How do I know if I have Sensory Processing Disorder?

Sensory Processing Disorder (SPD) is a condition where the brain has difficulty receiving and responding to information that comes in through the senses. You may suspect Sensory Processing Disorder if you experience chronic, overwhelming reactions to everyday stimuli—such as loud noises, specific textures, or bright lights—that significantly interfere with your daily functioning, social interactions, or work performance.

What are the common signs of Sensory Processing Disorder?

People with Sensory Processing Disorder often describe their nervous system as being "stuck" in a state of high alert or, conversely, being under-responsive. While everyone has unique sensory preferences, Sensory Processing Disorder is characterized by the intensity and disruptive nature of these reactions. Common patterns include:

• Sensory Over-responsivity: Feeling physically pained by tags on clothing, loud environments, or specific food textures.


• Sensory Under-responsivity: A high threshold for pain or a constant need for deep pressure, movement, or "fidgeting" to feel grounded.


• Motor Coordination Issues: Difficulties with balance, clumsiness, or poor spatial awareness.

How is Sensory Processing Disorder diagnosed?

There is no single blood test or brain scan to diagnose Sensory Processing Disorder. Instead, diagnosis is typically clinical, performed by an occupational therapist (OT) or a developmental pediatrician. They use standardized tools like the Sensory Profile or the Sensory Processing Measure to map your responses against normative data. It is important to note that Sensory Processing Disorder is often comorbid with other conditions, such as ADHD or Autism Spectrum Disorder, which a specialist will help differentiate.

When should you consult a doctor?

If your sensory sensitivities are causing you significant emotional distress, social isolation, or preventing you from completing daily tasks, it is time to speak with a healthcare provider. When you make an appointment, explicitly state: "I am concerned that my nervous system is not processing sensory input correctly, and I would like a referral to an occupational therapist who specializes in sensory integration."

Red flags and self-advocacy

If you feel your concerns are being dismissed, seek a second opinion from a specialist who understands neurodivergence. Seek urgent medical evaluation if sensory overload leads to self-harm, total withdrawal from basic self-care, or severe panic attacks. You are the expert on your own body; if your quality of life is impacted, your concerns are valid.
