When looking at behavior, there are close similarities displayed with both children who have attention difficulties (ADD/ ADHD) and sensory processing disorder (SPD). Co-morbid diagnoses may include Autism, Developmental Delays, and Learning Disabilities. Common characteristics for children with both sensory seeking SPD and ADHD (hyperactive/impulsive type) are as follows: impulsivity, excessive activity, disorganization, impatience and poor self-control.
However, more specifically, children who have SPD tend to be more in control of stopping impulsive behaviors. They may crave activity relating to a specific sensory system, may become more organized after receiving proper sensory input and may be more patient while waiting if give proper sensory input. They commonly poke/pull/touch others without proper sensory input.
Those who have ADHD (hyperactive/impulsive type), tend to continue impulsive behaviors, be disorganized and have difficulty waiting-even with sensory input. They tend to crave activity not related to a specific sensory system. They often talk a lot, impulsively interrupt, and have difficulty waiting a turn during a conversation.
