Experiencing a chronic medical condition or severe or frequent illness can also increase risk for anxiety disorders, as well as dealing with significant illness of a family member or loved one. Given that several medical conditions have been linked to significant anxiety, in some cases a physician may perform medical tests to rule out an underlying medical condition. For instance, thyroid disease is often characterized by experiencing significant symptoms of anxiety. Menopause, heart disease, and diabetes have also been linked to anxiety symptoms. Additionally, drug abuse or withdrawal for many substances is characterized by acute anxiety, and chronic substance abuse can increase risk for developing an anxiety disorder. Anxiety can also be a side effect of certain medications. Experiencing significant sleep disturbances, such as difficulty falling asleep or staying asleep, may also be a risk factor for developing an anxiety disorder.
In the central nervous system (CNS), the major mediators of the symptoms of anxiety disorders appear to be norepinephrine, serotonin, dopamine, and gamma-aminobutyric acid (GABA). Other neurotransmitters and peptides, such as corticotropin-releasing factor, may be involved. Peripherally, the autonomic nervous system, especially the sympathetic nervous system, mediates many of the symptoms. Increased flow in the right parahippocampal region and reduced serotonin type 1A receptor binding in the anterior and posterior cingulate and raphe of patients are the diagnostic factors for prevalence of anxiety disorder.
A person with separation anxiety disorder is excessively fearful or anxious about separation from those with whom he or she is attached. The feeling is beyond what is appropriate for the person’s age, persists (at least four weeks in children and six months in adults) and causes problems functioning. A person with separation anxiety disorder may be persistently worried about losing the person closest to him or her, may be reluctant or refuse to go out or sleep away from home or without that person, or may experience nightmares about separation. Physical symptoms of distress often develop in childhood, but symptoms can carry though adulthood.
More medications are available than ever before to effectively treat anxiety disorders. These include antidepressants (SSRIs, SNRIs, Tricyclic Antidepressants, MAOIs), tranquilizers (benzodiazepines, etc.) and in some cases, anticonvulsants. A person may have to try more than one medication before finding a drug or combination of drugs that works for them. Learn more about medications.
Buspirone is a drug indicated for the treatment of anxiety. This drug has high efficacy for Generalized Anxiety Disorder and is particularly effective at reducing the cognitive and interpersonal problems associated with anxiety. Unlike benzodiazepines, buspirone does not have a sedative effect or interact with alcohol. Most importantly there is a very low risk of developing a dependence on buspirone. Its side effects are minimal but can include dizziness, nervousness, and headaches. BuSpar and Vanspar are brand names associated with buspirone.
There are things that people with panic disorder can do to assist with their own recovery. Since substances like caffeine, alcohol, and illicit drugs can worsen panic attacks, those things should be avoided. Other tips for managing panic attacks include engaging in aerobic exercise and stress-management techniques like deep breathing and yoga on a regular basis, since these activities have also been found to help decrease panic attacks.
Anxiety can be either a short-term "state" or a long-term "trait". Whereas trait anxiety represents worrying about future events, anxiety disorders are a group of mental disorders characterized by feelings of anxiety and fear. Anxiety disorders are partly genetic but may also be due to drug use, including alcohol, caffeine, and benzodiazepines (which are often prescribed to treat anxiety), as well as withdrawal from drugs of abuse. They often occur with other mental disorders, particularly bipolar disorder, eating disorders, major depressive disorder, or certain personality disorders. Common treatment options include lifestyle changes, medication, and therapy. Metacognitive therapy seeks to diminish anxiety through reducing worry, which is seen[by whom?] as a consequence of metacognitive beliefs.
