Physical symptoms of an anxiety disorder can be easily confused with other medical conditions, like heart disease or hyperthyroidism. Therefore, a doctor will likely perform an evaluation involving a physical examination, an interview and lab tests. After ruling out an underlying physical illness, a doctor may refer a person to a mental health professional for evaluation.
Over time, many who suffer panic attacks develop an on-going fear of having another attack. This fear can severely hamper daily activities and overall quality of life. Some people refuse to leave their houses or to put themselves in situations that remind them of their previous attacks. Agoraphobia (a fear of being outside of known and safe surroundings) or other mental problems may follow.
The first step is to see your doctor to make sure there is no physical problem causing the symptoms. If an anxiety disorder is diagnosed, a mental health professional can work with you on the best treatment. Unfortunately, many people with anxiety disorders don’t seek help. They don’t realize that they have an illness that has effective treatments.
Anxiety can be either a short-term "state" or a long-term "trait". Whereas trait anxiety represents worrying about future events, anxiety disorders are a group of mental disorders characterized by feelings of anxiety and fear.[10] Anxiety disorders are partly genetic but may also be due to drug use, including alcohol, caffeine, and benzodiazepines (which are often prescribed to treat anxiety), as well as withdrawal from drugs of abuse. They often occur with other mental disorders, particularly bipolar disorder, eating disorders, major depressive disorder, or certain personality disorders. Common treatment options include lifestyle changes, medication, and therapy. Metacognitive therapy seeks to diminish anxiety through reducing worry, which is seen[by whom?] as a consequence of metacognitive beliefs.[11]
If you’re experiencing a lot of physical anxiety symptoms, you should start by getting a medical checkup. Your doctor can check to make sure that your anxiety isn’t caused by a medical condition, such as a thyroid problem, hypoglycemia, or asthma. Since certain drugs and supplements can cause anxiety, your doctor will also want to know about any prescriptions, over-the-counter medications, herbal remedies, and recreational drugs you’re taking.
Genetics and family history (e.g., parental anxiety) may predispose an individual for an increased risk of an anxiety disorder, but generally external stimuli will trigger its onset or exacerbation.[57] Genetic differences account for about 43% of variance in panic disorder and 28% in generalized anxiety disorder.[58] Although single genes are neither necessary nor sufficient for anxiety by themselves, several gene polymorphisms have been found to correlate with anxiety: PLXNA2, SERT, CRH, COMT and BDNF.[59][60][61] Several of these genes influence neurotransmitters (such as serotonin and norepinephrine) and hormones (such as cortisol) which are implicated in anxiety. The epigenetic signature of at least one of these genes BDNF has also been associated with anxiety and specific patterns of neural activity.[62]
For me it’s knowing or believing I don’t have enough time to finish an assignment, and then I feel like a failure. Right now, I’m doing the most difficult assignment of my life, and if I don’t finish it on time, my graduation will be delayed. This is on top of all my other responsibilities. And to think that I’m supposed to have an accommodation for extra time. Ha! The university and the state don’t care. They just want me to fail so I have to dish out more money to line the pockets of the corporation that assigned this required project.

There are dozens of drugs that can be prescribed to treat anxiety. Since each person responds to medication differently, there's no one drug that works perfectly for everyone. You may have to work a little with a psychiatrist to find the right medication, or the right combination of medicines, that’s most beneficial to you. The drugs that are used to treat anxiety over a long period of time are antidepressants, which affect serotonin, norepinephrine, and other neurotransmitters in the brain.
A person with panic disorder experiences sudden and repeated panic attacks—episodes of intense fear and discomfort that reach a peak within a few minutes—during which time the individual experiences physical symptoms such as chest pain, heart palpitations, breathlessness, vertigo, or abdominal distress, sometimes accompanied by the fear of dying or of going insane.  These symptoms may seem similar to those of a heart attack or other life-threatening medical conditions. Panic disorder is often diagnosed after medical tests or emergency room visits have ruled out other serious illnesses.
Specialized coils that targetes deeper brain regions than rTMS. A patient wears a cushioned helmet (similar to the type of helmet worn during an fMRI). The coil used in dTMS was approved by the FDA in 2013 for treating depression but is currently being studied for the treatment of anxiety disorders such as OCD. The procedue is administered for 20 minutes for 4-6 weeks. Patients can resume their daily lives right after each treatment.

People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
