Forgetfulness as the primary presenting symptom of type A acute aortic dissection

Acute aortic dissection (AAD) is the most common lethal disease affecting the aorta. Neurological symptoms have been linked to AAD in some patients. Although aortic dissection patients have previously been shown to present with neurological symptoms, AAD with forgetfulness as the first manifestation is extremely rare. To increase the awareness of AAD among clinicians, we report the first case of a male Chinese patient with AD presenting with forgetfulness as the initial symptom. A 53-year-old man presented to the emergency department with forgetfulness. Based on the concept that "time is brain," stroke was initially considered in the differential diagnosis. The patient underwent emergency coronary angiography and was diagnosed with acute myocardial infarction. After contrast-enhanced computed tomography angiography, the patient was finally diagnosed with AAD. Because valuable time was lost in diagnosis rather than treatment, optimal timing for surgery missed. The patient died following an aortic dissection rupture while waiting for emergency surgery. When forgetfulness cannot be completely accounted for in patients presenting with acute myocardial infarction, AAD should be considered. We believe that this case report contains a worthwhile clinical lesson for clinicians.
