DT imaging revealed asymmetric anatomic changes in spinal cord NAWM, which corresponded to asymmetric electrophysiological deficits for both arms and legs, and reflected a specific structure-function relationship in the human spinal cord.

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.

Headache is a common complaint among patients seeking medical assistance. The differentiation between a primary headache disorder versus headache as a symptom of a serious underlying disease is of crucial importance. Dissections of the carotid or vertebral arteries frequently present with headache and can result in ischemic stroke. Rarely, headache or neck pain is a presenting symptom in patients with spontaneous proximal aortic dissection. We report on a 53-year-old man with a history of migraine with aura, who was admitted to the hospital because of severe frontal headache and neck pain. An anterior chest pain lasting for 10 minutes the day before and a diastolic heart murmur suggested a proximal aortic dissection, which was confirmed by transesophageal echocardiography. Patients with proximal aortic dissection rarely have headache or neck pain, reflecting the low incidence of carotid artery involvement in this disease. However, differentiation between an isolated cervical artery dissection and a proximal aortic dissection extending to the carotid arteries is pivotal, since treatment options are vastly different.
