Sluggish Cognitive Tempo/Concentration Deficit Disorder
Abstract
Abstract Sluggish cognitive tempo (SCT), or concentration deficit disorder (CDD), comprises excessive daydreaming, staring, mental fogginess and confusion, drowsiness, lethargy, sluggishness, and hypoactivity, among other symptoms. This article summarizes the findings on CDD/SCT and its relationship to attention deficit hyperactivity disorder (ADHD). The cognitive dysfunction underlying CDD remains to be clarified. But its symptoms comprise a two-dimensional structure that is separate from those in ADHD. CDD is reliably associated with social withdrawal and is more strongly related to internalizing than to externalizing psychopathology, in contrast to ADHD. Both ADHD and CDD are impairing, but ADHD is more so. Little evidence exists on the etiologies of CDD or on response to treatments. More research is needed on all facets of CDD before its status as a new disorder can be confirmed.

The lack of a strong and consistent association between CDS and slowed processing speed was one reason for changing the terminology from sluggish cognitive tempo to CDS, along with the derogatory connotation of "sluggish."
“This lack of strong and consistent association was one impetus for changing the terminology from sluggish cognitive tempo to CDS, in addition to the derogatory connotation carried by the word “sluggish” [1, 41, 42].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
