• Headache, which can suddenly and unusually severe (sometimes called thunderclap headaches).
• Pain in the face or eyes.
• Double Vision.
• Loss of vision around.
Alarm can occur minutes to weeks before rupture. People should report any unusual headache doctor immediately. Rupture can occur as a sudden, severe headache that culminated in a matter of seconds. This is often followed by a brief loss of consciousness. Nearly half of those affected die before reaching the hospital. Some people remain in a coma or unconscious. The others woke up, felt dizzy and sleepy. They may feel anxious. In a matter of hours or even minutes, people can again become drowsy and confused. They do not react and can be difficult to get up.
Within 24 hours, the blood and cerebrospinal fluid surrounding the brain injured tissue layer which protects the brain (meninges), cause a stiff neck as ongoing headaches, frequent vomiting, dizziness, and pain in the lower back. Frequency up and down the heart rate and breathing are common, sometimes accompanied by seizures are increasing.
In addition, subarachnoid hemorrhage can also causes some serious problems:
1. Hydrocephalus: within 24 hours. Blood of subarachnoid hemorrhage can clot. The blood clot can prevent the fluid around the brain (cerebrospinal fluid) of drought as normal. As a result, an accumulation of blood in the brain, increased pressure in the skull. Hydrocephalus can cause symptoms such as headache, drowsiness, dizziness, nausea, and vomiting, and can increase the risk of coma and death.
2. Vasospasm: about 3 to 10 days after the hemorrhage, the arteries in the brain could be a contraction (spasm), restricting blood flow to the brain. Then, the brain tissue can not get enough oxygen and can die, such as ischemic stroke. Vasopasm can cause symptoms similar to ischemic stroke, such as weakness or loss of feeling in one part of the body, difficulty using or understanding language, vertigo, and weak coordination.
3. The second fraction: two fractions sometimes happens, usually within a week.
