		Opsoclonus myoclonus is a very rare syndrome that strikes previously normal infants, children, or adults, often occurring in conjunction with certain cancerous tumors,
		Many cases of opsoclonus myoclonus follow a bout of a viral illness such as infection with influenza, Epstein-Barr or Coxsackie B viruses, or after St. Louis encephalitis.
		When opsoclonus myoclonus occurs in adults, it is usually associated with tumors in the lung, breast, thymus, lymph system, ovaries, uterus, or bladder.

	MDVU Resource Library - Myoclonus - Pathophysiology
		In cortical myoclonus, a dysfunction at the level of the sensorimotor cortex may arise due to the distant effect of cerebellar pathology, resulting in decreased cortico-cortical inhibition; pathologic involvement of the cortex is not necessary.
		These results indicate that myoclonus due to corticobasal ganglionic degeneration may be due to reafference rather than corticospinal drive, which points to a subcortical origin of the movements with a disturbed interaction between sensorimotor cortex and subcortical structures.
		The pathophysiology of essential palatal myoclonus is unknown; however, secondary or symptomatic palatal myoclonus may be immunologic, psychogenic, or genetic in origin, or it may be related to trauma9 or a localized lesion within the brainstem or upper cerebellar peduncle.

		Myoclonus is defined as sudden, brief, shocklike involuntary movements caused by muscular contractions (ie, positive myoclonus) or inhibitions (ie, negative myoclonus, or asterixis) (1).
		Opsoclonus is defined as involuntary, repetitive, rapid conjugate eye movements (ocular saccades) that are irregular in amplitude and frequency and occur in all directions without an intersaccadic interval.
		Myoclonus and chorea are hyperkinetic movement disorders that confer a jerky appearance.

	Saccadic Nystagmus
		Opsoclonus essentially differs from flutter in that opsoclonus is oriented in any direction (horizontal, vertical, torsion), while flutter is generally always purely horizontal.
		Opsoclonus is nearly always caused by a neural tumor (a neuroblastoma) or a paraneoplastic syndrome (a tumor elsewhere in the body).
		Opsoclonus may also be caused by a viral infection of the brainstem or cerebellum, as well as autoimmune processes.

	MDVU Resource Library - Myoclonus - Treatment
		The most important step in treating myoclonus is to first identify and appropriately classify the subtype of the disorder because the pathology—and, therefore, treatments and outcomes—are cause specific in many cases.
		The guiding principles in the pharmacologic treatment of myoclonus are (1) to recognize that therapy is empiric, targeted at symptom relief, and (2) that, although polytherapy is often required, treatment should be instituted with a single drug.
		Surgical techniques that have been employed in the treatment of myoclonus include decompression of a peripheral injury in peripheral myoclonus20, removal of the compression lesion in spinal myoclonus21, thalamic stimulation for medically intractable inherited myoclonus-dystonia syndrome22,23, and excision of neoplasms in opsoclonus-myoclonus.

		"Opsoclonus" is an unusual disorder of eye movement in which both eyes dart involuntarily (dancing eyes).
		Myoclonus occurs most when movement is attempted, worsens with agitation or stimulation, but may be present at rest.
		When opsoclonus and myoclonus occur as separate disorders, they have many causes, but the combination is rather specific for tumors and infections.

	WE MOVE - Myoclonus - Pharmacologic Agents
		Although clonazepam and valproic acid are often used in the treatment of myoclonus, they have never been formally studied for this use.
		A trial of this drug is reasonable in most patients with myoclonus, particularly those with proven posthypoxic cortical myoclonus.
		Caution is urged with the use of these drugs because many may actually make myoclonic symptoms worse or may cause myoclonus in some patients.

	Opsoclonus Myoclonus Neuroblastoma Gabrielle's Garden (Site not responding. Last check: 2007-10-19)
		I was also diagnosed with an extremely rare disease called opsoclonus myoclonus syndrome that was caused by the cancer.
		The reason for this is children that have Neuroblastoma with Opsoclonus Myoclonus have a very small chance of the tumor being aggressive or reoccurring.
		The theory is the body's immune system is trying to destroy the tumor however the tumor and the brain must have similar properties, as the immune system cannot tell them apart and the brain is an innocent bystander caught in the "cross-fire" between the immune system and the tumor, which it is trying to destroy.

		The diagnosis of psychogenic myoclonus often requires electrophysiologic testing, including electromyography (EMG), electroencephalography (EEG), and back-averaging EEG-EMG to rule out physiologic causes.
		In myoclonus dystonia, arm involvement is prominent, and the legs are usually unaffected.

	Opsoclonus myoclonus syndrome (Site not responding. Last check: 2007-10-19)
		Opsoclonus myoclonus syndrome is a neurological disorder acquired in children as a result of the presence of a neuroblastoma (paraneoplastic syndrome) or, more rarely, a viral infection.
		Three out of the four following criteria must be present for diagnosis: opsoclonus (involuntary, rapid eye movements), ataxia/myoclonus, behavioural and sleep disorders and neuroblastoma.
		The most efficient methods for detecting this tumour are whole-body magnetic resonance imaging with gadolinium injection or helicoidal scanning centred on the paravertebral region.
