Unverricht-Lundborg disease is a rare inherited form of epilepsy. Affected individuals usually begin showing signs and symptoms of the disorder between the. Unverricht-Lundborg disease (EPM1; OMIM ) is the most common of the rare genetically heterogeneous progressive myoclonic. Unverricht-Lundborg disease (ULD), progressive myoclonic epilepsy type 1 ( EPM1, OMIM), is an autosomal recessively inherited.

While early patients with ULD had a life expectancy of around 24 years, [8] there have recently been reported cases of individuals living to near-normal ages.

Progressive myoclonic epilepsies generally constitute only a small percentage of epilepsy cases seen, and ULD is the most common form.

Many studies have been performed recently to investigate the cause, mechanism, and chemical basis of Unverricht—Lundborg disease.

The natural history of Unverricht-Lundborg disease: However, genetic tests of this lunbdorg are prohibitively expensive to perform, especially due to the rarity of ULD.

Epilepsy and driving Epilepsy and employment. A recent study has attempted to characterize the effects, if any, seen in mice that carry only one recessive CSTB gene are heterozygous.

The study found that heterozygous mice performed similar to normal mice when the task was started, but as the task continued or became more complex they were more likely to fail. Summary and related texts. From Wikipedia, the free encyclopedia.

If an individual with Unverricht—Lundborg disease is particularly sensitive to a certain type of stimulus, it is also beneficial to reduce the patient’s exposure to that stimulus in order to reduce the likelihood of seizures.

Health care resources for this disease Expert centres Diagnostic tests 45 Patient organisations 48 Orphan drug s 2. However, with recent research linking ULD brain damage to the hippocampus, [11] the usefulness of EEG as a diagnostic tool may increase.

Unverricht–Lundborg disease

While the results for the heterozygous mice were not remarkably different from the normal mice, they do indicate that carrying just one recessive CSTB gene may have adverse effects, at least in mice. Views Read Edit View history.

For early Unverricht—Lundborg disease patients, the disease would begin to progress early and lack of effective treatment meant a quick progression. Seizures Simple partial Complex partial Gelastic seizure Epilepsy Temporal lobe epilepsy Frontal lobe epilepsy Lundobrg epilepsy Nocturnal epilepsy Panayiotopoulos syndrome.

Normally, after a seizure, the presence of cystatin B prevents the neurons from dying due to toxic levels of neurotransmitters. Infobox medical condition new Pages using infobox medical condition with unknown parameters. Only comments written in English can be processed. The researchers suggest that this clotting action of the cystatin B molecules may be one of the factors that cause progression of ULD.

Unverricht–Lundborg disease – Wikipedia

Specialised Social Services Eurordis directory. Unverricht—Lundborg disease abbreviated ULD or EPM1 is the most common form of an uncommon group of genetic epilepsy disorders called the ve myoclonus epilepsies. The documents contained in this web site are presented for information purposes only.


While there is no current cure to repair the mutated CSTB gene, several antiepileptic drugs are effective in reducing seizures and helping patients with ULD to manage the symptoms.

It is hypothesized that this increase in excitability is what causes the myoclonic jerks and tonic-clonic seizures in patients with ULD. Research also gives evidence to support the idea that cystatin B may be a type of “protecting” molecule in the brain.

The only currently available method to diagnose Unverricht—Lundborg disease is a genetic test to check for the presence of the mutated cystatin B enfrmedad. Febrile seizure Psychogenic non-epileptic seizures.

Current research has provided promising results that may lead to a confirmation of the mechanism. However, increased knowledge about the disease and improved treatment and medication has led to a dramatic improvement enfegmedad prognosis for individuals with ULD. Unverricht-Lundborg disease ULD is a rare progressive myoclonic epilepsy disorder characterized by action- and stimulus-sensitive myoclonus, and tonic-clonic seizures with ataxia, but with only a mild cognitive decline over time.
