Definition and symptoms of Anxiety
- Future-oriented mood state characterized by marked negative affect
- Includes somatic symptoms of tension
muscle tightness, tension headaches - Apprehension about future danger or misfortune exhibited through any of: behaviors, feelings, and thoughts
Definition and symptoms of Fear
- Present-oriented mood state characterized by marked negative affect
- Involves abrupt activation of the sympathetic nervous system
- Immediate fight or flight response to danger or threat
- Strong tendency to avoid or escape
signs of an anxiety disorder
- characterized by pervasive and persistent symptoms of anxiety and fear
- involve excessive tendencies to avoid and escape
- anxiety symptoms and avoidance cause clinically significant distress and impairment
Definition of a panic attack
- abrupt experience of intense fear or discomfort
- attacks occur (at least initially) out of the blue and are not cued by obvious triggers
Diagnosing panic disorder
- the presence of 4 or more of the 13 symptoms
- abruptly, reaching peak w/in 10 minutes
- at least 2 unexpected attacks are required
- at least one of the panic attacks must be followed by persistent concerns lasting at least one month about having another attack
Symptoms of a panic attack
1- palpitations, pounding heart, or fast heart rate
2- sweating
3- trembling and shaking
4- sensations of shortness of breath or smothering
5- feelings of choking
6- chest pain or discomfort
7- feeling dizzy, unsteady, lightheaded, or faint
chills or hot flashes
8- nausea or abdominal distress
9- derealisation (feelings of unreality) or depersonalisation (being detached from oneself)
10- fear of losing control or going crazy
11- paresthesias (numbness or tingling sensations)
12- fear of dying
13- chills or hot flashes
DSM-IV subtypes of panic attacks
Situationally bound (cued) = panic that occurs only in certain situations; expected
Unexpected (uncued) = panic that is not associated with specific situations; comes unexpectedly, “out of the blue”
Situationally predisposed = panic that may or may not occur in certain situations
diathesis-stress model for anxiety disorders
people inherit vulnerabilities for anxiety and panic, not anxiety disorders
stress and life circumstances activate the underlying biological vulnerability
Biological contributions to anxiety disorders
GABA, noradrenergic and serotonergic brain systems are implicated in anxiety
corticotropin releasing factor (CRF) and the HPA axis
limbic and the septal-hippocampal systems
amygdala
behavioural inhibition system (BIS)
fight-flight system
Freud’s perspective on anxiety
- anxiety is a psychic reaction to danger
- anxiety involves reactivation of an infantile fear situation
behaviouristic perspective on anxiety
anxiety and fear result from direct classical and operant conditioning and modelling
psychological perspective on anxiety
early experiences with uncontrollability and unpredictability
social perspective on anxiety
- stressful life events as triggers of biological and psychological vulnerabilities
- many stressors are familial and interpersonal
integrative perspective on anxiety
- biological vulnerability interacts with psychological, experiential, and social variables to produce an anxiety disorder
- consistent with diathesis-stress model
6 anxiety disorders
generalised anxiety disorder (GAD) specific phobias panic disorder with and without agoraphobia (PD) social phobia posttraumatic stress disorder (PTSD) obsessive-compulsive disorder (OCD)
Anxiety disorder changes from DSM 4 to DSM 5
DSM 5 moved PTSD and OCD to separate categories
Separation anxiety disorder added
Agoraphobia
fear or avoidance of situations or events where it might be difficult to escape or in which you would not have help available if you have a panic attack
If avoidance is persistent and pervasive the diagnosis is panic disorder with agoraphobia if it is not present than the diagnosis is panic disorder without agoraphobia
Proposal for the DSM 5 that panic and agoraphobia be considered separate disorders
Panic disorder facts and statistics
3.5% of the general population
2/3 of people with panic disorder are women
onset is often acute, usually beginning between 25 and 29 years of age
- 21% of Canadians aged 15+ experience at least one panic attack in their lifetime but only 1.5% of the Canadian population meets criteria for panic disorder
- Develops in late teen/early adulthood but treatment is usually not sought till 30s
- Women 2X more likely to be effected
medications for panic disorder
- target serotonergic, noradrenergic, and GABA systems
- SSRIs are currently the preferred drugs
relapse rates are high following medication discontinuation
psychological and combined treatments for panic disorder
cognitive-behavioural therapies are highly effective
Combined treatments do well in the short term
best long-term outcome is with cognitive-behaviour therapy alone
Specific phobias according to DSM
extreme and irrational fear of a specific object or situation
Exposure leads to anxiety response
recognition that fears are excessive
avoidance or endure with intense distress
interference with daily functioning
duration of 6+ months
Specific phobias stats and facts
11% of the general population meet diagnostic criteria for specific phobia
tend to be chronic , with onset beginning between 15 and 20 years of age
Considerably more common among women
Women have 90-95% animal phobias
Women have twice as many B-I-I phobias
subtypes of specific phobias
- Blood-injury-injection = vasovagal response to blood, injury, or injection
- Situational = public transportation or enclosed places; e.g., planes
- Natural environment = events occurring in nature; e.g., heights, storms
- Animal = animals and insects
- Illness = bodily related; e.g., developing cancer
- Other = do not fit into the other categories; e.g., fear of choking, vomiting
Specific Phobias Etiology
potential contributing factors
- Biological and evolutionary vulnerability
- Direct conditioning
- Observational learning
- Equipotentiality vs nonassociative models (the amount of learning required to develop that fear; the potential for that stimuli to become a phobia)
- Disgust sensitivity (the degree to which people are susceptible to being disgusted by a stimuli)
