Paula had her first panic attack six months ago. She was in her office preparing for an important work presentation when, suddenly, she felt an intense wave of fear. Then the room started spinning and she felt like she was going to throw up. Her whole body was shaking, she couldn’t catch her breath, and her heart was pounding out of her chest. She gripped her desk until the episode passed, but it left her deeply shaken.
People who have had a panic attack in certain situations may develop irrational fears, called phobias, of these situations and begin to avoid them. Eventually, the pattern of avoidance and level of anxiety about another attack may reach the point where individuals with panic disorder are unable to drive or even step out of the house. At this stage, the person is said to have panic disorder with agoraphobia.
Your heart beats fast, and your breathing speeds up. Your chest may feel tight, and you might start to sweat. If you've ever felt it, you know that anxiety is just as much a physical state as a mental state. That's because there's a very strong biological chain reaction that occurs when we encounter a stressful event or begin to worry about potential stressors or dangers in the future. Other physical symptoms include sweating, headaches, and insomnia. Psychological symptoms may include feeling restless or irritable, feeling tense, having a feeling of dread, or experiencing ruminative or obsessive thoughts.
Biological causes may include obsessive compulsive disorder, Postural Orthostatic Tachycardia Syndrome, post traumatic stress disorder, hypoglycemia, hyperthyroidism, Wilson's disease, mitral valve prolapse, pheochromocytoma, and inner ear disturbances (labyrinthitis). Dysregulation of the norepinephrine system in the locus ceruleus, an area of the brain stem, has been linked to panic attacks.
Occasional anxiety is an expected part of life. You might feel anxious when faced with a problem at work, before taking a test, or before making an important decision. But anxiety disorders involve more than temporary worry or fear. For a person with an anxiety disorder, the anxiety does not go away and can get worse over time. The symptoms can interfere with daily activities such as job performance, school work, and relationships.
