Cortical reflex myoclonus is thought to be a type of epilepsy that originates in the cerebral cortex – the outer layer, or "gray matter", of the brain, responsible for much of the information processing that takes place in the brain. In this type of myoclonus, jerks usually involve only a few muscles in one part of the body, but jerks ...
Reticular reflex myoclonus is a generalized form of epilepsy originating from the brain stem. Jerks associated with the disorder can affect all muscles on the body or be selective in certain areas. [6] Jerks can be triggered by voluntary movement or be stimulus-selective. [6]
Cortical myoclonus is the most common of these four and affects the upper limbs and face. Myoclonus dystonia has been characterized under subcortical origin, specifically under nonsegmented myoclonus or brainstem myoclonus. Symptoms within this classification include the startle response and reticular reflex myoclonus.
Photic stimulation may also be used to elicit myoclonus, especially cortical reflex myoclonus when present in photo-sensitive forms. IPS may be used to stimulate the visual system for patients with amblyopia. This system uses a visual stimulus that is usually red in color with a frequency of about 4 Hz to stimulate the neural pathway between ...
Reflex Epilepsy (JS) is a form of epilepsy usually categorized within the spectrum of genetically linked Generalized Epilepsy (GGE). While EM (Epileptic Myoclonus) is commonly acknowledged as a type of seizure, the formal recognition of JS as a separate medical entity by the International League Against Epilepsy (ILAE) has not yet occurred.

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.
Non-epileptic seizures (NES), also known as pseudoseizures, non-epileptic attack disorder (NEAD), functional seizures, or dissociative seizures, are paroxysmal events that appear similar to an epileptic seizure, but do not involve abnormal, rhythmic discharges of neurons in the brain. [1]
Jeavons syndrome is a type of epilepsy.It is one of the most distinctive reflex syndromes of idiopathic generalized epilepsy characterized by the triad of eyelid myoclonia with and without absences, eye-closure-induced seizures, EEG paroxysms, or both, and photosensitivity.
