longitudinal research showed that there is an increase in chance that a young adult female would develop bulimia due to their current psychological pressure and as the person ages and matures, their emotional problems change or are resolved and then the symptoms decline.Several types of scales are currently used – (a) self-report questionnaires –EDI-3, BSQ, TFEQ, MAC, BULIT-R, QEWP-R, EDE-Q, EAT, NEQ – and other; (b) semi-structured interviews – SCID-I, EDE – and other; (c) clinical interviews unstructured or observer-based rating scales- Morgan Russel scale The majority of the scales used were described and used in adult populations. From all the scales evaluated and analyzed, only three are described at the child population – it is EAT-26 (children above 16 years), EDI-3 (children above 13 years), and ANSOCQ (children above 13 years). It is essential to develop specific scales for people under 18 years of age, given the increasing incidence of ED among children and the need for early detection and appropriate intervention. Moreover, the urgent need for accurate scales and telemedicine testing and diagnosis tools are of high importance during the COVID-19 pandemic (Leti, Garner & al., 2020). Differential diagnoses
There are multiple medical conditions which may be misdiagnosed as a primary psychiatric disorder, complicating or delaying treatment. These may have a synergistic effect on conditions which mimic an eating disorder or on a properly diagnosed eating disorder. Lyme disease is known as the "great imitator", as it may present as a variety of psychiatric or neurological disorders including anorexia nervosa.
For Ontario, Canada patients who received specialized inpatient care for an eating disorder both out of country and in province, annual total healthcare costs were about $11 million before 2007 and $6.5 million in the years afterwards. For those treated out of country alone, costs were about $5 million before 2007 and $2 million in the years afterwards. Evolutionary perspective
In recent years. evolutionary psychiatry as an emerging scientific discipline has been studying mental disorders from an evolutionary perspective. If eating disorders have evolutionary functions or if they are new modern "lifestyle" problems is still debated. See also
