Overview

Unverricht-Lundborg disease is an inherited form of progressive myoclonus epilepsy that is characterized by episodes of involuntary muscle jerking or twitching (myoclonus) that increase in frequency and severity over time. Episodes of myoclonus may be brought on by physical exertion, stress, light, or other stimuli. Affected individuals usually begin showing signs and symptoms of the disorder between the ages of 6 and 15. Over time, the myoclonic episodes may become severe enough to interfere with walking and other everyday activities. Other features include seizures involving loss of consciousness, muscle rigidity, and convulsions (tonic-clonic or grand mal seizures). Like the myoclonic episodes, these may increase in frequency over several years but may be controlled with treatment. After several years of progression, the frequency of seizures may stabilize or decrease. Unverricht-Lundborg disease is caused by mutation in the CSTB gene. It is inherited in an autosomal recessive pattern.[1]
