Anonymous users2024-02-06Recommendation: Dizziness is a common symptom and not a stand-alone condition. Therefore, we can classify and describe the diseases that cause dizziness, so that everyone can have a deeper understanding of "dizziness".
1 Rotational vertigo can be divided into two categories: peripheral vertigo and central vertigo.
1) Peripheral vertigo: refers to vertigo caused by the labyrinth of the inner ear or the lesion of the vestibular nerve. It is commonly seen in Meniere's disease), labyrinthitis (caused by drugs such as streptomycin or gentamicin), and vestibular neuritis.
2) Central vertigo: refers to vertigo caused by lesions of the brainstem, cerebellum, brain and spinal cord. It is commonly found in vertebrobasilar insufficiency, intracranial tumors, intracranial infections, multiple sclerosis, vertigo epilepsy, and traumatic vertigo.
2 General vertigo.
1) Cardiogenic vertigo: common in arrhythmia, cardiac insufficiency, etc.
2) Cormonale vertigo: can be seen in pulmonary insufficiency caused by various causes.
3) Oculogenic vertigo: common in refractive error, fundus arteriosclerosis, hemorrhage and ophthalmoplegia.
4) Hypertensive vertigo: high blood pressure or low blood pressure can cause vertigo.
5) Others: anemia, cervical spondylosis, acute fever, gastroenteritis, endocrine disorders and neurosis, etc.
1 Anemia If the elderly have dizziness, fatigue, and paleness, they should go to the hospital for an examination to see if they are anemic. Older people are prone to anemia if they don't pay attention to nutritional care. In addition, anemia can be secondary to indigestion, peptic ulcer, gastrointestinal bleeding, and chronic inflammatory diseases in older patients.
2 High blood viscosity Hyperlipidemia, thrombocythemia, etc. can make the blood viscosity high and the blood flow slow, resulting in sufficient blood supply to the brain, and symptoms such as easy tiredness, dizziness, and fatigue occur. Among them, there are many reasons for hyperlipidemia, the most important of which is the irrational diet structure. 3 Cerebral arteriosclerosis Patients feel dizzy, and often suffer from insomnia, tinnitus, emotional instability, forgetfulness, and numbness in the limbs.
Cerebral arteriosclerosis makes the inner diameter of blood vessels smaller, and the blood flow in the brain decreases, resulting in insufficient blood supply and oxygen supply to the brain, causing dizziness. 4 Cervical spondylosis often presents with neck tightness, limited flexibility, occasional pain, numbness of fingers, coldness, and a feeling of heaviness. Cervical hyperplasia compresses the vertebral arteries in the neck, resulting in insufficient blood supply to the brain, which is the main cause of dizziness caused by the disease.
5 Hypertension In addition to dizziness, hypertensive patients are often accompanied by discomfort such as bloating, palpitation, irritability, tinnitus, and insomnia. 6 Heart disease In the early stage of coronary heart disease, some people may feel headache, dizziness, weakness in the limbs, and difficulty concentrating. It is mainly caused by atherosclerosis of the coronary arteries of the heart, resulting in insufficient blood supply and dizziness.
1.The best solution to dizziness is prevention. The elderly should have regular examinations of blood pressure, heart sound, heart rhythm, blood routine, blood lipids, blood viscosity, electroencephalogram, cerebral blood flow chart, neck X-ray, etc., to prevent problems before they occur

Anonymous users2024-02-04It generally refers to sudden fainting, also known as fainting or syncope. Fainting is a sudden and transient loss of consciousness that lasts from a few seconds to a few minutes, and the onset is caused by a temporary lack of blood or oxygen supply to the brain, and the recovery is relatively fast. Coma, on the other hand, is a prolonged loss of consciousness that makes recovery slow and difficult.
The causes of fainting are: 1 Reflex syncope: 1 Vasosuppressive syncope - the most common, accounting for more than 50%.
Syncope is often induced by fatigue, fasting, poor ventilation, and mental factors (nervousness, fear, pain); Prodromal symptoms such as transient dizziness, dizziness, weakness, and limb weakness before syncope; Syncope is accompanied by slowed heartbeat, decreased blood pressure (reflexive increase in the later stage), paleness, etc., and the recovery is rapid without obvious sequelae. 2 Orthostatic hypotension - often occurs when the supine position is converted to an upright position, and can also occur when standing for a long time, and the blood pressure drops during syncope without obvious changes in heart rate.
3 Micturition syncope - mostly in young and middle-aged men, syncope often occurs during or after urination. 4 Carotid sinus syncope – seen in middle age and above, syncope is associated with a sudden turn of the head. 2. Cardiac syncope:
Patients often have a history of heart disease, which is often caused by severe arrhythmias, such as high tachycardia, bradycardia (less than 40 points) or asystole, valvular heart disease, obstructive cardiomyopathy, atrial myxoma, etc., resulting in cerebral insufficiency and syncope. 3. Cerebral syncope: Common cerebrovascular diseases such as cerebral arteriosclerosis, cerebral vascular stenosis or obstruction, transient cerebral ischemia, pulseism, epilepsy, craniocerebral injury, etc.
4. Metabolic and hematologic syncope: Hypoglycemic syncope is common, the seizures are related to fasting, and can also occur 2 to 4 hours after a meal, syncope often occurs slowly, and recovery is also slow. There is no significant change in blood pressure and pulse at the time of attack, and blood glucose levels often do not match symptoms.
Severe anemia can also cause fainting. 5. Psychogenic syncope: seen in hysteria, hyperventilation, etc.

Overwork or poor rest: Nowadays, people are under a lot of work pressure, and many people sleep for a very short time and have very low sleep quality, which leads to changes in blood pressure fluctuations and causes the formation of cerebral thrombosis. >>>More

Sometimes when we adults watch TV, we like to hold our children, or put the baby with the cradle next to us, and babies and toddlers tend to look sideways at the TV under the attraction of TV sound and images. Sometimes he will look at it as long as an adult looks at it, and it is often in the same position. Over time, it will naturally cause strabismus. >>>More
