Sandifer Syndrome Clinical Presentation

History
Sandifer syndrome is most commonly mistaken for seizures.[3, 5, 6] The child typically appears to have an alteration in mental status associated with the tonic posturing.
- A relationship with feeding may suggest a diagnosis of Sandifer syndrome, which commonly occurs after feeding.
- The child may have a sudden rotation of the head and neck to one side and the legs to the opposite side with a stretched out appearance. Typically, the back is arched posteriorly with hyperextension of the spine and elbows may be flexed and held posteriorly with hyperextended hips. Torticollis may be present.[8, 5, 6] Although the intermittent stiff tonic posture and periods of crying and apparent discomfort may suggest seizures, in many cases the rhythmic clonic component, which may be present in seizures, is not described.
- Various stiff, bizarre postures can be observed.
- Typically, the duration of the posture is 1-3 minutes.
- This brief, paroxysmal pattern of posturing accounts for the fact that the movement observed in Sandifer syndrome may be mistaken for seizures.
- During the posture, the infant may become very quiet or, less commonly, become very fussy. Fussiness and evident discomfort is most commonly observed as the posture abates
- If a significant volume of gastroesophageal reflux is observed, even without actual vomitus, some infants and children may manifest evidence of respiratory tract irritation as well, including cough, wheezing, and stridor, depending on the degree and volume of reflux.[9]
Physical
In children with Sandifer syndrome without mental impairment, the examination findings are normal. Children with Sandifer syndrome with mental impairment often have evidence of spasticity and may be diagnosed with cerebral palsy.[10]
- Sandifer syndrome in infants is most commonly associated with normal examination findings.
- Sandifer syndrome in older children may be associated with mental impairment.
Causes
Dysfunction of the lower esophagus is thought to be the most common precipitating factor. In some children, a cause cannot be found.
- Gastroesophageal reflux disease (GERD) with varying degrees of esophageal inflammation
- Dysmotility of the esophagus: Esophageal dysmotility, characterized by low-amplitude waves, lack of normal propagation, and low lower esophageal sphincter (LES) pressure, is not the cause but most likely the consequence of esophagitis.
