“What if it’s a brain tumour?”

Vasovagal syncope is a POSITIVE clinical diagnosis from the history — prodrome (hot, nauseated, tunnel vision, ringing ears), classic triggers (venepuncture, prolonged standing, heat, postural on illness), rapid full recovery — not a diagnosis of exclusion that requires scanning. The skill set is twofold. Clinically: make the diagnosis confidently while actively excluding (out loud) the red flags that mandate cardiac or neurological work-up — exertional/no-warning syncope, palpitations-then-collapse, syncope lying down, family history of young sudden death, seizure features. Communicationally: the real presentation is HEALTH ANXIETY, signposted and triggered by a ward patient her age with a brain tumour. Reassurance here is a skilled task — specific, evidence-based, warm — not "it’s just a faint". Explain why a scan would harm not help, find and address the specific fear and the life-shrinking avoidance, give vasovagal self-management (ESC 2018, international) and accurate driving advice (DVLA, September 2025: Group 1 need not notify for typical vasovagal syncope with an avoidable trigger when standing), offer NHS Talking Therapies for the health anxiety (stepped care; CG123 withdrawn 2024), and safety-net precisely so reassurance is safe.
