"Hyepractivity" is a common misspelling of the word "hyperactivity."
Attention Deficit Hyperactivity Disorder, often called ADD or ADHD, is a diagnostic label that we give to children and adults who have significant problems in four main areas of their lives:
+ Trouble staying focused to a task, trouble paying attention.
+ Being impulsive, not thinking before doing.
+ Being "hyepractive" (sic) or "hyperactive."
+ Being easily bored with work that is repetitive, or difficult.
Hyperactivity is defined as "Excessive, non-goal directed, motor activity."
There are times when we all have to move quickly, or have to work very hard to accomplish a task. During these time we might display "excessive... motor activity." However, because we are working on a task, it is "goal directed" activity. In "hyperactivity" we see "excessive... motor activity" that is not goal directed. Individuals seem to go from one thing to another without ever finishing the first task, or the second task, or anything.
