Sensory Processing Disorder (SPD) is a condition where the brain has difficulty receiving and responding to sensory information. People with SPD may find everyday sensations, like sounds, textures, or lights, overwhelming or confusing. For example, a child might become upset by the feel of certain fabrics or the noise of a crowded room, making it hard for them to focus or enjoy activities. This disorder can affect anyone, but it is often seen in children, sometimes alongside conditions like autism or ADHD. Treatment may include therapies that help individuals learn to manage their sensory experiences, allowing them to engage more comfortably with the world around them.
