The anatomy of the brain is complex due its intricate structure and function. Thisamazing organ acts as a control center by receiving, interpreting, and directing sensoryinformation throughout the body. There are three major divisions of the brain. They arethe forebrain, the midbrain, and the hindbrain.

Anatomy of the Brain: Brain Divisions

The forebrain is responsible for a variety of functions including receiving andprocessing sensory information, thinking, perceiving, producing and understandinglanguage, and controlling motor function. There are two major divisions of forebrain: thediencephalon and the telencephalon. The diencephalon contains structures such as thethalamus and

There are many other nervous system disorders that can mimic a stroke including a brain tumor, a subdural hematoma (a collection of blood between the brain and the skull) or a brain abscess (a pool of pus in the brain caused by bacteria or a fungus). Virus infection of the brain (viral encephalitis) can cause symptoms similar to those of a stroke, as can an overdose of certain medications. Dehydration or an imbalance of sodium, calcium, or glucose can cause neurologic abnormalities similar to a stroke.
Treatment of a stroke: Early use of anticoagulants to minimize blood clotting has value in some patients. Treatment of blood pressure that is too high or too low may be necessary. (Lowering elevated blood pressure into the normal range is no longer recommended during the first few days following a stroke since this may further reduce blood flow through narrowed arteries and make the stroke worse.) The blood sugar glucose in diabetics is often quite high after a stroke; controlling the glucose level may minimize the size of a stroke. Drugs that can dissolve blood clots may be useful in stroke treatment. Oxygen is given as needed. New medications that can help oxygen-starved brain cells survive while circulation is reestablished are being developed.
Rehabilitation: When a patient is no longer acutely ill after a stroke, the aim turns to maximizing the patient's functional abilities. This can be done in an inpatient
