What is brain ischemia?

All organs in the body, especially in the brain, rely on a reasonable supply of oxygenated blood. However, there are certain conditions and diseases that result in the loss of blood flow to the brain and starvation of oxygen and glucose. This loss of blood flow is called cerebral ischemia.

The most common cause of brain ischemia is stroke. Mency is a focal neurological deficit that occurs when blood vessels supplying blood become either blocked or bleeding, causing either an occlusive stroke or a hemorrhagic stroke. Okluzive strokes occur due to thrombus or clot of blood in blood vessels supplying blood to the brain, while hemorrhagic strokes are generally the result of ongoing high blood pressure. As soon as the supply of oxygenated blood has been reduced to the brain, the short loss of consciousness of consciousness, called syncope, may also occur. Lack of oxygen to the brain due to brain ischemia is called hypoxia. Hypoxia can permanently destroy neurons by a process called necrosis, which can lead tobrain damage. The death of necrotic cells happens when the cell membrane is quickly destroyed and during the autopsy the cell membrane seems softer in the texture.

There may be two different types of brain ischemia for stroke: focal brain ischemia and global ischemia. Individual suffering focal brain ischemia will still have a certain degree of circulation into parts of the brain; However, a patient with global ischemia will not have blood flow to any area of ​​the brain. A transient ischemic attack (TIA) is a term applied to ischemic symptoms that are focal and last for a short time. These attacks can prevent moves, but may also occur separately and are generally the result of vascular diseases such as atherotrbose. Recognition and treatment of TIA soon is very important because the patient may be endangered by a cerebral infarction or stroke in the future.

There are many different drugs prescribed to patients suffering from TIa. One such treatment is aspirin, which is effective in preventing embolic and thrombotic strokes. Aspirin works by reducing and preventing the aggregation of plates. If patients are unable to tolerate this medicine, the clopidogrel inhibitor inhibitor inserts or other similar drugs is also effective.
