Episode notes
Eye Flashes Led To TIA Workup And MRI
- Noreen described a sudden visual 'camera flashes' episode prompting A&E and TIA clinic visits.
- MRI showed small possible brain damage and she was placed on high‑dose aspirin pending cardiology review.
Autonomic Dysfunction Is Not One Thing
- Autonomic dysfunction is a heterogeneous "grab bag" that affects many systems, not a single disease.
- POTS is defined physiologically by excessive orthostatic heart-rate increase without orthostatic hypotension and positional symptoms.
Symptoms Are Driven By Sustained Upright Stress
- POTS symptoms worsen with prolonged upright posture rather than transient position changes.
- Heat, standing duration and activities raising the arms additively worsen orthostatic intolerance.
