高血压患者合并腔隙性脑梗塞的发生率非常高,但小范围的脑梗塞,临床表现十分隐蔽,如果不加注意,很难察觉,因为它引起的症状轻微,或者不具有特殊性,如头晕、耳鸣、失眠、情感变化,以及记忆力进行性下降等。这些症状常常被误认为由于年龄增长,或其他疾病所致。高血压之所以易引起腔隙性脑梗塞,原因在于长期增高的血压会引起动脉硬化,导致动脉内皮细胞损伤、血小板聚集、血栓形成等一系列病理变化,从而引起脑梗塞发生。因此,高血压患者一旦发现短时期内出现明显的记忆力下
The incidence of lacunar infarction in hypertensive patients is very high, but small-scale cerebral infarction, the clinical manifestations of very subtle, if not pay attention, it is difficult to detect because it causes mild symptoms or no special, such as Dizziness, tinnitus, insomnia, emotional changes, and progressive decline in memory.
