What is brain ischemia?
brain ischemia is an interruption of blood supply to the brain and disrupts the flow of oxygen and nutrients needed to maintain the functioning of the brain cells. Depending on the location of the ischemia, the extent and how long it takes, the patient could develop damage and threaten death. Many things can cause brain ischemia, including strokes, trauma into the brain and abnormalities of blood vessels. Neurologists usually participate in treatment and the patient may need medicines, surgery or other interventions. Freshly oxygenated blood travels on carotid arteries to the head and neck and provides a stable blood supply to the brain. Even short interruptions can cause brain ischemia and potentially lead to a situation called ischemic cascade, where brain cells with insufficient blood supply begin to die and release toxins that damage non -nighand cells that cause to tear and release their own toxins.
Most often, brain ischemia includes carotid artery, but one of the smaller blood vessels in the brain. Blood vessels can develop clots, prevent blood flow and cause stroke. They can also burst, or the patient can develop vascular malformations where the blood vessels grow abnormally and cannot get blood to where they have to go. Heavy trauma of the head can also lead to ischemia by tearing or crushing blood vessels to prevent blood in some areas of the brain.
The symptoms of brain ischemia vary depending on the brain area. Things such as unfortunate speech, confusion, changes in vision and stiffness, as well as muscle control, are common. The beginning of symptoms can be very fast. If a quick treatment is provided, there is a chance recovery. Other patients may have brain damage and may need therapy to re -take place some skills. In some cases, damage cannot be addressed by therapy and the patient will have permanent damage as limp.
when brain ischeMIE includes areas of the brain responsible for regulating functions such as breathing, heart rate and metabolism, this can lead to a coma, persisting vegetative state or death. The brain stem cannot recover from severe damage. Milder brain damage may result in damage requiring that the patient uses a breathing fan.
