Anxiety Disorders
Anxiety disorders are the world's most common mental disorders. They are characterized by excessive fear or worry that is difficult to control, interferes with daily activities, and lasts for at least several months.
Generalized Anxiety Disorder
GAD is a condition in which a person worries excessively and has a hard time controlling it. Those with GAD tend to expect disaster and can't stop worrying about health, money, family, work, school, or other things. Daily life becomes a near-constant state of worry, fear, and dread, making it difficult to do routine things at work or school, socially, and in relationships. Healthcare providers typically diagnose GAD when worrying happens on most days and for at least 6 months.
Symptoms include restlessness, extreme tiredness (fatigue), trouble focusing, irritability, increased muscle tension, and trouble sleeping. It is often accompanied by physical symptoms such as headaches, muscular tension, restlessness, heart palpitations, and stomach upset.
One of the most prevalent misconceptions is that GAD is simply another term for everyday stress or worry. Unlike normal stress, which usually resolves once the stressful event has passed, people with GAD remain in a heightened state of anxiety for weeks, months, or even years. Another harmful stereotype is that only weak, overly sensitive, or fragile people suffer from the disorder. In reality, GAD can affect anyone, regardless of their strength, resilience, or personality, and many people with GAD are high-achieving, successful individuals. A further misconception is that GAD can be completely "cured" — in reality, it requires ongoing management and treatment to keep symptoms at bay.
Experts don't know the exact causes of GAD. Several things — including genetics, brain chemistry, and environmental stresses — appear to contribute to its development. GAD has been linked to problems with certain nerve cell pathways that connect brain regions involved in thinking and emotion. Experiencing traumatic events, child abuse, or being in a highly stressful environment might also trigger GAD. Long-term stress from personal circumstances or work-related issues can be a significant factor.
Common medication options include SSRIs (such as escitalopram, paroxetine, or sertraline) and SNRIs (such as duloxetine and venlafaxine). Alongside medical treatment, people can make small lifestyle changes — reducing caffeine, getting enough sleep, eating healthy, and staying physically active — and practice relaxation techniques such as yoga, meditation, or mindfulness. Treatment most often includes a combination of medication and cognitive behavioral therapy (CBT).
If left untreated, studies show that GAD is often a chronic illness with symptoms that tend to wax and wane across the lifespan. Seek professional support if worry is occupying more than an hour a day, is difficult to control, is causing significant distress, or is interfering with work, relationships, or daily tasks. If you are at any point feeling overwhelmed or at risk of harming yourself, tell your provider; if you're in immediate danger, contact 911 or your local emergency services.
Social Anxiety Disorder
Social anxiety disorder (formerly known as social phobia) is a condition that causes an intense and ongoing fear of others watching or judging you. Specific or multiple social situations trigger fear and anxiety, and a core feature is the fear of being judged, rejected, and/or humiliated. It's different from being shy or introverted. The diagnosis of social anxiety disorder requires that the symptoms persist for six months or longer.
Symptoms include blushing, sweating, trembling, nausea, an increased heart rate, and the mind "going blank." These symptoms can greatly disrupt daily life, such as school, work, and relationships. People may worry about engaging in social situations for weeks before they happen, and sometimes end up avoiding places or events that cause distress or generate feelings of embarrassment.
Social anxiety is often misunderstood as simple shyness — but while the two can look similar, they are not the same thing. Many people with this condition do not seek diagnosis or treatment, believing it is just a part of their personality. Another misconception is that social anxiety is purely psychological; in fact, people often experience physical symptoms that mimic illness, such as throat tension or difficulty swallowing — genuine bodily reactions that are part of the fight-or-flight response.
Researchers don't know the exact cause of social anxiety disorder, but think many factors contribute to it, including genetics, brain chemistry, and life experiences. Women tend to have social anxiety disorder more often than men.
here are effective treatment options for social anxiety disorder. Exposure therapy is usually effective, gradually helping people get used to anxiety-provoking situations and grow comfortable in them. Medications such as SSRIs and beta-blockers are also commonly used. Many people with this condition do not seek treatment, and may instead seek help for related issues, such as depression or substance use.
