Differentiating these two aetiologies remains a diagnostic challenge with critical therapeutic implications. We aimed to compare the clinical profiles, imaging characteristics and outcomes of TAK- versus LAA-related stroke to provide insights for diagnosis and management.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Patients and methods<\/jats:title>\n                    <jats:p>We conducted a multicentre comparative study using nationwide prospective registry cohorts in China. Among 926 patients with TAK, 80 patients with stroke were included. In addition, 372 patients with LAA-related stroke were selected from the China National Stroke Registry-III cohort (n=14\u2009146). Clinical and imaging characteristics, traditional stroke risk factors and outcomes were analysed and compared. Subgroup analyses were performed according to the presence of atherosclerosis in TAK.

Furthermore, patients with TAK tended to show distinct imaging features, including predominant extracranial artery involvement and anterior circulation infarctions located in the subcortical\/deep white matter. Among patients with TAK-related stroke, those with coexisting atherosclerosis were older, had longer disease duration and had a greater risk of supra-aortic complications and a higher rate of endovascular interventions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study highlights distinct clinical and imaging profiles between TAK- and LAA-related strokes.
