Anxiety disorders symptoms

Of the SSRIs, fluoxetine has been studied most extensively. Birmaher et al. (1994) and Fairbanks et al. (1997) both found significant improvement in various anxiety disorder symptoms in typically developing children. Fluoxetine was also found to be effective in the treatment of selective mutism (Black and Udhe, 1994 Dummit et ah, 1996). Fluoxetine has also been studied in individuals with MR and autistic disorder. In an open trial. Cook et al (1992) found that fluoxetine was associated with significant improvement in the Clinical Global Impression (CGI) severity ratings in 15 of 23 individuals (65%) with autistic disorder and in 10 of 16 individuals (62%) with MR. All of the SSRIs appear to have similar properties and have been approved for panic disorder, phobias, OCD, and anxiety disorder. Sertraline has been approved for treatment of PTSD, and paroxetine, for social phobia. 

Although alprazolam is effective in the treatment of panic disorder, research has shown mixed results as to whether this drug can be effective in the treatment of social anxiety disorder. Although some studies have shown that alprazolam is not any better than the placebo, some have also shown that alprazolam can reduce some of social anxiety disorder symptoms. 

OCD on its own often starts in late adolescence and has a chronic and pervasive course unless treated. OCD starting later on in life is often associated with affective or anxiety disorders. Symptoms often abate briefly if the individual is taken to a new environment. 

Anxiety symptoms are an inherent part of the initial clinical presentation of several diseases, thus complicating the distinction between anxiety disorders and medical disorders. If the anxiety symptoms are secondary to a medical illness, they usually will subside as the medical situation stabilizes. However, the knowledge that one has a physical illness (e.g., cancer and diabetes) can trigger anxious feelings and further complicate therapy. Persistent anxiety subsequent to a physical illness requires further assessment for an anxiety disorder. Symptoms of anxiety frequently present in medical disorders include palpitations, tachycardia, chest pain or tightness, shortness of breath, and hyperventilation. Medical disorders most closely associated with anxiety are listed in Table 69-1. " About 50% of patients with GAD have irritable bowel syndrome. ... 

Antianxiety drugp are used in the management of anxiety disorders and short-term treatment of the symptoms of anxiety. Long-term use of these dru is usually not recommended because prolonged therapy can result in drug dependence and serious withdrawal symptoms. 

To reach agreed criteria, anxiety disorders must cause significant distress or interference with the patient s life, leading to significant personal costs. Symptoms alone are... 

Unlike most anxiety disorders, panic disorder leads to a high utilization of general medical services, reflecting the frequency, severity and alarming nature of physical symptoms such as palpitations, gastrointestinal distress, respiratory problems and headaches (Zaubler and Katon, 1998). This can result in extensive investigations and sometimes inappropriate but expensive medications. 

The mean age of onset of bipolar disorder is 20, although onset may occur in early childhood to the mid-40s.1 If the onset of symptoms occurs after 60 years of age, the condition is probably secondary to medical causes. Early onset of bipolar disorder is associated with greater comorbidities, more mood episodes, a greater proportion of days depressed, and greater lifetime risk of suicide attempts, compared to bipolar disorder with a later onset. Substance abuse and anxiety disorders are more common in patients with an early onset. Patients with bipolar disorder also have higher rates of suicidal thinking, suicidal attempts, and completed suicides. 

List common presenting symptoms of generalized anxiety, panic, and social anxiety disorders. 

O The goals of therapy for generalized anxiety disorder are to acutely reduce the severity and duration of anxiety symptoms and restore overall functioning. The long-term goal in generalized anxiety disorder is to achieve and maintain remission. 

Pharmacotherapy of social anxiety disorder should lead to improvement in physiologic symptoms of anxiety and fear, functionality, and overall well-being. 

Anxiety disorders represent a diverse class of illnesses, with varied ages of onset. For example, according to the NCS-R epidemiologic study,3 PD and GAD had a median age of onset of 24 and 31 years, respectively, whereas specific phobia and social anxiety disorder (SAD) tend to develop much earlier (median age of onset 7 and 13 years, respectively). Although GAD and PD may not manifest fully until adulthood, as many as half of adult anxiety patients report subthreshold symptoms during childhood.6... 

Anxiety disorders are characterized as chronic in nature with low rates of spontaneous symptom remission and high rates of relapse. Research illustrates that symptoms of anxiety disorders tend to wax and wane, with less than a third of patients remitting spontaneously.7 In a 12-year follow-up study of anxiety disorder patients, recurrence rates were similar between PD with and without agoraphobia (56% and 58%, respectively) despite great differences seen in reported rates of remission (48% and 82% with treatment, respectively).8 Fifty-eight percent of treated GAD patients experienced symptom remission, with 55% experiencing recurrence during the follow-up period. While individuals with SAD had the lowest remission rate with treatment (37%), those who did respond had the lowest rate of recurrence (39%) compared with patients with other anxiety disorders. 

Assess the patient s symptoms and level of functional impairment to determine if pharmacotherapy is appropriate for the anxiety disorder. 

Although ADHD generally is considered a childhood disorder, symptoms can persist into adolescence and adulthood. The prevalence of adulthood ADHD is estimated to be 4%, with 60% of adults having manifested symptoms of ADHD from childhood.8,9 Further, problems associated with ADHD (e.g., social, marital, academic, career, anxiety, depression, smoking, and substance-abuse problems) increase with the transition of patients into adulthood. 

Another study with citalopram evaluated its efficacy in the treatment of social anxiety disorder along with co-morbid major depression (Schneier etal., 2003). The outpatients (n= 21) were predominantly Hispanic (76%) and from New York. Response rates for the intent-to-treat sample were 66.7% for social anxiety disorder and 76.2% for major depression. Only one subject was known to have withdrawn secondary to severe side effects. The mean dose of the medication was 37.6 mg/day and there was no placebo control. The depressive symptoms tended to improve... 

Patients with anxiety and depression often have bowel symptoms. Gorad et al. compared 21 psychiatric outpatients with generalized anxiety disorders and depression with an equal number of healthy controls. Whole-gut transit time (WGTT) was measured using abdominal radiography after ingestion of radioopaque markers, and found to be shorter in patients with anxiety (mean 14 h ... 

Anxiety disorders include a constellation of disorders in which anxiety and associated symptoms are irrational or experienced at a level of severity that impairs functioning. The characteristic features are anxiety and avoidance.
