Commonest Cause for New-Onset Seizures in Elderly
The most common cause for new-onset seizures in individuals older than 65 years is cerebrovascular disease.
Cerebrovascular disease encompasses conditions like ischemic strokes (blockages) and hemorrhagic strokes (bleeding) in the brain. These events damage brain tissue, altering its normal electrical function and increasing the likelihood of seizure activity.
As the population ages, the incidence of cerebrovascular events rises significantly, making it the leading etiology for first-time seizures in this demographic. While other factors can cause seizures:
- Trauma: More common in younger individuals.
- Tumors: Less frequent than cerebrovascular events in the elderly onset group.
- Degenerative diseases: Can be associated with seizures but are not the primary cause as often as stroke.
Therefore, cerebrovascular disease is identified as the predominant factor for new-onset seizures in patients over 65.
