Document Summary

Following the worldwide influenza epidemic from 1917 to 1926. "brain injured child syndrome: 1940s-1950s: minimal brain damage and minimal brain dysfunction. Core characteristics: key symptoms fall under two well-documented categories. Inattention: hyperactivity-impulsivity, using these dimensions to define adhd oversimplifies the disorder, attention and impulse control are closely connected developmentally. Inability to sustain attention, particularly for repetitive, structured, and less-enjoyable tasks: deficits may be seen in one or more types of attention, attentional capacity, selective attention, distractibility, sustained attention/vigilance (a core feature) Inability to voluntarily inhibit dominant or ongoing behaviour: hyperactive behaviours include, fidgeting and difficulty staying seated, moving, running, touching everything in sight, excessive talking, and pencil tapping, excessively energetic, intense, inappropriate, and not goal-directed. Adhd presentation types: predominantly inattentive presentation (adhd-pi) Limitations of dsm criteria for adhd: developmentally insensitive, categorical view of adhd, dsm criteria shape our understanding of adhd, dsm criteria are also shaped by, and in some instances lag behind, new research findings.
