SynopsisThe present study compared families of patients with anorexia nervosa with families of non-anorexic adolescent daughters of a similar social class. All anorexics and adolescent comparison girls and their parents were studied using a variety of psychometric measures. Body size estimation and physical anhedonia were also measured. Family characteristics were assessed using the Family Assessment Measure (FAM). Contrary to the hypotheses, no abnormalities were found in terms of parental attitudes to weight control or dieting. The mothers of anorexics displayed no increase in psychopathology on any of the measures. The fathers scored very similarly to controls but with higher degrees of conscientiousness. Neither fathers nor mothers displayed abnormalities of their own body size estimates or body satisfaction. On the FAM the anorexic families reported an increased pathology on several sub-scales. It is not possible to say whether these disturbances are part of the pathogenesis or are sequelae to the illness.
Abnormal circadian rhythms have been associated with affective disorders. A review of this rapidly expanding area of investigation shows that while a clear causal relationship has not yet been proven, a knowledge of the circadian system and its dysfunction can help in understanding unipolar and bipolar depression. Evidence suggests that existing therapies such as lithium and antidepressants act upon the circadian system. Better identification of individuals at risk for affective disorders and the development of new preventive and therapeutic interventions may result from further study of circadian dysfunction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
