Anxiety Disorder

 

Occasional anxiety is an expected part of life. You might feel anxious when faced with a problem at work, before taking a test, or before making an important decision. But anxiety disorders involve more than temporary worry or fear. For a person with an anxiety disorder, the anxiety does not go away and can get worse over time. The symptoms can interfere with daily activities such as job performance, school work, and relationships.

Anxiety is a normal reaction to stress and can be beneficial in some situations. It can alert us to dangers and help us prepare and pay attention. Anxiety disorders differ from normal feelings of nervousness or anxiousness and involve excessive fear or anxiety. Anxiety disorders are the most common of mental disorders and affect nearly 30% of adults at some point in their lives. But anxiety disorders are treatable and a number of effective treatments are available. Treatment helps most people lead normal productive lives.

Anxiety refers to anticipation of a future concern and is more associated with muscle tension and avoidance behavior.

Fear is an emotional response to an immediate threat and is more associated with a fight or flight reaction – either staying to fight or leaving to escape danger.

Anxiety disorders can cause people to try to avoid situations that trigger or worsen their symptoms. Job performance, school work and personal relationships can be affected. In general, for a person to be diagnosed with an anxiety disorder, the fear or anxiety must:

There are several types of anxiety disorders, including generalized anxiety disorder, panic disorder, and various phobia-related disorders.

Generalized Anxiety Disorder

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.

Generalized anxiety disorder symptoms include:

Panic Disorder

People with panic disorder have recurrent unexpected panic attacks. Panic attacks are sudden periods of intense fear that come on quickly and reach their peak within minutes. Attacks can occur unexpectedly or can be brought on by a trigger, such as a feared object or situation.

During a panic attack, people may experience:

People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).

Phobia-related disorders

A phobia is an intense fear of—or aversion to—specific objects or situations. Although it can be realistic to be anxious in some circumstances, the fear people with phobias feel is out of proportion to the actual danger caused by the situation or object.

People with a phobia:

There are several types of phobias and phobia-related disorders:

Specific Phobias (sometimes called simple phobias): As the name suggests, people who have a specific phobia have an intense fear of, or feel intense anxiety about, specific types of objects or situations. Some examples of specific phobias include the fear of:

Social anxiety disorder (previously called social phobia): People with social anxiety disorder have a general intense fear of, or anxiety toward, social or performance situations. They worry that actions or behaviors associated with their anxiety will be negatively evaluated by others, leading them to feel embarrassed. This worry often causes people with social anxiety to avoid social situations. Social anxiety disorder can manifest in a range of situations, such as within the workplace or the school environment.

Agoraphobia: People with agoraphobia have an intense fear of two or more of the following situations:

People with agoraphobia often avoid these situations, in part, because they think being able to leave might be difficult or impossible in the event they have panic-like reactions or other embarrassing symptoms. In the most severe form of agoraphobia, an individual can become housebound.

Separation anxiety disorder: Separation anxiety is often thought of as something that only children deal with; however, adults can also be diagnosed with separation anxiety disorder. People who have separation anxiety disorder have fears about being parted from people to whom they are attached. They often worry that some sort of harm or something untoward will happen to their attachment figures while they are separated. This fear leads them to avoid being separated from their attachment figures and to avoid being alone. People with separation anxiety may have nightmares about being separated from attachment figures or experience physical symptoms when separation occurs or is anticipated.

Social anxiety disorder (social phobia) involves high levels of anxiety, fear and avoidance of social situations due to feelings of embarrassment, self-consciousness and concern about being judged or viewed negatively by others.

A person with social anxiety disorder has significant anxiety and discomfort about being embarrassed, humiliated, rejected or looked down on in social interactions. People with this disorder will try to avoid the situation or endure it with great anxiety. Common examples are extreme fear of public speaking, meeting new people or eating/drinking in public. The fear or anxiety causes problems with daily functioning and lasts at least six months.

 

Causes

The causes of anxiety disorders aren't fully understood. Life experiences such as traumatic events appear to trigger anxiety disorders in people who are already prone to anxiety. Inherited traits also can be a factor.

Medical causes

For some people, anxiety may be linked to an underlying health issue. In some cases, anxiety signs and symptoms are the first indicators of a medical illness. If your doctor suspects your anxiety may have a medical cause, he or she may order tests to look for signs of a problem.

Examples of medical problems that can be linked to anxiety include:

·       Heart disease

·       Diabetes

·       Thyroid problems, such as hyperthyroidism

·       Respiratory disorders, such as chronic obstructive pulmonary disease (COPD) and asthma

·       Drug misuse or withdrawal

·       Withdrawal from alcohol, anti-anxiety medications (benzodiazepines) or other medications

·       Chronic pain or irritable bowel syndrome

·       Rare tumors that produce certain fight-or-flight hormones

Sometimes anxiety can be a side effect of certain medications.

It's possible that your anxiety may be due to an underlying medical condition if:

·       You don't have any blood relatives (such as a parent or sibling) with an anxiety disorder

·       You didn't have an anxiety disorder as a child

·       You don't avoid certain things or situations because of anxiety

·       You have a sudden occurrence of anxiety that seems unrelated to life events and you didn't have a previous history of anxiety
