Anxiety
What is it?
Anxiety is a type of mood disorder which involves two key elements: strong negative emotions and physical symptoms.
Fear vs. Anxiety
We have all experienced fear at some point in our lives. Fear is a useful emotion-- it is a biological adaptation that keeps us safe from danger. While fear is an emotional reaction to present danger, anxiety is anticipation of future harm. Anxiety is not problematic in itself. Often, anxiety helps ready our bodies to perform well, like in sporting events, or it can encourage us to prepare for an upcoming test. Anxiety is problematic when it becomes debilitating and begins to affect the quality of our daily life.
What's Going On In the Brain?

Anxiety triggers the fight/ flight response in our brains. This cues our adrenal glands to release chemicals called adrenalin and noradrenalin. These chemicals send messages out into our bodies to get us ready to face danger. Our pulse quickens, and the strength of our heart beat increases. Our lungs take in deeper breaths at a quicker pace to send oxygen out to our muscles. We begin to sweat and pupils dilate to let in more light. Our digestive system and salivation decrease in activity. Our muscle tense to ready for what's to come. Our overall metabolism increases, which uses up a large amount of energy.

Types of Anxiety Disorders
There are multiple types of anxiety disorders. Children may only experience one of these types of anxiety disorder. However, it is common that if a child is diagnosed with one anxiety disorder, they will be diagnosed with an additional anxiety disorder as well.
Separation Anxiety Disorder (SAD)
This is one of the most common anxiety disorders experienced by children. Children experiencing SAD will display age-inappropriate and disabling distress when separated from parents or other people they are attached to. Because of this, these children will often refuse to go to school as it requires them to be apart from a parent.
Specific Phobias
Children with specific phobia will display extreme fear of a particular objects that are neither dangerous nor harmful. Often times these phobias are of certain animals, which most scientists believe is a result of biological predispositions.
Social Anxiety Disorder
Social anxiety involves a fear of being the centre of attention or of doing something embarrassing in public. The fear of performing in front of others as well as the fear of interacting with others may occur simultaneously or separately.
Selective Mutism
If a child experiences selective mutism, they will not speak in specific social situations, while they will speak in other settings. This is the least common anxiety disorder experienced by children. Often times Selective Mutism will occur simultaneously with Social Anxiety Disorder.
Panic Disorder & Agoraphobia
Those who suffer from panic attacks will experience sudden burst of intense fear accompanied with physical symptoms. Panic attacks occur unexpectedly, and leave individuals fearfully anticipating the next one. Agoraphobia, the fear of certain situation often having to do with being unable to escape or find help if needed, often accompanies these panic attacks.
Generalized Anxiety Disorder (GAD)
Youth who experience Generalized Anxiety Disorder experience chronic worry. Unlike the above mentioned Anxiety Disorders which are linked to specific scenarios or objects, Generalized Anxiety are often in an elevated state of worry about many different things daily. These individuals often cannot cope with uncertainty.
Obsessive-Compulsive Disorder (OCD)
While OCD is not a subtype of Anxiety Disorder, it is quite similar and has many overlapping symptoms. When a child experiences OCD, they experience intrusive and repetitive obsessions, which induce anxiety. These obsessions result in ritualized behaviours, compulsions, to cope with the stress produced by the obsession.
Post-Traumatic Stress Disorder (PTSD)
Post-Traumatic Stress may occur after a child has experienced a traumatic event. The child will then re-experience this trauma through recurring thoughts, or dreams. Sometimes, Survival Guilt may be experienced in conjunction with PTSD.
Acute Stress Disorder
Similarly to PTSD, Acute Stress Disorder takes place after a child has experienced a traumatic experience. The difference though, is that Acute Stress Disorder takes place soon after the trauma, while PTSD is experienced after four weeks have passed since the event.
