Syncope in older adults is common, heterogeneous, and frequently misclassified as an unexplained fall, leading to injury, fear of recurrence, and costly, low-yield testing and hospitalization. The 2018 European Society of Cardiology (ESC) Guidelines emphasize structured initial evaluation (history with witnesses, orthostatic blood pressure, and 12-lead ECG), risk-feature-guided disposition, and targeted second-line investigations rather than routine neuroimaging or carotid duplex ultrasound. We performed a structured narrative review anchored to the ESC 2018 Guidelines, searching MEDLINE/PubMed up to February 2026 for randomized trials, observational cohorts, and systematic reviews with substantial representation of adults aged ≥65 years and extracting geriatric-relevant outcomes including injury, falls, admission, arrhythmic diagnoses, and short-term serious events. Evidence since 2018 supports the enduring value of the ESC 2018 Guidelines’ framework but highlights the need for geriatric adaptation: repeated orthostatic phenotyping (including post-prandial and delayed hypotension), systematic deprescribing, and explicit integration of frailty, cognition, and trauma risk into disposition decisions. Post-2018 data strengthen mechanism-based strategies, including earlier implantable loop recorders with remote monitoring and selective pacing for tilt-induced asystolic reflex syncope, while cardioneuroablation remains investigational for most elders. We propose a pragmatic pathway prioritizing diagnostic yield, minimizing low-value testing, and aligning interventions with patient goals and functional outcomes to reduce recurrences and support safer transitions.
