Sensory Processing Disorders: An Exploration


Sensory Processing Disorders, commonly abbreviated as SPD, are conditions that affect how individuals perceive and respond to sensory stimuli from their environment. These disorders are often misunderstood and can significantly impact a person’s daily life. In this comprehensive overview, we will delve into the world of sensory processing disorders, providing a clear and accessible explanation for those new to the subject. It is important to note that this article presents a layman’s overview of sensory processing disorder. It does not purport to offer definitive advice or conclusions but aims to encourage further research in this field.


What Are Sensory Processing Disorders?


Sensory Processing Disorders, also referred to as Sensory Integration Disorders, are neurological conditions that affect how the brain processes and responds to sensory information received through the five main senses: sight, sound, taste, smell, and touch. Additionally, these disorders can influence the perception of movement and balance, known as proprioception (our sense of body position, aiding coordination and movement) and vestibular (the system that controls balance and spatial orientation in humans) senses, respectively.


Individuals with SPD may experience sensory information differently than most people. They might be hypersensitive, making them more responsive to sensory stimuli, or hyposensitive, causing them to be less responsive. These differences can manifest in various ways, impacting an individual’s ability to engage in daily activities.


Types of Sensory Processing Disorders


Sensory Processing Disorders encompass a range of specific conditions, each affecting different sensory domains. The following is an overview of these types:


  1. Sensory Modulation Disorder: This involves difficulties in regulating and responding appropriately to sensory input. Individuals may overreact or underreact to sensory stimuli, leading to emotional and behavioural challenges. For example, a child might become agitated in response to a gentle touch.


  1. Sensory Discrimination Disorder: People with this disorder struggle to distinguish between different sensory stimuli. They may find it challenging to differentiate between similar textures, tastes, or sounds.


  1. Sensory-Based Motor Disorder: This relates to difficulties in motor coordination, where sensory issues affect an individual’s ability to perform tasks that involve balance, muscle control, and fine motor skills.


  1. Sensory-Based Feeding Disorder: Often seen in children, this disorder involves an aversion to certain textures, tastes, or smells, which can lead to feeding difficulties and nutritional challenges.


  1. Vestibular and Proprioceptive Dysfunction: These disorders affect an individual’s sense of balance and body position. People with vestibular issues may experience dizziness or imbalance, while proprioceptive issues can lead to challenges in understanding one’s body in space.


Causes and Symptoms

The exact causes of SPD are not fully understood, but it is believed to be a result of a combination of genetic and environmental factors. Symptoms of sensory processing disorders can vary widely and may include:



Diagnosis and Evaluation

Diagnosing SPD can be difficult as it often co-occurs with other conditions like Autism Spectrum Disorder, ADHD, or developmental delays. A comprehensive evaluation by a occupational therapist with other relevant professionals, is essential to determine the presence and specific type of sensory processing disorder. It is important to note that while there are some guidelines and checklists available, SPD remains a somewhat controversial and evolving diagnosis in the medical and psychological communities. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5), used for diagnosing many mental health conditions, does not include SPD as a distinct diagnosis, which adds to the complexity of its diagnosis.



Treatment and Management

Treatment approaches for sensory processing disorders are tailored to the individual’s specific needs and symptoms. Some common interventions include:





Living with SPD

Living with SPD can present daily challenges, but with the right support and strategies, individuals can lead fulfilling lives. It’s crucial to create a supportive and understanding environment for those with sensory processing disorders. Additionally, raising awareness about SPD is essential to reduce stigmatization and promote early diagnosis and intervention.


In conclusion, Sensory Processing Disorders are complex neurological conditions that affect how individuals perceive and respond to sensory stimuli. Understanding the various types, causes, and symptoms is crucial in providing appropriate support and intervention. By embracing a multidisciplinary approach and fostering awareness, we can improve the quality of life for those children and adults affected by SPD.
