Anxiety attacks that occur while sleeping, also called nocturnal panic attacks, occur less often than panic attacks during the daytime but affect about 40%-70% of those who suffer from daytime panic attacks. This symptom is also important because people who suffer from panic symptoms during sleep tend to have more respiratory distress associated with their panic. They also tend to experience more symptoms of depression and other psychiatric disorders compared to people who do not have panic attacks at night. Nocturnal panic attacks tend to cause sufferers to wake suddenly from sleep in a state of sudden fear or dread for no apparent reason. In contrast to people with sleep apnea and other sleep disorders, sufferers of nocturnal panic can have all the other symptoms of a panic attack. The duration of nocturnal panic attacks tends to be less than 10 minutes, but it can take much longer to fully calm down for those who experience them.
Simple Phobias and Agoraphobia: People with panic disorder often develop irrational fears of specific events or situations that they associate with the possibility of having a panic attack. Fear of heights and fear of crossing bridges are examples of simple phobias. As the frequency of panic attacks increases, the person often begins to avoid situations in which they fear another attack can occur or places where help would not be immediately available. This avoidance may eventually develop into agoraphobia, an inability to go beyond known and safe surroundings because of intense fear and anxiety. Generally, these fears can be resolved through repeated exposure to the dreaded situations, while practicing specific techniques to become less sensitive to them.
Many people experience their first panic attack due a build up of chronic stress. Anxious personalities often then become afraid of them, which further stresses the body. As fear and stress increase, so does the likelihood of a subsequent panic attack. This scenario is a common catalyst into Panic Attack Disorder: becoming afraid of the feelings and symptoms of a panic attack, which causes further panic attacks.
Anxiety disorders are the most commonly diagnosed mental disorders in the United States. The most common type of anxiety disorder are called “simple phobias,” which includes phobias of things like snakes or being in a high place. Up to 9 percent of the population could be diagnosed with this disorder in any given year. Also common are social anxiety disorder (social phobia, about 7 percent) — being fearful and avoiding social situations — and generalized anxiety disorder (about 3 percent).
Comorbidity is more common than not with anxiety disorders, meaning that most individuals who experience significant anxiety experience multiple different types of anxiety. Given this co-morbidity, it is not surprising that many risk factors are shared across anxiety disorders, or have the same underlying causes. There is a lot of research identifying risk factors for anxiety disorders, and this research suggests that both nature and nurture are very relevant. It is important to note that no single risk factor is definitive - many people may have a risk factor for a disorder, and not ever develop that disorder. However, it is helpful for research to identify risk factors and for people to be aware of them, as being aware of who might be at risk can potentially help people get support or assistance in order to prevent the development of a disorder.
Social anxiety disorder (previously called social phobia): People with social anxiety disorder have a general intense fear of, or anxiety toward, social or performance situations. They worry that actions or behaviors associated with their anxiety will be negatively evaluated by others, leading them to feel embarrassed. This worry often causes people with social anxiety to avoid social situations. Social anxiety disorder can manifest in a range of situations, such as within the workplace or the school environment.
