The common causes of vertigo in the elderly are as follows: 1. cervical spondylosis due to osteophytes and degeneration of intervertebral discs, narrowing of the vertebral space and compression of the vertebral artery, resulting in insufficient blood supply to the vertebral basilar artery and vertigo due to impaired circulation in the internal auditory artery of its branches; 2. hypertension due to elevated blood pressure and spasm of the small arteries, narrowing of the arterial cavity and insufficient blood supply to the brain and inner ear; 3. hypotension due to lower than normal blood pressure, which also affects the blood supply to the brain; 4. 4. Hyperviscosity can be diagnosed by blood rheological examination and comprehensive analysis. This disease slows down the blood flow and affects the blood supply to the important organs of the body, especially the brain, resulting in vertigo and weakness. 5. Sleep apnea syndrome is common, especially in the elderly and obese people. Severe snorers repeatedly experience apnea (longer than 10 seconds) during sleep and appear to hold their breath or even wake up, which is called nocturnal apnea syndrome. It causes the body to be in a state of long-term oxygen deprivation at night, while feeling dizziness, sleepiness, memory loss and other symptoms during the day; 6. Plant nervous disorders excessive fatigue, mental tension and anxiety, mood swings, etc. can induce vertigo by affecting the stability of the plant nervous system. In addition, diseases that easily cause vertigo include: traumatic brain injury, brain tumor, anemia, myocardial ischemia, drug poisoning, otosclerosis, etc. The four “constants” can effectively prevent and control senile vertigo. Patients with senile vertigo should be optimistic in their daily life, keep an open mind, and try to avoid anxiety, worry and tension. Secondly, always exercise. Often carry out some physical exercise appropriately, but the amount of exercise should not be too much, you can take a walk jogging, gymnastics and other ways to improve blood circulation. Third, often eat vegetarian. Diet should be light, do not eat greasy heavy food, eat more fresh vegetables and fruits rich in vitamins as long as attention to life conditioning, you can make the symptoms can be relieved. Fourth, often check. For the original hypertension should pay attention to the observation and adjustment of blood pressure, correct the specific value of blood pressure depends on the original blood pressure, and try to improve the blood supply to the brain to prevent the aggravation of vascular sclerosis.
