Almost everyone has something they fear – maybe it's spiders, enclosed spaces, or heights. When we encounter these "threats," our hearts might begin to race, or our hands may become sweaty. Many fear-related disorders are treated using exposure therapy. This helps people "unlearn" a threat fear response by breaking the association between the "trigger." Imagination allows patients to immerse themselves with a triggering stimulus in a controlled way, at their own pace, which is why it could be a promising new form of treatment.
The Diagnostic and Statistical Manual of Mental Disorders (DSM) is the handbook used for diagnosis of mental health disorders, and is widely used by health care professionals around the world. For each disorder, the DSM has a description of symptoms and other criteria to diagnose the disorder. The DSM is important, because it allows different clinicians and/or researchers to use the same language when discussing mental health disorders. The first DSM was published in 1952 and has been updated several times after new research and knowledge became available. In 2013, the most recent version of the DSM, the DSM-5, was released. There are a few important differences with its predecessor DSM-IV regarding anxiety disorders. First, Obsessive Compulsive Disorder (OCD) is not part of the anxiety disorders any more, but now has its own category: Obsessive-Compulsive, Stereotypic and related disorders. Second, Post-Traumatic Stress Disorder (PTSD) now also has its own category: Trauma and Stressor-related Disorders.
Social anxiety varies in degree and severity. For some people, it is characterized by experiencing discomfort or awkwardness during physical social contact (e.g. embracing, shaking hands, etc.), while in other cases it can lead to a fear of interacting with unfamiliar people altogether. Those suffering from this condition may restrict their lifestyles to accommodate the anxiety, minimizing social interaction whenever possible. Social anxiety also forms a core aspect of certain personality disorders, including avoidant personality disorder.
If you’ve ever had a panic attack, you’ll know it can be both a terrifying experience and exhausting experience. Panic disorder is a diagnosis given to people who experience recurrent unexpected panic attacks—that is, the attack appears to occur from out of the blue. Panic attack symptoms include sweating, shaking, shortness of breath, feelings of choking, chest pain, and a fear of dying.
Anxiety is associated with abnormal patterns of activity in the brain. One way to treat anxiety is to directly target abnormal nerve cell activity. Neuromodulation or brain stimulation therapy is a non-invasive and painless therapy that stimulates the human brain. In some recent clinical trials, patients that did not respond to more traditional forms of treatment (i.e. medication) showed a reduction in symptoms of depression and anxiety. There are two main types of neuromodulation:
People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
