Lennox's syndrome

Overview also known as Lennox-Gastaut syndrome, Blink-nod-fall case, myoclonic seizures rose to no other. Cause pathogenesis is still unclear. Idiopathic who accounted for 10 ~ 30%. Diseases based mental retardation make up the majority, followed by cerebral palsy, brain injury sequels, sequels, such as encephalitis, The disease may be obstacles for the development of brain damage with some organic diseases. Clinical features of special clinical seizures and diffuse EEG, rules of spikes syndrome. Past history of a number of different types of epilepsy, mainly for ankylosing spasm or (and) not typical absence seizure. Ankylosing seizures head flexion, shoulder-held, forearm outreach, ankylosing spasm without limbs fall may have temporary disturbance of consciousness, rapid recovery, attack the entire process from a few seconds to 30 seconds, with faster connections, elevated blood pressure and other autonomic symptoms, not with the typical absence seizure, and other attacks. The atypical absence seizures are characterized by paroxysmal disturbance of consciousness, we can see eye to transfer, Seizure frequency from once a month to daily dozens of daily attacks over 10 accounted for about 50 All patients have different levels of mental disability, age increased Shifter small attacks and acts of absence seizures. All cases can be seen intermittent attacks EEG characteristics of the diffuse Spikes integrated, particularly vulnerable in the shallow sleep period. Differential diagnosis (1) Mental retardation pronunciation (oligophrenia) is caused by various reasons, the smart fat Yuk retardation as the main characteristics of a group of diseases. In addition to mental retardation, the entire spirit of the development activities than normal backward. Should be possible to identify the causes of the three-year-old child diagnosed with the disease should have a cautious attitude. (2) cerebral palsy (defined as cerebral) includes a variety of diseases caused by the brain since birth net deposit in the bilateral muscle tension and functional change is caused by many reasons for the non-progressive brain damage syndrome. Mainly for movement disorders, mental retardation and epilepsy, etc.. Most cases in a few months after the family as they tried to Lifting unusual. (3) should pay attention to the disease and other types of identification of an epilepsy. Infantile Spasms (infantile spasm ) : all in a year after the birth of incidence. Most of the symptoms, before showing the incidence of stunting and neurological symptoms, idiopathic ill nothing abnormal, performance for a short ankylosing cramps, a flexor more notable. EEG significantly high potential diffuse slow irregular activities, miscellaneous have spikes and sharp wave, when there is short spasm of low potential. Attack in 2 ~ 5-year-old vanished, but more than half into atypical absence seizures, such as ankylosing attack. 2. Serious baby myoclonic epilepsy (Infantile myeelonic epilepsy) : incidence in a year after birth. Since fever when clonic seizures, myoclonic began, growth retardation, pyramidal signs and ataxia. EEG Spikes said extensive, multi - spike-wave, as well as flash twitch response.
