Can prolonged seizures cause brain damage?
To summarize, prolonged seizures can result in brain damage, while recurring seizures can also have adverse effects on brain functioning. In turn, traumatic brain injuries can also lead to various types of seizures, which may cause further damage.
What is a status epilepticus?
Overview. Status epilepticus (SE) is a very severe type of seizure. For someone who has seizures, they’re normally similar in length each time they occur and typically stop once that time period has passed. SE is the name given to seizures that don’t stop, or when one seizure comes after another without the person having time to recover.

The person with epilepsy should write the care plan with their doctor or nurse. This lets them give their informed consent to emergency treatment.
What is the difference between a nonconvulsive and nonconvulsive SE?
For the new proposed definition of SE, time point t1 is five minutes, and time point t2 is 30 minutes. Nonconvulsive SE occurs when: a person has long or repeated absence or focal impaired awareness (also called complex partial) seizures. a person may be confused or unaware of what’s going on, but isn’t unconscious.
How long does a convulsive SE last?
Convulsive SE occurs when: the tonic-clonic seizure lasts five minutes or longer. a person goes into a second seizure before recovering from the first one. a person has repeated seizures for 30 minutes or longer. For the new proposed definition of SE, time point t1 is five minutes, and time point t2 is 30 minutes.
Why is it so hard to diagnose nonconvulsive SE?
It can be difficult to diagnose nonconvulsive SE because the condition may be mistaken for other conditions, such as psychosis and drug intoxication.
What happens after time point T2?
It is a condition, which can have long-term consequences (after time point t2), including neuronal death, neuronal injury, and alteration of neuronal networks , depending on the type and duration of seizures.”. Time point t1 is the point at which treatment should begin. Time point t2 is the point at which long-term consequences may develop.
When was SE given a new definition?
SE was given a new definition in 2015 as part of a revision of the classification of seizures. This is to help make diagnosing and managing seizures easier. Previous definitions didn’t provide specific time points for when to treat SE or when long-term side effects or complications were likely to begin.

Why does a patient stay awake during a seizure?
The patient remains awake and aware of the seizure activity because the reticular activating system and both cerebral hemispheres are not involved.
What is a sudden and temporary alteration in brain function caused by massive, continuing electrical discharges in a group?
Abnormal electrical discharges in the brain. A seizure is a sudden and temporary alteration in brain function caused by massive, continuing electrical discharges in a group of nerve cells in the brain.
How to tell if a seizure is syncope or seizure?
Seizures often get confused with syncope. The difference is that with syncope, the episode usually begins in a standing position, the patient remembers feeling faint or light-headed, the patient becomes responsive almost immediately after becoming supine, and the skin is usually pale and moist. The patient's statement that she woke up when she hit the floor is most consistent with syncope. If the patient has no idea how long she was unresponsive, was sitting when she became unresponsive, or had a strange taste perception before becoming unresponsive, these would all be less consistent with syncope and may be more indicative of seizure activity.
How long does a cyanotic seizure last?

What to do if a patient faints and is not responding appropriately upon arrival?
If the patient faints and is not responding appropriately upon your arrival, consider the condition an altered mental status. Perform primary and secondary assessments and manage the patient's airway, breathing, oxygenation, and circulation as you would for any patient with altered mental status.

How do benzodiazepines work?
Benzodiazepines work by binding to GABA (gamma-aminobutyric acid) receptors in the central nervous system, which in turn hyperpolarises the neuronal membrane making it more difficult for the neuron to be activated. 6 Midazolam and Diazepam are the benzodiazepines routinely used in the management of status epilepticus.
