Dizziness is a symptom caused by the disruption of our body's sense of balance, and is divided into peripheral dizziness caused by ear problems and central dizziness caused by brain problems.
Peripheral dizziness occurs mostly due to abnormalities in the vestibular organs of the ear, and often improves over time. Typical examples are otolithiasis, vestibular neuropathy, and Meniere's disease. On the other hand, central dizziness is associated with structural abnormalities in the brain such as stroke, brain tumor, and cerebrovascular disease, requiring immediate diagnosis and treatment.
Lee Min-young, director of the Center for Brain and Neurology at Incheon Nanuri Hospital, said, "A dizziness is not a single disease, but a complex condition that appears as a symptom of several diseases. Especially if dizziness is repeated or accompanied by neurological symptoms such as speech disorders, double vision, and limb numbness, central causes such as stroke should be suspected, not just ear diseases."," he stressed.
Otolithiasis, a representative disease of peripheral dizziness, occurs due to problems with the cevancreatic duct and otolith organs, which are responsible for the sense of equilibrium in the ear. I changed my head position or lay down When you wake up, you suddenly feel dizzy, but it usually improves over time. Epileptic neuropathy is caused by damage to the vestibular nerve due to viral infection or inflammation, and causes severe dizziness and vomiting. Meniere's disease, another disease, is caused by an excessive amount of lymph fluid in the ear, accompanied by dizziness and tinnitus or hearing loss.
On the other hand, central dizziness is caused by blood flow disorders or structural abnormalities in the brain. Stroke, cerebral hemorrhage, cerebellar lesions, etc. are typical examples, and serious neurological symptoms such as speech impairment, blurred vision, and paralysis of one limb can occur as well as abnormalities in the sense of equilibrium. In this case, rapid diagnosis and treatment are essential because symptoms do not improve over time and are likely to worsen.
A detailed examination is needed to accurately distinguish the cause of dizziness.
Manager Lee Min-young said, `Rather than simply dismissing it as anemia or fatigue, we should clearly identify the cause through brain MRI or vestibular function tests." MRI tests are useful for diagnosing central diseases such as stroke and tumor by closely checking the condition of brain tissue and blood vessels. In addition, vestibular functional tests that observe eye movement help distinguish the causes of peripheral dizziness.
Along with this, attention should be paid to orthostatic dizziness caused by autonomic nervous system abnormalities. When you stand up suddenly, your blood pressure drops or your pulse changes rapidly, the blood flow to your brain temporarily decreases, which can lead to dizziness. By measuring changes in blood pressure and heart rate through autonomic neurological tests, the cause can be identified.
Dizziness in daily life is often a temporary phenomenon, but if it is repeated or lasts more than 48 hours, you must seek medical attention. If you have numbness in your limbs, speech disorders, or headaches, you should not wait any longer and visit a hospital.
Manager Lee Min-young said, `Awkwardness is not just a symptom of fatigue, but a sign of an abnormality in the body's balance system"If you find the exact cause early and treat it appropriately, you can expect a good prognosis in most cases," he advised.
