Sensory Processing Disorder (SPD) is a condition affecting at least one in twenty children who experience sensations in taste, touch, sound, sight, smell, movement, and body awareness in a vastly different manner from how other children their ages do. What may be typical activities for most kids are a daily struggle that may result in social, emotional, or academic problems. Dr. Lucy Jane Miller, the best-known SPD researcher in the world, brings together a lifetime of study to teach parents and others the signs and symptoms of SPD and its four major subtypes; ways the disorder is diagnosed and treated; sensory strategies for living with the condition; and methods to help SPD kids thrive.
