Which EEG patterns in coma are nonconvulsive status epilepticus?

Non-convulsive status epilepticus status (NCSE) is common for coma patients with a prevalence of less than 5%

Patients with 48% deep coma may present epileptic EEG patterns such as common periodic spikes.

There was discussion on the relationship between these models and NCSE. The purpose of this review is

(I) discuss various EEG patterns seen in coma, their variations and transitions, (ii) suggest change

Classical coma aberration mode, diffusion polymorphism δ activity, spindle coma aberration, α / θ coma, low output

Voltage or pulse suppression does not affect NCSE. Arbitrary seizure pattern and typical space-time evolution

In comatose patients epileptic seizures exceed 5 Hz, reflecting non-convulsive attacks or NCSE

It should be treated. Generalized period secondary generalized or lateral periodic discharge (GPD / LPD)

A rhythm discharge (RD) with a frequency less than 5 Hz or faster than 0.5 Hz is the boundary of NCSE

Coma In such cases, at least one additional criterion is required to diagnose subtle clinical symptoms of NCSE (a).

Phenomenon, (b) typical spatiotemporal evolution, or (c) response to antiepileptic drug therapy. I'm waiting

There is currently no consensus on how long these models must exist to qualify for NCSE.

Non seizure seizures in patients with severe illness or coma are optional

The NCSE Salzburg consensus standard [1] has been modified according to standardized terminology.

The American Society of Clinical Neurophysiology [2] has been validated in three sensitive cohorts of high sensitivity.

95.2%, specificity 95.9%, diagnostic accuracy of patients with clinical symptoms of NCSE was 96.3%. That

EEG can also be used in intensive care units to monitor non-convulsive seizure / nonconvulsive status epileptic status and to monitor the effects of sedation / anesthesia on medically induced coma. In cases of subarachnoid hemorrhage, pressure of intracranial function is increased and secondary brain injury is monitored (currently a research method). If an epileptic patient is considering resection it is often necessary to find the focal point of epileptic brain activity (focus) at a higher resolution than the resolution provided by the scalp EEG. This is because the cerebrospinal fluid, skull and scalp are applied to the potential recorded by the scalp electroencephalogram. In these cases, the neurosurgeon usually embeds the strip and electrode grid (or penetrates the deep electrode) beneath the dura by craniotomy or perforation.

The electroencephalography records the activity of the brain using an electrode attached to the scalp (a small metallic disk with a wire). EEG does not detect viruses that cause encephalitis, but some patterns on the EEG may warn your neurologist the cause of your symptoms. Encephalitis can cause seizures and subsequent coma. This is why brain waves are important for determining the type of EEG generated in the diseased brain region and each region. Encephalitis is not necessarily preventable, but you can reduce the risk by vaccinating a virus that may cause encephalitis. Also check that your child has been vaccinated with these viruses. In areas with many mosquitoes and cockroaches, please use repellent, long sleeves, trousers. If you are visiting an area known for viruses that cause encephalitis, please check the vaccination advice on the Centers for Disease Control and Prevention (CDC).
