The Three Phases of Grand Mal Seizures
- The Preictal Phase (Prodrome Phase)
- The Tonic-Clonic Phase.
- Postictal Phase.
What are the three main phases of a seizure?
The four phases of seizure are:
- Prodromal
- Early ictal (the “aura”)
- Ictal
- Postictal
What are the early warning signs of approaching seizure?
- Unusual smells, tastes, sounds, or sensations
- Nausea
- A Déjà vu feeling (you feel like you are experiencing something that has occurred before)

What are the early signs of seizures?
These types of seizures produce many common seizure symptoms, such as:
- rapid eye movement
- loss of consciousness
- muscle spasms
- crying out
- falling to the ground
What happens before you have a seizure?
Yet, many people have no aura or warning; the seizure starts with a loss of consciousness or awareness. Common symptoms before a seizure: Awareness, Sensory, Emotional or Thought Changes: Déjà vu (a feeling that a person, place or thing is familiar, but you've never experienced it before)
What is the prodromal phase of a seizure?
The prodromal phase is a subjective feeling or sensation that can occur several hours or even days before the actual seizure. Prodromal is defined as the period from when early symptoms begin to before the more obvious, diagnosable symptoms begin.
What happens right before a seizure?
Seizure warning signs before the first 'full-blown' seizures These warning signs may include feeling “funny” or dizzy, or having jerking and twitching for several years. Other signs include fainting, headaches, vomiting, losing sensation in a certain parts of the body, daydreaming, and blackouts.
What are the 3 main types of seizures?
Tonic, Clonic and Tonic-Clonic (Formerly called Grand Mal) Seizures.
What are 3 signs of a seizure?
General symptoms or warning signs of a seizure can include:Staring.Jerking movements of the arms and legs.Stiffening of the body.Loss of consciousness.Breathing problems or stopping breathing.Loss of bowel or bladder control.Falling suddenly for no apparent reason, especially when associated with loss of consciousness.More items...
What would cause a seizure all of a sudden?
Seizures can happen for many reasons; It may be from high levels of salt or sugar in your blood; brain injury from a stroke or head injury brain problems you are born with or perhaps a brain tumor. Dementia, such as Alzheimer's disease, high fever or illnesses or infections that hurt your brain.

What is the most common type of seizure?
Generalized Seizures Generalized Tonic Clonic Seizures — Also known as a convulsion, this is the most common and easily recognized kind of generalized seizure.
What happens to the brain during a seizure?
In epilepsy the brain's electrical rhythms have a tendency to become imbalanced, resulting in recurrent seizures. In patients with seizures, the normal electrical pattern is disrupted by sudden and synchronized bursts of electrical energy that may briefly affect their consciousness, movements or sensations.
What happens during a seizure?
A seizure is a medical condition where you have a temporary, uncontrolled surge of electrical activity in your brain. When that happens, the affected brain cells uncontrollably fire signals to others around them. This out-of-control electrical activity overloads the affected areas of your brain.
How do you know if you are having a seizure?
Electroencephalogram (EEG) – Using electrodes attached to your head, your doctors can measure the electrical activity in your brain. This helps to look for patterns to determine if and when another seizure might occur, and it can also help them rule out other possibilities.
Does an EEG show past seizures?
The EEG generally records brain waves between seizures, called interictal brain waves. These waves may or may not show evidence of seizure activity.
What does a seizure feel like in your head?
You're not likely to lose consciousness, but you might feel sweaty or nauseated. Complex focal seizures: These usually happen in the part of your brain that controls emotion and memory. You may lose consciousness but still look like you're awake, or you may do things like gag, smack your lips, laugh, or cry.
How do you know if a seizure is coming on?
Aura (Late Warning Signs) A Déjà vu feeling (you feel like you are experiencing something that has occurred before) Intense fear and panic. 'Pins and needles' sensation in certain parts of your body. Jerky movements in of the arm, leg, or body.
