our neurological system takes in sensory information

the brain organizes and makes sense of it

which then enables us to use it and act accordingly within our environment to achieve “increasingly complex, goal-directed actions”.

** It is this “adaptive response” which facilitates normal development.**

We, therefore use our sensory processing abilities for:

social interaction

motor skill development

focusing and attending so we can learn

If this neurological process becomes disrupted somewhere in the loop of intake, organization or output, then normal development and adaptive responses will not be achieved. 

Learning, physical and emotional development, as well as behavior will therefore be impacted; sometimes severely!

It is this disruption which yields a neurological dysfunction called Sensory Integration Dysfunction/Sensory Processing Disorder.

Keep in mind, sensory processing functions on a continuum. Please understand that we all have difficulty processing certain sensory stimuli (a certain touch, smell, taste, sound, movement etc.) and we all have sensory preferences. **It only becomes a sensory processing disorder when we are on extreme ends of the continuum or experience “disruptive, unpredictable fluctuations which significantly impact our developmental skills or everyday functioning”.**

That being said, it is important for us to break the sensory integration dysfunction symptoms down into categories based on each of the senses.These categories are: 

Tactile: the sense of touch; input from the skin receptors about touch, pressure, temperature, pain and movement of the hairs on the skin.

Vestibular: the sense of movement; input from the inner ear about equilibrium, gravitational changes, movement experiences and position in space.

Proprioception: the sense of "position"; input from the muscles and joints about body position, weight, pressure, stretch, movement and changes in position.

Auditory: input relating to sounds; one's ability to correctly perceive, discriminate, process and respond to sounds

Oral: input relating to the mouth; one's ability to correctly perceive, discriminate, process and respond to input within the mouth

Olfactory: input relating to smell; one's ability to correctly perceive, discriminate, process and respond to different odors.

Visual: input relating to sight; one's ability to correctly perceive, discriminate, process and respond to what one sees.

Since we are talking about input into the senses, it is those senses which must be looked at carefully and which will be affected. It is a careful observer (the one I wish for in every child's life!) who will pay close attention to which senses are affected and the frequency, duration, and intensity of these sensory integration dysfunction symptoms.
As I have said, we all have some types of sensory preferences and perhaps even a mild case of "dysfunction". However, it is the frequency, intensity, duration and functional impact of these symptoms which determines dysfunction.
