Spasmus Nutans

PURPOSE: To investigate the nystagmus of twin brothers presenting with spasmus nutans later diagnosed as Bardet-Biedl syndrome. METHODS: The twins presented at the age of 14 months with a presumed diagnosis of spasmus nutans. [ncbi.nlm.nih.gov]

Optometry Abstract Spasmus nutans is a rare form of nystagmus presenting in infancy with a triad of asymmetric nystagmus, head nodding, and torticollis. [aaopt.org]

The pupils reacted sluggishly to light; however, no relative afferent pupillary defect was present. The nystagmus was present, and was similar to that seen previously, but diminished in frequency. [healio.com]

  • Pediatric Disorder

    A triad of ocular oscillations, head titubation, and torticollis characterizes spasmus nutans, a rare and idiopathic pediatric disorder. All three are not required for diagnosis, with torticollis being less common. [shmabstracts.com]

  • Nystagmus

    When the cyst was shunted the nystagmus lessened. Recent studies suggest that the head nodding and anomalous head position are adaptive mechanisms that compensate for the nystagmus and not pathological in themselves. [ncbi.nlm.nih.gov]

  • Pendular Nystagmus

    We used ocular motility recordings to identify the characteristics of a rare combination of conjugate, horizontal jerk, and pendular nystagmus in a 9-year-old boy. [ncbi.nlm.nih.gov]

    Definition Spasmus nutans is a specific type of pendular nystagmus of infancy accompanied by head bobbing and occasionally by abnormal position of the neck. [health.am]

  • Involuntary Movements

    It is not clear whether head nodding is a compensatory mechanism to control the nystagmus or an involuntary movement of pathologic origin. [ncbi.nlm.nih.gov]

    Overview Quick Reference A combination of symptoms including a slow nodding movement of the head, nystagmus (involuntary movements of the eyes), and spasm of the neck muscles. It affects infants and it normally disappears within a year or two. [oxfordreference.com]

    When to Contact a Medical Professional Call for an appointment with your health care provider if your child has rapid involuntary movements of the eyes or head nodding. [coordinatedhealth.com]

    There were no associated symptoms of gait disturbance or vertigo or hearing deficit. However, parents admitted that his scholastic performance was poor due to illegible handwriting. [ncbi.nlm.nih.gov]

    A small literature exists about this called "matitutional vertigo". Downbeating nystagmus can be elicited by the head-shaking test. [tchain.com]

    Maternal alcohol abuse ( 12 ) and child abuse/neglect ( 13 ) have also been implicated as risk factors for SN. [journals.lww.com]

Diagnosis: Laboratory investigation usually is not required for spasmus nutans.Exceptions include workup for metabolic or infectious etiology in congenital cataracts, serology in suspected toxoplasmosis, toxicology in optic atrophy, endocrine assay for [medigoo.com]

It is necessary for this kind of nystagmus to perform a complete neurological and endocrinological workup. [intechopen.com]

Tests may include: CT scan of the head MRI scan of the head Treatment Return to top The benign form of spasmus nutans requires no treatment. Other conditions causing spasmus nutans must be treated individually. [rachel.education.gov.ck]

Spasmus nutans carries an excellent prognosis with 20/50 vision or better in most. A higher incidence of strabismus and amblyopia is associated in followed cases compared to controls. [shmabstracts.com]

Fortunately, for patients with the classic findings of spasmus nutans and a negative MRI, the prognosis is very good. [mattweedmd.com]

Outlook (Prognosis) Usually, this disorder goes away on its own without treatment. Possible Complications There are usually no complications. [coordinatedhealth.com]

The purpose of our study was to record and characterize the long-term prognosis of children diagnosed with spasmus nutans. Methods : All patients under the age of 21 years with a diagnosis of spasmus nutans were included. [tandfonline.com]

Expectations (prognosis) Usually, there is a spontaneous resolution. Complications There are usually no complications. [health.am]

Summary Epidemiology The prevalence of SN is unknown. [orpha.net]

Epidemiology The precise incidence and prevalence of spasmus nutans are unknown, but it is considered rare. Correlation of demographic and socioeconomic factors has been reviewed since the early 1900s. [aao.org]

Accurate simultaneous recordings of eye and head movements are required to understand the pathophysiological significance of these head oscillations. [ncbi.nlm.nih.gov]

[…] years, and is generally quoted as 6-12 months of age. 6 Though initially thought to resolve between 3 and 6 years of age, 7 more recent evidence from long-term follow up suggests there may be a persistence of subclinical nystagmus up to age 12 years. 8 Pathophysiology [aao.org]
