Abstract
OBJECTIVES: To evaluate the prevalence of cognitive impairment (CI), including mild CI and dementia, in elderly patients with syncope and unexplained falls. In this population, we compared the use of the Mini-Mental State Examination (MMSE) with a cognitive screening test that assesses executive dysfunction typical of subcortical (vascular) CI, that is, the Montreal Cognitive Assessment (MoCA). DESIGN: Observational cohort study. SETTING: Outpatient fall and syncope clinic. PARTICIPANTS: Consecutive patients aged ≥65 years with syncope and unexplained falls without loss of consciousness. MEASUREMENTS: Baseline characteristics, functional status, MMSE, MoCA, and magnetic resonance imaging scans of the brain. MAIN OUTCOME: prevalence of CI, comparing the MMSE with the MoCA. CI was defined as an MMSE/MoCA score <26. SECONDARY OUTCOMES: MMSE/MoCA overall and subdomain scores, Fazekas and medial temporal lobe atrophy scores. RESULTS: We included 200 patients, mean age 79.5 (standard deviation 6.6) years (Syncope Group: n = 101; Fall Group: n = 99). Prevalence of CI was 16.8% (MMSE) versus 60.4% (MoCA) in the Syncope Group (P < .001) and 16.8% (MMSE) versus 56.6% (MoCA) in the Fall Group (P < .001). Prevalence of CI did not differ between the Syncope Group and Fall Group with either method. Executive dysfunction was present in both groups. CONCLUSION: CI is as common in elderly patients with syncope as it is in patients with unexplained falls, with an overall prevalence of 58%. The MMSE fails as a screening instrument for CI in these patients, because it does not assess executive function. Therefore, we recommend the MoCA for cognitive screening in older patients with syncope and unexplained falls.
