Is sleep myoclonus curable?
Treatment. Sleep myoclonus is not considered serious or in need of treatment unless it interferes with sleep and/or someone’s quality of life. If it does, the condition may be treated with Xenazine (tetrabenazine), a drug often used to treat movement disorders such as Huntington’s disease.
Does pediatric myoclonus go away?
This is a relatively common form of myoclonus that usually starts in the first six weeks of life. This myoclonus starts as the infant falls asleep and stops when the child wakes up. This form of myoclonus usually goes away on its own without treatment.
What neurological disorders cause sleep myoclonus?
Nervous system conditions that result in secondary myoclonus include:
- Brain tumor.
- Huntington’s disease.
- Creutzfeldt-Jakob disease.
- Alzheimer’s disease.
- Parkinson’s disease and Lewy body dementia.
- Corticobasal degeneration.
- Frontotemporal dementia.
How common is benign neonatal sleep myoclonus?
This condition is fairly rare. According to the American Academy of Sleep Medicine, benign neonatal sleep myoclonus occurs in just under four out of 10,000 live births. The condition appears to be twice as common in males.
What is benign neonatal sleep myoclonus?
Benign neonatal sleep myoclonus (BNSM) is a self-limiting disorder characterized by neonatal onset myoclonic jerks during non-rapid eye movement (NREM) sleep, and consistent cessation with arousal with absence of concomitant electroencephalographic findings .
How common is benign myoclonus of infancy?
Benign myoclonus of early infancy is a rare condition characterized by nonepileptic spasms that may resemble the epileptic spasms seen in West’s syndrome. The spells in benign myoclonus of early infancy begin before age 1 year and are self-limited.
How is sleep myoclonus treated?
Examples of medication that can help treat sleep myoclonus include :
- antiseizure and anticonvulsant medications, such as clonazepam (Klonopin), phenytoin (Dilantin), and levetiracetam (Keppra)
- sedatives, such as barbiturates.
- 5-hydroxytryptophan, an amino acid in serotonin.
- botulinum toxin (Botox)
Does neonatal sleep myoclonus go away?
Since benign neonatal sleep myoclonus episodes and the disorder itself usually resolve on their own, no treatment is needed.
What causes benign myoclonus?
Abstract. Benign myoclonus of early infancy, first described by Fejerman and Lombroso, is a paroxysmal phenomenon of the first 2 years of life which occurs in neurologically healthy infants during wakefulness, and is usually triggered by excitement or frustration.
Is benign neonatal sleep myoclonus normal?
In benign neonatal sleep myoclonus, myoclonic jerks occur multiple times while the infant is sleeping. The condition is considered harmless, though without measuring brain waves it may be difficult to tell whether an infant has benign neonatal sleep myoclonus or epilepsy.
When do babies grow out of myoclonus?
Sleep myoclonus usually disappears after a period of weeks and has resolved in most cases by 3 months of age.
Is benign sleep myoclonus genetic?
Nocturnal myoclonus may represent a continuum; benign neonatal sleep myoclonus may be the most obvious and readily recognized manifestation, with diminished signs as the CNS matures, although this remains to be demonstrated. A genetic etiology is suspected, with reports of occurrence in multiple family members.
What are the signs and symptoms of benign neonatal sleep myoclonus?
The differential diagnosis of benign neonatal sleep myoclonus includes benign neonatal seizures, neonatal status epilepticus, typical hypnic jerks, and jitteriness.
What is benign sleep myoclonus of infancy (BSMI)?
Benign sleep myoclonus of infancy (BSMI) is characterized by repetitive myoclonic jerks that occur during sleep in neonates and infants. 3 Its diagnostic features include the observation of repetitive myoclonic jerks involving limbs, trunk, or whole body.
What is the prognosis of neonatal sleep myoclonus (NHS)?
Benign neonatal sleep myoclonus begins during the first week of life, diminishes in the second month, and is usually gone before 6 months of age, but has been reported to persist as long as 3 years in one patient and 4 years in another patient.
What is the prevalence of sleep myoclonus in NAS?
Sleep myoclonus was diagnosed in 52 (67%) of the infants with NAS and 2 (2.6%) of the controls (OR 26 [95% CI: 7-223], p < 0.001). Myoclonus appeared as early as day 2 and as late as day 56 of life (median day 6) and lasted for 1 to 93 days (median 13 days).
