Stroke Treatments And Therapies

The brain is a powerful machine. It is also the most important part after the heart. The brain requires constant pumping of glucose and oxygen from the bloodstream. A cerebrovascular accident also known as a stroke, occurs when blood supply to a part of the brain stops. This results in the death of brain cells. There are numerous ways a stroke may occur. Some of these ways are listed as below:

Artery Block

The small arteries that narrow down within the brain causes a lacunar stroke. The blockage of a single tissue affects a tiny area of brain which causes the tissue to die.

There are several vessels which carry blood to the brain. One of them are the arteries. If the arteries responsible for carrying the blood to the brain, harden this may cause a stroke. There are two important components in the arteries- the anterior circulation which controls sensations, motor activity, speech, thought and emotion is in the cartoid arteries. Whereas posterior circulation is chiefly for the areas cerebellum and the brainstem which are controlled by vertebrobasilar arteries. If these are damaged in any way, they may cause a stroke too

Embolism- In extreme cases, blood clots form within the heart and there are million chances for them to break off and block arteries.

There are other causes that might cause a stroke. It is important to know the kind of stroke one has suffered from, so that it is easy to provide the appropriate stroke treatment. For instance, a stroke can be caused by celebral haemorrhage. This is caused when a blood vessel in the brain ruptures and bleeds into the brain tissues, adjacent to them. This results in loss of blood and oxygen to various parts of the brain.Then there is subarachnoid haemorrhage, in which, the blood acumulates beneath the arachnoid membrane. The symptoms are usually nausea, vomiting, severe headaches and a stiff neck. If not offered the proper stroke treatment this may result in the death of a patient or coma. The third form is a rare condition which is known as vasculitis which results in the inflammation of brain tissues causing them to reduce the blood supply to the brain.

There are different symptoms that show which part of the brain has been affected and which brain tissues have been affected. Once these symptoms manifest themselves, it is recommended to provide the corresponding stroke treatment as soon as possible! There are different treatments available. It is a disorders which requires immediate attention so do the following in case of a stroke:

Calling the emergency number 911. This is the number for the emergency medical transport.

Treatment for acute stroke must be given as soon as possible, since it is a fatal disease

In case somebody is having a stroke, refrain from waiting to see if the symptoms go away.

Do not call the General Physician

Aspirin does not so help. It may be injected later, if needed.

Alternative Stroke Treatment

A stroke is medically refered to as an acute medical emergency otherswise known as a “Brain Attack” which affects the body’s blood circulation. This disruption happens due to a blockage of the system’s blood vessels. This causes a decrease in the level of blood oxygen that travels to the brain as a result a person may encounter severe brain damage, disability and sometimes even death.

There are two kinds of treatment for stroke, that of an ischemic stroke and one used for a hemorrhagic stroke. After getting a stroke, the treatment should be given immediately or within hours following the stroke. When treating ischemic stroke a medical professional should aim to stabilize the patient’s vital signs by giving the patient medicines to stop blood from clotting The healing of hemorrhagic stroke aims to slow down bleeding and minimize swelling in the head. Normally when a doctor takes care of a patient for stroke they need to be notified of how long ago the symptoms occurred.  They need to secure that internal bleeding doesn’t take place as this can cause medical stroke treatments can worsen bleeding. It would be protocol for a scan to be performed on the brain in order to find out the type of stroke and the severity of the injury.

Ischemic stroke can be dealt with by TPA treatment which involves using a needle to isert Tissue Plasminogen Activator (TPA) into the blood vessel. The TPA the goes through the blood stream until it arrives at the build up of blood which caused the stroke. The TPA then dissolves the clot until the blood can flow past it towards the affected areas. Note that TPA should not be given to an individual who go to the emergency room three hours after going through a stroke because at this point the TPA doesn’t work to treat the stroke and at this point it can increase the risk of bleeding in the brain.

The Mechanical Embolus Retrieval in Cerebral Ischemia (MERCI Retriever) is a newly introduced method of taking care of stroke patients but it is still in its experimental phase. This method of treatment uses a device which is placed into a blood vessel in the leg that travels up to a blood vessel in the head where the blood clot happens. The retriever then locates the clot and removes it from the head and returns the blood flow back to normal. The only problem with this method is that there are not many equipments and specialists who are able to utilize this technology; however, it has achieved miraculous results so far.

Another form of stroke treatment is Intra-Arterial Thrombolysis which is given depending on the location of the stroke on the brain. However this form of treatment is normally only available at few hospitals because it calls for expertise and . This treatment can be provided within another 6 hours after the stroke occurs, it involves injecting the TPA and then putting in a special small catheter into a one of the main blood vessel in the leg. The catheter would be strategically moved up towards the brain with the aid of a special video camera. When the blood clot is found, the small catheter is then sent into its center at the location of the injection. The TPA then begins to break up the rupture until the blood is able to flow past the clot towards the location of stroke, thus relieving the area.
