A seizure is a sudden change in behavior, movement or consciousness due to abnormal electrical activity in the brain. [3] [6] Seizures can look different in different people.. It can be uncontrolled shaking of the whole body (tonic-clonic seizures) or a person spacing out for a few seconds (absence seizure
Because epileptic seizures typically include convulsions, the term convulsion is often used as a synonym for seizure. [1] However, not all epileptic seizures result in convulsions, and not all convulsions are caused by epileptic seizures. [1] [2] Non-epileptic convulsions have no relation with epilepsy, and are caused by non-epileptic seizures. [1]
During the typical 1 minute seizure, a person experiences a familiar (déjà vu) sensation, followed by picking and fumbling hand movements. After this seizure, the person cannot recall what was said during the seizure. Brain magnetic resonance imaging (MRI) shows left hippocampal sclerosis, a brain abnormality associated with focal seizures. [11]
Local epilepsy advocates have developed emergency medical cards with a step-by-step guide for people who encounter someone experiencing a seizure. People with epilepsy can get seizures at any time ...
Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. [10] An epileptic seizure is the clinical manifestation of an abnormal, excessive, and synchronized electrical discharge in the neurons. [1]
The prevalence of this disorder is approximately 1/16,00 live births. [8] Seizures begin before 20 months of age and in most cases, the first seizures occur with fever and are generalized tonic-clonic (grand mal) or unilateral (one-sided) convulsions. These seizures are often prolonged, and may lead to status epilepticus, a medical emergency.
Between 10% and 30% of people who have status epilepticus die within 30 days. [1] The underlying cause, the person's age, and the length of the seizure are important factors in the outcome. [2] Status epilepticus occurs in up to 40 per 100,000 people per year. [2] Those with status epilepticus make up about 1% of people who visit the emergency ...
Stress can induce seizures in people with epilepsy, and is a risk factor for developing epilepsy. Severity, duration, and time at which stress occurs during development all contribute to frequency and susceptibility to developing epilepsy. It is one of the most frequently self-reported triggers in patients with epilepsy. [48] [49]
