Partial Onset Seizure: What You Need to Know
Have you ever seen someone zoning out, twitching in one hand, or suddenly smelling things that aren’t there? Those can be signs of a partial onset seizure. Also called focal seizures, they start in one part of the brain and can look very different depending on where they begin. This short guide helps you spot them, respond safely, and understand common treatment paths.
How to recognize a partial onset seizure
Partial onset seizures can be simple or complex. Simple focal seizures don’t affect awareness — the person stays alert but may feel odd sensations, sudden jerks, or a strange taste or smell. Complex focal seizures do affect awareness: the person may stare blankly, move their lips, fiddle with clothes, or act confused for a minute or two. Afterward they can feel tired or disoriented.
Timing matters. These events often last seconds to a couple of minutes. If a seizure lasts more than five minutes, treat it as an emergency and call for help. If you’re unsure, note how long it lasted, what the person did, and whether they had a known seizure history — that info helps clinicians later.
Treatment and long-term care
Most people with partial onset seizures take antiseizure medicines (also called antiepileptic drugs). Common choices include lamotrigine, carbamazepine, levetiracetam, and others. Which drug fits best depends on the seizure type, side effects, other health issues, and sometimes blood tests. If meds don’t control seizures, doctors may suggest further testing — like longer EEG monitoring or an MRI — to find a clear source in the brain.
When medication isn’t enough, options include surgery to remove a small brain area causing seizures, vagus nerve stimulation (VNS), or a responsive neurostimulation device. Some people try diet changes (for example, a ketogenic diet) under close medical supervision. Any change should be discussed with a neurologist or epilepsy specialist, not tried alone.
Everyday steps help too. Keep a seizure diary with date, time, triggers, and how long events last. Avoid known triggers like poor sleep, heavy alcohol use, or missed meds. Wear medical ID if seizures could endanger you in daily life. For parents and caregivers, teach simple first aid: stay calm, protect the person from injury, time the seizure, and roll them onto their side if possible once convulsions stop. Don’t force anything into their mouth.
If you suspect new seizures, see a doctor fast. Early testing can speed up treatment and improve safety. Living with partial onset seizures often means small changes — better sleep, consistent meds, and a plan for emergencies — that add up to more control and confidence.
