Which is a true statement regarding depressive disorders?

Choice A reason: Stating that depressive disorders are the 4th leading cause of years lost due to disability is factually inaccurate. According to the World Health Organization (WHO) and the Global Burden of Disease data, major depressive disorder is 1 of the leading contributors to disability worldwide and is ranked among the top causes of years lived with disability (YLD), not merely the 4th. Some data rank it as the single leading cause of disability globally when measured in YLD. Presenting it as the 4th leading cause misrepresents its global public health significance and would therefore not constitute a true statement for nursing education purposes. Choice B reason: The monoamine hypothesis of depression, which implicates dysregulation of the neurotransmitters norepinephrine, dopamine, and serotonin in the pathophysiology of depressive disorders, is a well-established and widely accepted neuroscientific framework. Evidence supporting this hypothesis comes from multiple sources, including the clinical efficacy of pharmacological agents that enhance monoaminergic neurotransmission, such as SSRIs, SNRIs, MAOIs, and tricyclic antidepressants, as well as neurobiological research demonstrating altered monoamine receptor density and function in individuals with depression. While the monoamine hypothesis has been refined and expanded to include neuroendocrine, neuroplasticity, and inflammatory mechanisms, the fundamental role of these 3 neurotransmitters remains an established and clinically relevant true statement. Choice C reason: The assertion that depression in older adults is easier to diagnose is factually incorrect. Depression in geriatric populations is notoriously difficult to diagnose for multiple reasons: older adults often present with atypical symptoms such as somatic complaints, cognitive impairment (depressive pseudodementia), anhedonia rather than overt sadness, and medical comorbidities that mask or mimic depressive features. Additionally, both patients and providers may attribute depressive symptoms to normal aging. Depression in older adults is frequently underdiagnosed and undertreated due to these diagnostic challenges, making this statement demonstrably false and clinically misleading. Choice D reason: The assertion that depressive disorders are more prevalent in males than females contradicts robust epidemiological evidence. Consistently across cross-cultural, national, and international studies, major depressive disorder and dysthymic disorder are approximately 2 times more prevalent in females than in males throughout the lifespan, particularly from adolescence through menopause. Hormonal factors, including estrogen and progesterone fluctuations, as well as psychosocial contributors such as higher rates of trauma exposure and socioeconomic disadvantage, are implicated in the higher female prevalence. Stating that depression is more prevalent in males is factually inaccurate and inconsistent with global epidemiological data.
