What triggers myoclonic seizures?

The most common triggers are lack of sleep and too much stress. Drinking alcohol, which can lead to too little sleep and fatigue, is the strongest trigger of myoclonic jerks and tonic-clonic seizures. Flickering lights can also trigger seizures for some people.

How is myoclonus diagnosed?

Doctors diagnose myoclonus based on symptoms and do blood tests, electromyography, and/or magnetic resonance imaging to identify the cause. The cause of myoclonus is corrected if possible, but if the cause cannot be corrected, certain antiseizure drugs or clonazepam (a mild sedative) may lessen symptoms.

Does anxiety cause myoclonus?

Some types of neurotransmitters will “tell” your muscles to move. When you have anxiety, neurotransmitters may be released even when there’s no clear reason for them to be released. This is what can cause anxiety twitching. Another reason anxiety can cause muscle twitching is because it can cause you to hyperventilate.
