The subsequent development of higher-order self-regulation is jeopardized and the formation of internal models is affected. Consequently, the "templates" in the mind that drive organized behavior in relationships may be impacted. The potential for "re-regulation" (modulation of emotional responses to within the normal range) in the presence of "corrective" experiences (normative caregiving) seems possible. Diagnosis
RAD is one of the least researched and most poorly understood disorders in the DSM. There is little systematic epidemiologic information on RAD, its course is not well established and it appears difficult to diagnose accurately. There is a lack of clarity about the presentation of attachment disorders over the age of five years and difficulty in distinguishing between aspects of attachment disorders, disorganized attachment or the consequences of maltreatment.According to the American Academy of Child and Adolescent Psychiatry (AACAP), children who exhibit signs of reactive attachment disorder need a comprehensive psychiatric assessment and individualized treatment plan. The signs or symptoms of RAD may also be found in other psychiatric disorders and AACAP advises against giving a child this label or diagnosis without a comprehensive evaluation. Their practice parameter states that the assessment of reactive attachment disorder requires evidence directly obtained from serial observations of the child interacting with his or her primary caregivers and history (as available) of the childs patterns of attachment behavior with these caregivers. It also requires observations of the childs behavior with unfamiliar adults and a comprehensive history of the childs early caregiving environment including, for example, pediatricians, teachers, or caseworkers.
Improvement of diagnostic tools, increasing disease awareness, and digitised patient registration with facilitation of case-findings, along with improved survival, likely contributed to the rising prevalence rates. The disease has been described worldwide, though North America and Northern Europe have shown the highest incidence and prevalence rates. Whether a true variation in disease prevalence exists among populations of different geographical areas and of different ethnicity or if this is a consequence of a difference in study quality is unknown. PBC is more common in women, with a female:male ratio of at least 9:1. The peak incidence of PBC is in the fifth decade of life. In some areas of the US and UK, the prevalence is estimated to be as high as one in 4,000. This is much more common than in South America or Africa, which may be due to better recognition in the US and UK. First-degree relatives may have as much as a 500 times increase in prevalence, but if this risk is greater in the same-generation relatives or the one that follows is debated. PBC is considered a prime example of the female preponderance in autoimmunity with a female to male ratio of up to 9:1, confirmed by large cohort studies, although some recent data, using administrative registries, suggest an increasing male prevalence.
