Spectrum of complicated migraine in children: A common profile in aid to clinical diagnosis

Table 2 Lists the frequency of the individual syndromes of complicated migraine reported by the select retrospective studies[7-9]

Study type	Ref.	No. of patients	Frequency of the individual syndromes of complicated migraine reported
Retrospective	[7]	111	Migraine variants 24.3%, basilar type migraine 6.3%, benign paroxysmal vertigo (5.4%), hemiplegic migraine (3.6%), acute confusional migraine (2.7%), benign paroxysmal torticollis (2.7%), typical aura without headache (1.8%), abdominal migraine (1.8%), Alice in Wonderland syndrome (0.9%), ophthalmoplegic migraine (0.9%), and cyclical vomiting (0.9%)
Retrospective	[8]	674	Migraine variants 5.6%, abdominal migraine 39%, benign paroxysmal vertigo 38%, confusional migraine 13%, aura without migraine 9%, paroxysmal torticollis 5%, and a single child with cyclic vomiting
Retrospective, adults in Hyperacute Stroke Units	[9]	375	Conditions other than stroke 31%, which included 22% migraine, 14% functional neurological disorder, 12% syncope, and 6% seizure. In contrast to stroke patients, they tend to be younger, likely to have a brain MRI performed, and had a shorter length of hospital stay

This should be noted that no alternating hemiplegia of childhood and retinal migraine were reported in these studies. MRI: Magnetic resonance imaging.
