Social and environmental stressors
Symptoms of anxiety
- Repression. The person pushes anxious thoughts or ideas out of conscious awareness.
- Displacement. Anxiety from one source is attached to a different object or event. Phobias are an example of the mechanism of displacement in psychoanalytic theory.
- Rationalization. The person justifies the anxious feelings by saying that any normal person would feel anxious in their situation.
- Somatization. The anxiety emerges in the form of physical complaints and illnesses, such as recurrent headaches, stomach upsets, or muscle and joint pain.
- Delusion formation. The person converts anxious feelings into conspiracy theories or similar ideas without reality testing. Delusion formation can involve groups as well as individuals.
Anxiety may be rational, such as the anxiety about doing well in a new job, about one's own or someone else's illness, about passing an examination, or about moving to a new community. People also feel realistic anxiety about world dangers, such as the possibility of war, and about social and economic changes that may affect their livelihood or way of living. Most persons find healthy ways to deal with their normal quota of anxiety.
Factors that can precipitate an attack of anxiety include any pathophysiological event that interferes with satisfaction of the basic human physiological needs. Situational factors include actual or perceived threat to self-concept, loss of significant others, threat to biological integrity, change in environment, change in socioeconomic status, and transmission of another person's anxiety to the individual. Other etiologic factors are associated with a threat to completion of developmental tasks at various life stages, for example, a threat to an adolescent in the completion of developmental tasks associated with sexual development, peer relationships, and independence.
Interventions. Measures to assist the individuals suffering from anxiety are aimed at helping them recognize their anxiety and their usual means of coping with it, and providing alternate, more healthful coping mechanisms that give a sense of physiological and psychological comfort.
People with anxiety disorders experience both the subjective emotion and various physical manifestations resulting from muscular tension and autonomic nervous system activity. This can produce a variety of symptoms, including sweating, dizziness, shortness of breath, insomnia, loss of appetite, and palpitations. The source of the anxiety lies in unconscious fears, unresolved conflicts, forbidden impulses, or threatening memories. Symptoms are often triggered by an apparently harmless stimulus that the patient unconsciously links with a deeply buried, anxiety-producing experience. Chronic anxiety can lead to various somatic alterations. The onset of anxiety may be gradual or sudden. Some persons experience incapacitating acute anxiety (as in panic disorder) while others manifest their anxiety through avoidant behavior patterns (phobias, obsessive-compulsive disorder). Anxiety disorders include: panic disorder, agoraphobia, social phobia, specific phobia, obsessive-compulsive disorder, posttraumatic stress disorder, acute stress disorder, generalized anxiety disorder, and substance-induced anxiety disorder.
cyclosporine ophthalmic emulsion
Restasis, Sandimmun (UK)CNS: tremor, headache, confusion, paresthesia, insomnia, anxiety, depression, lethargy, weakness

FDA Box Warning
• Drug should be prescribed only by physicians experienced in managing systemic immunosuppressive therapy for indicated disease. At doses used for solid-organ transplantation, it should be prescribed only by physicians experienced in immunosuppressive therapy and management of organ transplant recipients. Patient should be managed in facility with adequate laboratory and medical resources. Physician responsible for maintenance therapy should have complete information needed for patient follow-up.
• Neoral may increase susceptibility to infection and neoplasia. In kidney, liver, and heart transplant patients, drug may be given with other immunosuppressants.
• Sandimmune should be given with adrenal corticosteroids but not other immunosuppressants. In transplant patients, increased susceptibility to infection and development of lymphoma and other neoplasms may result from increased immunosuppression.
• Sandimmune and Neoral aren't bioequivalent. Don't use interchangeably without physician supervision.
• In patients receiving Sandimmune soft-gelatin capsules and oral solution, monitor at repeated intervals (due to erratic absorption).

Patient discussion about anxiety
Q. Social Anxiety I have found myself wondering more and more about social anxiety. My partner seemed to develop social anxiety around the same time she was diagnosed bipolar. i am wondering how many of you also suffer from soical anxiety and if you feel it is a result of bipolar disorder (perhaps personal knowledge of the possible behaviours associated with the illness) or if it is a seperate and unrelated symptom?
social anxiety disorder is best defeated by groups like
the Toastmasters International or the dale carnegie course.
