Topic: Juvenile myoclonic epilepsy


  
  International League Against Epilepsy
Myoclonic seizures occur in patients with other idiopathic generalized epilepsies such as the absence epilepsies, and epilepsy with grand mal seizures on awakening, but are not the most prominent features of these syndromes.
In the latter two, the myoclonic seizures usually involve the face and are associated with absences, whereas consciousness is not impaired during the myoclonic seizures of juvenile myoclonic epilepsy.
Proposal for revised classification of epilepsies and epileptic syndromes.

She never had myoclonic or generalized tonic-clonic seizures, and her seizures were well controlled with a drug that was considered ineffective in the treatment of these other types of seizures.
Myoclonic jerks, GTCSs, and absence seizures all have an age-related onset in JME.
This occurs in approximately 30% of patients with JME, compared with 18% of patients with childhood absence epilepsy, 13% of patients with epileptic seizures on awakening, and 7.5% of patients with juvenile absence epilepsy.

 Juvenile absence epilepsy
Juvenile absence epilepsy is an idiopathic epilepsy, and approximately 11% of patients reveal a family history of epilepsy (Wolf 1992).
The fundamental mechanisms of juvenile absence epilepsy are unknown; however, animal models of absence seizures suggest that rhythmic thalamic projections to diffusely epileptogenic cortex produce the characteristic hypersynchronous discharges and that enhanced inhibitory, as well as excitatory, mechanisms are involved (Gloor and Fariello 1988).
In epilepsy with grand mal seizures on awaking generalized convulsions are the presenting feature of the disorder, whereas in juvenile myoclonic epilepsy, bilateral myoclonic seizures are the most prominent symptom.

Several characteristics should raise the physician's index of suspicion for juvenile myoclonic epilepsy, including generalized tonic-clonic seizures that occur in the early morning, seizures that are pooly controlled in patients taking carbamazepine and infrequent seizures associated with alcohol use or sleep deprivation.

The idiopathic generalized epilepsies are genetically linked primary generalized seizure syndromes and include absence, juvenile myoclonic, and tonic-clonic on awakening.
The idiopathic generalized epilepsies -- absence, juvenile myoclonic (JME), and generalized tonic-clonic on awakening (Figure 1) -- are a heterogeneous group of disorders that usually respond well to pharmacotherapy.
Although valproate, the first-line treatment for idiopathic generalized epilepsies, is effective for most patients, pharmacoresistance will occur for some and the risk of weight gain and reproductive problems (teratogenicity, polycystic ovaries) makes the drug an unacceptable choice for others, particularly women in their childbearing years.

This is a fairly common type of epilepsy which can develop between eight and 26 years of age, but usually starts between 12 and 16.
As seizures are more likely to happen if a person does not get enough sleep or drinks alcohol, it is advisable for people with this syndrome to maintain regular sleeping habits and think carefully about the amount of alcohol they consume.

 juvenile myoclonic epilepsy
Juvenile myoclonic epilepsy is now known to be an inherited form of epilepsy, which in many (but not all) cases localizes to the 6th human chromosome.
The disorder typically begins in the teenage years and incorporates myoclonic seizures, which are irregular solitary or multiple jerks, especially when awakening, generallized tonic-clonic seizures (so called "grand mal" seizures), and sometimes atypical absence seizures.
Anyone old enough to get JME need not be concerned--- if your liver enzyme count was to rise, a brief reduction in the dose or level of the medication would almost assuredly fix the problem.

Juvenile myoclonic epilepsy (JME) is a non-progressive epilepsy characterized by involuntary jerks and an adolescent age of onset.
Relatives of the proband were classified as affected if they had a confirmed history of JME, absence or grand mal epilepsy, or if they were clinically asymptomatic but had 3.5-6 Hz multispike wave complexes on electroencephalography.
These results, along with contradictory reports regarding the linkage of JME to the short arm of chromosome 6, suggest the presence of genetic heterogeneity and/or a more complex mode of inheritance, such as a two-locus model.
