How do myoclonic seizures present?

Myoclonic seizures present as sudden, brief muscle contractions or jerks. These movements are very rapid and last only a fraction of a second, can involve a single muscle or multiple muscles, and often occur in clusters. Consciousness is usually preserved during the jerks, and the person may not have a prolonged interruption of awareness. In contrast, prolonged loss of consciousness describes tonic-clonic seizures with a longer-lasting impairment, stiffening of the head and trunk for minutes points to tonic seizures, and postictal confusion is a common after-effect after convulsive seizures rather than a defining feature of myoclonus. So, the hallmark presentation is the brief, sudden muscle jerks.
