Epilepsy with onset at over 50 years of age: clinical and electroencephalographic characteristics
Epilepsy in older individuals has an elevated incidence. The objective of the present work was to evaluate the clinical, EEG and brain imaging aspects in patients showing late-onset epilepsy. Fifty-five patients with late-onset epilepsy (older than 50 years) were evaluated. They were composed of two groups according to the onset age of the epilepsy seizure (ES): 51-60 (G51-60) and over 60 (G60+) years. Focal ES predominated although they were less frequent in G60+. The occurrence of status epilepticus was high and more frequent in G60+ whereas seizures in series predominated in G51-60. Symptomatic epilepsy was more frequent and the vascular etiology predominated. Epileptiform activity was associated with a greater number of ES, and background activity abnormalities were more frequent in G60+. In conclusion, epilepsy with onset at over 50 was predominantly focal and symptomatic, with a high occurrence of status epilepticus and of seizures in series.
