Review Questions

• What are the key differences between the manic and depressive phases of bipolar disorder?
  • The manic phase of bipolar disorder is characterized by heightened energy, reduced need for sleep, racing thoughts, and impulsive behavior. In contrast, the depressive phase involves feelings of sadness, hopelessness, fatigue, and loss of interest in activities. Understanding these phases is crucial for recognizing symptoms and determining appropriate treatment strategies for individuals with bipolar disorder.
• How do mood stabilizers like lithium play a role in the management of bipolar disorder?
  • Mood stabilizers such as lithium are vital in managing bipolar disorder as they help prevent both manic and depressive episodes. They work by regulating neurotransmitter levels in the brain, which contributes to mood stabilization. Regular monitoring is necessary due to potential side effects and the need for dosage adjustments to maintain therapeutic levels.
• Evaluate the impact of untreated bipolar disorder on an individual's overall well-being and life outcomes.
  • Untreated bipolar disorder can lead to significant impairments in various aspects of an individual's life, including relationships, employment, and physical health. The extreme mood swings can result in erratic behaviors that alienate friends and family, while prolonged depressive episodes can hinder job performance and educational pursuits. Moreover, individuals may engage in risky behaviors during manic phases or experience suicidal ideation during depressive phases. This highlights the importance of early diagnosis and effective treatment to enhance overall well-being and life satisfaction.
