It's important to note that everyone feels anxiety to some degree regularly throughout their life - fear and anxiety are adaptive and helpful emotions that can function to help us notice danger or threat, keep us safe, and help us adapt to the environment. Anxiety disorders represent states when fear or anxiety becomes severe or extreme, to the extent that it causes an individual significant distress, or impairs their ability to function in important facets of life such as work, school, or relationships. It is also important that risk factors don't at all imply that anxiety is anyone's fault; anxiety disorders are a very common difficulty that people experience. In this section, we will review risk factors for anxiety disorders. There are many potential risk factors for anxiety disorders, and most people likely experience multiple different combinations of risk factors, such as neurobiological factors, genetic markers, environmental factors, and life experiences. However, we do not yet fully understand what causes some people to have anxiety disorders.
Panic attacks are extremely unpleasant and can be very frightening. As a result, people who experience repeated panic attacks often become very worried about having another attack and may make changes to their lifestyle so as to avoid having panic attacks. For example, avoiding exercise so as to keep their heart rate low, or avoiding certain places.

Women are more than two times as likely as men to be diagnosed with an anxiety disorder. (6) It’s not clear why this is the case, but researchers have theorized that it may be due to a combination of social and biological factors. Scientists are still investigating the complex role that sex plays in brain chemistry, but some research suggests that in women, the amygdala, which is the part of the brain responsible for processing potential threats, may be more sensitive to negative stimuli and may hold on to the memory of it longer.

Everyone has probably experienced panic, or something like it, at least once in their lifetime: on a disturbingly turbulent plane, or before giving an important presentation, or after realizing you hit reply all when you really, really should not have. We all know the paralyzed feeling and the heightened physical sensations. But panic attacks and panic disorder take a different shape. Panic attacks have many physical symptoms and tend to peak around 10 minutes, and may last for 30. Panic disorder is diagnosed by the frequency of these attacks, and the presence of a fear of having them. 
Antidepressants are medications used to treat symptoms of depression but can also used to treat anxiety symptoms as well. In particular, selective serotonin reuptake inhibitors (SSRIs) and selective norepinephrine reuptake inhibitors (SNRIs) are the primary class of antidepressant used to treat anxiety. SSRIs commonly used to treat anxiety are escitalopram (Lexapro) and paroxetine (Paxil, Pexeva). SNRI medications used to treat anxiety include duloxetine (Cymbalta), venlafaxine (Effexor XR).

The mutism must also include impairment in social, academic, or occupational achievement or functioning to qualify as a diagnosis. Selective mutism is not present if it is related to lack of knowledge or comfort with the spoken language required of the situation or is due to embarrassment from a communication or developmental disorder. The symptoms cannot be better accounted for by another mental disorder or be caused by substances, medications, or medical illness.
A phobia is an unrealistic or exaggerated fear of a specific object, activity, or situation that in reality presents little to no danger. Common phobias include fear of animals (such as snakes and spiders), fear of flying, and fear of heights. In the case of a severe phobia, you might go to extreme lengths to avoid the thing you fear. Unfortunately, avoidance only strengthens the phobia.
Generalized anxiety disorder involves persistent and excessive worry that interferes with daily activities. This ongoing worry and tension may be accompanied by physical symptoms, such as restlessness, feeling on edge or easily fatigued, difficulty concentrating, muscle tension or problems sleeping. Often the worries focus on everyday things such as job responsibilities, family health or minor matters such as chores, car repairs, or appointments.
Separation anxiety disorder: Separation anxiety is often thought of as something that only children deal with; however, adults can also be diagnosed with separation anxiety disorder. People who have separation anxiety disorder have fears about being parted from people to whom they are attached. They often worry that some sort of harm or something untoward will happen to their attachment figures while they are separated. This fear leads them to avoid being separated from their attachment figures and to avoid being alone. People with separation anxiety may have nightmares about being separated from attachment figures or experience physical symptoms when separation occurs or is anticipated.
