A study of head and eye movement in spasmus nutans.

Spasmus nutans and congenital ocular motor apraxia with cerebellar vermian hypoplasia.

BACKGROUND Spasmus nutans and congenital ocular motor apraxia share clinical characteristics. However, their development in a patient with cerebellar vermian hypoplasia has not been previously described. OBJECTIVE To report spasmus nutans and congenital ocular motor apraxia in a child with cerebellar vermian hypoplasia. DESIGN Case report. SETTING Tertiary-care hospital. Patient A 7-year-...

Spasmus nutans. A quantitative prospective study.

Spasmus nutans includes ocular oscillations, head nodding, and anomalous head positions. No quantitative longitudinal study verifying the natural history of this self-limited condition has appeared in the literature. Using infrared oculography, we prospectively examined the eye movements of otherwise neurologically normal infants in whom a diagnosis of spasmus nutans had been made. At this writ...

A Case of Stereotyped Repetitive Movements

Stereotyped repetitive movements are defined in ICD-9 as "disorders in which voluntary repetitive stereotyped movements which are not due to any psychiatric or neurological condition-constitute the main feature. Includes head banging, spasmus nutans, rocking, twirling, finger-flicking mannerisms and eyepoking. Such movements are particularly common in cases of mental retardation with sensory im...

Diagnosing children presenting with asymmetric pendular nystagmus.

Horizontal asymmetric nystagmus usually occurs in one of three situations: secondary to an intracranial lesion, with monocular visual loss, or as part of the triad that constitutes the diagnosis of spasmus nutans (asymmetric nystagmus, abnormal head posture, head shake). Clinical records of 277 children, presenting with congenital nystagmus over an 8-year period were reviewed. Nystagmus was asy...
