RELATED TERMS--------------------------------------
Stroke
A stroke, or a Cerebrovascular Accident, occurs when blood vessels that deliver oxygen to the brain, either rupture or become clogged, causing brain/nerve cells to die. Results are usually devastating as nerve/brain cells are not replaced. Usually characterized by a slurring of words, weakness on one side of the body, and a drooping facial expression on one side of the face.
Intracerebral
Located within the cerebral hemispheres (cerebrum). See extracerebral.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Brain
"That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called ""hemispheres."" "
Aneurysm
A weakness in the blood vessel wall that balloons out and may rupture at some point. Aneurysms rarely cause symptoms before the rupture, unless they are large. They do not mimic the symptoms of migraine or cluster headache. It is vital to discover them before they rupture and have catastrophic consequences such as paralysis or death.
