Anxiety Disorder

Anxiety is a psychological and physiological state characterized by cognitive, somatic, emotional, and behavioural components. These components combine to create an unpleasant feeling that is typically associated with uneasiness, fear, or worry.

Anxiety is a generalized mood state that occurs without an identifiable triggering stimulus. As such, it is distinguished from fear, which occurs in the presence of an external threat. Additionally, fear is related to the specific behaviours of escape and avoidance, whereas anxiety is the result of threats that are perceived to be uncontrollable or unavoidable.

Anxiety is a normal reaction to stress. It may help a person to deal with a difficult situation, for example at work or at school, by prompting one to cope with it. When anxiety becomes excessive, it may fall under the classification of an anxiety disorder.

Obsessive Compulsive Disorder

Obsessive-compulsive disorder (OCD) is an illness that affects thoughts and actions and is believed to be rooted in a biochemical imbalance of the brain. OCD is classified as an anxiety disorder in the Diagnostic and Statistical Manual (DSM-IV) published by the American Psychiatric Association.

This puzzling illness is characterized by recurrent and disturbing thoughts (called obsessions) and/or repetitive, ritualized behaviours that the person feels driven to perform (called compulsions). Obsessions can also take the form of intrusive images or unwanted impulses. The majority of patients have both obsessions and compulsions, but a minority (about 20 percent) have obsessions alone or compulsions alone (about 10 percent). The person with OCD usually tries to actively dismiss the obsessions or neutralize them by engaging in compulsions or avoiding situations that trigger them. In most cases, compulsions serve to alleviate anxiety. However, it is not uncommon for the compulsions themselves to engender anxiety, especially when they become very demanding.

A hallmark of OCD is that the person recognizes that her thoughts or behaviours are senseless or excessive. However, the drive can be so powerful that the person caves in to the compulsion even though she knows it makes no sense.

Social Phobia

Social anxiety disorder, also known as social phobia, involves intense fear of certain social situations – especially situations that are unfamiliar or in which you’ll be watched or evaluated by others. These social situations may be so frightening that you get anxious just thinking about them or go to great lengths to avoid them.

Underlying social anxiety disorder is the fear of being scrutinized, judged, or embarrassed in public. You may be afraid that people will think badly of you or that you won’t measure up in comparison to others. And even though you probably realize that your fears of being judged are at least somewhat irrational and overblown, you still can’t help feeling anxious.

Although it may feel like you’re the only one with this problem, social anxiety disorder is actually quite common. Many people struggle with these fears. But the situations that trigger the symptoms of social phobia can be different.

Some people experience anxiety in most social and performance situations, a condition known as generalized social anxiety disorder. For other people with social phobia, anxiety is connected with specific social situations, such as speaking to strangers, eating at restaurants, or going to parties. The most common specific social phobia is fear of public speaking or performing in front of an audience.
