  1. A Look At Panic Disorder with Agoraphobia Jennifer A. Roorda Laura Portman

  2. HISTORY • Symptoms are mentioned as early as the 1600’s (Clarke & Wardman, 1985) • First coined its name by Westphal in Germany during the 1870’s (Clarke & Wardman, 1985) • The name was used to describe an intense dread or anxiety from having to walk in certain outdoor locations

  3. HISTORY • In 1959 Klein studies effects of imipramine (McNally, 1994) • He finds it is effective against spontaneous panic attacks, but not against chronic anxiety • This implied a distinction between acute panic attacks and chronic anticipatory anxiety • This also prompted him to conceptualize agoraphobia as a consequence of panic

  4. More HISTORY • Drafts of ICD-10 treat agoraphobia as an independent disorder rather than a complication of panic disorder (Horwath, 1993) • First included in DSM III (Clarke & Wardman, 1985) • DSM-III-R puts agoraphobia in a larger category of panic disorder (Horwath, 1993)

  5. SYMPTOMS • Uncomfortable feelings growing into fear (Clarke & Wardman, 1985) • After succumbing to fears the day is spent feeling helpless and depressed • awareness of a “web of fear & a trap of unreason (Clarke & Wardman, 1985)

  6. SYMPTOMS- continued • Seven domains of Panic- agoraphobic symptoms (Cassano, et al., 1997) • panic symptoms • anxious expectation • phobic features • sensitivity to: reassurance, substances, general stress, separation

  7. SYMPTOMS- continued • Panic symptoms • panic attacks • according to DSM-IV, at least 4 out of 13 symptoms are required for diagnosis of panic attacks • limited symptom panic attacks may produce impairment similar to that of full-blown attacks • experiences most often associated with acute and intense anxiety: • unstable balance, sudden numbness, disorientation, “jelly legs,” tiredness, hypersensitivity to light, noise or heat

  8. SYMPTOMS- continued • Anxious expectation • the following may be experienced in the absence of panic attacks: • anticipatory anxiety • focused on the occurrence of typical or atypical panic symptoms • a persistent general state of alertness • associated with a sense of insecurity, impotence, or impending menace with respect to physical and psychic integrity

  9. SYMPTOMS- continued • Phobic and avoidant features • Avoidance • the attempt to cope with distress related to panic symptoms and anticipatory anxiety • this has temporary success in blocking panic • Illness phobia • misinterpretation of bodily sensations • fear and avoidance of medications • sleep phobia • fear of bad weather

  10. SYMPTOMS- continued • Sensitivity to reassurance • reliance on others as a means of coping with insecurity • lack of a well-developed capacity for autonomous action • leads to the continuous desire for help from others • may cause peculiar interpersonal behavior • repeated requests for medical examinations and tests

  11. SYMPTOMS- continued • Sensitivity to substances • chemicals and psychotropic medications • caffeine, recreational drugs, tricyclic antidepressants • these may trigger a full-blown panic attack • withdrawal symptoms may occur

  12. SYMPTOMS- continued • Sensitivity to general stress • stressful life events • symptoms may occur in relation to minor stressors, such as day to day family problems, sleep deprivation, or overwork • onset may occur even after the relief of tension

  13. SYMPTOMS- continued • Sensitivity to separation • dramatic reaction to loss (or the anticipation of it) • the end of a friendship or partnership, news of severe illness, sudden death of a loved one or pet. • Development of close and emotionally intense relationships characterized by dependence • often choose a partner on the basis of his or her high reliability as a companion.

  14. DIAGNOSIS - DSM IV • Dominated by recurrent unexpected Panic Attacks • At least one attack is followed by 1 mo. (or more) of one (or more) of the following: • persistent concern about having additional attacks • worry about the implications of the attacks or their consequences • a significant change in behavior related to the attacks

  15. DIAGNOSIS - DSM IV • It has been shown that panic attacks are not due to the direct physiological effects of a substance (drug abuse, medication) • The attacks are not better accounted for by another mental disorder, such as Social Phobia, Specific Phobia, Obsessive-Compulsive Disorder, Posttraumatic Stress Disorder, or Separation Anxiety Disorder

  16. DIAGNOSIS - DSM IV • The presence of Agoraphobia is evident when: • There is anxiety about being 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 or situationally predisposed panic attack. • Fears include being outside the home alone; being in a crowd or standing in line; being on a bridge; & traveling in a bus, train, or car. • Situations that have potential for causing attacks are avoided, or endured with great anxiety about having a panic attack

  17. DIAGNOSIS- continued • There tends to be a phobic dependency on special people • this makes it easier to enter public arenas; fears are eased (Clarke & Wardman, 1985) • Some believe that agoraphobia precedes the onset of panic disorder • this is due to reports of patients who had their first attack in an agoraphobic situation • this was found more often in patients with panic disorder without agoraphobia (Fava, 1993).

