Abstract
Dorothy Herson examines the idea that mood disorders, including depression and bipolar disorder, might be better understood as conditions of energy dysregulation and motor activity rather than simply disorders of mood. Herson suggests that traditional perspectives, which largely emphasize mood symptoms, may not fully capture the significance of energy dynamics in these disorders. The paper underscores the importance of developing methods to actively monitor both subjective energy levels and objective motor behaviors, which could help distinguish different subtypes of mood disorders, predict their progression, and improve treatment outcomes. Drawing from personal experiences with Type 1 bipolar disorder, Herson discusses how fluctuations in energy levels manifest in changes in motor activity and cognitive function, separate from mood states. The diary entries analyzed show that depressive episodes are characterized by extreme lethargy and cognitive sluggishness, while manic episodes are marked by excessive energy and hyperactivity. This shift in focus from mood to energy challenges common societal views and stigmas surrounding mood disorders, highlighting the role of physiological limitations rather than just emotional swings. Herson’s perspective advocates for a reevaluation of how these disorders are conceptualised, which could lead to more effective treatments that address the underlying physiological factors, such as disruptions in circadian rhythms and mitochondrial dysfunction. This approach may offer a new direction for understanding and managing mood disorders.
