What are the biological factors contribute to panic disorder ?

Expert Solution
Step 1

Anxiety disorders, such as panic disorder, are categorized as such. It creates panic attacks, which are sudden emotions of anxiety in the absence of a true threat. Panic attacks can strike at any time and place, with no warning. Women are more likely than men to have panic attacks. It usually begins in the early adolescent years. When a person is under a great deal of stress, it can sometimes start. Treatment usually improves people's health. Before panic sets in, therapy can teach how to notice and change the thought patterns. Medications may also be of assistance.

Step 2

Neurotransmitters or messengers in the brain include serotonin, norepinephrine, and dopamine. They are thought to alter one's mood and anxiety levels by sending messages between different parts of the brain. An imbalance of one or more of these substances, according to one idea, causes panic disorder symptoms.
