Questions about so called SCT?

According to Dr. Barkley, half the people who have ADHD have SCT, and, half the people who have SCT have ADHD.

If all people diagnosed with ADHD-Combined and ADHD-Predominantly Hyperactive/Impulsive have must have a certain number of hyperactive symptoms to meet the diagnostic criteria, and people who have SCT do not have any hyperactive symptoms.

Does that mean only people who have ADHD-Predominately Inattentive could possibly have so called SCT?

(I have more questions, but I will start with this question)

This assumption is not necessarily accurate. Some people who have SCT symptoms may also have hyperactive-impulsive symptoms.

For example, they may be fidgety (ADHD symptom) and also have trouble regulating alertness ("SCT" symptom), they may frequently interrupt other people (ADHD symptom) and also stare into space a lot ("SCT" symptom), etc.

There are some proposed "SCT" symptoms that would be difficult to show at the same time as ADHD symptoms, like hypoactivity and hyperactivity. I would guess that these particular symptoms would not coexist -- unless the person swings from one to the other without "normal" activity levels in-between. (Though I don't think this really fits the models of either ADHD or SCT -- it's more like bipolar disorder.) But other sets of symptoms, like the ones I mentioned above, are not mutually exclusive, and can coexist.

The criteria for "SCT" are not yet well established, and the level and nature of overlap with ADHD (of all presentations) remains unclear.

I only have one of the five hyperactive symptoms, but I have all four of the
impulsive symptoms.

I have all nine of the inattentive symptoms. I don't have an official diagnosis
but I would guess I'd be considered combined presentation.


There seems to be sixteen symptoms listed for SCT. I have at least half of the
symptoms on that list ... but I don't know how many I had before I developed
Fibromyalgia and a lot of the symptoms overlap between FM and SCT.


Found this on Wiki =
Quote:
Originally, SCT was thought to be restricted to about 1/3 of the inattentive subtype of ADHD and being apparently incompatible with hyperactivity.

But new research showed that SCT is also seen in some with the combined or hyperactive-impulsive subtype – and in individuals who do not have ADHD at all.

Re: Questions about so called SCT?

mild, you are once again demonstrating you do not understand the difference between inclusion versus exclusion in regards to diagnostic criteria.

The multi-point description of SCT is inclusive, but not exclusive.


Cheers,
Ian

Thanks.

I meant to ask you what you meant, and I forgot.

What do you mean?

Re: Questions about so called SCT?

The description of SCT includes a suggested list of criteria.

But it does not exclude anything.

For example, a person with SCT could be, at times, hyperactive.

Which is why there is no way to know which 50% of those with ADHD might have it.

Inclusion rules in, but it does not rule out.


Cheers,
Ian

Re: Questions about so called SCT?

If SCT (or ADD) is the second attention disorder.

What is the first attention disorder?

If you're referring to Barkley's claim, he considers ADHD (in any of its presentations, with at least some symptoms of hyperactivity or impulsivity) to be one kind of attention disorder, and "SCT"/"CDD" to be another.

He seems to believe that ADHD is primarily a problem of executive function and impulse control, whereas that "SCT"/"CDD" is primarily a problem of regulation of alertness/arousal and sustained attention.

(Some people might argue that sustaining attention is an executive function, and/or that ADHD is also related to regulation of alertness/arousal and sustained attention. TygerSan made the point in another thread that the roles of impulse control vs. attentional processes -- and different types of attentional processes -- have been hotly debated since people started thinking about these things as disorders.)

Is SCT (or ADD) and CDD the same thing?

Re: Questions about so called SCT?

"CDD" ("Concentration Deficit Disorder") is the name Barkley prefers to use for what other researchers have been calling "SCT" ("Sluggish Cognitive Tempo"). So yes, "CDD" = "SCT".

Re: Questions about so called SCT?

It may be wild and wacky. But I sometimes think that SCT could be a separate symptom cluster, and in some cases be a reaction to ADHD

In psycho babble dissociation(sct) to emotional trauma (adhd) type relationship

(2:08) In this video Dr. Barkley says, “ADD-without H was found to involve...”

Quote:
-Slow and inaccurate information processing.

-Daydreamy, staring, easily confused, mental fogginess.

-Hypoactivity, sluggish movement, lethargy

-Social withdrawn, shy, anxious
