sluggish cognitive tempo
A constellation of symptoms* described as daydreamy, mentally foggy, easily confused, with periodic staring episodes. Affected individuals are typically hypoactive, lethargic, slow, and sleepy.
*SCT was proposed as a condition a sui generis to be included in the 5th edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorder (DSM-5), but was not accepted in the final version published in 2013.
SCT describes what some authors regard as a large homogeneous subgroup of individuals diagnosed as ADHD predominantly inattentive–ADHD-PI. In contrast to those with ADHD-PI, who are hyperactive, extroverted, obtrusive, and risk takers, those with SCT have slow mental processing and reaction times, are introspective, daydream, and feel as if they’re in the fog. Compared to those with ADHD, SCT children have far lower rates of oppositional defiant disorder and conduct disorder, but a greater risk of anxiety, depression, and social withdrawal.
