What Is an Anxiety Disorder?

An anxiety disorder is a type of mental disorder where a person experiences uncontrollable and sometimes extreme anxiety.

What separates “normal” anxiety and an anxiety disorder is that for those who have an anxiety disorder, their anxiety level often impacts their daily lives.

If you are unsure if you have an anxiety disorder, you can ask yourself the following questions:

  • Am I experiencing physical signs of anxiety, such as excessive sweating and a rapid heartbeat?
  • Is my anxiety interfering with my ability to function?
  • Am I unable to control how I react to certain situations?
  • Do I often overreact when something triggers my anxiety or emotions?

If you answered yes to one or more of the above questions, you might have an anxiety disorder. You should talk to your healthcare provider or a licensed mental health professional as soon as possible.

Anxiety disorder is an umbrella term for various anxiety-based mental health disorders.

Some of the more common anxiety disorders include:

  • Generalized Anxiety Disorder
  • Obsessive Compulsive Disorder
  • Panic Disorder
  • Post Traumatic Stress Disorder
  • Social Anxiety Disorder

Generalized Anxiety Disorder

Generalized Anxiety Disorder (GAD) is characterized by experiencing anxiety or dread to the point where it can interfere with a person’s everyday life. This anxiety or worry can last weeks, months, or even years.

Some common symptoms of Generalized Anxiety Disorder include:

  • Irritability
  • Difficulty concentrating
  • Feeling restless or on edge
  • Sleep problems
  • Unexplained headaches, stomachaches, muscle aches, and pains
  • Having trouble controlling feelings of worry
  • Fatigue

Obsessive Compulsive Disorder

Obsessive Compulsive Disorder (OCD) is an anxiety disorder where someone might live in a chronic state of anxiety due to obsessions over behavior, routine, and thoughts.

They may also exhibit notably compulsive behaviors, such as rituals or repetitive behaviors (e.g., knocking, tapping, hand washing).

The loop of obsessions leading to compulsions can cause a constant cycle of anxiety.

Examples of OCD include:

  • Unpleasant thoughts or images
  • Fear of losing or misplacing things
  • Constantly wondering if you did something or did it right
  • Repeatedly washing your hands, showering, brushing your teeth, etc
  • Counting the same thing repeatedly
  • Constantly checking locks or appliances
  • Ordering items in a specific order or in a particular way

Panic Disorder

Frequent and unexplained panic attacks characterize panic disorder. Someone experiencing a panic attack will likely experience extreme discomfort, fear, and a sense of losing control.

Additional symptoms that are common with a panic disorder include:

  • Chest pain
  • Sweating
  • Pounding or racing heartbeat
  • Trembling
  • Actively avoiding certain situations, places, or behaviors to try and prevent a panic attack
  • Constant worry about when the next panic attack might happen

Post Traumatic Stress Disorder

Post Traumatic Stress Disorder (PTSD) is a mental health condition that develops after experiencing a traumatic event. Events that cause PTSD can be dangerous, life-threatening, shocking, or scary.

Reliving or even thinking about the event or events can lead to extreme feelings of anxiety and dread.

Symptoms of PTSD include:

  • Trying to avoid anything that might trigger memories of the traumatic event
  • Constantly being on edge
  • Experiencing negative thoughts or feelings such as guilt, sadness, or numbness
  • Suicidal thoughts or actions
  • Having flashbacks or dreams from the event

Social Anxiety Disorder

Someone who has a social anxiety disorder may experience anxiety and dread at just the thought of having to be in social situations. Others may have more extreme social phobia (e.g., agoraphobia) and become unable to leave their homes without extreme mental distress.

These feelings might be so severe that they actively avoid everyday events like going to work or school.

Some symptoms associated with social anxiety disorder include:

  • Excess sweating
  • Trembling
  • Stomachaches
  • Pounding or racing heart
  • Rigid posture
  • Speaking very softly or sometimes not at all (i.e., selective mutism)

  • Generalized Anxiety Disorder: 2%

Anxiety Disorder Causes and Risk Factors

Just because someone experiences anxiety doesn’t automatically mean they currently have or will develop an anxiety disorder. However, certain risk factors and causes can increase the chances of developing an anxiety disorder.

Below are some common causes and risk factors associated with anxiety disorder:

  • Genetics: Someone who has anxiety disorders run in their family is more likely to develop one themselves
  • Substance use and addiction: Using and abusing certain illicit substances can lead to the development of an anxiety disorder
  • Medical conditions: Certain medical conditions can lead to the worsening of anxiety symptoms, including lung, thyroid, and heart conditions
  • Brain chemistry: Researchers have found that a chemical imbalance in the brain can lead to anxiety disorders
  • Environmental stress: Traumatic events such as abuse, violence, and death of a loved one can lead to an anxiety disorder, specifically PTSD
  • Low self-esteem: Negative perceptions of yourself can lead to an anxiety disorder, specifically social anxiety disorder

Anxiety Disorders and Addiction

Many individuals who have an anxiety disorder don’t seek mental health treatment for their condition. They might be too afraid or ashamed to seek help or unsure how to get the help they need.

In those situations, it is not uncommon for someone with an anxiety disorder to turn to drugs or alcohol as a way of self-medicating to feel better or even normal again.

While in the short-term, self-medicating might seem like a solution to their anxiety disorder issues, it can make their anxiety disorder symptoms worse and lead to addiction.

Those currently battling addiction might also experience symptoms associated with anxiety disorders as a side effect of their substance use and abuse.

Treating Anxiety Disorders

While there is no known cure for anxiety disorder, it is treatable. The most effective treatments for anxiety disorders are psychotherapy, medication, and support groups.


Psychotherapy, also known as talk therapy, is a popular treatment method for those who have an anxiety disorder because it can help get to the bottom of what led to the development of the condition in the first place.

Psychotherapy also teaches healthier and more productive ways of dealing with these thoughts, feelings, and triggers in the future.

Forms of psychotherapy commonly used when treating anxiety disorders include:


Doctors may prescribe various medications to help ease some anxiety disorder symptoms.

Some of these medications include:

  • Antidepressants
  • Benzodiazepines
  • Beta-blockers
  • Antipsychotics
  • Anticonvulsants
  • Buspirone
  • Anti-anxiety medications

Support Groups

Many people struggling with mental health conditions such as anxiety disorders might feel isolated or that nobody around them can understand what they are going through.

For those people, being around others who not only know what they are going through but have similar experiences can be a great way to work through the issues associated with their anxiety disorder.

Organizations such as the Anxiety and Depression Association of America (ADAA) offer support groups for people with an anxiety disorder both in person and virtually.
