Post #2 Sensory Processing Disorder
At least one in twenty people in the general population may be affected by SPD. Gifted children (savant) or children with ADHD, Autism, or fragile x syndrome are at a much higher risk. Sensory Processing Disorder has strange symptoms that do not really relate to any other disorders or can be explained. Through research heredity may be a possible cause. All that researchers know so far is that the sympathetic and parasympathetic nervous systems are not functioning normally. This is important because these symptoms affect important functions that occur in the human body such as with the parasympathetic it controls urination, sexual arousal, and rest, and feeding.
