Status epilepticus (SE), or status seizure, is a medical condition consisting of a single seizure lasting more than 5 minutes, or 2 or more seizures within a 5-minute period without the person returning to normal between them. [3][1] Previous definitions used a 30-minute time limit. [2] The seizures can be of the tonic–clonic type, with a ...
Absence seizures affect between 0.7 and 4.6 per 100,000 in the general population and 6 to 8 per 100,000 in children younger than 15 years. Childhood absence seizures account for 10% to 17% of all absence seizures. Onset is between 4 and 10 years and peaks at 5 to 7 years. It is more common in girls than in boys. [7]
A seizure is a period of symptoms due to abnormally excessive or synchronous neuronal activity in the brain. [6] Outward effects vary from uncontrolled shaking movements involving much of the body with loss of consciousness (tonic-clonic seizure), to shaking movements involving only part of the body with variable levels of consciousness (focal seizure), to a subtle momentary loss of awareness ...
Postictal state. The postictal state is the altered state of consciousness after an epileptic seizure. It usually lasts between 5 and 30 minutes, but sometimes longer in the case of larger or more severe seizures, and is characterized by drowsiness, confusion, nausea, hypertension, headache or migraine, and other disorienting symptoms.
Status epilepticus is a seizure "lasting longer than 30 minutes or a series of seizures without return to the baseline level of alertness between seizures." [ 12 ] Epilepsia partialis continua is a rare type of focal motor seizure, commonly involving the hands or face , which recurs with intervals of seconds or minutes, lasting for extended ...
Spike-and-wave is a pattern of the electroencephalogram (EEG) typically observed during epileptic seizures. A spike-and-wave discharge is a regular, symmetrical, generalized EEG pattern seen particularly during absence epilepsy, also known as ‘petit mal’ epilepsy. [1] The basic mechanisms underlying these patterns are complex and involve ...
Focal seizures (also called partial seizures[1] and localized seizures) are seizures that affect initially only one hemisphere of the brain. [2][3] The brain is divided into two hemispheres, each consisting of four lobes – the frontal, temporal, parietal and occipital lobes. A focal seizure is generated in and affects just one part of the ...
Childhood absence epilepsy (CAE), formerly known as pyknolepsy, is an idiopathic generalized epilepsy which occurs in otherwise normal children. The age of onset is between 4–10 years with peak age between 5–7 years. Children have absence seizures which although brief (~4–20 seconds), they occur frequently, sometimes in the hundreds per day.
