Anxiety Disorders: Types, Symptoms, and When to Get Help

Anxiety is one of the most common mental health conditions in Canada, affecting an estimated 5% of the population according to the Canadian Mental Health Association. While occasional anxiety is a normal response to stress, anxiety disorders involve persistent, excessive worry that interferes with daily functioning. The main types of anxiety disorders include generalized anxiety disorder (GAD), characterized by chronic worry about everyday matters; social anxiety disorder, involving intense fear of social situations; panic disorder, marked by sudden, intense episodes of fear with physical symptoms; and specific phobias, which are intense fears of particular objects or situations. Common symptoms across anxiety disorders include persistent worrying or dread, difficulty concentrating, sleep disturbances, muscle tension, irritability, and avoidance of triggering situations. Anxiety disorders are treatable. First-line treatments in Canada include cognitive behavioural therapy (CBT), which has strong evidence supporting its effectiveness, and medications such as SSRIs (e.g., sertraline, escitalopram) or SNRIs (e.g., venlafaxine). Many patients benefit from a combination of therapy and medication. If anxiety is interfering with your work, relationships, or daily activities, it is worth speaking with a healthcare provider. You do not need a referral to speak with a physician about anxiety - telehealth consultations can provide an initial assessment and, if appropriate, a treatment plan or referral. *This article is for informational purposes only.*
