Anxiety disorders depression with, treatment

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 Only one subject was known to have withdrawn secondary to severe side effects.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... 

As might be suggested by the treatment outcome studies referred to above, anxiety disorders such as panic disorder have a chronic clinical course. A retrospective survey that reviewed literature on the course of depression and anxiety disorder before effective treatment became available [Keller and Baker 1992] showed that a high proportion of patients had little or no improvement in their condition over a number of years. Roughly half of 300 patients with panic disorder who received no active treatments showed no improvement over a 20-year period, for example. Like depression, panic dis-...

Antidepressant drugs are used to manage depressive episodes such as major depression or depression accompanied by anxiety. These drugs may be used in conjunction with psychotherapy in severe depression. The SSRIs also are used to treat obsessive-compulsive disorders. The uses of individual antidepressants are given in the Summary Drug Table Antidepressants. Treatment is usually continued for 9 months after recovery from the first major depressive episode. If the patient, at a later date, experiences another major depressive episode, treatment is continued for 5 years, and with a third episode, treatment is continued indefinitely. 

Medications that have been used as treatment for anxiety and depression in the postwithdrawal state include antidepressants, benzodia2epines and other anxiolytics, antipsychotics, and lithium. In general, the indications for use of these medications in alcoholic patients are similar to those for use in nonalcoholic patients with psychiatric illness. However, following careful differential diagnosis, the choice of medications should take into account the increased potential for adverse effects when the medications are prescribed to alcoholic patients. For example, adverse effects can result from pharmacodynamic interactions with medical disorders commonly present in alcoholic patients, as well as from pharmacokinetic interactions with medications prescribed to treat these disorders (Sullivan and O Connor 2004). 

Out-patient treatment is substantially cheaper than in-patient management and is generally as effective (Lowman, 1991). A French study on patients with generalized anxiety disorder estimated costs per patient over 3 months to he US 423 for hospitalization, 335 for out-patient services and 43 for medications (Souetre et al, 1994). Comorbid conditions (mostly alcoholism and depression) doubled these direct health-care costs. Over three-quarters of all patients were taking anxiolytic medication. 

Evaluation of the economics of mental illness in primary care is an ongoing initiative of the UK Department of Health (Lloyd and Jenkins, 1995). A similar American study in Washington State included sub-threshold anxiety or depression, but these imposed relatively little economic load compared with disorder-level anxiety or depression (Simon et al, 1995). Mental health treatment accounted for only a small part of overall utilization, approximately 5%. Nevertheless, most patients with anxiety or depressive disorders showed considerable improvement. This was accompanied by only modest reductions in cost. 

Evaluate the clinical outcomes of treatment by using the UPDRS. In addition, periodically ask patients to record the amount of on and off time they have with and without dyskinesias in a diary. There are a variety of scales that can be used to assess QOL, depression, anxiety, and sleep disorders. Patients with PD cannot be cured but treatment can delay the progression of symptoms and improve QOL. Delaying the patient s admission into a nursing home is a good outcome. 

ADHD is rarely encountered without comorbid conditions and often is underdiagnosed. Between 40% and 75% of patients with ADHD will have one or more comorbidities (e.g., learning disabilities, oppositional defiant conduct, anxiety, or depressive disorders).10 It is important to identify other coexisting conditions in patients with ADHD to assist in initial and ongoing selection of treatment.

How might drugs with CNS depressant properties aid in the treatment of anxiety disorders ... 

As the first SNRI drug approved, venlafaxine has become one of the first-line choices for depression and anxiety disorder [45,46]. An active metabolite, desvenlafaxine (19), is also under clinical development for the treatment of major depressive disorders [47], Preclinical studies also indicate that 19 may be effective in relieving vasomotor symptoms associated with menopause (e.g., hot flushes and night sweats) [47,48]. Desvenlafaxine is reported to be in clinical development for the treatment of fibromyalgia and neuropathic pain, as well as vasomotor symptoms associated with menopause [68]. 

When is medication indicated in the treatment of psychiatric illness There is no short answer to this question. At one end of the continuum, patients with schizophrenia and other psychotic disorders, bipolar disorder, and severe major depressive disorder should always be considered candidates for pharmacotherapy, and neglecting to use medication, or at least discuss the use of medication with these patients, fails to adhere to the current standard of mental health care. Less severe depressive disorders, many anxiety disorders, and binge eating disorders can respond to psychotherapy and/or pharmacotherapy, and different therapies can target distinct symptom complexes in these situations. Finally, at the opposite end of the spectrum, adjustment disorders, specific phobias, or grief reactions should generally be treated with psychotherapy alone. 

Nefazodone is approved for treatment of major depression and appears particularly effective iu treatiug depressed patieuts with agitation or anxiety. Its role in treating anxiety disorders is being studied. 

Substance-Induced Anxiety Disorder. Numerous medicines and drugs of abuse can produce panic attacks. Panic attacks can be triggered by central nervous system stimulants such as cocaine, methamphetamine, caffeine, over-the-counter herbal stimulants such as ephedra, or any of the medications commonly used to treat narcolepsy and ADHD, including psychostimulants and modafinil. Thyroid supplementation with thyroxine (Synthroid) or triiodothyronine (Cytomel) can rarely produce panic attacks. Abrupt withdrawal from central nervous system depressants such as alcohol, barbiturates, and benzodiazepines can cause panic attacks as well. This can be especially problematic with short-acting benzodiazepines such as alprazolam (Xanax), which is an effective treatment for panic disorder but which has been associated with between dose withdrawal symptoms. 

Generalized Sociai Anxiety Disorder, Treatment Resistance. A significant minority of patients will not experience a satisfactory treatment response to antidepressant therapy, even after a trial of adequate duration at full strength doses. For those with comorbid depression who are experiencing no benefit from SSRI treatment for either the anxiety or depression, then switching treatment is advisable. The options include switching to another SSRI, a SNRI (venlafaxine or perhaps dulox-etine), or, when other alternatives fail, phenelzine. 

Tricyclic Antidepressants (TCAs). Because of their effectiveness not only for depression but for anxiety disorders such as panic disorder as well, TCAs were the first medications formally tested in the treatment of PTSD. Three TCAs, amitriptyline, imipramine, and desipramine, have been studied in small trials, producing modest benefit for reexperiencing and hyperarousal symptoms, without any relief of avoidance/numbing symptoms. Given this limited benefit in conjunction with the side effect burden and potential for toxicity in a suicide prone population, TCAs are infrequently used in the treatment of PTSD. Please refer to Chapter 3 for more information regarding TCAs. 

Psychiatric medications do not currently play a prominent role in the treatment of cocaine-dependent patients (see Table 6.4). Although researchers have labored to find medications to treat cocaine addiction, there have not been any notable breakthroughs. As with other substance use disorders, the presence of a psychiatric disorder for which medication is indicated (i.e., depression, anxiety disorders, bipolar affective disorder, or schizophrenia) should prompt appropriate treatment. Similar to the presence of alcohol intoxication, deferring a diagnosis for a day or two in a new patient with no past history is often the more prudent course. 

Once chronic insomnia has developed, it hardly ever spontaneously resolves without treatment or intervention. The toll of chronic insomnia can be very high and the frustration it produces may precipitate a clinical depression or an anxiety disorder. Insomnia is also associated with decreased productivity in the workplace and more frequent use of medical services. Einally, substance abuse problems may result from the inappropriate use of alcohol or sedatives to induce sleep or caffeine and other stimulants to maintain alertness during the day.
