Sensory issues refer to challenges in processing or responding to sensory information from the environment. The human brain receives information from our senses (sight, sound, touch, taste, smell, and proprioception, which is the sense of body movement) and interprets it. However, for some individuals, the brain may have difficulty processing or organizing this sensory information, leading to an overreaction, underreaction, or difficulty filtering it.
What does a person with sensory processing issues experience?
Types of Sensory Issues:
Sensory issues can affect any of the senses and often fall into two categories: sensory over-responsivity (hypersensitivity) and sensory under-responsivity (hyposensitivity). Here’s a breakdown:
1. Sensory Over-Responsivity (Hypersensitivity)
- Description: Individuals who are hypersensitive to sensory stimuli may become overwhelmed or distressed by sensations that others might find mild or tolerable. For example, loud sounds, bright lights, or certain textures can cause significant discomfort or anxiety.
- Examples:
- Sensitivity to certain fabrics or clothing tags (e.g., itchy sensations).
- Overreaction to loud noises (e.g., covering ears or becoming upset with sounds like sirens or vacuum cleaners).
- Sensitivity to bright lights, which may cause discomfort or even pain.
- Becoming easily overwhelmed in crowded places due to excessive visual or auditory stimulation.
2. Sensory Under-Responsivity (Hyposensitivity)
- Description: Individuals with sensory under-responsivity may not respond to sensory stimuli in a typical way. They might seek out additional sensory input because their brain doesn’t register it adequately.
- Examples:
- Lacking response to loud noises or not noticing when they are in a noisy environment.
- Seeking intense physical sensations, like jumping or crashing into things, because they don’t feel the normal level of input.
- Not reacting to pain in the way others do (e.g., not noticing a scrape or bump).
3. Sensory Seeking
- Description: This involves actively seeking out sensory experiences, often in ways that may seem unusual or excessive to others. People who are sensory seekers might engage in activities that provide more input (e.g., movement, tactile sensations, or sound) to meet their sensory needs.
- Examples:
- Constantly moving or fidgeting, such as rocking or spinning.
- Chewing on objects or hands, even when it’s inappropriate.
- Enjoying strong smells, tastes, or visual stimulation.
- Engaging in high-energy activities like jumping, climbing, or touching everything.
4. Sensory Avoiding
- Description: This refers to actively avoiding or becoming distressed by sensory input. Sensory avoiders are likely to try to reduce or escape from overwhelming sensory experiences.
- Examples:
- Avoiding crowded areas because of the noise and visual input.
- Disliking certain textures of food or clothing and refusing to wear them.
- Covering ears to block out loud noises, like sirens, or leaving rooms with harsh lighting.
Common Sensory Issues in Various Conditions:
Sensory issues are often seen in individuals with conditions such as:
- Autism Spectrum Disorder (ASD): Many individuals on the autism spectrum experience sensory sensitivities or seek out excessive sensory input.
- Attention Deficit Hyperactivity Disorder (ADHD): People with ADHD may struggle to filter out distractions or seek out sensory stimulation to help them focus.
- Sensory Processing Disorder (SPD): SPD is a condition where the brain has difficulty processing and responding to sensory input in a typical way. It can manifest as either hypersensitivity or hyposensitivity to various sensory stimuli.
- Anxiety Disorders: People with anxiety may have heightened sensitivities to sensory stimuli due to their nervous system being more reactive.
Signs of Sensory Issues:
Signs that a person may have sensory processing issues include:
- Avoidance behaviors: Avoiding certain textures, foods, sounds, or environments.
- Emotional responses: Overreacting emotionally to sensory stimuli (e.g., crying, screaming, or becoming anxious).
- Difficulty focusing: Trouble focusing on tasks due to being distracted by sensory stimuli.
- Impulsive behavior: Seeking out sensory input in an intense way, such as excessive movement, touching objects, or making loud noises.
