Some of these symptoms will most likely be present in a panic attack. The attacks can be so disabling that the person is unable to express to others what is happening to them. A doctor might also note various signs of panic: The person may appear to be very afraid or shaky or be hyperventilating (deep, rapid breathing that causes dizziness). Anxiety attacks that take place while sleeping, also called nocturnal panic attacks, occur less often than do panic attacks during the daytime, but affect a large percentage of people who suffer from daytime panic attacks. Individuals with nocturnal panic attacks tend to have more respiratory symptoms associated with panic and have more symptoms of depression and of other psychiatric disorders compared to people who do not have panic attacks at night. Nocturnal panic attacks tend to result in sufferers waking suddenly from sleep in a state of sudden fright or dread for no known reason. As opposed to people with sleep apnea and other sleep disorders, sufferers of nocturnal panic can have all the other symptoms of a panic attack. Although nocturnal panic attacks usually last no more than 10 minutes, it can take much longer for the person to fully recover from the episode.
Anxiety disorders increase one's chances for suffering from other medical illness, such as cardiovascular disorders, including obesity, heart disease and diabetes. More specifically, increased body weight and abdominal fat, high blood pressure, and greater levels of cholesterol, triglycerides, and glucose have all been linked to anxiety. While it is still unclear what causes the high co-morbidity between anxiety and bad physical health outcomes, research suggests that changes in underlying biology that is characteristic of anxiety may also facilitate the emergence for these other physical health outcomes over time. For example, changes in stress hormones, autonomic responses, as well as heightened systemic inflammation are all associated with anxiety disorders and negative health outcomes. These shared physiological states suggest a shared underlying biology and that anxiety maybe a whole-body condition.

Social Anxiety Disorder;Fear of social situations in which the person is exposed to unfamiliar people or to possible scrutiny by others. The individual fears that he or she will act in a way (or show anxiety symptoms) that will be embarrassing and humiliating, often times leading to avoidance of social situations and severe distress when participation in social situations can't be avoided. 
Have you ever worried about your health? Money? The well-being of your family? Who hasn’t, right? These are common issues we all deal with and worry about from time to time. However, if you find yourself in constant worry over anything and everything in your life, even when there should be no cause for concern, you might be suffering from Generalized Anxiety Disorder. People with this condition often recognize they are “over-worrying” about a lot of issues, but have no control over the worry and associated anxiety. It is constant and can interfere with your ability to relax or sleep well and can cause you to startle easily.
Panic disorder involves repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes (panic attacks). You may have feelings of impending doom, shortness of breath, chest pain, or a rapid, fluttering or pounding heart (heart palpitations). These panic attacks may lead to worrying about them happening again or avoiding situations in which they've occurred.
In a decision context, unpredictability or uncertainty may trigger emotional responses in anxious individuals that systematically alter decision-making. There are primarily two forms of this anxiety type. The first form refers to a choice in which there are multiple potential outcomes with known or calculable probabilities. The second form refers to the uncertainty and ambiguity related to a decision context in which there are multiple possible outcomes with unknown probabilities.
Once the diagnosis of panic attack is made, however, the person may be surprised that no medicines are prescribed. Before medications are started, the person requires further evaluation by a mental-health professional to check for the presence of other mental-health disorders. These may include anxiety disorders, depression, or panic disorder (a different diagnosis than panic attack).
If you, or someone you know, has symptoms of anxiety disorder, visit a clinician, who can help determine whether the symptoms are due to an anxiety disorder, medical condition or both. Frequently, the next step in getting treatment for an anxiety disorder is referral to a mental health professional such as a psychiatrist, psychologist, social worker or counselor.
But flashbacks may occur with other types of anxiety as well. Some research, including a 2006 study in the Journal of Anxiety Disorders, suggests that some people with social anxiety have PTSD-like flashbacks of experiences that might not seem obviously traumatic, such as being publicly ridiculed. These people may even avoid reminders of the experience—another symptom reminiscent of PTSD.
Anxiety disorders can often be addressed successfully with a combination of therapy and medication. For therapy, patients may undergo psychotherapy or cognitive behavioral therapy, in which they learn to change how they respond to situations that induce anxiety. For medications, clinicians may, for limited periods of time, prescribe antidepressants such as selective serotonin reuptake inhibitors or tricyclics, tranquilizers such as benzodiazepines; they may also prescribe beta blockers for specific events. Different strategies can also help people who experience feelings of anxiety but the severity of which falls below the clinical threshold for diagnosis. Habits such as exercising, sleeping well, and limiting the amount of caffeine and alcohol consumed can prove helpful. Strategies such as taking deep breaths, acknowledging limits to fully controlling situations, pushing back against anxious or irrational thoughts, and observing the circumstances that tend to produce anxiety are proven to reduce anxiety by helping people feel better prepared in the future.
Selective mutism: A somewhat rare disorder associated with anxiety is selective mutism. Selective mutism occurs when people fail to speak in specific social situations despite having normal language skills. Selective mutism usually occurs before the age of 5 and is often associated with extreme shyness, fear of social embarrassment, compulsive traits, withdrawal, clinging behavior, and temper tantrums. People diagnosed with selective mutism are often also diagnosed with other anxiety disorders.
