Review Questions

• How does narcolepsy affect daily life and what strategies can individuals use to manage its symptoms?
  • Narcolepsy significantly impacts daily life by causing excessive daytime sleepiness, which can interfere with work, school, and social activities. Individuals can manage symptoms by maintaining a regular sleep schedule, taking short naps when needed, and using medications prescribed by healthcare providers. Additionally, lifestyle changes such as regular exercise and avoiding caffeine or alcohol can help improve overall alertness.
• Discuss the relationship between narcolepsy and cataplexy, including how they influence each other.
  • Narcolepsy and cataplexy are closely related, as cataplexy is one of the primary symptoms of Type 1 narcolepsy. Cataplexy involves sudden muscle weakness triggered by strong emotions like laughter or surprise, leading to potential falls or injuries. The presence of cataplexy often indicates a more severe form of narcolepsy and requires specialized treatment strategies to prevent both daytime drowsiness and episodes of muscle weakness.
• Evaluate the impact of narcolepsy on an individual's psychological well-being and social interactions.
  • Narcolepsy can have profound effects on an individual's psychological well-being due to the challenges posed by excessive daytime sleepiness and sudden sleep attacks. This unpredictability may lead to social isolation, anxiety, and depression as individuals struggle to participate in social activities or maintain employment. The stigma surrounding sleep disorders may further exacerbate feelings of inadequacy or frustration, highlighting the importance of supportive therapies and education for both individuals and their communities.
