RESEARCH
The validity of Sensory
Processing Disorder has been questioned by the medical community and many feel
that there isn’t enough empirical data to indicate that SPD is a singular
diagnosis. This is largely due to the
co-existence of other diagnoses in most cases (ie. Autism, ADHD). Many in the medical community feel that a
diagnosis of SPD misses the true underlying problem and can delay
treatment. The updated DSM-V that will
be published in May once again failed to include SPD as a diagnosis, citing
that more research is needed first.
Below are various sources
that I have found helpful:
http://www.spdfoundation.net/pdf/E3958931.pdf :
Similarities exist in early health records of SPD children. Jaundice was of high prevalence, along with
allergies, prematurity and birth complications.
http://www.spdfoundation.net/pdf/Schaaf_et_al_parasympathetic_functions_in_children_with_spd.pdf:
Children with SPD have lower than normal
PSNS activity (parasympathetic nervous system).
The PSNS helps to regulate reactivity.
http://www.spdfoundation.net/pdf/davies_gavin.pdf This study researched brain activity through
EEGs showing that children with SPD demonstrated a lower than normal ability to
distinguish and process stimuli.
