Review Questions
How does major depressive disorder influence neurotransmitter levels and what role does this play in the symptoms experienced by individuals?
Major depressive disorder is associated with alterations in neurotransmitter levels, particularly serotonin, norepinephrine, and dopamine. These changes can lead to symptoms like fatigue, decreased motivation, and emotional numbness. By disrupting normal communication between neurons in the brain, these neurotransmitter imbalances contribute to the mood dysregulation and cognitive impairments observed in those suffering from the disorder.
Discuss the significance of Cognitive Behavioral Therapy (CBT) as a treatment option for major depressive disorder and its potential effectiveness.
Cognitive Behavioral Therapy (CBT) is significant in treating major depressive disorder as it addresses the negative thought patterns and behaviors that contribute to the disorder. By helping individuals recognize and challenge these thoughts, CBT aims to create healthier cognitive habits. Research shows that CBT can be as effective as medication for some patients and often serves as a complementary treatment alongside antidepressants.
