Myoclonus is usually classified physiologically to optimize treatment. Myoclonus is a precursor effect to myoclonus dystonia and most commonly begins in childhood or adolescence. [4] [5] Myoclonus is classified as cortical, subcortical, peripheral or spinal. Cortical myoclonus is the most common of these four and affects the upper limbs and face.
Myoclonus is a brief, involuntary, irregular (lacking rhythm) twitching of a muscle, a joint, or a group of muscles, different from clonus, which is rhythmic or regular. Myoclonus (myo-"muscle", clonus "spasm") describes a medical sign and, generally, is not a diagnosis of a disease.
Asterixis (more colloquially referred to as flapping tremor) is not actually a tremor, but rather a negative myoclonus.This movement disorder is characterized by an inability to maintain a position, which is demonstrated by jerking movements of the outstretched hands when bent upward at the wrist (which can be similar to a bird flapping its wings, hence the name "flapping tremor").
Causes painful defecation, constipation; may be complicated by encopresis or fecal incontinence. Cervical dystonia (spasmodic torticollis) muscles of the neck: Causes the head to rotate to one side, to pull down towards the chest, or back, or a combination of these postures. Blepharospasm: muscles around the eyes
It is a disease that presents Myoclonus as a sequela of hypoxic disorders in the brain due to asphyxiation and cardiopulmonary arrest. [ 2 ] [ 3 ] It is exacerbated by mental and physical anxiety such as intention, intentional movement, and tension.
Progressive Myoclonic Epilepsies (PME) are a rare group of inherited neurodegenerative diseases characterized by myoclonus, resistance to treatment, and neurological deterioration. [2] The cause of PME depends largely on the type of PME. Most PMEs are caused by autosomal dominant or recessive and mitochondrial mutations. [2]

The causes of MERRF syndrome are difficult to determine, but because it is a mitochondrial disorder, it can be caused by the mutation of nuclear DNA or mitochondrial DNA. [3] The classification of this disease varies from patient to patient, since many individuals do not fall into one specific disease category.
