The pain of these severe headaches peaks within 60 seconds.<\/p>\n<p>Thunderclap headaches are uncommon, but they can warn of potentially life-threatening conditions &mdash; usually having to do with bleeding in and around the brain. Seek emergency medical attention for a thunderclap headache.<\/p>\n<p>Thunderclap headaches are dramatic. Symptoms include pain that:<\/p>\n<ul>\n<li>Strikes suddenly and severely<\/li>\n<li>Peaks within 60 seconds<\/li>\n<li>Can be accompanied by nausea or vomiting<\/li>\n<\/ul>\n<p>Thunderclap headaches might be accompanied by other signs and symptoms, such as:<\/p>\n<ul>\n<li>Altered mental state<\/li>\n<li>\u71b1<\/li>\n<li>\u767a\u4f5c<\/li>\n<\/ul>\n<p>These signs and symptoms might reflect the underlying cause.<\/p>\n<h3>When to see a doctor<\/h3>\n<p>Seek immediate medical attention for any headache that comes on suddenly and severely.<\/p>\n<p>There&#8217;s no obvious cause for some thunderclap headaches. In other cases, a variety of potentially life-threatening conditions might be responsible, including:<\/p>\n<ul>\n<li>Bleeding between the brain and membranes covering the brain (subarachnoid hemorrhage)<\/li>\n<li>A rupture of a blood vessel in the brain<\/li>\n<li>A tear in the lining of an artery that supplies blood to the brain<\/li>\n<li>Leaking of cerebrospinal fluid &mdash; usually due to a tear of the covering around a nerve root in the spine<\/li>\n<li>Death of tissue or bleeding in the pituitary gland<\/li>\n<li>A blood clot in the brain<\/li>\n<li>Severe elevation in blood pressure (hypertensive crisis)<\/li>\n<li>Infection such as meningitis or encephalitis<\/li>\n<li>Ischemic stroke<\/li>\n<\/ul>\n<p>The following tests are commonly used to try to determine the cause of a thunderclap headache.<\/p>\n<ul>\n<li><strong><abbr title=\"computed tomography\">CT<\/abbr> scan of the head.<\/strong> <abbr title=\"computed tomography\">CT<\/abbr> scans take X-rays that create slice-like, cross-sectional images of your brain and head. A computer combines these images to create a full picture of your brain. Sometimes an iodine-based dye is used to augment the picture.<\/li>\n<li><strong>Spinal tap (lumbar puncture).<\/strong> The doctor removes a small amount of the fluid that surrounds your brain and spinal cord. The cerebrospinal fluid sample can be tested for signs of bleeding or infection.<\/li>\n<li><strong><abbr title=\"magnetic resonance imaging\">MRI<\/abbr>.<\/strong> In some cases, this imaging study might be done for further assessment. A magnetic field and radio waves are used to create cross-sectional images of the structures within your brain.<\/li>\n<li><strong>Magnetic resonance angiography.<\/strong> <abbr title=\"magnetic resonance imaging\">MRI<\/abbr> machines can be used to map the blood flow inside your brain in a test called a magnetic resonance angiography (MRA).<\/li>\n<\/ul>\n<p>Treatment is aimed at the cause of the headaches &mdash; if one can be found.<\/p>\n<p>Thunderclap headaches are often diagnosed in an emergency room. However, if you call to set up an appointment with your own doctor, you might be referred immediately to a doctor who specializes in the brain and nervous system (neurologist).<\/p>\n<p>If you have time to prepare for your appointment, here&#8217;s some information to help you get ready.<\/p>\n<h3>What you can do<\/h3>\n<p>Make a list of:<\/p>\n<ul>\n<li><strong>Your symptoms,<\/strong> including any that may seem unrelated to your headaches, and when they began<\/li>\n<li><strong>Key personal information,<\/strong> including major stresses, recent life changes and medical history<\/li>\n<li><strong>All medications,<\/strong> vitamins and other supplements you take, including doses<\/li>\n<li><strong>Questions to ask<\/strong> \u3042\u306a\u305f\u306e\u533b\u8005<\/li>\n<\/ul>\n<p>Take a family member or friend along, if possible, to help you remember the information you receive.<\/p>\n<p>Some questions to ask your doctor include:<\/p>\n<ul>\n<li>What is likely causing my headaches?<\/li>\n<li>Are there other possible causes for my headaches?<\/li>\n<li>What tests do I need?<\/li>\n<li>Is my condition likely temporary or chronic?<\/li>\n<li>What is the best course of action?<\/li>\n<li>I have these other health conditions.
