Introduction
Acute confusional migraine (ACM) is a rare disorder characteristic of pediatric patients. Our objective was to describe the clinical characteristics of patients diagnosed with ACM who visited our pediatric emergency department (PED).
Methods
This study was a retrospective review of children who presented to our PED between January 2012 and December 2022 with a discharge diagnosis of ACM.
Results
During the study period, 23 patients were enrolled: 11 males (47.8%) and 12 females (52.2%); median age was 10.8 years (IQR: 8.3–13.6). Eight patients reported a history of headache. The median length of stay of PED was 4.7 h. Onset was abrupt (less than 12 h) in 100% of cases. Changes in the level and content of consciousness occurred in 47.8% and 91.3% of patients, respectively; confusion (73.9%) was the most common neurological manifestation. Eighteen patients had urgent brain CT scans, none showing pathological findings. Four patients required benzodiazepines to control their psychomotor agitation. Nine patients were hospitalized, including one in the intensive care unit. Two patients underwent MRI and one patient underwent EEG during hospitalization, with normal results.
Discussion
ACM is a rare condition in pediatric neurology characterized by acute onset of confusion or altered mental status before, during, or after migraine headache. Clinical features overlap with other neurological disorders, making diagnosis challenging. To improve the diagnosis, treatment, and research of AMC, it is essential to include it in the International Classification of Headache Disorders and establish standardized diagnostic criteria.
