Can a seizure condition be genetic in an elderly person?

Question

Hello doctor,

My father is 73 and recently had his first seizure. It has been scary for all of us. Can a seizure condition be genetic in a senior patient at 73, or is it more likely to be related to something new, such as a stroke, medications, or age-related changes in the brain? There is a family history of epilepsy, but he had been fine all his life until now.

Tests are ongoing, and the waiting is stressful. If it is genetic, does that change the treatment or outlook? We are anxious about his safety, driving, independence, and whether this means long-term decline or something that can be controlled well.

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

When seizures start for the first time at age 73, doctors usually investigate new causes such as stroke, age-related brain changes, medication side effects, infections, or metabolic problems, rather than assuming a genetic epilepsy.

A family history of epilepsy is still worth mentioning to his medical team, but it is less common for a purely genetic seizure disorder to first appear this late in life. The tests currently being done, such as brain scans, blood tests, and an EEG (electroencephalogram), are important because they can help identify a treatable cause.

Treatment and outlook depend mainly on what those tests show. Many older adults with new-onset seizures respond well to anti-seizure medications and can remain independent.

For now, safety is important. He should avoid driving, swimming alone, climbing heights, or operating dangerous machinery until his doctors advise otherwise.

A new seizure diagnosis does not automatically mean dementia, major decline, or loss of independence. In many cases, seizures can be controlled effectively once the underlying cause is identified and treated. Kindly consult a neurologist for further evaluation and guidance.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.
