What is the term for the death of brain cells?
Cortical Laminar Necrosis. Cortical laminar necrosis involves the death of brain cells that is usually caused by reduced blood flow to the brain, otherwise known as ischemia. Brain cells require a lot of blood to function properly and survive because the blood provides the cells of the brain with oxygen and nutrients.
Why do brain cells need blood?
Brain cells require a lot of blood to function properly and survive because the blood provides the cells of the brain with oxygen and nutrients. If the blood flow to the brain is reduced, the cells of the brain may not receive enough oxygen and nutrients, possibly resulting in the destruction and death of the cells.
Why do strokes occur?
This can occur because of an obstruction such as a blood clot or plaque build-up that prevents blood flow. Strokes can also be the result of an aneurysm which occurs when the blood vessels to the brain burst, which prevents the blood from reaching parts of the brain. Strokes can cause reduced blood flow to the brain.
What causes a stroke to be reduced?

Pathophysiology
The exact pathologic mechanism for RCN is unclear, however the onset of small vessel pathology is likely an important aspect in the cause of this condition.
Diagnosis
While the only diagnostic "gold standard" mechanism of diagnosis en vivo is via kidney biopsy, the clinical conditions and blood clotting disorder often associated with this disease may make it impractical in a clinical setting. Alternatively, it is diagnosed clinically, or at autopsy, with some authors suggesting diagnosis by contrast enhanced CT.
Treatment
Patients will require dialysis to compensate for the function of their kidneys.
