Panic attacks are sudden, discrete periods of intense anxiety, fear and discomfort that are associated with a variety of somatic and cognitive symptoms. The onset of these episodes is typically abrupt, and may have no obvious trigger. Although these episodes may appear random, they are considered to be a subset of an evolutionary response commonly referred to as fight or flight that occur out of context, flooding the body with hormones (particularly adrenalin) that aid in defending itself from harm.

According to the American Psychological Association the symptoms of a panic attack commonly last approximately ten minutes. However, panic attacks can be as short as 1-5 minutes, while more severe panic attacks may form a cyclic series of episodes, lasting for an extended period, sometimes hours. Often those afflicted will experience significant anticipatory anxiety in between attacks and in situations where attacks have previously occurred.

Panic Attacks also affect people differently. Experienced sufferers may be able to completely 'ride out' a panic attack with little to no obvious symptoms. Others, notably first time sufferers, may even call for emergency services; many who experience a panic attack for the first time fear they are having a heart attack or a nervous breakdown.(Wilson 1996)

Descriptions
Many who suffer from panic attacks state they are the most frightening experiences of their lives. Sufferers of panic attacks report a fear or sense of dying, "going crazy", and/ or experiencing a heart attack, feeling faint, nauseous, or losing control of themselves. These feelings may provoke a strong urge to escape or flee the place where the attack began (a consequence of the sympathetic "fight or flight" response).

A panic attack is a response of the sympathetic nervous system (SNS). The most common symptoms may include: trembling, dyspnea (shortness of breath), heart palpitations, chest pain (or chest tightness), sweating, nausea, dizziness (or slight vertigo), light-headedness, hyperventilation, paresthesias (tingling sensations), sensations of choking or smothering or derealization, or the feeling that nothing is real. These physical symptoms are interpreted with alarm in people prone to panic attacks. This results in increased anxiety, and forms a positive feedback loop.Despite the multitude of symptoms and the afflicted's fears a panic attack presents no real danger.

Often when shortness of breath and chest pain are the predominant symptoms the sufferer incorrectly appraises this as a sign or symptom of a heart attack. This results in the person experiencing a panic attack to seek treatment in an emergency room.

The panic attack is distinguished from other forms of anxiety by its intensity and its sudden, episodic nature.Panic attacks are often experienced in conjunction with anxiety disorders and other psychological conditions, although panic attacks are not always indicative of a mental disorder, nor are they uncommon. Up to 10 percent of otherwise healthy people experience an isolated panic attack about once per year, and 1 in 60 people in the U.S. will suffer from a panic disorder at some point in their lifetime.
