The causes of cerebral thrombosis are as follows: 1, cerebral arteriosclerosis: cerebral arteriosclerosis leads to the formation of blood clots, such as hypertension, hyperlipidemia, and diabetes and other diseases, which can cause rapid progression of arteriosclerosis, in addition to the poor lifestyle can also lead to the progression of arteriosclerosis, such as obesity, smoking, long-term physical inactivity, and high mental stress.
