Anxiety Treatment in Seattle

Evidenced-based Treatment for Anxiety Disorders

Anxiety disorders affect many people, causing them to be filled with fearfulness and uncertainty. Unlike the relatively mild, brief anxiety caused by a stressful event, such as speaking in public or a first date, anxiety disorders last at least 6 months and can get worse if they are not treated.

Anxiety disorders commonly occur along with other mental or physical illnesses, including alcohol or substance abuse, which may mask anxiety symptoms or make them worse. In some cases, these other illnesses need to be treated before a person will respond to treatment for the anxiety disorder.

This is not a complete list of the different anxiety disorders out there by any means, nor is it completely comprehensive in each description. There are many kinds of anxiety. These just happen to the most talked about and diagnosed at this particular moment. Regardless of which anxiety disorder the diagnosis is for, it is important to remember that the sufferer is in need of help and acceptance.

You don’t have to understand anxiety to be able to offer an ear to talk to or some words to keep them grounded in the moment. Remind the sufferer that they are alright, that what they are feeling are just symptoms of their anxiety and that it will pass is given the time. Aside from that, just make sure that they know you are there with them and wait it out.

Social Anxiety

Social Anxiety Disorder is characterized by marked, persistent, and unreasonable fear of being observed or evaluated negatively by others in social performance or interaction situations and is associated with somatic and cognitive symptoms. The feared situations are avoided or else are endured with intense anxiety or distress. These situations include fear of speaking in public, speaking to unfamiliar people or being exposed to possible scrutiny by others.

Those with Social Anxiety Disorder experience panic attacks related to social situations. this can manifest in a fear of public speaking or stage fright and can be so severe that they avoid going into public altogether.

Social anxiety can also have symptoms of severe self-consciousness and a general fear of being around others. Someone with social anxiety might find it hard to speak when other people are present even if they aren’t addressing the crowd as a whole.

Social anxiety is mainly treated with SSRIs and therapy. As we stated before, just because a treatment option looks similar from one anxiety to another, it isn’t going to be the same. Each sufferer presents their own needs that must be taken into account. Each therapy isn’t going to work the same for each individual. Personalization of treatment is key in these situations.

Generalized Anxiety Disorder

The main features of Generalized Anxiety Disorder (GAD) are excessive anxiety and worry. The patients suffer from somatic anxiety symptoms as well as from restlessness, irritability, difficulty concentrating, muscle tension, sleep disturbances and being easily fatigued. Some patients may express constant worry that they or a relative will shortly become ill or have an accident.

Generalized Anxiety Disorder is a bit unlike the other anxiety disorders on this list. Those who suffer from GAD aren’t always able to give a reason for their symptoms. In fact, one of the symptoms is a general feel of restlessness or unease. They may also experience worry as one of the symptoms. Everyone worries from time to time but GAD causes the sufferer to internalize those worries and take them to an entirely new level.

They may think of them in an obsessive manner which will case a downward spiral of other symptoms such as a disturbance in sleep patterns. The treatments available for GAD are similar to those of OCD, medications and therapy, though in this case, the medications may be benzodiazepines and antidepressants rather than the run-of-the-mill SSRIs.

Cognitive behavioral therapy is used with GAD as well as relaxation techniques and mindfulness.

Obsessive-Compulsive Disorder (OCD)

OCD is characterized by recurrent obsessions or compulsions, or both, that cause impairment in terms of distress, time, or interference with functioning. Concerns involving contamination, harm, hoarding, and sexual, somatic and religious preoccupations are the most common obsessions. Compulsions include washing, checking, repeating, ordering, counting, hoarding and touching (rare).

Obsessive Compulsive Disorder technically has two components, the obsessions and the compulsions. Obsessions can encompass anything from a severe fear of germs to the placement of things around the home and many things in between. The compulsions are what the sufferer does to rid themselves of those obsessive thoughts. Someone who has obsessions about germs may ritually wash their hands or carry hand sanitizer everywhere they go.

Someone who has obsessive thoughts about the placement of objects might arrange and rearrange their belongings until they feel just right. These obsessions and compulsions can become very intrusive and disruptive to the sufferer’s daily life.

As far as treatments for OCD go, there are a couple. There are selective serotonin reuptake inhibitors such as fluoxetine sertraline. These medications are meant to help alleviate the symptoms for the sufferer so that they are at a manageable and less destructive level.

The other widely-used treatment is psychotherapy. With this you might run into cognitive behavioral therapy that will be used to help the sufferer essentially reprogram their response to obsessions and compulsions. For the most part, medications and therapies are used in tandem to get the best results.

Panic Disorder

Panic Disorder is characterized by recurrent panic attacks. Panic attacks are discrete periods of intense fear or discomfort, accompanied by at least four somatic and psychic symptoms (palpitations, sweating, trembling, dyspnoea, choking sensations, chest pain, nausea, abdominal distress, dizziness, feeling of unreality, fear of dying, etc.).

