Fear and anxiety can be differentiated in four domains: (1) duration of emotional experience, (2) temporal focus, (3) specificity of the threat, and (4) motivated direction. Fear is short lived, present focused, geared towards a specific threat, and facilitating escape from threat; anxiety, on the other hand, is long-acting, future focused, broadly focused towards a diffuse threat, and promoting excessive caution while approaching a potential threat and interferes with constructive coping.
About 12% of people are affected by an anxiety disorder in a given year and between 5-30% are affected at some point in their life. They occur about twice as often in women than they do in men, and generally begin before the age of 25. The most common are specific phobia which affects nearly 12% and social anxiety disorder which affects 10% at some point in their life. They affect those between the ages of 15 and 35 the most and become less common after the age of 55. Rates appear to be higher in the United States and Europe.
If you're having lots of panic attacks at unpredictable times and there doesn't seem to be a particular trigger or cause, you might be given a diagnosis of panic disorder. It's common to experience panic disorder and agoraphobia (a type of phobia) together. People who experience panic disorder may have some periods with few or no panic attacks, but have lots at other times.
If left untreated, anxiety may worsen to the point at which the person's life is seriously affected by panic attacks and by attempts to avoid or conceal them. In fact, many people have had problems with friends and family, failed in school, and/or lost jobs while struggling to cope with this condition. There may be periods of spontaneous improvement in the episodes, but panic attacks do not usually go away unless the person receives treatments designed specifically to help people with these symptoms.
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.
The person being treated will be closely monitored for the possibility of side effects that can range from minor to severe and can sometimes even be life-threatening. Because of the possible risks to the fetus of a mother being treated with medications for panic attacks, psychotherapy continues to be the treatment of first choice when treatment of this symptom is given during pregnancy.
People with generalized anxiety disorder (GAD) display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.
