This article's main objective is to seek out similarities and/or differences between juvenile (child and adolescent) obsessive-compulsive disorder and adult forms of the disease. It states three competing hypotheses on the relationship between juvenile and adult OCD: 1. juvenile and adult OCD are continuous, meaning the same, disorders; 2. juvenile and adult OCD are discontinuous, different, disorders; and 3. juvenile and adult OCD are continuous but the juvenile disorder is more severe. A systematic review of studies done on both disorders was reviewed in order to make a conclusion in this article. Things that were considered include, age at onset, gender distribution, symptom phenomenology, psychiatric comorbidity, neurological and perinatal history, family psychiatric history, cognitive and neuropsychological profiles, treatment, and outcome. The expected to find that if the two disorders were part of the same disorder, then they would find similar correlates between the two and if they were different they would expect to find vast differences between the two of them and also if juvenile OCD is a more severe form of adult OCD, that there would be differences there as well.
             The author went through all the results of articles on juvenile OCD and found there to be 43 original articles. He grouped them based on their primary focus. He then went on to list the findings he found in regard to the cases he studied and came up with a lengthy conclusion on the matter. His review identified important similarities and differences between juvenile and adult OCD. He found that children tend to have less insight regarding their illness. Another similarity between the two is the treatment response and found that the earlier the onset of OCD, the poorer the response to the treatments, however, it was unclear the extent to which age at onset affects the outcome. They found that there wasn't enough scientific information on this subject to warrant ...
