Background: Acute confusional state associated with migraine in adults is an infrequent entity. Around 30-60% of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) patients get affected by migraine attacks-the majority with aura-often as the first symptom of the disease. Acute confusional state during migraine has been rarely described in CADASIL patients and a complete neuropsychological assessment during the acute phase has never been conducted so far.
Case summary: We here describe the clinical and neuropsychological features of two distinct episodes of ACM in a 54-year-old female with CADASIL. EEG recording during acute confusional migraine and after attack resolution and neuroimaging has been reported.
Discussion and literature review: This paper also reports a literature review on the topic of ACM in CADASIL highlighting a lack of adequate knowledge about this entity among clinicians and prompting further larger studies to explore its incidence and characteristics.
