In an ischemic stroke, blood supply to part of the brain is decreased, leading to dysfunction of the brain tissue in that area.

An ischemic stroke (cerebral infarction) occurs when a blood vessel that supplies a part of the brain becomes blocked. This loss of blood supply results in the death of brain tissue in that area. Cerebral infarctions vary in their severity with one third of the cases resulting in death.

Diagnosing Ischemic Stroke

Stroke remains a diagnosis based upon clinical exam findings. By understanding deficits that result from brain lesions, a neurologist is capable of localizing a stroke to a specific lobe or hemisphere of the brain. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) scanning are capable of showing damaged area in the brain and rule out other causes of neurologic deficits, i.e. hemorrhage, tumor, subdural hematoma or other brain disorder. Vessel imaging to identify the arterial blockage can be performed with CT Angiography (CTA), MR Angiography (MRA) or conventional angiography by neurointerventionalists.
