Anxiety Flashcards
(38 cards)
Is the experience of anxiety in abnormal anxiety different to the normal experience of anxiety?
No- not qualitatively different
BUT excessive or inappropriate occurence
Which systems are involved in the experience of anxiety
- Physical- sympathetic nervous system (sweating, heart rate) mobilises resources to deal with threat
- Cognitive- threat perception, appraisal, attentional shift and hypervigilence- difficulty concentrating on other info
- Behavioural- avoidance, agression
Eliciting conditions in normal anxiety
Objective threats: physical or social
Specific ‘prepared’ stimuli (Seligman)- evolutionary e.g. insects
Novel Stimuli
Process of Anxiety
Threat appraisal-> expectancy of harm-> elicits anxiety
What underlies threat appraisal? And what gives rise to these biases?
Perceived probability and cost of threat Past experience (conditioning) Observational learning and Instruction
Trait anxiety- individual differences
Tendency to perceive threat in ambiguous situations
Intensity and duration of the anxiety response
(Inappropriate or excessive occurrence)
Overestimation of cost or probability of harmful outcome
Main overestimation for physical and social fears
Physical: overestimation of probability
Social: overestimation of cost
What characterises Anxiety Disorders?
Internal dysfunction- anxiety in situations that aren’t objectively dangerous
Socially inappropriate/harmful- interferes with everyday social or occupational activities- dysfunctional
Categorised according to focus of anxiety
DSM-IV Anxiety Disorders
Separation Anxiety Disorder Specific Phobia Social Phobia- fear of neg. social eval. Generalised Anxiety Disorder Panic Disorder (with or without agoraphobia) Posttraumatic Stress Disorder Acute Stress Disorder Obsessive- Compulsive Disorder
DSM-V Anxiety Disorders
Separation Anxiety Disorder (child or adult) Selective Mutism Specific Phobia Social Anxiety Disorder Panic Disorder Agoraphobia Generalised Anxiety Disorder
Differences between the DSMs
Selective Mutism added
Agoraphobia its own disorder
PSTD- in own chapter: Trauma- and Stressor-Related Disorders. with Acute, Adjustment, Reactive Attachment Disorder and Disinhibited Social Engagement
OCD- in own chapter with trich (used to be with gambling), hoarding, excoriation (new to DSM), body dysmorphic (used to be in somatoform disorders)
What are anxiety disorders comorbid with?
each other, depression and substance use
What are the underlying vulnerabilities?
Generalised Biological: genetics, neuroticism- genetic loading
Generalised Psychological: trait anxiety, perceived lack of control, depression
Specific Psychological: past experience, observation or instruction
Biological Treatments- don’t treat underlying disorder, just symptoms
Barbiturates (Amobarbital, Phenobarbital)- used to use (dangerous)
Quick acting, but relapse very common (80-90%)
Highly addictive, can lead to OD, interact with alcohol
Benzodiazepines (Valium, Xanax, Rohypnol) Quick acting, but relapse very common
Less addictive, but interact with alcohol
SSRIs (antidepressants, e.g., Prozac, Zoloft) Slower acting
Fewer side effects
Relapse common (20-60%)
CBT aims:
Reduce biased threat appraisal
Increase biased coping appraisal
Cognitive Techniques
thought-diaries to identify automatic thoughts
thought challenging: socratic questioning, evidence against, pros and cons of having the thought/ belief
Behavioural Techniques
Exposure to stimuli (reduce probability of harm) and outcomes (reduce judgements of cost)
in vivo vs imaginary and flooding vs systematic desensitisation
Do clinicians still treat PTSD and OCD like anxiety disorders
Yes, the distinction isn’t too important- closely related to anxiety
Required symptoms for Panic Attack
4 (or more): heart racing, sweating, trembling, shortness of breath, feelings of choking, chest pain, nausea, dixxiness, chills or heat sensations, paresthesias (numbness or tingling), derealization (feelings of unreality) or depersonalization (detached from oneself), fear of losing control, fear of dying
When do Panic Attacks occur?
Can occur in a terrible situation- normal.
Can occur in any anxiety disorder and some others
Particularly, specific and social phobias and PTSD- in these cases they are CUED by something
UNCUED occur in Panic Disorder
How many unexpected (uncued) panic attacks are needed for Panic Disorder Diagnosis?
2
Panic Disorder Criteria
At least two unexpected panic attacks
Persistent concern or worry about additional
panic attacks or their consequences
A significant maladaptive change in behavior related to the attacks
Symptoms persist one month or more
Its the catastrophic misinterpretation of sensations that causes a full blown attack. Fear of lack of control
Prevalence of Panic Disorder
Median age of onset
Course
Comorbidity
12-month prevalence: 2-3% Lifetime prevalence: 3.5-4.7% 20-29 years chronic but waxing and waning Other anxiety disorders, alcohol use and depression 10-65%
Specific Phobia prevalence
7-9% lifetime prevalence. Less than 1% seek treatment
