[Asia Economy Reporter Lee Gwan-joo] When experiencing headaches or dizziness, people often want to undergo magnetic resonance imaging (MRI) scans. However, medical institutions typically perform MRI scans covered by insurance only when brain disease is suspected.

The problem is that headaches are such a common symptom that it is difficult for the general public to determine whether they are caused by a serious condition or not. A severe headache does not necessarily indicate a serious brain disease, nor can a mild headache be definitively ruled out as unrelated to brain disease. Most headaches are simple, but they can also be caused by warning signs of stroke or brain tumors.

Therefore, it is necessary to first recognize headaches and accompanying symptoms that strongly suggest brain disease. Neurologist Cho So-young of H Plus Yangji Hospital explained, "Headaches that strongly suggest brain disease are those accompanied by other neurological symptoms, such as unilateral paralysis, double vision, visual field abnormalities, speech difficulties, nausea, vomiting, and severe balance disorders with dizziness occurring alongside headaches, which should raise suspicion of brain disease."

If a sudden severe headache persists or worsens with coughing, straining, or sexual activity, cerebrovascular examination is necessary. Patients with this type of headache undergo vascular MRI, and brain vascular CT can also be a very effective test. If symptoms of headache suggestive of brain disease appear or if new headaches develop and progressively worsen after middle age, it is important to find the cause through consultation and examination by a specialist.

Dr. Cho emphasized, "Simple headaches do not meet the criteria for MRI insurance coverage, and an MRI scan does not always reveal the cause of a headache, nor does it improve the headache itself," adding, "It is important to receive an accurate diagnosis through specialist consultation and examination rather than self-treatment."

Since early detection of brain disease is difficult, it is advisable to prevent it in advance through annual health checkups. To prevent and manage headaches, stress management is crucial. Light aerobic exercise at least three times a week can supply blood to the brain and have beneficial effects, while limiting caffeinated beverages, maintaining regular meals, and consuming nutrient-rich foods with high water content such as fruits and vegetables are helpful.
