In a study published today in the Journal of Experimental Medicine, researchers successfully used a new approach that significantly minimized brain damage caused by stroke in mouse models. Stroke-induced brain injury results in permanent damage, so the best treatment to prevent the occurrence or the reoccurrence of stroke is to reduce the risk factors that cause stroke, including high blood pressure, heart disease, diabetes, high cholesterol, and smoking. The most common types of brain scans used are computerised tomography (CT) and magnetic resonance imaging (MRI) scans. Discover the symptoms, causes, and risk factors of ischemic stroke. In a new study of patients with the heart rhythm disorder atrial fibrillation (a-fib), 4 in 10 had previously undetected brain damage, though none had a history of stroke or mini-stroke. Brain scans - these can help with confirming diagnosis of the type of stroke that has occurred and also whereabouts in the brain it has taken place.

The way a stroke affects the brain depends on which part of the brain suffers damage, and to what degree. When a stroke occurs, part of the brain becomes damaged and a chunk of these connections are destroyed. Once brain tissue has died, the body parts controlled by that area won’t work right.

This triggers the many physical and mental changes in stroke victims. When a stroke causes a blood vessel to block or rupture, the neurons in the brain are deprived of blood. This can help with guiding treatment at the next stage. A stroke occurs when blood supply to the brain is interrupted. It's also referred to as brain ischemia and cerebral ischemia. When nerve cells are damaged, they starve and die since blood can't reach the regions that control bodily functions. Without oxygen, brain cells begin dying within minutes. When your brain tries to heal itself, functions that were once held in damaged parts of the brain are then transferred to new, healthy parts of the brain.

A stroke occurs when blood supply to the brain is interrupted. Ischemic stroke is the most common of the three types of stroke. Brain damage occurs when a person’s brain is injured due to traumatic injury, such as a fall or car accident, or nontraumatic injury, such as a stroke. The way a stroke affects the brain depends on which part of the brain suffers damage, and to what degree. But that’s where neuroplasticity comes into play. Simply defined, aphasia is the loss of ability to communicate normally resulting from damage, typically to the left side of the brain, which houses the communication center. Stay safe and healthy. Researchers claim cooling the brain may prevent further damage to stroke victims.
