Myoclonus
Understanding causes, types, and effective treatments for muscle jerks
What is Myoclonus?
Myoclonus refers to sudden, involuntary muscle jerks or twitches that can occur in one or more parts of the body. These brief, shock-like movements can range from mild twitches to severe, disabling contractions. Myoclonus can be a normal physiological response (like hiccups or sleep starts) or a sign of an underlying neurological disorder.

What's Causing Your Myoclonus
Identifying the underlying causes of myoclonus allows us to target treatment effectively for lasting results.
Epilepsy
Very CommonAbnormal electrical activity in the brain triggers myoclonic jerks, often as part of seizure disorders.
Brain Injury
CommonDamage to brain tissue from trauma, stroke, or surgery can disrupt motor control pathways.
Neurodegenerative Diseases
CommonProgressive loss of neurons in conditions like Alzheimer's, Parkinson's, or Huntington's can cause myoclonus.
Metabolic Disorders
Less CommonLiver failure, kidney failure, or severe electrolyte imbalances can affect brain function.
Medications
Less CommonSome medications (antibiotics, antidepressants, anticonvulsants) can cause myoclonus as side effects.
Infections
Less CommonBrain infections like meningitis or encephalitis can cause myoclonus.
