The incidence of epilepsy increases with age. With current demographic trends, this presents a healthcare challenge. We investigated the clinical spectrum of first seizures, evaluated neuroimaging and EEG findings, and determined clinical outcomes, including anti-seizure medication (ASM) response in older people. In addition, we sought to understand the relative effects of age and frailty on ASM response.

A retrospective single centre cohort study of 207 cases ≥60 years' old, 113 of whom were eventually diagnosed with a first seizure in a specialist epilepsy clinic.

65/113 (57.5%) presented with either focal aware or focal impaired awareness seizures. Stroke was the most common aetiological association (31.9%, 36/113), and odds of seizure recurrence did not significantly differ between aetiologies. 55/86 (64.0%) who started an ASM had no seizure recurrence. 14/48 (29.2%) who …
