Anxiety Disorders

What exactly is “anxiety”? From phobias to PTSD

Panic attacks
Social phobia
Regulating stress hormones

Generalized Anxiety Disorder

Generalized Anxiety Disorder (GAD) is a mental health condition characterized by excessive, persistent, and uncontrollable worry about everyday situations. This worry often interferes with daily functioning and can cause physical symptoms such as fatigue, irritability, and muscle tension. GAD affects approximately 3.1% of the U.S. population, making it a prevalent mental health concern.

The symptoms of GAD can vary from person to person, but typically include restlessness, difficulty concentrating, and sleep disturbances. Treatment options for GAD often involve a combination of medication and psychotherapy. Selective serotonin reuptake inhibitors (SSRIs) and benzodiazepines are commonly prescribed medications for managing GAD symptoms. Cognitive-behavioral therapy (CBT) is a widely used psychotherapeutic approach that helps individuals identify and change negative thought patterns and behaviors.


An example of GAD might be a person who constantly worries about their job performance, even when they have no reason to believe they are underperforming. This individual may experience difficulty sleeping, irritability, and muscle tension as a result of their excessive worry.

Panic Disorder

Panic disorder is a type of anxiety disorder characterized by recurrent, unexpected panic attacks. These attacks are sudden episodes of intense fear that trigger severe physical reactions, such as a rapid heartbeat, shortness of breath, and dizziness. Panic disorder affects approximately 2-3% of the U.S. population and can significantly impair daily functioning.


The characteristics of panic disorder include the fear of having another panic attack and avoidance of situations that may trigger one. Cognitive-behavioral therapy (CBT) is a common treatment for panic disorder, as it helps individuals identify and change negative thought patterns and behaviors that contribute to panic attacks. Medications, such as antidepressants and benzodiazepines, may also be prescribed to manage symptoms.

An example of panic disorder might be a person who experiences sudden, intense episodes of fear while driving, even when there is no apparent danger. This individual may avoid driving altogether due to the fear of having another panic attack.


Phobias are irrational, excessive fears of specific objects, situations, or activities. They are a common type of anxiety disorder, affecting approximately 9.1% of the U.S. population. Some of the most common phobias include arachnophobia (fear of spiders), acrophobia (fear of heights), and claustrophobia (fear of enclosed spaces).

Treatment options for phobias often involve exposure therapy, a form of cognitive-behavioral therapy (CBT) that gradually exposes individuals to the feared object or situation in a controlled environment. This helps them learn to manage their fear and anxiety more effectively. Medications, such as beta-blockers and benzodiazepines, may also be prescribed to help manage symptoms during exposure therapy.


Systematic desensitization is another treatment option for phobias, which involves teaching relaxation techniques and gradually exposing the individual to the feared object or situation while they practice these techniques. This process helps to reduce the anxiety associated with the phobia over time.

Virtual reality therapy is an emerging treatment option for phobias, allowing individuals to confront their fears in a controlled, virtual environment. This approach has shown promise in treating various phobias, such as fear of flying and fear of public speaking.

Obsessive-Compulsive Disorder

Obsessive-Compulsive Disorder (OCD) is a mental health condition characterized by recurrent, unwanted thoughts (obsessions) and repetitive behaviors (compulsions) that individuals feel compelled to perform. OCD affects approximately 1.2% of the U.S. population.

Symptoms of OCD can vary widely but often include excessive handwashing, repeated checking of locks or appliances, and persistent, intrusive thoughts about harm or contamination. Treatment options for OCD typically involve a combination of medication and psychotherapy. Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed medications for managing OCD symptoms, while cognitive-behavioral therapy (CBT), specifically exposure and response prevention (ERP), is a widely used psychotherapeutic approach.

An example of OCD might be a person who feels compelled to wash their hands excessively due to an irrational fear of contamination. This individual may spend hours each day washing their hands, causing skin irritation and interfering with daily activities.


Post-Traumatic Stress Disorder

Post-Traumatic Stress Disorder (PTSD) is a mental health condition that can develop after experiencing or witnessing a traumatic event, such as a natural disaster, violent assault, or military combat. Approximately 3.5% of the U.S. population is affected by PTSD.


Symptoms of PTSD can include intrusive memories of the traumatic event, avoidance of reminders of the trauma, negative changes in mood and cognition, and increased arousal and reactivity. Treatment options for PTSD often involve a combination of medication and psychotherapy. Selective serotonin reuptake inhibitors (SSRIs) have been shown to effectively reduce the core symptoms of PTSD, including intrusive thoughts, nightmares, flashbacks, and hyperarousal. By modulating serotonin levels, these medications can help regulate emotional responses and diminish the intensity and frequency of distressing PTSD symptoms. Cognitive-behavioral therapy (CBT), eye movement desensitization and reprocessing (EMDR), and prolonged exposure therapy are widely used psychotherapeutic approaches.

An example of PTSD might be a military veteran who experiences flashbacks, nightmares, and severe anxiety related to their combat experiences. This individual may avoid situations that remind them of the trauma, such as loud noises or crowded places.

