If an individual with Unverricht–Lundborg disease is particularly sensitive to a certain type of stimulus, it is also beneficial to reduce the patients exposure to that stimulus in order to reduce the likelihood of seizures. Since ULD is progressive and may not get better over time, depression has been documented in many cases, so providing a strong support group of friends, family, and even other individuals with ULD is very beneficial. Prognosis
For early Unverricht–Lundborg disease patients, the disease would begin to progress early and lack of effective treatment meant a quick progression. In many cases the patient would require a wheelchair for mobility, and would die at a young age.However, increased knowledge about the disease and improved treatment and medication has led to a dramatic improvement in prognosis for individuals with ULD. Antiepileptic drugs reduce the occurrence of seizures and myoclonus, which leads to a decrease in the damage caused in the brain due to seizures and the body due to falls resulting from the seizures. As a result, individuals with Unverricht–Lundborg disease are now much less likely to end up in a wheelchair, which eliminates the chance of complications involved with being a wheelchair user. All these factors have increased the outlook for patients. Due to the progressive nature of the disease, depression is prevalent, but support of family and friends as well as proper treatment can help. While early patients with ULD had a life expectancy of around 24 years, there have recently been reported cases of individuals living to near-normal ages.
Unverricht–Lundborg disease (abbreviated ULD or EPM1) is the most common form of an uncommon group of genetic epilepsy disorders called the progressive myoclonus epilepsies. It is caused due to a mutation in the cystatin B gene (CSTB). The disease is named after Heinrich Unverricht, who first described it in 1891, and Herman Bernhard Lundborg, who researched it in greater detail in 1901 and 1903. ULD onsets in children between the ages of 6 and 16; there are no known cases in which the person was older than 18. Most cases originate from the Baltic region of Europe, though many have been reported from countries in the Mediterranean.Onset of the disease is characterized by myoclonic jerks and tonic-clonic seizures. Early cases often resulted in the need of a wheelchair and death before the age of 24, but new treatments and medications have increased the life expectancy of individuals with ULD, in some cases even to near that of an unaffected individual. Signs and symptoms
Patients with Unverricht–Lundborg disease exhibit myoclonic jerks and tonic-clonic seizures at a young age, between ages 6–16. The myoclonic jerks occur in the muscles of the arms and legs closest to the torso, and are triggered due to a variety of common external stimuli. Seizures begin at an average age of 10.8 years, with myoclonus beginning around 12.1 years. It is not currently possible to diagnose without a genetic test, and since early symptoms are general, it is often mistaken for another more common epilepsy, in many cases juvenile myoclonic epilepsy (JME).
