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:
Feeling restless, wound-up, or on-edge
Being easily fatigued
Having difficulty concentrating; mind going blank
Having muscle tension
Difficulty controlling feelings of worry
Having sleep problems, such as difficulty falling or staying asleep, restlessness, or unsatisfying sleep
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:
Heart palpitations, a pounding heartbeat, or an accelerated heartrate
Trembling or shaking
Sensations of shortness of breath, smothering, or choking
Feelings of impending doom
Feelings of being out of control
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).
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:
May have an irrational or excessive worry about encountering the feared object or situation
Take active steps to avoid the feared object or situation
Experience immediate intense anxiety upon encountering the feared object or situation
Endure unavoidable objects and situations with intense anxiety
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:
Specific animals, such as spiders, dogs, or snakes
