What Is Agoraphobia? Symptoms, Causes, Diagnosis, Treatment, and Prevention

Agoraphobia is an anxiety disorder characterized by an intense fear about any place or situation from which escape might be difficult, or where help might not be available if a problem occurs.

People with agoraphobia often fear helplessness in situations in which strong anxiety, panic, or fear of an embarrassing situation can develop, and they typically don’t feel comfortable or safe in public places — especially places that are crowded.

This fear may eventually cause a person with agoraphobia to want to stay at home, indoors, at all times. If they do leave the house, they may always need to have one particular person accompanying them.

In ancient Greece, “agora” meant “the marketplace,” so agoraphobia is the term used to name the fear of being in a large, open, public space — although the phobia is not of the space itself, but of the potential difficulty in fleeing if things go awry.

Signs and Symptoms of Agoraphobia

People with agoraphobia may feel:

  • Afraid of spending time alone, of places where escape is difficult, or of losing control in public
  • Detached or isolated from other people
  • Helpless
  • As if their body or their environment isn’t real (“derealization”)

Agoraphobia may also lead people to depend on others (to handle their financial obligations, for example), to have a volatile temper, or to stay indoors for long periods of time.

Agoraphobia can also lead to panic attacks or panic-like symptoms, which may include: (1,2,3)

  • Nausea or other gastrointestinal issues, such as diarrhea
  • Rapid heartbeat
  • Chest pain or discomfort
  • Dizziness or light-headedness
  • Feeling short of breath
  • Sweating and trembling
  • Facial flushing
  • A feeling of choking
  • Numbness or “pins and needles” sensations
  • Feelings of unreality or being detached from oneself

Causes and Risk Factors of Agoraphobia

As with other anxiety disorders, it’s not always clear what causes people to develop agoraphobia.

Several factors may make some people more likely to develop the condition, such as:

  • Genetics Agoraphobia and other anxiety disorders sometimes run in families. Some of this relationship could be learned behavior, but some may be related to genetics. (2)
  • Brain Structure Differences in the areas of the brain that regulate fear and anxiety may contribute to the condition. (4)
  • Traumatic Events Physical or sexual trauma during childhood can play a role as well. (4)

How Is Agoraphobia Diagnosed?

Your doctor will make a diagnosis on the basis of your signs and symptoms, and may also conduct a physical exam or order blood tests to rule out other possible causes of your symptoms.

According to the American Psychiatric Association, to be diagnosed with agoraphobia, you need to experience intense fear that you won’t be able to leave in the event of a panic attack or a possibly embarrassing event like fainting, in at least two of the following five situations: (5)

  • Using public transportation
  • Being in open spaces, such as parking lots, bridges, and malls
  • Being in theaters or other enclosed spaces
  • Waiting in line or being in a crowd
  • Being outside of your home alone

These situations must also be ones that are avoided, gone through only with the presence of another person, or endured with intense fear. And these feelings and behaviors must go on for six months or more.

Prognosis of Agoraphobia

With proper treatment, often a combination of psychotherapy and medication, many people can eventually manage their anxiety, in order to feel and function better. (6)

Duration of Agoraphobia

Agoraphobia tends to be persistent and chronic. Without early interventions, agoraphobia can become more severe and more difficult to treat. But effective treatment can help you function with agoraphobia. (1)

Treatment and Medication Options for Agoraphobia

Agoraphobia and other anxiety disorders are generally treated with psychotherapy, such as cognitive behavioral therapy (CBT). Medications, such as certain antidepressants, are sometimes used in severe cases or when there is another mental health condition accompanying the agoraphobia.

CBT — which has been shown to be effective for treating a variety of psychological disorders — helps people identify, understand, and change the thoughts and behaviors that contribute to their condition. It’s thought that this therapy may be more cost-effective in the long run, and better tolerated, than medication. Experts sometimes say that CBT can take 10 to 20 sessions to work, based on available research studies, but it may also take longer. (1)

One type of CBT is called exposure therapy. Exposure therapy is often used to treat certain phobias. It involves gradually facing feared situations or objects, causing you to become less fearful over time. (7)

You may also be able to receive CBT over the phone or online from a licensed therapist. Research on the efficacy of this “remote” therapy is still early, but some studies suggest it may be just as helpful as going into your therapist’s office — and one study found that virtual therapy was very effective for treating panic disorders and agoraphobia. (8

If you have other, related disorders in addition to agoraphobia, or are not getting completely better with therapy, your doctor may also prescribe antidepressants to help treat the condition as well as your panic symptoms.

The kind of antidepressants that are most often prescribed are selective serotonin reuptake inhibitors, or SSRIs. These drugs help make serotonin become more available to the brain.

