Hope  for  ULD

What is ULD?

PLEASE NOTE: If you or a family member are interested in possible participation in research aimed at developing therapies for Unverricht-Lundborg Disease (EPM1), please fill out this form located on our site.

Unverricht-Lundborg Disease (ULD) is a rare Progressive Myoclonic Epilepsy, also known as EPM1. It is a neurodegenerative condition, which becomes increasingly debilitating over time.


ULD is an autosomal recessive disease caused by mutations in the gene, cystatin B (CSTB). In order to have the disease, a person must have two mutated copies (alleles) of the CSTB gene. A person with one normal copy of CSTB (dominant) and one mutated copy (recessive) is a carrier, but that person does not have the disease.


ULD progresses slowly, but tends to be debilitating as it progresses. Many ULD patients experience years of myoclonic and tonic clonic seizures. Patients have stimulus-sensitive seizures. Myoclonus events can be both positive myoclonus (abrupt muscle contractions) and negative myoclonus (sudden interruption of muscular activity). 


As the disease progresses, patients commonly begin to experience ataxia and more negative myoclonus, resulting in many falls and injuries. They often also experience trouble speaking, emotional lability, and depression. Patients can endure much emotional and physical pain. Severe depression and psychiatric problems can be present. Many patients end up in wheelchairs, and often need help with daily living activities, such as eating and bathing. ULD patients have stimulus sensitive myoclonic jerks that are more frequent and severe when they try to move, think, or process any changes in their environment, such as light or movement. The severity can differ from patient to patient.
