A helpful approach to distinguishing normal anxiety from an anxiety disorder is to identify the cause of the anxiety, and then assess whether the anxiety symptoms are a proportional response to it. Worries, fears, and intrusive thoughts that are extreme, unrealistic, or exaggerated and interfere with normal life and functioning could constitute an anxiety disorder. For instance, being concerned about getting sick and taking steps to avoid germs, like using hand sanitizer and avoiding touching door handles, does not necessarily constitute an anxiety disorder; however, if the concern about sickness makes it difficult to leave the house, then it is possible that the person suffers from an anxiety or anxiety-related disorder.
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:
Research is inconsistent as to whether nutritional deficiencies (for example, zinc or magnesium deficiency) may be risk factors for panic disorder. While food additives like aspartame, alone or in combination with food dyes, are suspected to play a role in the development of panic attacks in some people, it has not been confirmed by research so far.
Without treatment, panic attacks tend to occur repeatedly for months or years. While they typically begin in young adulthood, the symptoms may arise earlier or later in life in some people. Complications, which are symptoms that can develop as a result of continued panic attacks and develop into other mental illnesses, may include specific irrational fears (phobias), especially of leaving home (agoraphobia) and avoidance of social situations. Other possible complications can include depression, work or school problems, suicidal thoughts or actions, financial problems, and alcohol or other substance abuse. For children and adolescents, panic disorder can even interfere with normal development. Panic disorder and other anxiety disorders also predispose sufferers to developing heart or gastrointestinal diseases, high blood pressure or diabetes, having more severe symptoms if they have a respiratory disease, and of dying prematurely.
Some benefits of benzodiazepines are that they are effective in relieving anxiety and take effect more quickly than antidepressant medications often prescribed for anxiety. Some drawbacks of benzodiazepines are that people can build up a tolerance to them if they are taken over a long period of time and they may need higher and higher doses to get the same effect. Some people may even become dependent on them.
While the term "test anxiety" refers specifically to students, many workers share the same experience with regard to their career or profession. The fear of failing at a task and being negatively evaluated for failure can have a similarly negative effect on the adult. Management of test anxiety focuses on achieving relaxation and developing mechanisms to manage anxiety.
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).
