The mean Sensory Identification Score for children with ADHD and for the control group was 3.76 and 4.46, respectively. The mean for Sensory Threshold Score for the ADHD subjects and for the control group was 6.4 and 9.75, respectively. The researchers said their results do not seem to be a result of olfactory task difficulty and were not influenced by age, gender, or MSS.
Recent research has also identified rare genetic variations in children with ADHD that may help identify children at risk for developing the disorder. Read more about those findings in Psychiatric News, here.
