Acute confusional migraine in children and transient global amnesia in adults share a number of similar clinical manifestations. Acute confusional migraine in 6 children (mean age: 11.7 years; range: 7.5-17 years) was characterized by transient episodes of amnesia and acute confusion lasting 1-12 hours. Episodes were preceded by headache and vomiting in 4 patients. In 2 patients acute confusional migraine was the initial symptom. A history of preceding trivial head injury was reported in 3 patients and migraine in 4. Urine and serum drug screens were negative. Cerebral imaging studies and interictal electroencephalograms were normal. Ictal electroencephalograms in 3 patients revealed diffuse or bioccipital delta wave slowing. Recurrent episodes of acute confusional migraine occurred in 2 children during 1-3 years of follow-up. The clinical manifestations of acute confusional migraine in this series of children are similar to those reported in transient global amnesia. The similarity of the clinical manifestations of acute confusional migraine in children and transient global amnesia in adults suggests that these disorders may share a common pathophysiology.

Acute confusional migraine is a rare migraine variant primarily seen in childhood that lacks standardized diagnostic criteria. Acute symptomatic treatment for this disorder has not been established. We report 2 patients having a total of 6 episodes of acute confusional migraine where the symptoms resolved with prochlorperazine with variable success. Intravenous prochlorperazine was highly effective in 3 out of 4 episodes.

Acute confusional migraine (ACM) is recognized as a rare, but highly disabling migraine equivalent, mostly reported in children and adolescents. Herein we describe the case of a 12-year-old girl admitted to hospital for an acute confusional state and severe psychomotor agitation, associated with a pulsating headache and nausea, which turned out to be a manifestation of ACM. The girl was discharged on topiramate prophylaxis, titrated up to 75 mg/die; no recurrence of confusional and/or headache episodes has been reported over the last 14 months to date. Due to the rarity of this clinical entity, only anecdotal reports about acute and prophylactic treatment of ACM are available in the literature. The case reported herein suggests that topiramate seems to be effective in ACM prophylaxis, although a longer observation period in our patient and more cases are needed to confirm any long-term clinical benefit.

Background. Acute confusional migraine (ACM) is a rare variant of migraine, mainly prevalent in children and adolescents. It is not currently indexed as a distinct variant of migraine likely since only a few cases were reported in the adult population. We report a case of delayed ACM diagnosis in a young man and present a concise-related literature review. Case Presentation. A thirty-eight-year-old man with a past medical history of migraine, not on any treatment, presented with headaches accompanied by confusion. Over a two-year period before the current presentation, he experienced two episodes of confusion, which required hospital admission for evaluation: once mislabeled as a psychiatric illness and diagnosed as a migrainous infarct in the second hospitalization. In the current presentation, he reported a similar history of headache accompanied by confusion. The examination was remarkable for disorientation; otherwise, no focal deficit was elicited. Laboratory testing, cerebrospinal fluid, and neurological imaging were all unremarkable. His symptoms improved spontaneously within less than twenty-four hours, similar to his previous presentations. After two-year history of episodic confusion and after excluding other plausible causes of confusion, guided by proposed diagnostic criteria, we diagnosed him as a case of ACM. The patient remains well at the follow-up of two months after discharge. Discussion and Conclusion. ACM is a rare variant of migraine and is often a challenge for clinicians to diagnose appropriately. Until recent years, the disease was thought to be limited to children and adolescents. However, recently few reports also expanded the incidence of this entity to the adult population. There is a significant gap in knowledge about proper identification and treatment of this condition, leading to delayed or overlooked ACM diagnosis. Moreover, the recent edition of the International Classification of Headache Disorders (ICHD-3) does not account for this entity, thereby further adding to physicians' lack of awareness regarding this migraine subtype. The authors emphasize that clinicians be aware of this entity and adequately utilize the existing proposed diagnostic criteria for ACM until standardized and validated tools are available. We also believe that this entity should be acknowledged in the subsequent migraine guidelines and classifications.
