Seizure-induced aphasia syndrome in children
Introduction
Introduction to pediatric seizure-induced aphasia syndrome The seizure-induced aphasia syndrome, Landau-Kleffner syndrome, is caused by seizures that cause linguistic dysfunction in the language center. basic knowledge The proportion of illness: 0.001% Susceptible people: children Mode of infection: non-infectious Complications: disturbance of consciousness
Cause
Pediatric seizures induce the cause of aphasia syndrome
(1) Causes of the disease
This symptom is an aphasia that occurs on the basis of seizures.
(two) pathogenesis
Regarding the mechanism of aphasia, it may be that the epileptic discharge leads to the dislocation of the original language region of the brain. After treatment, the aphasia can be gradually improved, indicating that the seizure activity is not caused by the destruction of the language center structure, but the dysfunction of the language center.
Prevention
Pediatric seizure induced aphasia syndrome prevention
Prevent epilepsy and effectively control the onset of epilepsy.
1. Prevention of epilepsy
The etiology and pathogenesis of epilepsy are complicated, and prevention is difficult. At the same time, about 70% of the current epilepsy patients have unknown causes, which prevents prevention, and a considerable part of symptomatic epilepsy, although the cause is clear, prevention is difficult, such as the brain. Tumors, arteriovenous malformations, etc., and seizures are the result of a combination of multiple factors, including at least the threshold of convulsions (related to genetic factors), neurological disorders and predisposing factors, which also increase the difficulty of prevention, but this does not mean Incapable of preventing epilepsy, from the perspective of etiology, some such as improper care during the birth period, intracranial infections, infectious diseases of newborns and young children, dehydration of infants, uncontrolled febrile seizures and head trauma Epilepsy can rely on corresponding measures to prevent its occurrence. Timely and reasonable treatment of patients with epilepsy can prevent intractable epilepsy and a series of physical and psychosocial disorders. It is also important for patients, and some epilepsy with obvious predisposing factors Prevent epilepsy by carefully searching for and avoiding predisposing factors, ie epilepsy For prevention.
2. Non-specific predisposing factors
Such predisposing factors generally act by lowering the threshold of epilepsy, so it can not only induce epilepsy in epileptic patients but also lead to state-related seizures, and if the effect exceeds a certain limit, it may also cause seizures in normal people, such as Sleep deprivation, fatigue, hunger, dehydration or excessive drinking, drinking, cold, fever, mental stimulation, various metabolic disorders, etc., a patient may be sensitive to a certain factor, so you should carefully ask about the triggering factors, pay attention in life Avoid, but indeed some predisposing factors are unavoidable, such as sleep induction, induction of menstrual cycle.
Doctors should guide patients to establish good living habits, avoid excessive fatigue, lack of sleep, encourage normal learning, avoid bad habits such as tobacco and alcohol, drugs, and often see many children with epilepsy during normal schooling. Epilepsy can be well controlled, but due to the destruction of life rules and excessive play, especially when watching TV for a long time, playing games, etc., the seizures increase significantly, so if the child has an unexplained seizure, pay attention to this. Aspects of the situation.
3. Special predisposing factors
In some patients with special epilepsy, the seizure may be induced by environmental or intrinsic predisposing factors, and this predisposing factor is not directly related to epilepsy in nature, and does not cause seizures in normal people, such as a piece of music, mental arithmetic, etc. If the predisposing factor is sensory or perceptual, then the epilepsy is called reflex epilepsy. The special predisposing factors are closely related to seizures in time, and then there is an episode immediately after the stimulation.
The number of patients with epilepsy induced by special factors is small, but there are many types. The induced seizures can be generalized or partial, and advanced brain function exercise patterns are mostly complex partial seizures. Epilepsy can be For idiopathic, such as idiopathic reading epilepsy; can also be symptomatic, such as convulsive (sudden startle stimuli) epilepsy is mostly symptomatic, such patients due to the special mode of induction, a patient is only for a particular The evoked mode responds, so if you ask the medical history carefully, it is not difficult to find out, and avoiding the corresponding stimuli can prevent the seizure.
Complication
Pediatric seizures induce complications of aphasia syndrome Complications
Can be associated with cognitive, behavioral and emotional barriers.
Symptom
Pediatric seizures induce symptoms of aphasia syndrome common symptoms autonomic seizures of cognitive dysfunction epilepsy
The clinical manifestations of this symptom are as follows.
1. Epilepsy is the first symptom and main manifestation, and the form of seizure can be various, and some can be mixed.
2. The age of acquired aphasia is more than 3 to 9 years old. The language development of children before the onset is normal. Acquired aphasia occurs with seizures. The type is exercise, sensory or mixed, severity and epilepsy. The seizure is related to the epileptic discharge of EEG.
3. Psychiatric symptoms Some children may be associated with cognitive, behavioral and emotional disorders.
4. The EEG characteristics show a typical epileptic discharge.
Clinically, after one or more epileptic seizures, when the consciousness is clear, but can not speak, but the hearing is normal, can be nodded, eyes and body language, after about 2 to 3 days, the language can gradually recover, but often does not reach The original level, with the increase in the number of episodes, language barriers gradually worsened, if timely appropriate treatment, seizure control, language function can gradually recover.
Examine
Examination of pediatric seizure-induced aphasia syndrome
There are no specific findings in general laboratory tests.
The electroencephalogram can be expressed as paroxysmal spikes, bilaterally symmetrically synchronized high-amplitude Q waves, and spine-wave synthesis.
Diagnosis
Diagnosis and diagnosis of pediatric seizure-induced aphasia syndrome
According to the clinical manifestations, combined with EEG abnormalities can be diagnosed.
Early identification with rickets.
