This can be referred to as either dysfunction in sensory integration (DSI) or sensory processing disorder (SPD). Sensory processing disorder is used more commonly in the context of research, while a clinician will often use the term sensory integration dysfunction.
Call POTS on the phone to talk about if sensory integration-based evaluation might be useful. Speaking to a therapist certified in SI can help you make a decision if an evaluation might be right for your child.
There may be a variety of causes, such as genetics, premature birth, birth trauma, exposure to toxins, etc. Currently, there is no “official” cause known.
With occupational therapy, it is possible that the problems can be minimized. The nervous system can be changed, and the ability to process sensation can be improved. Biological research has shown that with therapy, sensory processing dysfunction with daily life activities can be minimized greatly.
It has not been found that these challenges go away with time. They can appear to be minimized due to the greater flexibility adults usually enjoy in choosing daily activities in comparison to children. Adults can also receive therapy for sensory integration.