A person may experience social anxiety disorder for many years without proper diagnosis and treatment. Some people with the condition experience loneliness, depression, or suicidal thoughts, stemming from the isolation that the condition can cause. Seek additional support if fear of social situations is causing you to withdraw from work, relationships, or daily activities, or if you are relying on alcohol or substances to cope.
Panic Disorder
Most people experience panic attacks once or twice in their lives. Panic disorder occurs when you experience recurring, unexpected panic attacks, often without a clear cause. Panic disorder is defined by at least one month of persistent fear about panic attacks (or their effects) reoccurring.
Panic attacks may include physical symptoms such as shortness of breath, a pounding heart, or chest pain. People often think they are having a heart attack and seek treatment in a hospital emergency room. Other symptoms include chronic anxiety that interferes with daily life, difficulty concentrating, extreme irritability, and sleep problems. Panic attacks can also cause a fear of leaving home (agoraphobia).
Many people with panic disorder first seek treatment at the emergency room because the panic attack often feels like a heart attack — a major misconception that panic symptoms are always a medical emergency. Although panic attacks are extremely uncomfortable, they are not physically harmful, though they can take a toll on mental health. Another misconception is that panic attacks are a sign of weakness or that people can simply push through them without treatment. Many people don't seek treatment because they think the symptoms aren't bad enough, but getting treatment is important to prevent related problems including depression, other anxiety disorders, and substance use disorder.
For many people, the first panic attack may occur at a stressful time — during a serious illness or accident, the loss of a relationship, or separation from family. A woman may have her first panic attack after giving birth. Genetics, temperament, and an overactive fight-or-flight response also appear to play roles.
The goal of treatment is to help you function well during everyday life. Using both medicines and talk therapy works best. CBT can help you understand panic attacks, recognize and replace thoughts that cause panic, manage stress and relax when symptoms occur, and practice in real-life situations to overcome fears. SSRIs help balance neurotransmitters in the brain, while benzodiazepines can provide short-term relief from acute symptoms.
Seek emergency medical care if you have chest pain, trouble breathing, or lose consciousness. Call your healthcare provider if panic attacks cause chronic anxiety that interferes with daily life, symptoms that last longer than 15 minutes, or a growing fear of leaving your home.
Obsessive-Compulsive Disorder (OCD)
OCD is a long-lasting disorder in which a person experiences uncontrollable and recurring thoughts (obsessions), engages in repetitive behaviors (compulsions), or both. People with OCD have time-consuming symptoms that can cause significant distress or interfere with daily life. The obsessions and compulsions of OCD are ego-dystonic — people with OCD are distressed by the content of their intrusive thoughts and would truly prefer not to have them or perform the compulsions.
Common obsessions include fears about contamination, harm, symmetry, or taboo thoughts. Common compulsions include checking, counting, cleaning, and arranging. Symptoms would usually be considered OCD when you can't control your thoughts or behaviors even when you know they are excessive, spend at least one hour a day on these thoughts or behaviors, and have significant problems in your daily life because of them.
More than two-thirds of the public cannot accurately identify OCD. This misunderstanding results in stigma, misuse of the term in casual conversation, and delays in diagnosis and treatment — it takes an average of seven years for an individual to receive an accurate OCD diagnosis. A widespread myth is that OCD is simply about being neat or liking things organized. In reality, OCD involves profound distress and can revolve around themes completely unrelated to cleanliness, such as harm, religion, or relationships. Misdiagnosis and underdiagnosis are largely due to misconceptions about OCD, both by the public and among health care providers.
The cause of OCD is unknown. Factors such as genetics, brain biology and chemistry, and environment may play a role. People with a first-degree relative who has OCD are at higher risk, especially if the relative developed OCD as a child or teen. Imaging studies have shown that people with OCD have differences in certain parts of the brain.
The most effective treatment for OCD is exposure and response prevention (ERP) therapy, sometimes alongside medication. ERP involves gradually exposing you to your fears or obsessions. If severe OCD does not get better with these treatments, a provider may suggest repetitive transcranial magnetic stimulation (rTMS).
