The patient has headache and weakness, and it is considered that the patient may be caused by insufficient cerebral blood supply. It is suggested that the patient can go to the hospital for examination, do CT of the head to observe whether there is cavernous cerebral infarction or not, and transcranial Doppler ultrasound can be done to observe the situation of blood flow rate in the patient’s brain, and whether there is any slowing down of the blood flow rate. In addition, the patient can also do the laboratory tests of blood lipid, blood sugar and blood viscosity. Due to atherosclerosis, the viscosity of blood is increased and the symptoms of insufficient cerebral blood supply appear. The patient can be treated with medicines to improve blood circulation, such as intravenous drip of proprietary Chinese medicines, for example, thromboxane or danshen chuanxiongzine, etc., or oral medicines to lower blood lipids, for example, Lipitor tablets.