Examples of SSRIs include:

  • fluoxetine (Prozac)
  • citalopram (Celexa)
  • sertraline (Zoloft)
  • escitalopram (Lexapro)

Anti-anxiety medications called benzodiazepines may also be prescribed, though the use of these drugs for agoraphobia is controversial. Some believe they are good short-term tools for people whose symptoms are so severe that they cannot carry out simple functions, such as leaving their homes; others note that the use of these medications can interfere with therapy, which relies on a person experiencing some discomfort and working through it.

Some commonly used benzodiazepines are:

  • clonazepam (Klonopin)
  • alprazolam (Xanax)

Benzodiazepines help relieve anxiety by enhancing the activity of a neurotransmitter in the brain and generating a sedative effect. They work quickly — often within one hour or several hours.

Because they work so quickly, and because people taking them can build up a tolerance that leaves them needing higher doses to feel better, people can become addicted to them. So doctors often will prescribe them for very short periods of time. (7)

If you stop taking them suddenly, withdrawal symptoms may occur (which can be dangerous), so it’s important to follow your doctor’s instructions for tapering off your medication.

Prevention of Agoraphobia

According to the National Institutes of Health (NIH), early treatment of agoraphobia symptoms may prevent the disorder from developing. (1)

If you recognize mild early signs or behaviors consistent with agoraphobia, you may be able to act before the fear becomes overwhelming. For instance, if you start to feel anxious about feeling safe in a place where the actual risk of harm is low, you might face and reduce those fears by going to that place repeatedly. (3)

Complications of Agoraphobia

Severe agoraphobia can be incredibly limiting, interfering with routine, daily activities, such as going to work or school, seeing friends and family, or even leaving the house to run errands. (3)

Agoraphobia is associated with an increased risk of developing major depressive disorder, persistent depressive disorder (dysthymia), and substance use disorders. (9)

Research and Statistics: Who Has Agoraphobia?

Because agoraphobia has only become a formal stand-alone diagnosis relatively recently (previously being considered an aspect of panic disorder), the data vary on how prevalent it is. The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V), which classified agoraphobia as its own diagnosis, notes that approximately 1.7 percent of the population has agoraphobia. (9)

The National Institute of Mental Health (NIMH) reports similar numbers, with a lifetime prevalence is 1.3 percent. The NIMH reports that 0.9 percent of the adult population in the United States experiences agoraphobia in a given year.  (10)

Among adults with agoraphobia in the past year, an estimated 40.6 percent were seriously impaired by agoraphobia. Impairment was moderate for 30.7 percent, and 28.7 percent had mild impairment. (10)

The mean age of diagnosis of agoraphobia is in the mid-to-late twenties. (9) And women are diagnosed with it more frequently than men. (3)

COVID-19 and Agoraphobia

For some people with agoraphobia, the measures of quarantining and social distancing undertaken to limit the spread of the novel coronavirus, may have come as a relief. But for others, especially those who also have panic disorder, life during the pandemic has likely exacerbated symptoms, or caused regression in people who were making progress in treating their condition. (11)


My Anxiety Disorder and COVID-19: Please Don’t Tell Me to Calm Down

And while the data isn’t yet fully known, it’s possible that reaction to the pandemic has caused agoraphobia to develop in people who haven’t previously had the condition. As restrictions across the country were lifted or relaxed, anxiety about leaving the house and feeling safe in more crowded public spaces may have increased in certain people, especially among those at risk for developing agoraphobia. But it can be challenging to tell the difference between agoraphobia and anxiety due to the coronavirus, notes the Cleveland Clinic. (12)

Related Conditions and Causes of Agoraphobia

Agoraphobia is often associated with panic disorder, an anxiety disorder in which a person experiences recurrent panic attacks. These attacks are intense, sudden bouts of fear or terror that develop when no actual danger is present.

About 1 in 3 people with panic disorder develop agoraphobia. (6)

People with panic disorder live in fear of having a panic attack, which can lead them to avoid certain places or situations where panic is likely. Some people with panic disorder, fearing the physical sensations of panic, may try to avoid all situations where it would be difficult to escape in the event of an attack, leading to agoraphobia. 

According to researchers, panic disorder with agoraphobia tends to be chronic, while panic disorder without agoraphobia tends to come and go in phases. (14) Experts have also noted that panic disorder with agoraphobia often coexists with obsessive compulsive disorder (OCD). (15)

It’s possible to have agoraphobia without experiencing full-blown panic attacks. You may experience feelings of fear or anxiety, but these won’t progress into a panic attack. This condition is sometimes called primary agoraphobia.