  18. ETIOLOGY • Agoraphobia is one of the most prevalent of all clinical phobias (Pollard, 1989) • Occurs at a frequency of 6 in 1000; makes up 50-80% of phobics seeking assistance (Goldstein, 1982) • Begins suddenly between the ages of 18 and 31 (thirteen percent of cases begin after age 40; it is least common at age 65 and above) (Clarke & Wardman, 1985; McNally, 1994)

  19. ETIOLOGY- continued • 95% of unexpected attacks start after a great stress occurs (Clarke & Wardman, 1985) • 75% of cases are women; men are less likely to admit to weakness (Clarke & Wardman, 1985) • in addition, men must leave home to work (can act as therapy), while many married women can stay home or rely on a friend

  20. ETIOLOGY- DSM IV • Lifetime prevalence: 1.5% - 3.5% One year prevalence: 1 - 2% • Development of agoraphobia is usually within one year of the occurrence of recurrent panic attacks • 1st degree biological relatives have a 4-7x’s greater chance of developing agoraphobia • Major depression often occurs in panic disorder patients (50-60%)

  21. ETIOLOGY- continued • 70% of 130 patients at an anxiety disorders research clinic were also diagnosed with at least one additional but secondary axis I diagnoses (Sanderson, et al., 1990) • The most common additional diagnoses are simple and social phobia • Most patients report that onset occurs most often during stressful life events

  22. ETIOLOGY- continued • Socioeconomic status of sufferers tends to be low • the less educated receive lower level jobs and are thus poorer financially. This leads to more serious symptoms (Chambless &Goldstein, 1982). • Personality type tends to be dependent • this can be caused by either: • growing up in an overprotective family or • having an unstable family life (Lilienferd, 1997)

  23. ETIOLOGICAL THEORIES • Biological theory (Davison & Neale, 1998) • overactivity in the noradrenergic system, specifically in a nucleus in the pons called the locus ceruleus • yohimbine, a drug, can stimulate activity in the locus ceruleus and can elicit panic attacks in patients with panic disorder • however, recent research is not consistent with this view. Drugs that block firing in the locus ceruleus are not effective treatments.

  24. ETIOLOGICAL THEORIES-cont • Panic disorder is linked to hyperventilation due to activated autonomic nervous system • lactate can also produce panic; the level may become elevated in patients with panic disorder and chronic hyperventilation • labs have found that increased levels of CO2 can cause a panic attack: thus oversensitive CO2 receptors could stimulate hyperventilation. • These findings occurred in 1 out of every 24 attacks • This is not a concrete theory

  25. ETIOLOGICAL THEORIES-cont • Physiological theory (Davison & Neale, 1998) • fear-of-fear hypothesis • a fear of having an attack in public • unexplained physiological arousal in someone who is fearful of such sensations leads to panic attacks • control hypothesis • fear of losing control in public • fear of embarrassment

  26. TREATMENTS • Drugs (Davison & Neale, 1998) • Benzodiazepines • example: alprazolam • these have been found to have some success, but must be continued otherwise symptoms will return if stopped • However, studies show that these have less long lasting effects on patients than cognitive-behavioral treatments (Brown & Barlow, 1995).

  27. TREATMENTS- continued • Tricyclic antidepressants (Chambless & Goldstein, 1982) • antidepressants block spontaneous panic attacks • as of 1982, the FDA had not accepted panic attacks as an indication for antidepressants • Example: imipramine (Mavissakalian, 1992) • dosage should be carefully monitored since panic disorder patients are sometimes very sensitive to drug use (Swinson, 1992) • Along with use of this drug, persuasion, support, or minor tranquilizers are often required to help extinguish anticipatory anxiety.

  28. TREATMENTS- continued • Systematic desensitization (Chambless & Goldstein, 1982) • patients are trained in muscular relaxation • they gradually move up a hierarchy of anxiety arousing situations while remaining relaxed • Either imagination or in vivo can be used • in vivo tends to be most successful • Flooding (Chambless & Goldstein, 1982) • maximize anxiety throughout treatment • this leads to extinction

  29. TREATMENTS- continued • Self-management Procedure (Jacobson and Hollon, 1996) • a combination of flooding followed by self-observation • this is more effective than any single treatment • a viable alternative to drugs • Relaxation Training (Barlow, 1988) • combination of cognitive and behavioral intervention and exposure to internal cues that trigger panic • After two years, this was shown to have great success

  30. PROGNOSIS • 60% of patients completing behaviorally based treatment show signs of improvement (Wade, et al., 1993) • According to DSM-IV, 6 - 10 years after treatment: • 30% are well • 40 - 50% are improved but symptomatic • 20 - 30% have symptoms that are the same or slightly worse
