Panic Attack Symptoms

Panic attacks involve sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. A person experiencing a panic attack may believe that he or she is having a heart attack or that death is imminent. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms:

• "Racing" heart
• Feeling weak, faint, or dizzy
• Tingling or numbness in the hands and fingers
• Sense of terror, or impending doom or death
• Feeling sweaty or having chills
• Chest pains
• Breathing difficulties
• Feeling a loss of control

Panic attacks are generally brief, lasting less than 10 minutes, although some of the symptoms may persist for a longer time. People who have had one panic attack are at greater risk for having subsequent panic attacks than those who have never experienced a panic attack. When the attacks occur repeatedly, a person is considered to have a condition known as panic disorder.

People with panic disorder may be extremely anxious and fearful, since they are unable to predict when the next episode will occur. Panic disorder is fairly common and affects about 2.4 million people in the U.S., or 1.7% of the adult population between the ages of 18 and 54. Women are twice as likely as men to develop the condition, and its symptoms usually begin in early adulthood.

It is not clear what causes panic disorder. In many people who have the biological vulnerability to panic attacks, they may develop in association with major life changes (such as getting married, having a child, starting a first job, etc.) and major lifestyle stressors. There is also some evidence that suggests that the tendency to develop panic disorder may run in families. People who suffer from panic disorder are also more likely than others to suffer from depression, attempt suicide, or to abuse alcohol or drugs.

Luckily for sufferers of frequent panic attacks, panic disorder is a treatable condition. Psychotherapy and medications have both been used, either singly or in combination, for successful treatment of panic disorder. If medication is necessary, your doctor may prescribe antianxiety medications, antidepressants that also have antianxiety properties, or a class of heart medications known as beta-blockers to help control the episodes in panic disorder.

There are many different conditions that are recognized as mental illnesses. The more common types include:

• Anxiety disorders: People with anxiety disorders respond to certain objects or situations with fear and dread, as well as with physical signs of anxiety or nervousness, such as a rapid heartbeat and sweating. An anxiety disorder is diagnosed if the person's response is not appropriate for the situation, if the person cannot control the response, or if the anxiety interferes with normal functioning. Anxiety disorders include generalized anxiety disorder, post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), panic disorder, social anxiety disorder, and specific phobias.
• Mood disorders: These disorders, also called affective disorders, involve persistent feelings of sadness or periods of feeling overly happy, or fluctuations from extreme happiness to extreme sadness. The most common mood disorders are depression, mania, and bipolar disorder.
• Psychotic disorders: Psychotic disorders involve distorted awareness and thinking. Two of the most common symptoms of psychotic disorders are hallucinations -- the experience of images or sounds that are not real, such as hearing voices -- and delusions, which are false beliefs that the ill person accepts as true, despite evidence to the contrary. Schizophrenia is an example of a psychotic disorder.
• Eating disorders: Eating disorders involve extreme emotions, attitudes, and behaviors involving weight and food. Anorexia nervosa, bulimia nervosa and binge eating disorder are the most common eating disorders.
• Impulse control and addiction disorders: People with impulse control disorders are unable to resist urges, or impulses, to perform acts that could be harmful to themselves or others. Pyromania (starting fires), kleptomania (stealing), and compulsive gambling are examples of impulse control disorders. Alcohol and drugs are common objects of addictions. Often, people with these disorders become so involved with the objects of their addiction that they begin to ignore responsibilities and relationships.
• Personality disorders: People with personality disorders have extreme and inflexible personality traits that are distressing to the person and/or cause problems in work, school, or social relationships. In addition, the person's patterns of thinking and behavior significantly differ from the expectations of society and are so rigid that they interfere with the person's normal functioning. Examples include antisocial personality disorder, obsessive-compulsive personality disorder, and paranoid personality disorder.

Other, less common types of mental illnesses include:

• Adjustment disorder: Adjustment disorder occurs when a person develops emotional or behavioral symptoms in response to a stressful event or situation. The stressors may include natural disasters, such as an earthquake or tornado; events or crises, such as a car accident or the diagnosis of a major illness; or interpersonal problems, such as a divorce, death of a loved one, loss of a job, or a problem with substance abuse. Adjustment disorder usually begins within three months of the event or situation and ends within six months after the stressor stops or is eliminated.
• Dissociative disorders: People with these disorders suffer severe disturbances or changes in memory, consciousness, identity, and general awareness of themselves and their surroundings. These disorders usually are associated with overwhelming stress, which may be the result of traumatic events, accidents, or disasters that may be experienced or witnessed by the individual. Dissociative identity disorder, formerly called multiple personality disorder, or "split personality," and depersonalization disorder are examples of dissociative disorders.
• Factitious disorders: Factitious disorders are conditions in which physical and/or emotional symptoms are created in order to place the individual in the role of a patient or a person in need of help.
• Sexual and gender disorders: These include disorders that affect sexual desire, performance, and behavior. Sexual dysfunction, gender identity disorder, and the paraphilias are examples of sexual and gender disorders.
• Somatoform disorders: A person with a somatoform disorder, formerly known as psychosomatic disorder, experiences physical symptoms of an illness, even though a doctor can find no medical cause for the symptoms.
• Tic disorders: People with tic disorders make sounds or display body movements that are repeated, quick, sudden, and/or uncontrollable. (Sounds that are made involuntarily are called vocal tics.) Tourette's syndrome is an example of a tic disorder.

Other diseases or conditions, including various sleep-related problems and many forms of dementia, including Alzheimer's disease, are sometimes classified as mental illnesses, because they involve the brain.
