Sluggish cognitive tempo (SCT) is the term for a syndrome that may comprise a novel and distinct attention disorder from ADHD. Symptoms of it include dreaminess, mental fogginess, hypoactivity, sluggishness, staring frequently, inconsistent alertness and a slow working speed.
SCT has been a subject of controversy for decades and debate about its nature still continues. But it is clear now that this set of symptoms is important because it significantly adds to impairment in ADHD and independently predicts a low quality of life.[1][2] Some have encouraged the use of the term concentration deficit disorder (CDD) for SCT because it may be more appropriate and less derogatory.[3]
Originally, SCT was thought to be entirely limited to about 1/3 of the inattentive subtype of ADHD[4] and being apparently incompatible with hyperactivity. But new studies showed that it is also seen in some with the other two ADHD subtypes – and in individuals without ADHD as well. Therefore, some psychologists and psychiatrists think it should be its own mental disorder. Others dismiss it altogether or believe it is a separate symptom group within ADHD (like Hyperactivity, Impulsivity or Inattention). It even may be useful as a transdiagnostic concept that is shared among different mental disorders (like emotional dysregulation, for example, which cuts across many disorders).[5]
