Final answer:
A likely symptom of a disease that disrupts the functioning of the sympathetic nervous system is decreased fight-or-flight response.
Step-by-step explanation:
A likely symptom of a disease that disrupts the functioning of the sympathetic nervous system is decreased fight-or-flight response. The sympathetic nervous system is responsible for activating the fight-or-flight response, which prepares the body to respond to stressors, such as danger or threats.
When the functioning of the sympathetic nervous system is disrupted, the fight-or-flight response may be impaired, leading to a decreased ability to respond to stressful situations.
