Q

Clark’s CBT model for panic attacks?

A
  • The trigger can be external (eg crowds) or internal (eg heartbeat) – ‘selective attention’/ ‘hypervigilence’
  • The person misinterprets normal body sensations as meaning that a physical or mental disaster is imminent – ‘catastrophic misinterpretation’
  • The ‘fight or flight’ survival response produces more symptoms - which fuel the ‘vicious cycle’ of panic
  • attempts by the person to manage panic bring short term relief but make it worse in the long term (avoidance + safety behaviours)
