Abstract：【Objective】To investigate the distribution of infarct location in patients with early PSDs after early cerebral infarction and its correlation.【Methods】From March 2008 to August 2017, 78 patients with cerebral infarction were selected and divided into PSD group (n=40) and non-depression group (n=38, PSND). All patients were scanned with MRI, and the distribution of cerebral infarction in both groups was analyzed, and the correlation between the location of cerebral infarction and the occurrence of PSD was analyzed.【Results】The proportion of infarction in the frontotemporal and parietal cortex, occipital cortex, brainstem and cerebellum in the PSD group was significantly higher than that in the PSND group, the difference was statistically significant (P<0.05). The distance between the infarct site and the left frontal pole and the right frontal pole in the PSD group were (2.47±1.33) cm and (2.94 ±1.55)cm, respectively, which were lower than that in the PSND group (3.28 ±1.46) and (3.14 ±1.41) cm, respectively. The distance between the infarct site and the left frontal pole in the PSD group was significantly smaller than that in the PSND group; the difference was statistically significant (P<0.05). From the analysis of the correlation coefficient, the order of correlation between each indicator and PSD from big to small was: brain stem and cerebellum>frontotemporal parietal cortex>occipital cortex>left frontal polar distance>multiple infarction>hippocampal amygdala>left frontal lobe>posterior part>right frontal lobe>right frontal polar distance>coronal area>anterior part of brain>basal nucleus area.【Conclusion】When the cerebral infarction is located in the brain stem and cerebellum and the frontotemporal parietal and occipital cortex with smaller left frontal pole distance, it is easy to appear early PSD, and the early PSD is related to the location of the infarct.
