Es muy importante diagnosticar el ataque cerebral mientras está ocurriendo, pues el tratamiento del ataque cerebral depende del tipo y, en algunos casos, de la ubicación de la lesión en el cerebro. Para diagnosticar un ataque cerebral, se deben descartar otras condiciones con síntomas similares a los del ataque cerebral y a los del ataque isquémico transitorio (AIT). Algunos de estos síntomas incluyen convulsiones, desmayos, migrañas, sobredosis de drogas, problemas cardíacos u otras afecciones médicas en general. © AHA

Aproximadamente un 13 por ciento de los ataques cerebrales ocurren cuando se rompe un vaso sanguíneo en el cerebro o cerca de éste. A esto se le llama ataque hemorrágico al cerebro. Cuando sucede un ataque hemorrágico al cerebro, la sangre se acumula en el tejido cerebral. Esto es tóxico para el tejido cerebral y hace que las células de esa área se debiliten y mueran.

Hipertensión arterial (HBP) significa que la fuerza de la sangre que empuja contra las paredes de los vasos sanguíneos está constantemente en el rango alto. Unaa HBP no controlada puede provocar un ataque o derrame cerebral, ataque cardíaco, insuficiencia cardíaca o insuficiencia renal. © AHA

La mayoría de los ataques cerebrales ocurre cuando los vasos sanguíneos que llegan al cerebro se estrechan u obstruyen con depósitos grasos llamados placa. Esto reduce el flujo sanguíneo a las células cerebrales. Un ataque cerebral causado por falta de sangre a una parte del cerebro se denomina ataque isquémico al cerebro. La presión arterial alta es uno de los principales factores de riesgo de sufrir un ataque cerebral isquémico. © AHA

A transient ischemic attack (TIA) is often called a mini-stroke, but it's really a warning stroke. TIA and stroke symptoms are the same, although most TIA symptoms last only a few minutes (but up to 24 hours). While TIAs generally do not cause permanent brain damage, they are major warnings and should not be ignored. © AHA

Many strokes may be prevented through blood pressure control, a healthy diet, regular physical activity and smoking cessation. Each plays a big part in decreasing your risk for stroke, disability or even death. © AHA

A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. It can cause permanent disability or even death. Although stroke is the fifth-leading cause of death, Hispanic people in the U.S. face an even higher risk. It's the No. 4 cause of death for Hispanic men and No. 3 for women. © AHA

Stroke — the fifth leading cause of death in America — is a "brain attack" that occurs when blood that brings oxygen to your brain stops flowing and brain cells die. Black Americans have a higher prevalence of stroke and highest death rate from stroke than any other racial group. © AHA

Adults who have diabetes are two times as likely to have a stroke compared to people who do not have diabetes. The connection between diabetes and stroke has to do with the way the body handles blood glucose to make energy. © AHA

Un ataque cerebral ocurre cuando un vaso sanguíneo que lleva sangre y oxígeno al cerebro se obstruye con un coágulo o se rompe. Cuando esto sucede, las neuronas no reciben la sangre y oxígeno que necesitan para sobrevivir. Esto provoca que las neuronas dejen de funcionar y mueran en minutos. Entonces la parte del cuerpo que controlan se ven afectadas. Los efectos del ataque cerebral pueden ser permanentes en función de cuántas células se han perdido, dónde se encuentran en el cerebro y otros factores. © AHA

A hemorrhagic stroke happens when a blood vessel in the brain ruptures or leaks. A blood vessel on the surface of the brain bursts (hemorrhages). This spills blood into the surrounding tissue. This type of stroke often happens suddenly, with little warning.

The earlier treatment for a stroke is started after symptoms begin, the more likely you are to survive and recover. Here is what you can expect during treatment.

Every part of your body, including your heart and your brain, needs oxygen to work. Oxygen is carried in the blood. Blood vessels called arteries carry oxygen-rich blood throughout the body. Both heart attack and stroke are due to problems in the arteries. The same factors that cause heart disease can make you more likely to have a stroke.

This type of stroke can have a wide range of effects in the body and cause a broad range of symptoms.

Most strokes are caused by a blockage in a blood vessel that supplies the brain. They can also occur if a blood vessel in the brain ruptures (bursts open).

A TIA (transient ischemic attack) is an early warning that a stroke (also called a brain attack) is coming. A TIA is a temporary stroke. It causes no lasting damage. But the effects of a stroke, if it happens, can be very serious and lasting. Here are symptoms to watch for.

When the carotid arteries are healthy, the brain gets all the oxygen and nutrients it needs to function well. If the carotid arteries are damaged, however, it can greatly increase your chances of stroke.

The Hunt-Hess scale helps the doctor assess a patient's condition.

Each day that your blood pressure is too high, your chances of having a stroke are increased.

You have an arteriovenous malformation (AVM). An AVM is an abnormal tangle of blood vessels in the brain. Some AVMs never burst (rupture). But there are factors that can lead to rupture. If you have an AVM, you were likely born with it. But most people don't know they have one until a problem happens.

Here you will find out how to prepare for AVM surgery, what to expect the day of surgery, and the risks of surgery.

The brain needs a constant supply of blood to work. During a stroke, blood stops flowing to part of the brain.

Certain health and lifestyle issues - called risk factors - increase your chances of having a stroke. This page helps you identify which risk factors you have.

During a stroke, blood stops flowing to part of the brain. This can damage areas in the brain that control the rest of the body. Get help right away if any of these symptoms come on suddenly, even if the symptoms don't last.

A cerebrovascular accident is a mild stroke. This is caused by a loss of blood flow to part of the brain.

Your symptoms were caused by a TIA, also called a mini-stroke. Even though your symptoms have gone away, this condition is as serious as a full stroke.

It is estimated that 30% (200,000) of ischemic strokes in the U.S. are cryptogenic — meaning the cause is unknown. This video by American Stroke Association explains diagnosis and treatment.

An ischemic stroke occurs when blood flow to the brain is blocked. This is most often due to a blood clot in an artery in the brain or an artery leading to the brain. Treatment is needed right away to help dissolve the clot and restore normal blood flow.

Vertebral artery dissection is the most common causes of stroke in young and middle-aged adults, but it can occur at any age.

After a stroke, a person may feel sudden or extreme emotions. Sadness and depression are common. These feelings may be due to damage in the brain. Or they may be a response to the person's awareness of what has happened.

The treating doctor's highest priorities are to prevent complications that can occur as a result from the stroke and to prevent another stroke. Your doctor must determine that you are medically stable and able to resume some self-care activities. This means that all complications must be treated and under control. Some things happen as a direct result of injury to the brain due to stroke. Others are because of a change in your abilities. For example, being unable to move freely can result in bedsores. Clinical depression can also occur with a stroke. © AHA
