Ataque cerebral

Aprender lo que es un AIT, como es un signo serio de advertencia de un ataque cerebral y la importancia de llamar al 911 si alguien está mostrando los signos de tener un AIT.

Un ataque isquémico transitorio o AIT, a veces se conoce como un "mini accidente cerebrovascular". Esto ocurre cuando se interrumpe el suministro de sangre al cerebro durante un período muy corto de tiempo. El AIT es una afección grave y no debe ignorarse. Este video muestra lo que debe tener en cuenta y por qué debe buscar tratamiento de inmediato.

Con este video aprenderás sobre los tres distintos tipos de ataques cerebrales.

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

Existen factores de riesgo que pueden terminar en un ataque cerebral que puede controlar y otros que no puede controlar. Aprenda cuáles puede cambiar o tratar y cuáles factores de riesgo están fuera de su control. © 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.

A stroke requires immediate medical attention. Know the signs of stroke.

Eating healthy foods helps lower cholesterol levels and reduce plaque buildup in arteries. It can also help you lose weight and keep high blood pressure under control.

Breaking old habits can be hard. But when your health is at stake, it's never too late to make changes for the better. Some lifestyle changes might be easy for you. Others might be tough.

A subdural hematoma is a buildup of blood on the surface of the brain. The blood builds up in a space between the layers that surround your brain.

A carotid dissection is a tear in the inner layer of an artery in the neck. You have one carotid artery on each side of your neck. These arteries send blood to your brain.

This test makes X-ray images of blood vessels in your brain. It is used to help your doctor find problems with those blood vessels.

Carotid artery disease causes a narrowing of the major blood vessels that supply the brain. It is caused by atherosclerosis and can lead to a stroke.

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.