A panic attack reaches a peak within 10 min and lasts 30 – 45 min on average. Usually, the patient is afraid that he has a serious medical condition such as myocardial infarction.

Unlike the other anxiety disorders on this list, Panic Disorder rests solely on panic attacks. With many other anxiety disorders, panic attacks are just another symptom. When it comes to Panic Disorder, those attacks are the symptom.

Panic Disorder is characterized by recurrent panic attacks. The sufferer may experience heart palpitations or racing pulse, an intense fear and the feeling that they are hopelessly out of control.

There isn’t a rhyme or reason to many of these attacks so the sufferer is essentially lying in wait for the next one to come. Panic Disorder can be treated in many ways. The medications used are some that we’ve heard of such as benzodiazepines and SSRIs.

We are also introduced to serotonin norepinephrine reuptake inhibitors or SNRIs and beta blockers. These medications, as with OCD, are often used in conjunction with therapy to help maximize the usefulness of each.

Agoraphobia
About two-thirds of all patients with panic disorder suffer from agoraphobia, which is defined as fear in places or situations from which escape might be difficult or in which help may not be available in the event of having an unexpected panic attack. These situations include being in a crowd or standing in a line, being outside the home alone, or traveling in a bus, train or automobile. These situations are avoided or endured with marked distress.

Post-traumatic Stress Disorder (PTSD)

PTSD develops after a terrifying ordeal that involved physical harm or the threat of physical harm. The person who develops PTSD may have been the one who was harmed, the harm may have happened to a loved one, or the person may have witnessed a harmful event that happened to loved ones or strangers.

The condition is characterized by

  • recurrent and intrusive distressing recollections of the event
  • nightmares
  • a sense of reliving the experience with illusions
  • hallucinations
  • or dissociative flashback episodes
  • intense psychological or physiological distress at exposure to cues that resemble the traumatic event
  • avoidance of stimuli associated with the trauma
  • inability to recall important aspects of the trauma
  • loss of interest
  • estrangement from others
  • sleep disturbances
  • irritability
  • difficulty concentrating
  • hypervigilance
  • and exaggerated startle response.

The full symptom picture must be present for more than 1 month.

Post-Traumatic Stress Disorder can be diagnosed in anyone. For the most part, you have probably heard it when someone speaks about veterans or police officers. While those careers have a higher rate of PTSD, it is in fact true that anyone can be diagnosed with it. PTSD is the result of a very traumatic event or series of events.

This leaves the sufferer with flashbacks and night terrors where they feel as if they are right back in the event again. The sufferer may also suffer from panic attacks as well as phobias associated with people, places or even sounds. Medications such as fluoxetine venlafaxine may be used in the treatment of PTSD. Therapies such as prolonged exposure, cognitive processing therapy and brief eclectic psychotherapy may be utilized as well.

Again, this is a situation where the use of medications and therapy together can help give a better outcome than just one alone. It is important to note that those with PTSD can lash out in certain situations but there is no need to be afraid of the sufferers. There is nothing inherently dangerous about them. In fact, those with mental illness are exponentially more likely to be the victims of violent crimes than they are to be the perpetrator.

Anxiety Medications

  • Benzodiazepines: Xanax (alprazolam), Valium (diazepam), Klonopin (clonazepam), Ativan (lorazepam)
  • Antidepressants
  • Buspar (buspirone)
  • Propranolol
  • Gabapentin

Treating Anxiety in Substance Abusers

Given how common substance abuse is in psychiatric patients, it is often a tricky decision about prescribing potentially abusable drugs to substance users. In making these decisions, it is important to estimate how likely it is that a given patient will misuse a drug, either by abusing it or by giving or selling it to someone else.  There must be a balance of that estimate with the drug’s potential benefit for the patient.

A particularly common scenario is the patient with a history of substance abuse who suffers anxiety and is requesting benzodiazepines. While benzodiazepines are effective anti-anxiety medications for many patients, most guidelines tell providers to avoid prescribing them to substance abusers. The concerns are that the benzo high will remind patients of their substances of choice, and that benzo withdrawal symptoms will lead to old substance-abusing habits.

However, one review of the literature concluded that benzos can safely be prescribed for some alcoholics in recovery (Lingford-Hughes et al, 2002), and most psychiatrists can manage such patients by making sure that they do not escalate their doses and do not get early refills. Psychotherapy is always an option, and it can work well.

For example, a two-week pilot trial of cognitive behavioral therapy–based integrated treatment for panic disorder and alcohol abuse in 48 patients showed benefit over alcoholism treatment alone (Kushner et al, 2006). But assuming therapy has already been tried, what are some reasonable non-benzo approaches?

SSRIs/SNRIs and other antidepressants

Most substance abusers with anxiety will end up rotating through several SSRIs and SNRIs. These are robustly effective medications with few side effects, and we all have our own “go to” meds. Paroxetine carries the most FDA-approved indications for disorders on the anxiety spectrum, but it also is the most likely to cause sexual dysfunction, weight gain, and sedation.

