First Possible Seizure After 40: What to Do and Record

After 40, 50 or 60, a first possible seizure can come without warning and with no history. In that moment nobody holds your hand, and there is no checklist handed to you on paper. It matters for the family who may have watched. You write down what they saw, and you keep how you feel after in the symptom diary in Sam, where your symptom days come together in the monthly report.

What the doctor needs to know

For a proper assessment, a description written soon after the event is worth more than any later memory. Note when and where it happened, what you felt, and how long it lasted. A good list looks like this:

• The date and time.
• The place, and what you were doing.
• What you felt before, for example an odd feeling or a smell.
• What happened, in order.
• How long it lasted.
• How you felt after, and how long you needed to recover.

Write what you experienced in your own words. You do not need medical terms. "I do not know" is a valid answer to record.

The witness report

Many people do not remember the seizure itself afterwards. Then what others saw counts. Ask each person who was there.

Their account adds to your own. Useful questions are:

• What did the person look like, and what was visible?
• Did they respond when you spoke to them?
• Was the gaze fixed, or were there jerks or stiffening?
• Was there a fall or an injury?
• How long did the whole thing last?

Ask the person to write it down, or keep their words. You bring this to the appointment.

A single seizure is not yet epilepsy

A single unprovoked seizure is usually not epilepsy yet. The NHS says having a seizure does not always mean you have epilepsy, because seizures can have other causes. A diagnosis of epilepsy usually follows more than one unprovoked seizure, or when tests show a higher risk of more seizures. That is a medical judgement; no app and no text can make it.

At the same time, first seizures are not rare in older age. Older adults account for about a quarter of first-time seizures, according to AARP. Stroke and other blood-vessel problems in the brain are a common cause of new seizures in later life. That is why a doctor visit matters so much: it checks whether a treatable cause lies behind the event.

Not everything that looks like a seizure is one. Blood sugar, circulation or heart rhythm can look similar. Get it checked by a doctor. The difference between a seizure and fainting is a separate topic in Seizure or fainting?.

See a specialist soon, and check the driving rules

After a first possible seizure, prompt assessment is recommended, usually with a neurologist. The doctor decides which checks follow, such as an EEG, an ECG or a scan. For help preparing, see questions for the neurologist: a checklist.

One topic may surprise you: driving can be re-assessed after such an event. In Great Britain you must stop driving straight away and tell the DVLA; Northern Ireland has its own licensing agency, the DVA. In the US, rules depend on your state. So do not drive until the licensing authority and your doctor say you may. How long the pause lasts in your case is for you to discuss with your doctor and the licensing authority. This is general information, not legal advice. Check GOV.UK, the DVA in Northern Ireland or your state's DMV for the rules that apply to you. The risk of another seizure is greatest in the first two years, the American Academy of Neurology notes.

When to call emergency services now

Some situations are an emergency. Call your local emergency number (112 in the EU, 999 in the UK, 911 in the US) when:

• The seizure lasts longer than is usual for the person, or longer than five minutes if you do not know how long theirs usually last.
• Several seizures follow without the person recovering.
• It is the first seizure.
• The person is injured.
• Breathing becomes difficult, or the person does not wake again.

Sam does not detect an emergency. When in doubt, contact a doctor, and in an emergency use the emergency number. First aid is not a substitute for the emergency line. The rules your clinic and the emergency service explain apply.

What matters if you witnessed it

If you are the one who watched, you help most with a clear report. Note what you saw, when it began, and how long it lasted. Offer to write it down or to come to the appointment. On the support for family and friends page you can read how close people support without taking over.

Record the event in Sam and bring a report

You build a record you can hand to the doctor, instead of telling the story later from memory. Until your doctor confirms what it was, you keep the event in the symptom diary. If your doctor diagnoses epilepsy, the epilepsy program adds a diary with its own doctor report.

• Instead of a paper sheet: you record the day's symptoms in the symptom diary, and witnesses' observations stay on paper.
• Instead of memory: the monthly report as a PDF shows your symptom days and travels with you.

The program starts only after a doctor's diagnosis. Sam records; it is not medical advice and not an emergency line.
