What factors contribute to the pathogenesis of panic disorder?

When discussing the pathogenesis of panic disorder, several environmental and biological factors are relevant, and one significant factor that has been identified is the impact of smoking during childhood. Research indicates that early exposure to nicotine may modify neurodevelopment and increase vulnerability to anxiety disorders, including panic disorder, later in life. This relationship suggests that childhood smoking can have lasting effects on mental health, potentially altering neurotransmitter systems and stress response mechanisms.

The other options do not align with the established factors contributing to the risk of developing panic disorder. For instance, hypoactivity in the amygdala and hypothalamus can be indicative of a different profile rather than a risk factor for panic disorder. Similarly, having narcissistic personality disorder does not inherently increase one's risk for panic disorder, as personality disorders exhibit different mechanisms of influence. Lastly, low anxiety sensitivity is associated with a decreased likelihood of experiencing panic symptoms rather than an increased risk.

Thus, the connection between smoking in childhood and the later development of panic disorder is backed by research that recognizes the importance of early life experiences and their long-term implications on mental health.
