Disease or Syndrome
A tremor-like cortical myoclonus. The tremulous movements are in fact small, high-frequency myoclonic jerks, induced by posture or action. They can be mild, but can also be more incapacitating. When present in the lower limbs, these may lead to gait disorders and even drop attacks. These tremor-like movements during action can be mistaken for essential tremor or epileptic seizures.
