Syncope in the elderly: diagnosis, evaluation, and treatment

Area of Science:

• Geriatrics
• Cardiology
• Neurology

Background:

• Syncope is notably more prevalent in older adults compared to other age groups.
• Age-related physiological changes (heart rate, blood pressure, baroreflex sensitivity, cerebral blood flow) and comorbidities increase syncope susceptibility.
• Assessing syncope in the elderly is complicated by factors like multiple diagnoses, polypharmacy, comorbidities, amnesia, lack of witnesses, falls, and cognitive impairment.

Purpose of the Study:

• To highlight the increased incidence and complex assessment of syncope in the elderly.
• To explore the link between cardiovascular risk factors, syncope, and cognitive impairment/dementia.
• To emphasize the broader implications of managing cardiovascular causes of syncope in older individuals.

Main Methods:

• Review of age-related physiological changes and comorbidities contributing to syncope.
• Analysis of factors confounding syncope assessment in older populations.
• Examination of the association between cardiovascular risk factors and dementia, specifically bradyarrhythmia.

Main Results:

• Older individuals face unique challenges in syncope evaluation due to multiple confounding factors.
• Cardiovascular risk factors, such as bradyarrhythmia, are implicated in both syncope and dementia.
• Interventions for cardiovascular causes of syncope can yield benefits beyond fall reduction, potentially impacting cognitive health.

Conclusions:

• Effective management of syncope in the elderly requires addressing age-related physiological changes and comorbidities.
• Early detection and intervention of cardiovascular risk factors may mitigate syncope, falls, and cognitive decline.
• Treating cardiovascular disorders causing syncope in older adults offers a multifaceted approach to improving overall health and preventing dementia.
