Step 1
Evaluate a contemporary study on Anorexia Nervosa.
Answer
Anorexia Nervosa is a serious eating disorder characterized by an obsession with weight loss and food intake regulation.
One significant study is by Kaye (2011), which found that increased dopamine levels in individuals with anorexia led to heightened anxiety. This suggests that rather than feeling pleasure from food, those with anorexia may associate eating with anxiety and stress. Moreover, it indicates a potential genetic linkage as the study highlights how dopamine levels might not only influence eating behaviors but also be due to genetic predispositions.
This contemporary perspective shifts the understanding from merely biological aspects to also consider psychological factors, opening avenues for integrative treatment approaches. However, this approach raises questions about the reliability of biological versus environmental factors in the onset of anorexia.
Additionally, Babak et al. (2014) explored pharmacological interventions, finding that medication aimed at reducing anxiety could allow individuals to regain appetite. Yet, it is crucial to acknowledge that medication alone may not resolve underlying cognitive frameworks that lead to anorexia. It often requires a comprehensive treatment strategy that addresses psychological and social dynamics alongside biological treatments.
Step 2
Evaluate a contemporary study on Unipolar Depression.
Answer
Unipolar Depression is a mood disorder marked by persistent feelings of sadness and loss of interest.
A pivotal study by Drevet et al. (1999) demonstrated reduced serotonin receptor-binding potential in unmedicated depressed patients, suggesting a direct correlation between serotonin levels and mood regulation. This study implies that the serotonin system is fundamental in understanding the biological basis of depression.
Furthermore, research has shown that anti-depressants that increase monoamine levels can alleviate symptoms, pointing to the monamine hypothesis as a guiding principle in the treatment of depression. Despite its significance, critiques arise concerning the long-term efficacy of such treatments and the ongoing challenge of individual differences in response to medication.
Additionally, it is essential to consider the ethical implications of relying solely on pharmacological treatments when addressing unipolar depression, as psychological and social factors may heavily influence the disorder's course.
