Depression and mania are two contrasting mood states with distinct neurobiological underpinnings that significantly affect brain functioning. Understanding these states from a neurobiological perspective can aid clinicians in effectively communicating these experiences to clients. This essay explores the neurobiological mechanisms involved in depression and mania, along with insights gained from the Preston and Bentley readings and the week’s multimedia resources.

During depression, neurobiological changes primarily involve dysregulation of neurotransmitters such as serotonin, norepinephrine, and dopamine. These chemicals play essential roles in mood regulation, and their imbalance leads to the persistent feelings of sadness, hopelessness, and lack of motivation characteristic of depression (Meyer et al., 2020). From a neuroanatomical standpoint, depression is associated with decreased activity in the prefrontal cortex, which is involved in decision-making and emotional regulation, and increased activity in the amygdala, which processes fear and threat-related stimuli (Drevets et al., 2008). Additionally, hippocampal volume reduction has been observed in individuals with depression, likely due to chronic stress and elevated cortisol levels impairing neurogenesis (Campbell & MacQueen, 2004). These neurobiological alterations result in the brain's diminished capacity to regulate mood and emotional responses effectively.

In contrast, mania is characterized by heightened brain activity and neurotransmitter dysregulation, particularly involving increased dopamine transmission (Grace et al., 2007). During manic episodes, there is often hyperactivity in the mesolimbic dopamine pathway, which contributes to elevated mood, increased energy, and impulsivity. Neuroimaging studies reveal increased activity in the amygdala and decreased activity in the prefrontal cortex, indicating impaired emotional regulation and decision-making capabilities (Strakowski et al., 2012). These neurobiological changes produce the euphoric, expansive, and sometimes irritable moods seen in mania. Moreover, functional abnormalities in neural circuits governing reward processing exacerbate symptoms like risk-taking and overconfidence.

To convey these complex neurobiological phenomena to clients, clinicians should describe depression as a state where the brain’s chemistry and neural circuits are out of balance, leading to feelings of sadness and hopelessness. Explaining that neurotransmitter imbalances diminish the brain's ability to regulate emotions can help clients understand their experiences are rooted in brain function rather than personal weakness. Conversely, mania can be explained as a state of overactivity in brain circuits responsible for mood and energy, resulting in feelings of exuberance and impulsiveness. Emphasizing that these states are due to shifts in brain chemistry and activity can foster understanding and reduce feelings of shame or stigma.

From the Preston and Bentley readings and the week’s multimedia content, two key insights emerge. First, the importance of neuroplasticity in mood regulation highlights that brain circuits involved in depression and mania are not fixed but can be modulated through therapeutic interventions such as medication and psychotherapy (Preston & Bentley, 2021). Second, the integration of biological and psychological models of mood disorders underscores the necessity for holistic treatment approaches that address both neurochemical imbalances and psychosocial factors. These insights reinforce the importance of comprehensive treatment plans tailored to individual neurobiological and psychological profiles.
