Yes, we are watching a new psychiatric disorder evolve in real time: "sluggish cognitive tempo," characterized by people who are "daydreamy, mentally foggy, easily confused, and staring frequently."
According to Alan Schwarz in the New York Times:
"Experts pushing for more research into sluggish cognitive tempo say it
is gaining momentum toward recognition as a legitimate disorder — and,
as such, a candidate for pharmacological treatment. Some of the
condition’s researchers have helped Eli Lilly investigate how its
flagship A.D.H.D. drug might treat it."
"The Journal of Abnormal Child Psychology devoted 136 pages of its
January issue to papers describing the illness, with the lead paper
claiming that the question of its existence 'seems to be laid to rest as
of this issue.' The psychologist Russell Barkley of the Medical
University of South Carolina, for 30 years one of A.D.H.D.’s most
influential and visible proponents, has claimed in research papers and lectures that sluggish cognitive tempo 'has become the new attention disorder.'”
