Anxiety Disorders

A combination of cognitive-behavioral therapy (CBT) and antidepressants to treat anxiety disorders in youngsters has yielded positive results in a government-funded study that was published online by the New England Journal of Medicine.1

One minute she's breathing room air and the next you're barking orders at a team wheeling in a crash cart. You review signs and symptoms you missed, the rough rhythm of her heart before she coded. You want to believe your reasoning was as elegant as a glass filled with cabernet, and you want to forget the bottle you imagine resting on a tray table at forty thousand feet, ready to tumble when the captain announces the plane is diving for an unscheduled stop. But I don't need images of air disasters to convince you doctors live somewhere between reason and panic: just flip open your laryngoscope, visualize the vocal chords, and forget you have fifteen seconds to thread the tube before the breathless body on the bed turns blue.

Older adults can present with anxiety or worries about physical health (illness, changes in vision or hearing), cognitive difficulties, finances, and changes in life status (widowhood, care-giving responsibilities, retirement). Clinicians need to be aware that older adults may deny psychological symptoms of anxiety (fear, worry) but endorse similar emotions with different words (worries, concerns).

Traumatic brain injury (TBI) is the major cause of death and disability among young adults. In spite of preventive measures, the incidence of a TBI associated with motor vehicle accidents, falls, assault, and high-contact sports continues to be alarmingly high and constitutes a major public health concern. In addition, the recent military operations in Iraq and Afghanistan have resulted in a large number of persons with blast injuries and brain trauma. Taking into account that cognitive and behavioral changes have a decisive influence in the recovery and community reintegration of patients with a TBI, there is a renewed interest in developing systematic studies of the frequency, mechanism, and treatment of the psychopathological alterations observed among these patients.

In this overview of pica, we review its causes and prevalence. In addition, we discuss some of the associated complications as well as current treatment strategies.

The ocurrence and severity of anxiety disorders have been correlated with fluctuations in female sex steroid levels in both epidemiological and experimental studies.1-5 Female reproductive hormones play a role not only in the development and course of anxiety disorders but also in treatment response.

Anxiety disorders are the most prevalent disorders among children and adolescents in both community and clinical settings. The high prevalence of anxiety disorders in children and adolescents leads to increased interest in the development and implementation of effective treatments.

Panic disorder with or without agoraphobia is a chronic, debilitating psychiatric illness that affects about 4.7% of the general US population.

Both cognitive-behavioral and pharmacological treatments for panic disorder have been found to be effective over the short term. Not all patients, however, can tolerate or fully respond to these approaches, and the effectiveness of these interventions over the long term remains unclear.

Anxiety disorders are some of the most common mental health problems that confront clinicians, either as a primary diagnosis or as comorbid conditions.

In part 1 of this column, I reviewed research findings of the most substantiated nonpharmacological and integrative treatments for anxiety, such as kava-kava, L-theanine, applied relaxation, yoga, meditation and mindfulness training, virtual reality graded exposure therapy, and biofeedback training.

A recent longitudinal study examined the potential relationship between social anxiety disorder during adolescence and young adulthood and the subsequent development of depression.1

Patients with chronic pain and head injury frequently have comorbid anxiety and depressive disorders, with depressive disorders appearing to be more predominant. A number of studies show that depressive spectrum illness develops in 40% to 80% of patients with chronic pain; in a majority of these cases, the mood disorder is caused by chronic pain.

Comorbidity of psychiatric syndromes is quite common-in a 12-month period, almost 50% of adults in the United States with any psychiatric disorder had 2 or more disorders.

Almost one third of US mental health care costs (approximately $50 billion) go toward the treatment of anxiety disorders. Conventional pharmacological treatments for anxiety are often beneficial but have limited efficacy.

Department of Defense (DOD) medical centers, community hospitals, and clinics throughout the United States were tasked with hiring 44 "contract" psychiatrists over the summer as a response to growing concerns about inadequate mental health care for soldiers in Iraq and Afghanistan and those returning home.

The comorbidity of anxiety disorders with bipolar disorder is a rule, not an exception, with a negative impact on both course and treatment outcome. So far, there are no guidelines or consensus for the treatment of this comorbidity.

A new set of guidelines confirms the value of psychotherapy, medications-including SSRIs-and combinations of therapy in managing anxiety disorders in children.

In this article, we examine the relationship between anxiety disorders and SDs, using DSM-IV-TR categories, although we are conscious of the limits of this approach. In doing so, we will consider not only the dichotomy between normal and pathological functioning but also the issue of sexual satisfaction as part of wellness.

Up Against the Wall

It is not uncommon for combat veterans to exhibit a wide range of psychological conditions, from schizophrenia to depression to posttraumatic stress disorder (PTSD), but how do these disorders affect domestic partners, who often serve as veterans' caregivers?

Worsening anxiety is a common symptom that may result in psychiatric consultation or evaluation in an emergency setting. Aneurysms are rarely considered in the medical differential for anxiety disorders, and the available literature and research regarding this possible connection are very limited. Overlooking this diagnosis, however, can have disastrous consequences. Here we present 2 case reports as well as a review of the literature regarding a possible relationship between aortic and thoracic aneurysms and psychiatric symptoms.

Chronic primary daily headache may not be a singular disorder but rather one with various subtypes. Chronic migraine (also referred to as evolved migraine or transformed migraine), chronic tension-type headache, newly defined daily persistent headache, hemicrania continua, and post-traumatic headache are now recognized as subcategories of chronic daily headache

Treatment interventions via telephone, Internet, and through other telemedical services are gaining popularity, especially in rural areas where licensed clinicians might not be available. Dr Per Carlbring and colleagues recently evaluated a 10-week, Internet-based, self-help program with weekly telephone calls for patients who had panic disorder with or without agoraphobia. The results were published in the December 2006 issue of the American Journal of Psychiatry.

Panic disorder occurs in about 1 in 5 individuals who have bipolar disorder. Anxiety amplifies the distress caused by depression and mania, but pharmacological approaches are tricky and under-studied. Frequent comorbidity and evidence of a possible genetic relationship of bipolar and panic disorders are suggestive of a causal relationship between the 2. Thus, it may be fruitful to look more closely at evidence for common biological abnormalities in both disorders to find a pathophysiological mechanism that links mania, depression, and panic attacks. Mood episodes and panic attacks can both be modeled as the result of deficits in amygdala-mediated emotional conditioning. From this model, some insight may be gained for potentially helpful treatment strategies for the 2 disorders when they occur together.
