Neural circuitry involving the amygdala (which regulates emotions like anxiety and fear, stimulating the HPA Axis and sympathetic nervous system) and hippocampus (which is implicated in emotional memory along with the amygdala) is thought to underlie anxiety.[52] People who have anxiety tend to show high activity in response to emotional stimuli in the amygdala.[53] Some writers believe that excessive anxiety can lead to an overpotentiation of the limbic system (which includes the amygdala and nucleus accumbens), giving increased future anxiety, but this does not appear to have been proven.[54][55]

What is depression and what can I do about it? Depression is a mood disorder characterized by low mood, a feeling of sadness, and a general loss of interest in things. Depression is not a short-term problem and can last for months. There are many types of depression, and it is essential to see a doctor or mental health therapist for correct diagnosis and treatment.

Panic attacks are common among all anxiety disorders but what sets panic disorder apart is that panic attacks are unexpected and occur "out of the blue" without an obvious trigger (American Psychiatric Association, 2013; Craske & Barlow, 2007). These unexpected panic attacks must be associated with a significant change in behavior or be followed by at least one month of persistent worry about having another attack or about what will happen if you have another panic attack.
The Anxiety and Depression Association of America (ADAA) is an international nonprofit membership organization (with more than 1,800 professional mental health members) and a leader in education, training, and research for anxiety, depression and related disorders.  More than 38 million people from around the world visit the ADAA website annually to find current treatment and research information and to access free resources and support. Together we are changing lives.  Welcome!
Panic attacks can happen during the day or night. Some people have one panic attack then don't ever experience another, or you might find that you have them regularly, or several in a short space of time. You might notice that particular places, situations or activities seem to trigger panic attacks. For example, they might happen before a stressful appointment.

Panic attacks involve sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. People experiencing a panic attack may believe they are having a heart attack or they are dying or going crazy. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms:
Buspirone is a drug indicated for the treatment of anxiety. This drug has high efficacy for Generalized Anxiety Disorder and is particularly effective at reducing the cognitive and interpersonal problems associated with anxiety. Unlike benzodiazepines, buspirone does not have a sedative effect or interact with alcohol. Most importantly there is a very low risk of developing a dependence on buspirone. Its side effects are minimal but can include dizziness, nervousness, and headaches. BuSpar and Vanspar are brand names associated with buspirone.
Anxiety during social interactions, particularly between strangers, is common among young people. It may persist into adulthood and become social anxiety or social phobia. "Stranger anxiety" in small children is not considered a phobia. In adults, an excessive fear of other people is not a developmentally common stage; it is called social anxiety. According to Cutting,[32] social phobics do not fear the crowd but the fact that they may be judged negatively.
Panic disorder affects 2-3% of people every year in the United States and Europe, with varying rates depending on race and ethnicity. On average, Native American Indian populations experience panic disorder at higher rates than non-Latino white Americans. In contrast, African Americans, Latinos, Caribbean Blacks, and Asian Americans all experience the disorder at lower rates than non-Latino white Americans. In addition, it has been well established than females are twice as likely to be diagnosed with panic disorder than males (Asnaani, Gutner, Hinton, & Hofmann, 2009; McLean, Asnaani, Litz, & Hofmann, 2011). A number of factors (e.g., biological influences, temperament, exposure to stressors and trauma, cognitive factors, and environmental factors) have been identified as possibly influencing sex differences in rates of panic disorder (McLean & Anderson, 2009). However, no one theory has been determined so the underlying reason for sex differences in rates of panic disorder remains unknown.

Although how long a panic attack lasts can vary greatly, its duration is typically more than 10 minutes. A panic is one of the most distressing conditions that a person can endure, and its symptoms can closely mimic those of a heart attack. Typically, most people who have one panic attack will have others, and when someone has repeated attacks with no other apparent physical or emotional cause and it negatively changes their behavior due to the attacks or feels severe anxiety about having another attack, he or she is said to have panic disorder. A number of other emotional problems can have panic attacks as a symptom. Some of these illnesses include posttraumatic stress disorder (PTSD), obsessive-compulsive disorder, schizophrenia, and intoxication or withdrawal from alcohol and certain other drugs of abuse.
If you have a debilitating fear of being seen negatively by others and humiliated in public, you may have social anxiety disorder, also known as social phobia. Social anxiety disorder can be thought of as extreme shyness. In severe cases, social situations are avoided altogether. Performance anxiety (better known as stage fright) is the most common type of social phobia.
If constant worries and fears distract you from your day-to-day activities, or you’re troubled by a persistent feeling that something bad is going to happen, you may be suffering from generalized anxiety disorder (GAD). People with GAD are chronic worrywarts who feel anxious nearly all of the time, though they may not even know why. Anxiety related to GAD often shows up as physical symptoms like insomnia, stomach upset, restlessness, and fatigue.

Complementary and Alternative Therapies can be used in conjunction with conventional therapies to reduce the symptoms of anxiety. There is a growing interest in these types of alternative therapies, since they are non-invasive and can be useful to patients. They are typically not intended to replace conventional therapies but rather can be an adjunct therapy that can improve the overall quality of life of patients.
As is the case the more generalized forms of social anxiety, intergroup anxiety has behavioral, cognitive, and affective effects. For instance, increases in schematic processing and simplified information processing can occur when anxiety is high. Indeed, such is consistent with related work on attentional bias in implicit memory.[35][36][37] Additionally recent research has found that implicit racial evaluations (i.e. automatic prejudiced attitudes) can be amplified during intergroup interaction.[38] Negative experiences have been illustrated in producing not only negative expectations, but also avoidant, or antagonistic, behavior such as hostility.[39] Furthermore, when compared to anxiety levels and cognitive effort (e.g., impression management and self-presentation) in intragroup contexts, levels and depletion of resources may be exacerbated in the intergroup situation.
Some benefits of benzodiazepines are that they are effective in relieving anxiety and take effect more quickly than antidepressant medications often prescribed for anxiety. Some drawbacks of benzodiazepines are that people can build up a tolerance to them if they are taken over a long period of time and they may need higher and higher doses to get the same effect. Some people may even become dependent on them.