How do you know if your having a seizure?
A staring spell. Uncontrollable jerking movements of the arms and legs. Loss of consciousness or awareness. Cognitive or emotional symptoms, such as fear, anxiety or deja vu.
Can you stop a seizure if you feel it coming?
Seizures can be unsettling, but many people find that they're able to control or stop them with medicine. Surgery,devices that stimulate nerves or detect seizures then stop them, and even diet changes are other ways to deal with them. Your doctor can work with you to find a treatment that helps.
Can you anticipate a seizure?
Some persons with epilepsy can self-predict seizures. In these individuals, the odds of a seizure following a positive prediction are quite high and are not attributable to remembering the seizure and are more associated to self-awareness.
What is the most prominent phase of a seizure?
Ictal Phase. The most prominent and visibly apparent phase of a seizure is described as the ictal phase. During this phase, you may experience alterations in consciousness, involuntary movements—or both. A seizure can be described as a convulsive seizure (with shaking or jerking movements) or a non-convulsive seizure ...
How does knowing the sequence of seizures help you?
Knowing the sequence of your seizure phases can help you manage your epilepsy and can help you assess how well your anti-epilepsy medication is working.
What is the term for a seizure that involves a rhythmic jerking of one part of the?
Myoclonic seizures: Sometimes these seizures occur in hereditary epilepsy, and they involve involuntary rhythmic jerking of one part of the body, typically with impairment of consciousness. Myoclonic epilepsy is a type of epilepsy with predominantly myoclonic seizures.
What is the postictal phase of epilepsy?
Postictal Phase. Seizure phases include the aural stage, the ictal stage, and the postictal stage. A seizure is a brief episode involving changes in consciousness and/or involuntary (not on purpose) shaking or jerking of the body. If you or your child has epilepsy, you may experience a seizure pattern that involves only ...
What is a seizure without movement?
A seizure can be described as a convulsive seizure (with shaking or jerking movements) or a non-convulsive seizure (without any unusual physical movements). Involuntary movements may involve your whole body, or one side of your face, arm, or leg. Typically, the muscle movements are rhythmic and repetitive.
What is the aura of a seizure?
An aura is caused by an alteration in brain activity that begins shortly before the most noticeable part of the seizure, which is the ictal stage. 1
How long does an aura last?
This stage occurs immediately before the ictal stage of a seizure and it can last from a few seconds to an hour in duration. Most people are aware of their own symptoms during a seizure aura. You may or may not have an aura prior to your seizures.
Focal onset seizures
The first main type of seizures—focal seizures — begin on one side of the brain, in one particular area, according to the Epilepsy Foundation. " Focal means there's a focus, a spot from which everything emanates," Vikram Rao, MD, PhD, an associate professor of neurology at the University of California, San Francisco, tells Health .
Generalized onset seizures
Generalized onset seizures are seizures that affect both sides of the brain (or cells in both sides of the brain) at once, according to the Epilepsy Foundation. "That means that there is no epicenter," Dr. Rao says. "We think of that as kind of a network-level imbalance, where the seizure actually starts everywhere simultaneously."
Unknown onset seizures
Sometimes, doctors don't know where a particular seizure began in the brain. In those cases, it's called an unknown onset seizure, the Epilepsy Foundation says. Unknown onset seizures can also be classified as such if they're not witnessed or seen by anyone else, say, if they happen at night or if the person experiencing the seizures lives alone.
Non-epileptic seizures
Something important to know about seizures in general: They aren't all related to epilepsy. Sometimes, a person without epilepsy can experience a seizure. However, the NINDS insists that regardless of what causes a seizure, or the type of seizure, all seizures should be checked out by a doctor.
Why do the types of seizures matter?
The reason it's so important for a doctor to determine the type of seizure a patient has—and specifically where in the brain his or her seizures are beginning—is because that information will help determine the person's treatment plan.
