Brain accidents
Each area of our brain controls a neurological function. The function of the region affected by the brain accident is lost or diminished to a greater or lesser degree. A brain accident, also called "stroke", is a disease caused by alterations in the blood vessels that irrigate the brain.
This malignant causes neurological symptoms and they occur suddenly. The nerve cells (neurons) do not have the ability to reproduce and are also unable to store the food that reaches them through the blood. If there is a problem in the vessels and the blood supply decreases abruptly, the neurons in the affected area begin to die. When the injured region is speech, for example, that function will be lost or decreased. The blood reaches our brain through the carotid arteries, climbing up the sides of the neck, and vertebral, traversing the cervical vertebrae.
Thrombosis, embolism and hemorrhages
The cerebral arteries are sensitive to the formation of plaques of atheroma, cholesterol or other substances. If one of them breaks, a thrombus or clot forms that blocks the blood vessel. A thrombus formed, usually in the heart, gets stuck in an artery of the brain and forms the embolism. The hemorrhages originate when a cerebral vessel breaks down and bleeds inside the skull and exerts pressure on other nervous structures.
Risk factors to take care of
The most important risk factors for a brain accident to occur and that we all have to take into account when taking care of our health are smoking , hypertension , high blood cholesterol level , diabetes , age very advanced and cardiac injuries .
