Panic like experiences can include a sudden surge of fear, racing heart, breathlessness, dizziness, shaking, sweating, nausea or a sense of unreality. A guide cannot diagnose panic disorder, determine a subtype or establish why an episode occurred. An assessment can consider the pattern, physical health, sleep, substances, medication, stress, avoidance and the wider context. Descriptions without self diagnosis Some attacks may seem linked to a setting or sensation; others may feel unexpected or happen on waking. These descriptions can guide a conversation, but they do not establish a diagnosis or decide the appropriate support. Nocturnal symptoms, limited symptom episodes and derealisation can be distressing and also need individual context rather than an online conclusion. Medical boundaries Chest pain, breathlessness, fainting, new neurological symptoms, severe physical change or a first episode with concerning symptoms should not be automatically attributed to panic. Seek appropriate medical advice, particularly when symptoms are new, severe, changing or worrying. A therapy guide cannot exclude a physical cause, advise on medication or replace urgent assessment. CBT based support and clinician led safeguards Where clinically appropriate, CBT based support may explore interpretations of bodily sensations, avoidance, reassurance seeking, sleep and routines. Behavioural experiments, interoceptive work or exposure based work should be planned collaboratively with an appropriately trained clinician, not used as self directed online instructions. The pace and focus depend on assessment, health, risk and the person’s goals. Urgent safety boundaries If you cannot keep yourself safe, have thoughts of harming yourself, experience psychosis, severe agitation, confusion or a sudden marked change in mental state, seek urgent help. In immediate danger, call 999 or attend A&E. Frequently asked questions Does a panic attack mean panic disorder? No. An episode alone cannot establish a diagnosis. Can I use exposure exercises from the internet? Exposure based work should be planned with an appropriately trained clinician.
