Sensory Processing Disorder (SPD), previously referred to as “sensory integration dysfunction,” is a condition in which a person has difficulty processing and acting upon the information they receive through their senses. This creates difficulty with many everyday tasks. Many people with Autism Spectrum Disorder also have Sensory Processing Disorder, and symptoms of these disorders can overlap. Occupational therapists often recommend a sensory diet to treat both.
Symptoms may include:
- Having trouble falling asleep or staying asleep and wandering the house at night
- Throwing tantrums or zoning out in noisy public places
- Have trouble sitting still, focusing, or transitioning from one task to another
- Exhibiting fearful or aggressive behaviors in certain situations
- Craves tight hugs, banging into things, having people sit on him or pile things on top of him
- Covering their ears or being bothered by sounds that don’t bother others
- Constantly putting objects in the mouth past the toddler years
- May lick, taste, or chew on inedible objects
- Avoids certain textures, may hate wearing clothes
Overarching Categories
1) Sensory Perception/Discrimination Disorder
Sensory Perception/Discrimination Disorder, also known as SPD, refers to a condition where individuals struggle to accurately identify differences in objects, location, intensity, or timing within their sensory experiences. It is characterized by difficulties in processing and discriminating sensory stimuli. People with SPD may have challenges in recognizing and distinguishing subtle variations in sensory input, such as differentiating between objects, perceiving changes in spatial orientation, evaluating differences in the intensity of sensory sensations, or accurately identifying the timing of events.
Individuals with SPD may find it hard to distinguish between similar objects or textures, leading to confusion or disorientation. For instance, they may struggle to tell apart different fabrics by touch alone or have difficulty identifying specific items based on their visual appearance. Additionally, individuals with SPD may encounter problems in perceiving changes in spatial location, such as finding it challenging to navigate through environments or struggling with directionality.
Intensity discrimination can also be problematic for those with SPD. They may have difficulty discerning variations in the intensity of sensory input, whether it be sounds, lights, tastes, or physical sensations. This can result in hypersensitivity or hyposensitivity to certain stimuli, leading to avoidance or discomfort in specific sensory environments.
Furthermore, individuals with SPD may struggle to accurately perceive or understand the timing of events. This can manifest as challenges in coordinating movements, participating in conversations, or responding appropriately to changes happening around them. Difficulties with timing perception can impact various aspects of daily life, from engaging in social interactions to organizing tasks and activities.
Sensory Perception/Discrimination Disorder presents unique experiences and challenges for individuals affected by it. It is important to acknowledge and understand these difficulties in order to provide appropriate support and accommodations that can help individuals with SPD effectively navigate their sensory world.

3) Sensory Based Motor Disorder
Sensory Based Motor Disorder, also known as SBMD, is a condition characterized by difficulties in movement that are specifically related to sensory input. Individuals with SBMD may struggle to adapt to different sensory stimuli, resulting in challenges with motor skills. This means that even small movements can be problematic for them. Essentially, SBMD manifests as a disconnection or irregularity between the body's sensory processing systems and its ability to perform coordinated and precise motor actions.
