Panic disorder
an anxiety disorder characterized by recurring severe panic attacks. It may also include significant behavioral changes lasting at least a month and of ongoing worry about the implications or concern about having other attacks
Panic disorder
Panic attacks cannot be predicted, therefore an individual may become stressed, anxious or worried wondering when the next panic attack will occur
Because of the intense symptoms that accompany panic disorder, it may be mistaken for a life-threatening physical illness such as a heart attack. This misconception often aggravates or triggers future attacks (some are called Anticipatory Attacks). People frequently go to hospital emergency rooms when they are having panic attacks, and extensive medical tests may be performed to rule out these other conditions, thus creating further anxiety. There are three types of panic attacks: unexpected, situationally bounded and situationally predisposed
Signs and symptoms
Panic disorder sufferers usually have a series of intense episodes of extreme anxiety during panic attacks. These attacks typically last about ten minutes, and can be as short-lived as 1–5 minutes, but can last twenty minutes to more than an hour, or until helpful intervention is made,
rapid heartbeat, perspiration, dizziness, dyspnea, trembling
Signs and symptoms
uncontrollable fear such as: the fear of losing control and going crazy, the fear of dying and hyperventilationOther symptoms are sweating, a sensation of choking, chest pain, nausea, numbness or tingling, chills or hot flashes, faintness and some sense of altered reality
Diagnosis
unexpected, recurrent panic attacks, followed in at least one instance by at least a month of a significant and related behavior change, a persistent concern of more attacks, or a worry about the attack's consequences. There are two types, one with and one without agoraphobia. Diagnosis is excluded by attacks due to a drug or medical condition, or by panic attacks that are better accounted for by other mental disorders
Treatment
PsychotherapyMedicationAntidepressants SSRIs, MAOIs, tricyclic Anti-antidepressantsAnti-anxiety drugs benzodiazepines
Phobia
persistent fear of an object or situation in which the sufferer commits to great lengths in avoiding, typically disproportional to the actual danger posed
Social phobia
fears other people or social situations such as performance anxiety or fears of embarrassment by scrutiny of others, such as eating in public. Overcoming social phobia is often very difficult without the help of therapy or support groups
Specific phobias
fear of a single specific panic trigger such as spiders, snakes, dogs, water, heights, flying, catching a specific illness
Claustrophobia
the fear of having no escape and being closed in small spaces or rooms (opposite: claustrophilia). It is typically classified as an anxiety disorder and often results in panic attack, and can be the result of many situations or stimuli, including elevators crowded to capacity, windowless rooms, and even tight-necked clothing
Agoraphobia
a generalized fear of leaving home or a small familiar 'safe' area, and of possible panic attacks that might follow.
Treatments
Cognitive behavioral therapyEye Movement Desensitization and Reprocessing
Hypnotherapy
Agoraphobia
Agoraphobia is a condition where the sufferer becomes anxious in environments that are unfamiliar or where he or she perceives that they have little control.
Posttraumatic stress disorder
severe anxiety disorder that can develop after exposure to any event that results in psychological trauma. This event may involve the threat of death to oneself or to someone else, or to one's own or someone else's physical, sexual, or psychological integrity,
overwhelming the individual's ability to cope.
Signs and symptoms
Diagnostic symptoms for PTSD include re-experiencing the original trauma(s) through flashbacks or nightmares, avoidance of stimuli associated with the trauma, and increased arousal—such as difficulty falling or staying asleep, anger, and hypervigilance.
Diagnosis
A: Exposure to a traumatic eventB: Persistent re-experiencingC: Persistent avoidance and emotional numbingD: Persistent symptoms of increased arousal not present beforeE: Duration of symptoms for more than 1 monthF: Significant impairment
