Any neuroscientific articles on ADHD-PI/Sluggish Cognitive Tempo?

I am realizing that these "subtypes" of ADHD more cleanly overlap with my symptoms than "traditional" ADHD. I have found some good behavioral descriptions, but I am curious to learn more about the underlying neural mechanisms.

SCT is not really a subtype of ADHD but it is associateed with inattentive subtype ADHD. Go to pubmed.org and search the phrase "sluggish cognitive tempo". There is lots of info on ADHD with SCT there.

I did this and found 15 articles. Good suggestion from Speedo

You can also go to The National Resource Center on AD/HD:
http://www.help4adhd.org/

There is a section where you can email questions and someone will get back to you. Tested it several years ago on a technical question and got a good technical answer back. Might be worth a try.

If you are a college student, you might hit the library. Colleges usually have some good resources such as Psychlit that are not available on the net.


The problem is that there is not a lot known about SCT and especially with the neurological basis for it.

Barkley once stated in a workshop that, at that time, the ratio of impulsive hyperactive type to inattentive type was about 100 to 1 .

Thankfully this is beginning to change but I suspect you will not yet find much available.

I think some would beg to differ on that, even if it goes against the grain of current scientific research.

I myself still tend to think that SCT is at the end of the ADHD-PI spectrum.

And you may well be right. The matter is not settled yet however the weight of the research is leaning in the direction of separate disorder.

If the treatment is the same as for ADHD then a different diagnosis is not all that useful. If the treatment needs to be different for SCT then a separate diagnosis is vital.

Good discussion.

Barkley and Adele Diamond have both suggested that inattentive ADHD may actually be a fundamentally different "disorder" from ADHD-H altogether.
http://www.pubmedcentral.nih.gov/art...?artid=1474811

I like her characterization of it as "dysexecutive syndrome" as my main issues with inattentiveness are my screwed up executive functions. I see the low energy that other people report as a dysthemic comorbidity, which apparently is quite common with inattentive only ADHD. SCT could well be inattentive only ADHD with a dysthemic comorbidity. Anyway, this is obviously conjecture on my part, but if I was a researcher in the field I would look into it.

Re: Any neuroscientific articles on ADHD-PI/Sluggish Cognitive Tempo?

Following up on my previous post, if Diamond's hypothesis is correct, then hyperactive ADHD should be renamed inhibition deficit disorder and inattentive ADHD should be renamed working memory deficit disorder. They have overlaps in symptoms, but the underlying core deficits are different and should be treated with different medications with the former being more likely to respond to methylphenidate and the latter to amphetamines.
