Abstract
It is often said that the "gold standard" for pain assessment in both children and adults is verbal report. This means that the individual is best at describing his or her pain experience. This however does not take into account individuals who lack the ability to communicate their feelings including those with cognitive immaturity such as infants and very young children, people with cognitive impairment and adults with dementia. This is even complicated by the fact that children who experience the most pain are those who are least able to verbally describe it; those with greater physical and cognitive disability. This paper reviews past and current beliefs on the experience and expression of pain in children with cognitive impairment and how parents can be used as useful tools in diagnosing their pain.
