sensory integration dysfunction
A neurological condition where the brain has difficulty processing and responding to sensory information from the environment and body.
Full Definition
Sensory integration dysfunction (also called sensory processing disorder) occurs when the nervous system receives sensory messages but does not organize them into appropriate behavioral responses. Children with this condition may be oversensitive or undersensitive to sensory stimuli, affecting their ability to participate in daily activities. Symptoms can include difficulty with balance and coordination, oversensitivity to touch or sound, or seeking excessive sensory input. Occupational therapists use specialized assessment tools and provide intervention through sensory integration therapy, environmental modifications, and sensory diets. The condition often co-occurs with autism spectrum disorders and attention deficit hyperactivity disorder.
Usage
Usage note: Note that 'sensory processing disorder' is increasingly preferred in current literature over 'sensory integration dysfunction'.
