Is it ischemic or hemorrhagic

Early treatment of ischemic stroke 

Ischemic stroke happens when a blood clot blocks a vessel supplying blood to the brain. It’s the most common type, accounting for 87% of all strokes. The treatment goal is to dissolve or remove the clot. To dissolve a clot, a medicine called alteplase (tPA) is given through an IV (intravenous line). It works by dissolving the clot so blood can flow again. Alteplase can save lives and reduce the long-term effects of stroke. It needs to be given within three hours of the start of stroke symptoms (up to 4.5 hours for some eligible patients). To remove a clot involves a procedure called mechanical thrombectomy. Doctors use a wire-cage device called a stent retriever to remove a large blood clot. They thread a catheter through an artery in the groin up to the blocked artery in the brain. The stent opens and grabs the clot, allowing doctors to remove the stent with the trapped clot. Special suction tubes may also be used to remove the clot. This procedure must be done within up to six to 24 hours of stroke symptom onset and after the patient has received alteplase, if eligible. Patients must meet certain criteria to be eligible for this procedure.

 Early treatment of hemorrhagic stroke 

Hemorrhagic stroke happens when a blood vessel bursts (ruptures) and bleeds within or around the brain. Blood vessels can become weak due to a ballooning of part of the vessel (aneurysm). Other times there may be a tangle of blood vessels within the brain that didn’t form normally, making them weak (arteriovenous malformation or AVM). When high blood pressure isn’t controlled, it puts strain on weakened blood vessels that can lead to the ruptures that cause stroke. The treatment goal is to stop the bleeding. For some patients, a small tube (catheter) with a camera is threaded through a major artery in an arm or leg and guided to the area of the bleed in the brain. The camera gives the surgeon a detailed view of the area to help fix the problem. Once the catheter is guided to the source of the bleeding, it leaves a mechanism, such as a coil, to prevent further rupture. This type of procedure is less invasive than standard surgical treatment. Sometimes surgery is required to secure a blood vessel at the base of the aneurysm.
At United Stroke Alliance we urge you to Be-Faster!
If you have detected the following stroke symptoms, don't wait.  


Don't wait, be Be-Faster to save someone's life. Awareness is critical! What if you could help save your life or someone else’s by knowing the signs of stroke? Once a stroke begins to present itself, BE-FASTER and dial 911 immediately - the more time that is wasted, the more functioning you could lose as a result – up to 1,900,000 brain cells a minute or worse - death. Act FAST when stroke strikes. Be aware of the signs of a stroke and how to act:

Sudden loss of balance

Sudden blurry or loss of vision

Sudden numbness, one side drooping - can you smile?

Sudden weakness in arms - can you raise both?

Slurred or mumbling speech


Get to the ER by ambulance they know what to do FASTER!
