Seizure types vary by where they begin in the brain and how far they spread. Most seizures last from 30 seconds to two minutes. A seizure that lasts longer than five minutes is a medical emergency. Seizures can happen after a stroke or a head injury.
A seizure that lasts for more than a brief period is a medical emergency. Any seizure lasting longer than five minutes should be treated as status epilepticus. A first seizure generally does not require long-term treatment with anti-seizure medications unless a specific problem is found on electroencephalogram (EEG) or brain imaging.
Mar 17, 2023 · Viewing brain waves during a seizure can help your doctor diagnose the type of seizure. An EEG can show evidence of seizure activity even when a person isn’t having a seizure.
Dec 9, 2021 · A seizure is an abnormal electrical discharge of a group of brain cells. It can cause different symptoms, depending on the location of the seizure and the spread of electrical activity through the brain.
Seizures are due to sudden, temporary, abnormal electrical signals firing in the brain. Seizures lead to changes in behaviours, movement, level or awareness and feelings. Epilepsy occurs when you have recurrent seizures. For most people, medicines are effective in managing seizures.
Seizure types depend partly on where they happen in your brain. A healthcare provider can determine where they happened based on your symptoms. Seizure location tends to happen in two main ways: Generalized seizures: These are seizures that happen in both sides (hemispheres) of your brain side.
Oct 14, 2023 · Epilepsy happens as a result of abnormal electrical brain activity, also known as a seizure, kind of like an electrical storm inside your head. And because your brain controls so much, a lot of different things can go wrong.

Not everyone who has a seizure has epilepsy. Learn about provoked seizures, nonepileptic events due to other issues and psychogenic nonepileptic seizures. Seizures involve sudden, temporary, bursts of electrical activity in the brain that change or disrupt the way messages are sent between brain cells.
Dec 4, 2023 · What Is a Seizure? A seizure is abnormal electrical activity in the brain that happens quickly. It may go nearly unnoticed.
A seizure is a burst of uncontrolled electrical activity between brain cells that causes temporary abnormalities in muscle tone or movements (stiffness, twitching or limpness), behaviors, sensations or states of awareness.
Seizures can take on many different forms, and seizures affect different people in different ways. Anything that the brain does normally can also occur during a seizure when the brain is activated by seizure discharges. Some people call this activity “electrical storms” in the brain. Seizures have a beginning, middle, and end.
The onset or beginning of a seizure: Where seizures start in the brain tells a lot about what may occur during a seizure, what other conditions or symptoms may be seen, how they may affect someone and, most importantly, what treatment may be best for that seizure type.
Feb 7, 2024 · Around 50 million people worldwide have epilepsy, making it one of the most common neurological diseases globally. Nearly 80% of people with epilepsy live in low- and middle-income countries. It is estimated that up to 70% of people living with epilepsy could live seizure-free if properly diagnosed and treated.
Symptoms. Overview. Symptoms. Diagnosis. Treatment. Living with. The main symptom of epilepsy is repeated seizures. These are sudden bursts of electrical activity in the brain that temporarily affect how it works. Seizures can affect people in different ways, depending on which part of the brain is involved.
A seizure is a sudden and temporary change in the electrical and chemical activity in the brain which leads to a change a person’s movement, behaviour, level of awareness, and/or feelings. Some people will experience a seizure, but will not go on to be diagnosed with epilepsy, whereas others will.
