Blood Supply to the Brain

A stroke is a blockage or rupture of a blood vessel in the brain that suddenly interrupts or reduces the blood supply to the brain. The brain then cannot receive enough oxygen or nutrients, and brain cells begin to damage. This condition occurs when the blood supply to the brain is interrupted or reduced due to a blockage (ischemic stroke) or rupture of a blood vessel (hemorrhagic stroke). Without blood, the brain will not get oxygen and nutrients, so cells in some areas of the brain will die. Stroke can be proven by imaging or pathological examination, and can result in permanent disability or death if not treated immediately. Other data, the neurologist continued, this disease is also the number one cause of disability, both in the world and in Indonesia. All types of stroke are basically dangerous, but there are several types of which cause severe disability and or lead to death. Stroke is generally divided into two types, namely ischemic stroke and hemorrhagic stroke. Although classified as a disease that can be life threatening, stroke patients can still recover completely. The key is to get treatment as soon as possible after the initial symptoms occur. Because the golden period for stroke treatment is during the first 4.5 hours after the initial symptoms appear.
