People with panic disorder have sudden and repeated attacks of fear that last for several minutes or longer. These are called panic attacks. Panic attacks are characterized by a fear of disaster or of losing control even when there is no real danger. A person may also have a strong physical reaction during a panic attack. It may feel like having a heart attack. Panic attacks can occur at any time, and many people with panic disorder worry about and dread the possibility of having another attack.
Generalized Anxiety Disorder is different than having a phobia about something. People with phobias are fearful of something in particular – for example, spiders, heights, or speaking in public. If you have Generalized Anxiety Disorder, you have an uneasy feeling about life in general. Often associated with feelings of dread or unease, you are in a state of constant worry over everything. If a friend doesn’t call you back within an hour, you may start to worry you did something wrong and the friend is upset with you. If you are waiting for someone to pick you up and he is a few minutes late – you may start to fear the worst – that he was in an accident, instead of thinking something more minor, like he got stuck in traffic. The feelings are not as intense as those that occur during a panic attack episode; however, the feelings are long-lasting. This results in having anxiety toward your life in general and the inability to relax – what some may consider far more debilitating than a specific phobia to a certain thing or situation, which you could possible avoid. There is no “off” switch. If you are suffering from Generalized Anxiety Disorder, you are experiencing a constant state of worry – and you cannot avoid it, because life, in general, is causing you anxiety.
As is true for other mood and anxiety disorders, the use of Selective Serotonin Reuptake Inhibitors (SSRI's; e.g.., Paxil, Prozac, Zoloft), Benzodiazepines (e.g., Xanax, Lorazepam), and Selective Norepinephrine Reuptake Inhibitors (SNRI's; e.g., Cymbalta, Effexor, Pristiq) are common medical treatments for panic disorder. Additionally, D-cycloserine is a medication that is now being explored as a way to enhance effects of CBT (e.g., Hofmann et al., 2013). These medications may have side effects and taking them can lead to tolerance, withdrawal symptoms, and dependence, so it is important that you consult with a physician before starting or stopping these medications. There is evidence that taking one of these medications in addition to receiving behavioral therapy (e.g., CBT) can significantly benefit patients with panic disorder, although seeking psychotherapy in itself is largely effective (Arch et al., 2017).
In people with anxiety disorders, the brain circuitry that controls the threat response goes awry. At the heart of the circuit is the amygdala, a structure that flags incoming signals as worrisome and communicates with other parts of the brain to put the body on alert for danger. Early life events, especially traumatic ones, can program the circuitry so that it is oversensitive and sends out alarms too frequently and with only minor provocations. Survival mandates a system for perceiving threats and taking quick, automatic action, but those with anxiety see threats where there are none, perhaps because emotional memories color their perceptions.
Social anxiety disorder (previously called social phobia): People with social anxiety disorder have a general intense fear of, or anxiety toward, social or performance situations. They worry that actions or behaviors associated with their anxiety will be negatively evaluated by others, leading them to feel embarrassed. This worry often causes people with social anxiety to avoid social situations. Social anxiety disorder can manifest in a range of situations, such as within the workplace or the school environment.
