Types of Ischemic Stroke?

Ischemic stroke is caused by an obstruction in one of the blood vessels in the brain. There are two types of this classification of stroke, and two types of conditions that are similar to this type of stroke.

As mentioned above, ischemic stroke is caused by a blockage in one of the blood vessels leading to the brain. This blockage is generally a blood clot, and is further identified by where the blood clot develops in the body. When the blood clot develops at the site of an obstruction caused by atherosclerosis, the fatty deposits that can develop along the walls of blood vessels, this is called cerebral thrombosis. When the blood clot develops elsewhere in the body and breaks loose, it travels through the blood stream until it reaches blood vessels too narrow to pass. This is referred to as cerebral embolism.

Cerebral thrombosis is also referred to as thrombotic stroke. The underlying condition for this type of ischemic stroke is typically atherosclerosis and its build up of fatty deposits along the walls of the blood vessels. This causes blood vessels to become narrow and restricted. This can severely restrict blood flow to an area of the body. Blood clots can begin to form along these deposits. This type of blood clot is known as a thrombus. If the blood clot develops enough to completely cut off the flow of blood through the affected blood vessel, this results in a cerebral thrombosis, or thrombotic stroke.

Cerebral Embolism is also referred to as embolic stroke. When a blood clot, or embolus, forms in another part of the body then breaks loose and travels to the brain, this is an embolic stroke. This type of stroke often occurs due to heart disease or heart surgery. There is little or no warning before this happens, as the blood clots, or parts of these clots, breaks loose. These pieces of blood clot travel through blood vessels into the brain until they reach blood vessels that are too small to pass through, where they become lodged and block blood flow. This results in a stroke.Types of Ischemic Stroke?

Two conditions that are similar to stroke and very frequently lead to stroke are silent cerebral infarction, and transient ischemic attack. These both can be considered types of smaller stroke as they block blood flow, though depending on which condition is involved, blood flow is blocked to a very small area, or blood flow is blocked for a short amount of time.

Silent cerebral infarction is also referred to as silent stroke or lacunar infarction. Blood flow is blocked in very small arterial vessels, leading to damage of a small area of the brain. Over time, this leaves the presence of a small hole or empty area of the brain. This silent stroke can occur in many areas of the brain, leading to brain damage or a full scale stroke.

Transient ischemic attack is often referred to as a mini stroke, as a temporary blood clot stops blood flow in the brain for a short period of time. These mini strokes should be a cause for concern, as they are precursors for a full blown stroke.
