What Is a Gelastic Seizure?

Cryptogenic epilepsy refers to the clinical manifestations of symptomatic epilepsy, but no clear cause can be found. Most of the patients with cryptogenic epilepsy are children. They start at a specific age and have no special clinical and EEG features . It is speculated that the child's nervous system is diseased, but the current cause, including imaging studies of various brains, has not been found for the time being.

Cryptogenic epilepsy

Cryptogenic epilepsy classification

1. Infantile spasms (West syndrome).

West syndrome usually consists of characteristic triads: infantile spasms, stagnant psychomotor development, and high rhythm disorders, in three ways. Lightning appeared in clusters. The age of onset is 4-7 months, usually before 1 year. Boys are more common and the prognosis is usually poor.

West syndrome can be divided into two categories: the symptomatic group is a person with previous brain damage, or has a well-defined cause: the idiopathic group is less common, characterized by no previous brain damage, and no clear cause. The poor prognosis depends in part on early ACTH or oral steroid treatment, but mainly depends on symptomatic or idiopathic, the latter has a better prognosis than the former.

2. Lennox-Gastaut syndrome.

The disease is more common in children 1-8 years old, mainly in preschool children. There are various forms of seizures. The most common forms of seizures are axial tonicity, loss of tension, and absence of seizures, but myoclonic, systemic tonic, or partial seizures are also common. Seizures are very frequent and a common state of epilepsy. EEG shows abnormal background activity, slow spines and slow complex waves, and often multifocal abnormalities. A rapid rhythm burst occurs during sleep. Generally, there is mental retardation, attacks are difficult to control, and the prognosis is poor. 60% of the cases occurred in those with previous encephalopathy, and the other cases were primary.

3, epilepsy with myoclonus and standing can not occur.

The disease begins at 6 months. Except for those affected within one year, boys are twice as likely as girls. There are often genetic factors and development is usually normal. Seizures often occur as clonic, erectile inability, myoclonic erectile inability, absence of clonic and tonic components, and tonic clonic seizures. The mental development was normal before the onset, and there was mental decline after the onset. Tonic seizures are seen in the late stages of poor prognosis. In the early stage of the EEG, except for the 4-7Hz rhythm, it is usually normal. In the future, there may be irregular fast-spike slow waves, or multi-spike slow complex waves. In the state of epilepsy, there are irregular 2-3Hz slow-spike complex waves. The course and prognosis are uncertain.

4. Epilepsy with myoclonic absence.

This disease is characterized by absence of vision accompanied by severe bilateral rhythmic clonic beats, often accompanied by tonic contraction. The EEG showed bilateral synchronous and symmetrical 3Hz spiky slow complex waves, similar to children's loss of mind. A few times a day, consciousness can be saved. Rarely accompanied by other attacks. Onset is about 7 years old, more common in boys. Due to poor treatment effect, and there is mental retardation and may progress to other types, the prognosis of denser epilepsy is poor.

Cryptogenic epilepsy early symptoms of epilepsy

Although epileptic seizures are relatively sudden, they can be found in the first place through early symptoms, and then treated and controlled for seizures. Some patients become irritable, have a bad mood, and are easily agitated at an early stage. In addition, patients will have some visual and auditory symptoms. What are the early symptoms of epilepsy? ^[1]

(1) Early symptoms generally include symptoms of irritability, irritability, depression, moodiness, often picky or complaining about others.

(2) Early symptoms of epilepsy include the following signs:

Somatosensory aura. These include tingling, numbness, and loss of sensation.

Visual aura. This includes seeing moving or stationary light spots, apertures, Mars, black spots, a mass of monochromatic or colored objects, etc.

auditory aura. Including hearing bells, bird calls, insect calls, machine sounds, etc.

Aura of smell. Including pungent odors such as burnt rubber, fishy, and sulfuric acid.

Aura of taste. Including unpleasant tastes such as bitter, sour, salty, sweet, and greasy in the mouth.

emotional precursors. Including anxiety, restlessness, depression, panic, etc., fear is the most common type.

Spiritual precursors. This includes illusions, hallucinations, things that are seen or felt that do not actually exist, etc. In addition, there are dizziness, abdominal discomfort, and head discomfort.

Cryptogenic epilepsy treatment

Cryptogenic epilepsy drug

Drug treatment is generally the first treatment method, and different drugs are selected according to the clinical manifestations of each person.

Cryptogenic epilepsy surgery

When the drug can not be controlled ideally, surgery can be selected. The surgical methods are 1. cerebral cortex resection; 2. hemi-cerebral resection; 3. temporal lobe resection; Laser destruction.
