The different patterns of juvenile arthritis may require different treatment approaches and have different outcomes. Regardless of what pattern of juvenile arthritis develops, an affected person will have painful, inflamed joints. This may result in stiffness (particularly in the morning), limping and reluctance to engage in certain activities.
Causes and Risk Factors
The cause of juvenile arthritis is not known. There are some indications that certain types of childhood arthritis or children who develop particular complications from the condition have genetic origins. Although some genetic markers may be associated with an increased chance of developing arthritis, these conditions are not regarded as hereditary and rarely affect more than one family member. Some evidence suggests that there could be infectious triggers in a genetically predisposed child.
