Stroke occurs when poor blood flow to the brain results in cell death. It is the no.5 cause of death in the USA and the leading cause of disability. There are 2 types of stroke: ischemic, which is caused by narrowing or blockage in the arteries leading to the brain, and hemorrhagic, which is caused by reduced blood flow.
When a blood vessel that carries nutrients to the brain is blocked or ruptured by a clot, part of the brain can’t get blood and oxygen it needs to function which leads to cell death. The brain is a complex organ that controls many functions in the body, so when a stroke occurs and there’s reduced blood flow to a certain part of the brain, part or parts of the body that the affected part of the brain controls can’t function properly.
Identifying the symptoms of stroke is of vital importance in order to prevent the condition or get medical help on time to minimize the damage to the brain. This will lower the risk of disability as well. According to experts, the symptoms of stroke vary from person to person and depend on the type of stroke, the part of the brain affected and the severity of the damage.
