Excessive activity is the most visible sign of AD/HD. The hyperactive toddler/preschooler is generally described as "always on the go" or "motor driven." With age activity levels may diminish. By adolescence and adulthood the over-activity may appear as restless, fidgety behavior (American Psychiatric Association, 1994).
Symptoms of hyperactivity as listed in the DSM-IV are:
- Often fidgets with hands or feet or squirms in seat.
- Often leaves seat in classroom or in other situations in which remaining seated is expected.
- Often runs about or climbs excessively in situations that are inappropriate (in adolescents or adults, may be limited to subjective feelings of restlessness).
- Often has difficulty playing or engaging in leisure activities quietly.
- Is often "on the go" or acts as if ˇĄdriven by a motor".
- Often talks excessively.
