The etiology of<unk>  has many explanations which differ from case to case. Many<unk> cal disorders in children involve genetic and physiological mechanisms, though there are still many without any physical grounds. It is absolutely imperative that multiple sources of data be gathered. Diagnosing the<unk>  of children is daunting. It is influenced by development and contest, in addition to the traditional sources. Interviews with parents about school, etc., are inadequate. Either reports from teachers or direct observation by the professional are critical. (author, Robert B. Bloom, Ph.D.) The disorders with physical or biological mechanisms are easier to diagnose in children and are often diagnosed earlier in childhood. However, there are some disorders, no matter the mechanisms, that are not identified until adulthood. There is also reason to believe that there is co-morbidity of disorders, in that if one disorder is present, there is often another.
