“…The proportion of patients with unexplained syncope steadily increased with age, reaching 54% in the elderly group. Conversely, Dougnac and colleagues 4 and Kapoor 10 found a higher ratio of unexplained syncope in young vs elderly patients. Higher rates of syncope of unknown cause in our study may be related to differences in demographics or definitions used.…”

“…Our knowledge of syncope stems from various studies, many of which are small, retrospective, and referral based and include patients of all ages. Previous studies that addressed the age‐related differences in syncope presentation and management 4,8 compared “young” and “old” patients with arbitrary division between these 2 groups. Adult patients younger than 35 years form a well‐characterized group of a predominantly vasovagal syncope with an excellent prognosis.…”

The authors explored the differences in clinical presentation, etiology, mortality, and recurrences of new-onset syncope in 502 patients across 3 age groups: middle-aged (36-60 years), older (61-75 years), and elderly (older than 75 years). Clinical features of syncopal episodes were similar except for more frequent presyncopal episodes in patients older than 75 years. Yield of diagnostic tests was similarly low except for higher incidence of positive tilt-table test (60%) in older patients. Syncope remained unexplained more frequently in the elderly (54% vs 37% in middle-aged and 43% in older adults, P=.01). Syncope recurrence was higher in the middle-aged and elderly groups. Overall mortality for the 3 age groups was similar to that recorded in the general population after adjustment for age and comorbidities. Etiology of syncope was not associated with age- and comorbidity-adjusted all-cause mortality. Cardiovascular mortality was significantly higher in patients with cardiogenic syncope (adjusted hazard ratio, 2.44; P=.044).

“…In a series of 146 patients admitted for syncope, 2/3 were aged 65 years and older. 21 A specific etiology could be established in 62%, and 3/4 of these were cardiovascular in origin. Inhospital mortality was 2.1% and mortality at the end of the approximately 2-year follow-up period was 18.1%.…”

“…This suggests that syncope is more likely related to cardiovascular mechanisms in this age group, and that seizures may be less common than previously suggested. In a series of 146 elderly patients with syncope, Dougnac et al (1991) demonstrated a cardiovascular origin in 75% of cases. There was a 2-year mortality of 28.3% in the group of patients older than 65 years with syncope, highlighting the importance of a correct diagnosis.…”

The EEG is a common test ordered in the elderly population for a variety of indications such as syncope, encephalopathic states, transient unresponsive episodes, and clinical seizures. The authors analyzed the spectrum of EEG abnormalities in a series of 300 homogenous elderly patients in the southern region of Ireland who were referred for the above indications. Generalized slowing was seen in 30.7% and focal abnormalities in 9% of records. Thirteen records demonstrated focal sharp waves and one record showed generalized epileptiform discharges. Two records with seizures were identified, both with nonconvulsive status epilepticus. The incidence of ECG abnormalities was high (23%). In patients referred for syncope, the incidence of EEG epileptiform abnormalities (sharp waves) was 3%, in contrast to previous reports of 49%. In patients older than 80 years (the "old old"), EEG abnormalities were more common. The yield of the EEG for common referrals such as syncope, encephalopathy, and transient unresponsiveness is low for focal abnormalities. Electrocardiographic abnormalities were common and should be identified and treated appropriately.
