Özet

Objective: Survivors of patients with artery of Percheron infarction (API) often have a prolonged and disabling form of cognitive impairment that remains insufficiently characterized. We aimed to examine the clinical and cognitive features of API in the short and long term after stroke. Methods: We reviewed 6400 patients with a first-ever stroke included in the Stroke Registry between 2011 and 2021. The diagnosis of API was based on clinical diagnosis and imaging confirmation. All patients underwent neuropsychological assessment at hospital stay and 1 year after stroke. A z-score of each patients' cognitive test point was calculated, and a z-score inferior to 2 was considered as pathological. Results: Of the 10 patients enrolled, all had cognitive impairment, consciousness, and behavioral disorders at stroke onset. Six patients had pure bilateral thalamic involvement while four had bilateral thalamic and rostral midbrain involvement. At 12 months, 50% of patients had global mental state scores 2 SD below the population mean (z-score mean +/- SD, -2.17 +/- 0.4). Most of the prefrontal cortex cognitive processes including executive functions such as planning and cognitive control (z-score mean +/- SD, -3.92 +/- 0.3), processing speed (-4.42 +/- 0.5), working memory (-3.97 +/- 0.3) were severely impaired at stroke onset. Especially in patients with thalamic and rostral midbrain involvement, deficiencies in executive function (z-score mean +/- SD, -2.60 +/- 0.4), processing speed (-2.22 +/- 0.5), working (-3.76 +/- 0.4), and episodic memory (-2.23 +/- 0.3) continued 12 months after stroke. Conclusions: The occlusion of the artery of Percheron results in severe behavioral and cognitive disorders in the short and long term after stroke.
