|Sluggish Cognitive Tempo "Daydreamy and Lethargic"|
Barkley reports that people with SCT differ from people with all types of ADHD in that they are more "day-dreamy, mentally confused, lethargic and much more markedly hypo-active". Some folks consider Russell Barkley to be the U.S. authority on ADHD. Barkley is one of the first ADHD experts who suggested that ADHD Inattentive might not be ADHD at all. He has, in past reports, speculated that people with ADHD Inattentive (ADHD-PI) are really people who should be diagnosed with Sluggish Cognitive tempo.
I have disagreed with that assessment as both my son and I are inattentive but normally active. Not hypo-active or hyperactive and I have argued that there are a subset of people with ADHD Inattentive (ADHD-I)that are not sluggish or mentally confused though they are day-dreamy.
This new study, I think, is Barkley's attempt to sort this all out. The findings are interesting in that it appears that having SCT symptoms means that you will be less able to resolve problems and organize your life and in turn you will tend to do worse at school, at work and at home.
The only area where people with ADHD without SCT fared worse than their SCT cousins was in the area of driving. It appears, from Barkley's study, that people with just ADHD symptoms had poorer driving records than people with SCT and ADHD symptoms or people with just SCT symptoms.
I had thought that Russell Barkley had abandoned study of the ADHD Inattentive and Sluggish Cogntive Tempo subgroup of patients all together. He seemed to be focused on his model of ADHD as a disease of Emotional dysregulation and his descriptions of ADHD did not resonate with me as it failed to describe people with ADHD Inattentive type. I am thrilled to see that his studies are still trying to work out the subtleties of SCT. This condition is terribly disabling and deserves more attention than it has received in the past.
Many more studies need to be done to determine how the symptoms of ADHD-PI differs from Combined type ADHD and from SCT but I am happy to see that Russell Barkley is still attempting to sort out this wide array of ADHD Executive Function disabilities.
