Sensory processing disorder (SPD) may affect only one sense, like hearing or sight, or it can impact multiple senses. For example, a child may react strongly to different textures of clothing while another may over-respond to loud sounds. Many children who have SPD are not immediately diagnosed with the condition as the disorder can be mistaken for ADHD. Many people reach adulthood without a proper diagnosis and may struggle with the symptoms of the disorder.
There are three subtypes of SPD: sensory modulation disorder, sensory-based motor disorder, and sensory discrimination disorder. In today’s post we’ll be reviewing 2 subtypes of SPD: sensory modulation disorder and sensory-based motor disorder.
|Sensory Modulation Disorder||Difficulty regulating responses to sensory stimuli|
|Sensory Over-Responsive||Predisposition to respond too much, too soon, or for too long to sensory stimuli most people find quite tolerable|
|Sensory Under-Responsive||Predisposition to be unaware of sensory stimuli, to have a delay before responding, responses are muted or responds with less intensity compared to the average person|
|Sensory Craving||Driven to obtain sensory stimulation, but getting the stimulation results in disorganization and does not satisfy the drive for more|
|Sensory-Based Motor Disorder||Difficulty with balance, motor coordination, and the performance of skilled, non-habitual and/or habitual motor tasks|
|Postural Disorder||Impaired perception of position of body position; poorly developed movement patterns that depend on core stability. Thus, appears weak and/or has poor endurance|
|Dyspraxia||Difficulty thinking of, planning and/or executing skilled movements especially novel movement patterns|

This is really just a basic overview. SPD can affect all 8 senses and present in a variety of combinations. In future posts, we’ll talk about what the 8 senses are and sensory discrimination disorder.