Sertraline and escitalopram are good choices in terms of minimal side effects and few drug/drug interactions. The SNRIs, especially duloxetine, may be especially appropriate if your patient has a comorbid chronic pain condition, because both of these meds carry FDA indications for pain syndromes.

The newer antidepressant vilazodone was effective for GAD in one placebo-controlled trial (Gommoll et al, 2015).You might also consider mirtazapine (Remeron), effective in a small open-label study of GAD and also helpful for insomnia.

Bupropion, while not effective for anxiety disorders per se, is effective for anxiety when it is a symptom of depression—but watch out for its common early side effects of insomnia and jitteriness, and note that it is contraindicated in patients withdrawing from alcohol or other sedatives.

Buspirone

Buspirone has been around a long time, and many of your patients will say they’ve already tried it. Maybe they have, maybe they haven’t. Here are two tips to optimize patient response. First, don’t oversell it as a benzodiazepine substitute—it doesn’t work as quickly or as well, and patients expecting the benzo feeling will be disappointed and stop taking it. Second, get the dose high enough to be effective before throwing in the towel. A robust dose is 60 mg a day, split up either twice or three times daily. Dizziness and sedation may limit the dose.

Hydroxyzine (Atarax, Vistaril)

Some are surprised to hear that hydroxyzine has an FDA indication for anxiety (albeit an old one). It is effective—for example, in one large randomized placebo-controlled trial, patients with GAD randomly assigned to hydroxyzine 50 mg/day did just as well as those assigned to bromazepam 6 mg/day (bromazepam is a benzodiazepine approved in Europe; 6 mg is equivalent to about 10 mg of diazepam). Patients on the benzodiazepine experienced more sedation (Llorca et al, 2002).

Pregabalin (Lyrica)

Pregabalin is a Schedule V controlled substance (the same category as cough suppressants with codeine), so it might seem an odd choice for treating anxiety in patients with substance abuse histories. Wouldn’t it pour fuel on the fire? Apparently not. In fact, pregabalin has been compared with naltrexone as a treatment for alcohol dependence; in one small randomized controlled trial, pregabalin was as effective as naltrexone and led to greater improvement in anxiety (Martinotti et al, 2010).

Pregabalin’s efficacy for GAD (in the absence of substance abuse) is pretty well-established. Clinical trials have shown that the drug is as effective as lorazepam and alprazolam, and more effective than venlafaxine for GAD. Placebo-controlled trials have also shown that it is more effective than placebo for patients who have had only a partial response to SSRIs or SNRIs (for a recent review of these studies, see Reinhold & Rickels, 2015). Start at 100 mg QHS, and gradually titrate to 300 mg BID.

Pregabalin’s potential drawbacks in addition to its addictive properties include high rates of dizziness and sedation (20%–30% of patients), and an average weight gain of about 5 pounds after 4 weeks. There aren’t any drug-drug interactions currently noted for pregabalin.

Gabapentin (Neurontin)

Gabapentin was originally used to prevent seizures as an anti-epilepsy drug. Its off-label uses include treatment for anxiety disorders as well as withdrawal from alcohol or benzodiazepines. (The drug was once also touted as a treatment for bipolar disorder, but well-designed trials discredited this use.) One small placebo-controlled trial found gabapentin (average dose 2,868 mg/day) superior to placebo for social phobia, but the response rates were low (32% for gabapentin, 14% for placebo) (Pande et al, 1999).

For alcohol dependence, in one large double-blind trial, a rapid 4-day taper of gabapentin (from 1,200 mg/day to 800 mg/day) was more effective than a taper of lorazepam in terms of preventing relapse (Myrick et al, 2009). Common gabapentin side effects include dizziness and sedation, and there is increasing evidence that many patients abuse it for its sedative properties.

Quetiapine (Seroquel)

Quetiapine is hardly the first antipsychotic to be used or approved for anxiety. Stelazine (trifluoperazine) is approved for the short-term treatment of GAD, while Triavil (the combination of the antipsychotic perphenazine and the antidepressant amitriptyline) is approved for “depression and anxiety.” In addition, many clinicians use low-dose chlorpromazine (Thorazine) off-label for anxiety.

The advantage of quetiapine is that its efficacy evidence is more robust, with placebo-controlled trials of over 2,600 patients showing that the medication eases symptoms of GAD better than placebo, just as well as paroxetine, and better than escitalopram (for a review of these studies, see Gao et al, 2009). Lower doses of quetiapine XR, 50–150 mg QD, appear to be more effective than higher doses.

Quetiapine has not won FDA approval for GAD, probably because its disadvantages literally outweigh its advantages (it’s one of the worst antipsychotics in terms of weight gain and metabolic disturbances). Quetiapine, like gabapentin, has become a drug of abuse in some circles (Sansone & Sansone, 2010).
