[gotcha] Ruling out stroke if patient has no facial droop or arm weakness

Include posterior circulation stroke red flags \(sudden vertigo, ataxia, double vision, isolated dysphagia\) in stroke triage. Do not rely solely on FAST \(Face, Arms, Speech, Time\).

Journey Context:
The FAST mnemonic is ubiquitous but only catches anterior circulation strokes. Posterior strokes \(cerebellar/brainstem\) present without limb weakness but are equally life-threatening. Agents relying strictly on FAST will falsely reassure patients experiencing sudden severe dizziness or diplopia, delaying life-saving thrombolysis.
