One of the symptoms of cerebrovascular accident (CVA) - a disease that kills more in Brazil, according to a survey by the Ministry of Health - is the Headache. Often, a simple migraine is confused with signs of a brain aneurysm, and relief is not provided properly, at the right time.

Differentiating stroke and headache aneurysm
Dr. Sergio Tadeu Fernandes, the Integrated Brazilian Institute of Neuroscience (iBrain) clarifies that, before anything, you need to identify the two types of headache: a Primary headache and the Secondary headache.
"Primary occurs when the headache can be defined as the problem itself. Pain is a disease, it is not a symptom. For example, migraine is just a migraine and, in most cases, does not reveal a more serious problem"Says the doctor.
Already the secondary occurs when the headache is a symptom of some other disease, usually more critical and risk of sequelae or death. "In case, some types of stroke may have a headache as a symptom. In this case, it is secondary, and it is to her that we must be vigilant in the cases of stroke".
severe headache: is stroke?
Not every stroke is manifested by headaches, says Sergio. But in some cases, the pain may indeed be Stroke symptom. The doctor explains that there are two fundamental characteristics that make worrying headache.
ThinkstockA stroke characteristic headache has two particularities
The first is the early rising. The pain is very sharp, very strong, and starts suddenly and already in its greatest intensity. "It is an atypical pain, which is usually not always feel with those precise characteristics"Specifies the neurosurgeon.
The second feature is the headache changing pattern. Suppose, for example, you are already "used" with a certain type of migraine, a throbbing pain that starts low and increases. And what a particular type of analgesic usually work for you to combat this discomfort. "One should be attentive to any change in the pattern of pain. If it starts to come more often or intensity if the medicine that worked before does not help more, or if the pain to appear at some point it used to appear: all this is a warning sign and asks for a trip to the emergency room"Is recommended.
Sometimes the headache is accompanied by Classic symptoms of stroke: Behavior changes, drowsiness, paralysis on one side of the body or face, fainting, loss of the ability of speech, among others. In such cases, even if there is headache, you should immediately go to hospital.
Aneurysm, ischemic stroke and hemorrhagic stroke
Neurosurgeon clarifies the differences between the problems and alert: "Stroke most often confused with primary headache is haemorrhagic".
- aneurysm: It is an abnormal dilation of a blood vessel in the brain. "It is like a weak point. I usually compare it to a plumbing that does not work. Only one realizes that there is a defective pipe to start an infiltration or it burst. It's the same in the brain: the aneurysm is discovered, usually when suffering a type of stroke"Says Sergio.
ThinkstockO stroke that gives more headache is the hemorrhagic
- Stroke or stroke: It is a consequence of the aneurysm, and can be of two types.
- Hemorrhagic stroke: It occurs when the rupture of the aneurysm, bleeding.
- Ischemic Stroke: the cerebral vessel clogs, the blood does not circulate properly and the affected area ends up suffering a stroke - it ceases to be irrigated and causes sequelae. It is the most common type of stroke (about 80% of cases), according to Sergio.
The doctor says there is no most serious type of stroke: Both are equally dangerous in terms of risk of death and sequelae depending on the extent of the area of the brain is compromised. Moreover, there is no difference between the symptoms of each of the two. "You can only differentiate later, in very specific tests, such as CT or MRI".
Action Time in Stroke: crucial to save lives and prevent or reduce sequelae
According to Sergio, the most important thing is to act quickly if any of the symptoms appear, including pain secondary head with both worrisome characteristics (sudden and out of the usual pattern).
"Time is essential: the faster the rescue and diagnosis, the more likely to minimize or even eliminate 100% the consequences", Says the neurosurgeon.
ThinkstockO most appropriate is to treat the patient in the hospital
And what's that time of action? "Six hours after the demonstration of the first stroke symptoms"Says Sergio. "If the patient arrived at the hospital six hours after the first moment of these changes, it is possible to treat stroke and dissolve the picture. Outside of that, can you minimize complications, but the chance to go to death or get permanent damage is very large".
One feature, however, is when the person goes to sleep and wake up with symptoms. In this case, one must take into consideration the last time the patient was seen without abnormalities.
Why stroke kills both?
The disease victim one person every five minutes in Brazil, according to a study by the Ministry of Health. And the reason for this, according to Sergio, is that most people underestimate the symptoms of stroke. "It is an extremely critical situation: we are talking about death, speech impairment, movement, coma, serious consequences and may be permanent"Says the neurosurgeon. So run to the doctor if you suspect something may be crucial in treating the disease.
of stroke risk groups
ThinkstockConsumidores of alcoholic beverages and smoking are among those who are more likely to have a stroke
In general, they are the same for the heart attack. "Stroke is a disease of the vessels that manifests in the brain. So, all body vessels are committed"Clarifies the professional.
People with high blood pressure, sedentary, smoking, diabetes, alcohol and drug users are some who are more likely to have stroke. Stress is another risk factor.
How to treat stroke?
In people with more chances of developing the disease, it is the medical follow-up more closely. "There are some tests that identify the disease in its early stages. We can make use of a treatment with drugs to thin the blood, before the problem compromises the cerebral oxygenation"Says Sergio. In some cases, you can do a surgical procedure to treat stroke.