Seek help when obsessions or compulsions are consuming more than an hour a day, causing significant distress, or interfering with relationships, work, or school. People with OCD may not tell their health care provider about their obsessions and compulsions out of fear of judgment — but treatment helps many people, even those with the most severe forms of OCD. If you disclose scary intrusive thoughts to a provider, note that these thoughts are often misinterpreted — a specialist familiar with OCD is best positioned to assess them accurately.
Post-Traumatic Stress Disorder (PTSD)
PTSD is a condition that can develop after a person experiences or witnesses a traumatic event. Anyone can develop PTSD at any age, including combat veterans and people who have experienced or witnessed physical or sexual assault, abuse, an accident, a disaster, a terror attack, or other serious events. People who have PTSD may feel stressed or frightened even when they are no longer in danger.
Symptoms fall into four groups: intrusion (e.g., flashbacks), avoidance, negative changes in mood or thinking, and arousal or reactivity. Symptoms must last longer than one month and cause serious problems in daily life, such as at work, school, or in relationships. Symptoms usually start soon after the traumatic event, but sometimes may not appear until months or years later, and may come and go over many years.
One of the most common myths is that PTSD only impacts veterans. In reality, many different experiences can lead to PTSD, including being placed in foster care, the sudden death of a loved one, a serious physical health concern, or sexual assault. Another myth is that anyone who experiences a traumatic event will have PTSD — in fact, if a person receives proper support at the time of the event, they may navigate it without developing PTSD. A third misconception, perpetuated by media portrayals, is that PTSD makes people inherently violent. Most individuals with PTSD are more likely to withdraw or experience anxiety rather than exhibit aggression.
The nature of the event experienced can affect the chances of developing PTSD. Experiencing ongoing or repeated potentially traumatic events, developing a serious physical injury during the event, or witnessing harm to others can all increase risk. Receiving social support following potentially traumatic events can reduce the risk.
PTSD treatment often includes therapy and medications, and many people benefit from using both together. Types of therapy include trauma-focused cognitive behavioral therapy (CBT), which helps notice unhelpful thoughts linked to the experience and replace them with healthier ones. Psychological interventions can be delivered to individuals or groups, in person or online, and some may also be accessed through self-help manuals, websites, and apps.
If symptoms last longer than four weeks, cause you great distress, or interfere with work or home life, you may have PTSD and should seek professional evaluation. Seek immediate support if you are experiencing thoughts of self-harm. If anxiety starts to cause problems in everyday life — such as at school, at work, or with friends and family — it's time to seek professional help.
Specific Phobia Disorder
Specific phobias involve persistent, unrealistic, intense anxiety about and fear of specific situations, circumstances, or objects. Specific phobias are common anxiety disorders that affect about 8% of women and 3% of men yearly. The most common specific phobias include fear of animals (zoophobia), fear of heights (acrophobia), and fear of thunderstorms.
Specific phobias are characterized by extreme and unreasonable fear toward objects or conditions that do not pose real danger, manifesting as a racing heart, shortness of breath, dry mouth, incoherent speech, sweating, or dizziness. The fear response is disproportionate to the actual threat, and the person will go out of their way to avoid contact with the feared object or situation.
A common misconception is that phobias are simply extreme versions of everyday fears that people could overcome if they just tried harder. Children with specific phobias are not "attention-seeking" or "overly dramatic" — they are genuinely overwhelmed by their fear. Well-meaning parents often rearrange life to protect their child, but this teaches the child "I can't handle this," and the phobia quietly grows. Another myth is that phobias are rare — in fact, they are among the most common anxiety disorders. Some people do well without treatment because the thing they fear is easy to avoid, but if situations or objects are commonly encountered, treatment is often needed.
There is no known single cause, although phobias seem to run in families and are found slightly more often in women. Causes can include a direct traumatic experience with the feared object, witnessing someone else's fearful reaction, or being repeatedly warned about a danger. Brain chemistry and genetics also appear to contribute.
