When people get old, various diseases start to “find” them, such as the “three highs” (high blood pressure, high blood sugar, high blood fat), and atherosclerosis. The health of the elderly in the family is the most concerned about the whole family. Atherosclerosis is a non-inflammatory lesion of the arteries, which can cause thickening and hardening of the arterial walls, loss of elasticity, and narrowing of the lumen, and there are three common types of atherosclerosis, calcification of the middle layer of the arteries, and small arteriosclerosis. Since the formation process of atherosclerosis is quite slow, it does not start to develop only in old age, but it is a vascular disease that appears with age. The pattern is usually that it occurs in adolescence and worsens and develops in middle and old age, with more men than women. The most important causes of atherosclerosis are hypertension, hyperlipidemia, and smoking. Other causes such as obesity, diabetes, physical inactivity, stress, advanced age, family history, irritability, and high intake of fatty foods and cholesterol-rich foods can also cause atherosclerosis. Cerebral atherosclerosis is a part of systemic atherosclerosis, which is caused by the thickening of the vessel wall and narrowing of the lumen, resulting in chronic ischemia of the brain parenchyma, causing the brain to lose its function, mainly the higher neural activity. Since cerebral atherosclerosis initially has no obvious conscious symptoms, it is difficult to grasp the condition by oneself. However, the arrival of any disease will have different signs and symptoms. It is important to pay attention when the following conditions appear in the elderly in the family: 1. Mental disorders: Most of them first appear headache, dizziness, heavy hair, stuffiness (tightness and pressure feeling in the head), followed by near memory loss, especially easy to forget names, numbers and recent events, but remember childhood or past events very clearly. 2, emotional abnormalities: patients are emotionally unstable, often agitated by the small things in life, temper tantrums, sadness, mood swings, and some patients may have emotional disorders such as anxiety, depression or fear. 3, sleep disorders: often have difficulty falling asleep, easy to wake up, dreamy, etc.. Some people need to take sleeping pills to fall asleep, and some people show insatiable sleep. 4.Decreased judgment: As the disease develops, patients have difficulty in thinking and associating, their ability to comprehend new things decreases, their work efficiency decreases, and they feel incompetent to do their jobs. 5.Abnormal action: Gait changes may occur in the middle and late stages of cerebral atherosclerosis, manifested as panic gait, small broken steps, slow, stiff or unstable walking and turning. 6, Parkinson’s syndrome: lack of facial expression, bending the body forward when standing upright, straight limb muscles and slightly flexed elbow joints, finger tremors in the form of rubbing pills, small pace and forward body lunge. 7, pseudobulbar palsy: manifested as increased muscle tone of the limbs, the appearance of difficult to self-control strong smile and strong cry, bitter smile similar indistinguishable, swallowing difficulties with salivation, etc. Cerebral arteriosclerosis is very likely to cause stroke and other problems, so early diagnosis and treatment play an active role in preventing further development of cerebral arteriosclerosis. Moreover, atherosclerosis is a slow pathological process, and if various risk factors can be effectively controlled and targeted treatment is carried out for a period of time, the existing lesions can be partially reversed or subside.
