Background:
Acute confusional migraine (ACM) is considered a rare migraine variant primarily seen in children and adolescents.
Patients And Methods:
We present a series of eight adults and two adolescents suffering from migraine attacks associated with transient confusional states.
Results:
Eight patients reported two or more such attacks. One of them reported mild head trauma in the past. One patient reported mild head trauma as a possible trigger. Further investigations were unremarkable in all patients and did not suggest underlying structural abnormalities, epilepsy or cerebrovascular disease. In none of these patients did we find another cause to explain the observed phenomenon.
Conclusions:
Based on this series of patients, we suggest expanding the concept of confusional migraine from the paediatric population to adults. The temporal course of the confusion as well as the association with visual and other aura symptoms suggest cortical spreading depression as the underlying pathophysiology.

Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
