Panic disorders Flashcards
Define panic attacks
Sudden onset of intense panic in which multiple physical symptoms of stress occur, often with feelings that one is dying
Define panic disorder
Panic attacks occur frequently enough to cause the person difficulty in adjusting to daily life
Signs of a panic attack
1) sweating
2) racing heart
3) chest pain
4) shortness of breath
5) dizziness
6) nausea
7) hot flashes/ chills
8) trembling
9) terror
10) desire to escape
DSM-5 criteria for a diagnosis of panic disorder
A) recurrent unexpected panic attacks
B) At least one of the attacks have been followed by 1 month or more of one or both of the following
1) persistent concern or worry about additional panic attacks or their consequences
2) significant maladaptive change in behaviour related to the attacks
C) the disturbance is not attributable to the direct physiological effects of a substance
D) the disturbance is not better accounted for by another mental disorder
Define Agoraphobia
• fear of leaving one’s familiar surroundings because one might have a panic attack in public
• agoraphobia occurs in 1/3 of sufferers of panic disorder
DSM-5 criteria for diagnosis of agoraphobia
A) marked fear or anxiety about at least one situation from two or more of the following five groups of situations:
- public transportation
- open spaces
- being in shops, theatres, or cinemas
- standing in line or being in a crowd
B) the individual fears these situations due to thoughts that escape might be difficult or help might not be available in the event of panic- like symptoms or other incapacitating symptoms
C) the agoraphobic situation also at always provoke fear or anxiety
Aetiology- brain structures
• amygdala(emotional processing of threats)
• hippocampus (learning of emotional responses, memories of panic attacks, anticipatory anxiety)
• locus cereulus (major source of NE)
Aetiology- Noradrenergic system
• increased activity in the Noradrenegic system
- increased arousal, fear or anxiety
- support from PET scan studies
- deviancy in gamma- amino butyric acid (GABA) neurons
- role of GABA neurons- inhibits noradrenergic activity
Aetiology- hyperventilation
• a rapid form of breathing resulting in ventilation exceeding metabolic demand and has a result of lowering carbon dioxide levels
- upsets the balance and gases in the lungs
- low carbon dioxide levels in the lungs and lead to feelings that mimic a panic attack
Aetiology- anxiety and sensitivity
• anxiety sensitivity
- fear of anxiety symptom/ related sensations
• anxiety sensitivity index
- physical
- psychological
- social concerns
• ASI - risk factor for panic attacks and panic disorder
- physical concerns dimension is a significant predictor of panic disorder symptoms
Aetiology- Introceptive conditioning
Classical conditioning of panic response in response to internal bodily sensations(intorceptive cues)
- can lead to agoraphobic avoidance
- safety behaviours can maintai introceptive conditioning
- activities deployed to avoid perceived catastrophic outcome.
Aetiology- catastrophic misinterpretations
- catastrophic misinterpretations of bodily sensations. (clark 1986)
-individuals attend to bodily sensations more than others - catastrophic beliefs increase anxiety and arousal
- catastrophizing bodily sensations can create a visious cycle of anxiety and lead to panic attacks
-typical to panic disorder
Ohst-Tuschen-caffier
Results: Catastrophic misinterpretation ore common in panic disorder than other anxiety disorders.
Study: Ppts with panic disorders, other anxiety disorders, and healthy control. Experimental group watched a suspenseful film to induce physiologocal arousal, then completed the BSIQ-FR measure. Panic disorder ppts exhibited more catastrophic misinterpretations, but only after physiological arousal was triggered.
Treatment- relaxation
Psychoeducation
-nature of panic disorders and hyperventilation.
Relaxing and breathing retraining.
- education about the physiological effects of hyperventilation and practice in slow breathing
- the client learns to control breathing through repeated practice using muscles of the diaphragm, rather than the chest.
Treatment - CBT
- Introceptive exposure to reduce fear of harmless bodily sensations(carrying out behaviour that induce physical sensations of panic attack)
- cognitive reconstructing therapy(identify and challenge faulty threat perceptions)
- prevention of ‘safety’ perceptions that may maintain attacks and acoid disconfirmation of faulty beliefs.
