• Pediatric emergency medicine specialist shares insights on the topic.

The Case

• An 18-month-old boy presented with ataxia, unable to keep his head up, sit, or stand, and began vomiting.
• Previously healthy except for recurrent otitis media and viral-induced wheezing.
• The decision to take the child to the emergency department (ED) was based on acute symptoms.

• Less common causes include cerebellitis, encephalitis, brain tumors, and labyrinthitis.

Importance of History and Physical Examination

• A detailed history and physical exam are essential in diagnosing ataxia.
• Key factors include time course, recent infections, signs of increased intracranial pressure, and toxic exposures.
• Look for signs such as bradycardia, hypertension, vomiting, and overall appearance.

Diagnostic Workup

• Initial tests include point-of-care glucose and neuroimaging for concerns about trauma or increased intracranial pressure.
• MRI is preferred for posterior fossa abnormalities,
