   A sudden attack of anxiety.


A psychological and/or biological response to stress. Feelings of anxiety involve discomforting apprehension or concern, which may include symptoms such as cognitive difficulties, hypersensitivity, dizziness, muscular weakness, breathing difficulties, irregular heart beat, sweating, and sensations of fear. Typically, anxiety is a natural and healthy response to life experiences. However, exaggerated or chronic anxiety often indicates an anxiety disorder. Anxiety can be produced by external stress (exogenous anxiety) or internal stress (endogenous anxiety).


Panic attacks
Discrete periods of sudden onset of intense apprehension, fearfulness, or terror, often associated with feelings of impending doom. During these attacks there are symptoms such as shortness of breath or smothering sensations; palpitations, pounding heart, or accelerated heart rate; chest pain or discomfort; choking; and fear of going crazy or losing control. Panic attacks may be unexpected (uncued), in which the onset of the attack is not associated with a situational trigger and instead occurs "out of the blue"; situationally bound, in which the panic attack almost invariably occurs immediately on exposure to, or in anticipation of, a situational trigger ("cue"); and situationally predisposed, in which the panic attack is more likely to occur on exposure to a situational trigger but is not invariably associated with it.

Panic button
A button to push in order to summon help in case of an emergency. This device triggers an alarm when activated by its user. The alarm system may respond by activating the sirens or sending a silent alarm to a medical alarm monitoring central station.

Panic disorder
Panic disorder is a condition in which persons experience sudden, severe attacks of anxiety. Symptoms consist of heart palpitations, shortness of breath, sweating, dizziness, upset stomach and fear of dying or losing control. Some patients have such attacks only occasionally, while others may have several attacks a day. Since the attacks are very frightening, many patients start to avoid situations in which the attacks have occurred, such as driving on an expressway or over bridges, shopping in large department stores or malls, etc. Agoraphobia is the term for such avoidance, which in severe cases can lead to being completely housebound.
