These physiological responses can actually help us to survive. However, sometimes we experience these physiological responses, like an increased heartbeat, that are not in the presence of danger at all, but something else entirely. In these cases, our bodies can misinterpret these physiological signals as being indicators of danger or a "true threat." For example, people may experience learned anxiety due to previous associations between elevated heart rate and panic attacks and may misinterpret bodily sensations as signs of imminent death or loss of control. In this way, one may start to fear these physiological responses, which is what we call "fear of fear" (Craske & Barlow, 2007). "Fear of fear" maintains or perpetuates panic attacks and panic symptoms, which becomes a vicious cycle. In other words, you experience an increased heart rate, which you interpret as negative, which makes you feel anxious, which further makes your heart rate increase and it often spirals from there. These associations may almost happen automatically, even without conscious thought, but this is what is likely going on behind the scenes.
Anxiety attacks symptoms and heart attack symptoms can seem similar because their signs and symptoms can be similar. But most medical professionals can quickly tell the difference as heart attacks have distinct symptoms that aren’t anxiety-like. If you are unsure of which is an anxiety attack symptom and which is a heart attack symptom, seek immediate medical advice. If the doctor diagnoses your symptoms as anxiety attack symptoms, you can feel confident the doctor’s diagnosis is correct. Therefore, there is no need to worry about a heart attack.
Dialectical Behavior Therapy (DBT) is form of Cognitive therapy that emphasizes individual psychotherapy as well as group skills training to help people learns new skills and strategies—including mindfulness and distress tolerance– to manage their anxiety and panic. According to the American Psychological Association therapists who practicing DBT aim to strike a balance between validation and change by clearly communicating acceptance of who the client is and the challenges the client faces, while at the same time helping the client to learn new skills to improve emotion regulation, interpersonal communication skills and how to participate in life and cope with problems without defaulting to impulsive behavior.
Panic attacks may also be caused by substances. Discontinuation or marked reduction in the dose of a substance such as a drug (drug withdrawal), for example an antidepressant (antidepressant discontinuation syndrome), can cause a panic attack. According to the Harvard Mental Health Letter, "the most commonly reported side effects of smoking marijuana are anxiety and panic attacks. Studies report that about 20% to 30% of recreational users experience such problems after smoking marijuana."
The causes of anxiety attacks are not well understood. Some traumatic life events can set off anxiety attacks if the person is prone to depression or anxiety disorders. Also, medical conditions and some medications may trigger anxiety attacks. Many believe anxiety attacks run in families with a genetic predisposition. In other words, if your mom and her sister had anxiety attacks, it’s likely you will, too.
Many factors are linked to the development of panic attacks and panic disorder. In terms of personality, those who are more prone to anxiety, and more likely to believe that anxiety is harmful, are more likely to experience panic attacks. Stressors and interpersonal issues, such as a death in the family or adverse life events, tend to be seen in the months preceding a panic attack.
Selective mutism: A somewhat rare disorder associated with anxiety is selective mutism. Selective mutism occurs when people fail to speak in specific social situations despite having normal language skills. Selective mutism usually occurs before the age of 5 and is often associated with extreme shyness, fear of social embarrassment, compulsive traits, withdrawal, clinging behavior, and temper tantrums. People diagnosed with selective mutism are often also diagnosed with other anxiety disorders.