Social Anxiety Disorder

Social Anxiety Disorder (SAD), also known as social phobia, is a mental health condition characterized by an intense fear of social situations and a fear of being judged or embarrassed in front of others.

Symptoms of SAD can include excessive self-consciousness, avoidance of social situations, and physical symptoms such as blushing, sweating, and trembling. Treatment options for SAD often involve a combination of medication and psychotherapy. Selective serotonin reuptake inhibitors (SSRIs) and benzodiazepines are commonly prescribed medications for managing SAD symptoms. SAD is associated with alterations in serotonin activity, and SSRIs help restore a balance, potentially reducing the severity of symptoms. Cognitive-behavioral therapy (CBT) is a widely used psychotherapeutic approach that helps individuals identify and change negative thought patterns and behaviors.


An example of SAD might be a person who avoids attending social events due to an irrational fear of being judged or embarrassed. This individual may experience intense anxiety, even in relatively low-pressure social situations, such as ordering food at a restaurant.

Separation Anxiety Disorder

Separation Anxiety Disorder is a mental health condition characterized by excessive fear or anxiety about being separated from loved ones or familiar surroundings. While it is most commonly associated with children, adults can also suffer from it. The disorder can significantly impair daily functioning and affect both personal and professional relationships.

Symptoms of Separation Anxiety Disorder can include excessive distress when separated from loved ones, persistent worry about potential harm to loved ones, and reluctance to leave home or be alone.

Treatment options for Separation Anxiety Disorder often involve a combination of medication and psychotherapy. SSRIs have anxiolytic properties and can effectively reduce symptoms of anxiety associated with the disorder. These medications help regulate emotional responses, decrease excessive worry, and reduce the distress experienced during periods of separation from attachment figures.

In children, Parent-Child Interaction Therapy (PCIT) and family therapy may also be effective treatment options. These approaches focus on improving communication and attachment between the child and their caregivers, helping to reduce separation anxiety symptoms.

Adults with Separation Anxiety Disorder may benefit from individual therapy, group therapy, or couples therapy, depending on the specific circumstances and relationships involved.


Selective Mutism

Selective Mutism is a rare anxiety disorder that affects children, characterized by a consistent failure to speak in specific social situations where speech is expected, despite being able to speak in other situations. This disorder can significantly impair a child’s social and academic functioning.


Symptoms of Selective Mutism can include a refusal to speak in certain situations, such as at school or in public, while speaking normally at home or with close family members. Treatment options for Selective Mutism often involve a combination of medication and psychotherapy. Selective serotonin reuptake inhibitors (SSRIs) may be prescribed to help manage anxiety symptoms. Cognitive-behavioral therapy (CBT) and behavioral interventions, such as shaping and stimulus fading, are widely used psychotherapeutic approaches for treating Selective Mutism. Shaping is a behavioral technique used to teach and reinforce appropriate verbal behaviors. Stimulus fading involves gradually reducing the presence of anxiety-provoking stimuli or individuals while encouraging verbal communication.

Family involvement is crucial in the treatment of Selective Mutism, as parents and caregivers play a significant role in supporting the child’s progress. School-based interventions, such as working with teachers and school counselors, can also be beneficial in helping the child overcome their communication difficulties.

Anxiety and the Brain

The neurological basis of anxiety disorders involves complex interactions between various brain regions and neurotransmitter systems. Key neuroanatomic circuits supporting fear and anxiety include the amygdala, hippocampus, and prefrontal cortex. The amygdala, in particular, plays a central role in processing fear and anxiety-related information.

The amygdala receives sensory input from the environment and evaluates it for potential threats. When a threat is detected, the amygdala activates the body’s stress response, leading to the physical and emotional symptoms of anxiety. Dysregulation of the amygdala and its connections with other brain regions, such as the hippocampus and prefrontal cortex, has been implicated in the development and maintenance of anxiety disorders.

Neurotransmitters, such as serotonin, norepinephrine, and gamma-aminobutyric acid (GABA), also play a crucial role in modulating anxiety. Imbalances in these neurotransmitter systems can contribute to the development of anxiety disorders. Many medications used to treat anxiety disorders, such as SSRIs and benzodiazepines, work by targeting these neurotransmitter systems and restoring balance.

Anxiety Management Techniques

Various anxiety management techniques can help individuals cope with and reduce their anxiety symptoms. These techniques can be used in conjunction with medication and psychotherapy or as standalone strategies for managing mild to moderate anxiety.

Mindfulness and meditation practices, such as deep breathing exercises and progressive muscle relaxation, can help individuals become more aware of their anxiety symptoms and develop healthier coping strategies. Regular physical activity has also been shown to reduce anxiety levels, as exercise can help regulate stress hormones and promote the release of endorphins, which are natural mood elevators.


Cognitive restructuring is a technique used in cognitive-behavioral therapy (CBT) that involves identifying and challenging negative thought patterns that contribute to anxiety. By replacing these negative thoughts with more balanced and realistic perspectives, individuals can reduce their anxiety levels and improve their overall mental well-being.

Finally, establishing a consistent sleep schedule and practicing good sleep hygiene can help reduce anxiety symptoms, as inadequate sleep can exacerbate anxiety and stress.
