PSY208 Unit II, Chapter 6: Panic, Anxiety, and their Disorders
SR 1 –
- The anxiety disorders have anxiety or panic or both at their core.
- They were initially considered a subset of the neuroses,
- But recent versions of the DSM-III and DSM-IV-TR have largely abandoned this term.
SR 2 – Fear or Panic
- Fear or panic is a basic emotion that involves activation of the fight-or-flight response of the autonomic nervous system.
SR 3 – Anxiety
-
Anxiety is a more diffuse blend of emotions that include:
- High levels of negative affect,
- worry about possible threat or danger,
- and the sense of being unable to predict threat or to control it if it occurs.
SR 4 -
- Anxiety and panic are each associated with a number of distinct anxiety disorder syndromes.
SR 5 – Specific Phobias
- With specific phobias, there is an intense and irrational fear of specific objects or situations;
-
When confronted with a feared object, the phobic person often shows activations of the fight-or-flight response, which is also associated with panic.
- Many sources of fear and anxiety are believed to be acquire through conditioning or other learning mechanisms.
- However, some people (because of either temperamental or experimental facts) are more vulnerable than others to acquiring such responses.
- We seem to have a biologically base preparedness to acquire readily fears of objects or situations that posed a threat to our early ancestors.
SR 6 – Social Phobias
- In social phobias, a person has disabling fears of one or more social situations usually because of fears of negative evaluations by others or of active in an embarrassing or humiliating manner,
-
in some cases a person with social phobia may actually experience panic attacks in social situations.
- We seem to have an evolutionary based predisposition to acquire fears of social stimuli signaling dominance and aggression from other humans.
- People with social phobias are also preoccupied with negative self-evaluative thoughts that tend to interfere with their ability to interact in a socially skillful fashion.
SR 7 – Panic Disorder
-
In panic disorder, a person experiences unexpected panic attacks that often create a sense of stark terror, which usually subsides in a matter of minutes.
- Many people who experience panic attacks develop anxious apprehension about experiencing another attack; this apprehension is required for a diagnosis of panic disorder.
- Many people with panic disorder also develop agoraphobic avoidance of situations in which they fear they might have an attack.
- The conditioning theory of panic disorder proposes that panic attacks cause the conditioning of anxiety primarily to external cues associated with the attacks, And conditioning of panic itself primarily to interceptive cues associated with the early stages of the attacks.
- The cognitive theory of panic disorder holds that this condition may develop in people who are prone to making catastrophic misinterpretations of their bodily sensations, a tendency that may be related to preexisting high levels of anxiety sensitivity.
- Other biological theories of panic disorder emphasize that the disorder may result from the biochemical abnormalities in the brain as well as abnormal activity of the neurotransmitters norepinephrine and serotonin.
- Panic attacks may arise primarily from the brain area called the amygdala, although many other areas are also involved.
SR 8 – Generalized Anxiety Disorder
-
In Generalized Anxiety Disorder, (GAD) a person has chronic and excessively high levels of worry about a numbers of events or activities and responds to stress with high levels of psychic and muscle tension.
- GAD may occur in people who have had extensive experience with unpredicted and/or uncontrollable life events.
- People with generalized anxiety seem to have schemas about their inability to cope with strange and dangerous situations that promote worries focused on possible threats.
- The neurobiological facter most implicated in generalized anxiety is a functional deficient in the neurotransmitter GABA, which is involved in the inhibiting anxiety in stressful situations;
- The limbic system is the brain area most involved.
SR 9 -
- Thus different neurotransmitters and brain areas are involved in panic attacks and generalized anxiety.
SR 10 – Obsessive-Compulsive Disorder (OCD)
- In obsessive-compulsive disorder, a person experiences unwanted and intrusive distressing thoughts or images that are usually accompanied by compulsive behaviors performed to neutralize those thoughts or images.
-
Checking and cleaning rituals are most common.
- Biological casual factors also seem to be involved in obsessive-compulsive disorder, with evidence coming from genetic studies, studies of brain functioning, and psychopharmacological studies.
- Once this disorder begins, the anxiety-reducing qualities of the compulsive behaviors may help to maintain the disorder.
SR 11 -
- Once a person has an anxiety disorder, mood-congruent information processing, such as attentional and interpretative biases, seem to help maintain it.
SR 12 -
- Many people with anxiety disorders are treated by physicians,
-
Often with medications designed to allay anxiety or with antidepressant medication that also have anti-anxiety effects.
- Such treatment focuses on suppressing the symptoms, and some medications have addictive potential.
- Once the medications are discontinued, relapse rates tend to be high.
SR 13 -
-
Behavioral and cognitive therapies have a very good track record with regard to treatment of the anxiety disorders.
- Behavior therapies focus on prolonged exposure to feared situations; with obsessive- compulsive disorder, the rituals also must be prevented following exposure to the feared situations.
- Cognitive therapies focus on helping clients understand their underlying automatic thoughts, which often involve cognitive distortions such as unrealistic predictions of catastrophes that in reality are very unlikely to occur.
- Then they learn to change these inner thoughts and beliefs through a process of logical reanalysis known as cognitive restructuring.
Key Terms
agoraphobia (P. 195) fear of being in places or situations where a panic attack may occur, and from which escape would be physically difficult or psychologically embarrassing, or in which immediate help would be unavailable in the event that some mishap occurred.
amygdala (P. 199) a collection of nuclei that are almond-shaped which lie in front of the hippocampus in the limbic system of the brain. It is involved in regulation of emotion and is critically involved in the emotion of fear.
anxiety (P. 181) a general feeling of apprehension about possible danger.
anxiety disorders (P. 180) an unrealistic, irrational fear or anxiety of disabling intensity. DSM-IV-TR recognizes seven types of anxiety disorders: phobic disorders (specific or social), panic disorder (with or without agoraphobia), generalized anxiety disorder (GAD), obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD).
anxiety sensitivity (P. 201) a personality trait involving a high level of belief that certain bodily symptoms may have harmful consequences.
blood-injection-injury phobia (P. 185) Persistent and disproportionate fear of the sight of blood or injury, or the possibility of having an injection. Afflicted persons are likely to experience a drop in blood pressure and sometimes faint.
compulsions (P. 211)overt repetitive behaviors (such as hand washing or checking) or more covert mental acts (such as counting, praying, saying certain words silently, or ordering) that a person feels driven to perform in response to an obsession.
fear (P. 181) A basic emotion that involves the activation of the “fight-or-flight” response of the sympathetic nervous system.
generalized anxiety disorder (GAD) (p.205) chronic excessive worry about a number of event s or activities, with no specific threat present, accompanied by at least three of the following symptoms: restlessness, fatigue, difficulty concentrating, irritability, muscle tension, sleep disturbance.
interoceptive fears (P. 205) fear of various internal bodily sensations.
neuroses (P. 180)
neurotic behavior (P. 180) anxiety driven, exaggerated use of avoidance behaviors and defense mechanisms.

obsessive-compulsive disorder (OCD) (P. 211) Anxiety disorder characterized by the persistent intrusion of unwanted and intrusive thoughts or distressing images; these are usually accompanied by compulsive behaviors designed to neutralize the obsessive thoughts or images or to prevent some dreaded event or situation.
panic (P. 181) A basic emotion that involves activation of the “fight-orflight” response of the sympathetic nervous system and that is often characterized by an overwhelming sense of fear or terror.
panic disorder (P. 194) Occurrence of repeated unexpected panic attacks, often accompanied by intense anxiety about having another one.
