Ischemic Stroke
An Ischemic Stroke ocurrs when a clot or mass clogs a blodd vessel cutting off the blood flow to brain cells.

Embolic Stroke
In an embolic stroke, a blood clot forms somewhere in the body (usually the heart) and travels through the bloodstream to your brain. Once in your brain, the clot eventually travels to a blood vessel small enough to block its passage. The clot lodges there, blocking the blood vessel - causing a stroke. The medical word for this type of blood clot is embolus.
Thrombotic Stroke
Thrombosis strokes are known as blood flow being impaired because of a blockage to one or more of the arteries supplying blood to the brain. Strokes caused in this way are called thrombotic strokes. That's because the medical word for a clot that forms on a blood-vessel deposit is thrombus.
Blood-clot strokes can also happen as the result of unhealthy blood vessels clogged with a buildup of fatty deposits and cholesterol. Your body regards these buildups as multiple, tiny and repeated injuries to the blood vessel wall. So your body reacts to these injuries just as it would if you were bleeding from a wound; it responds by forming clots. Two types of thrombosis can cause stroke: large vessel thrombosis and small vessel disease (or lacunar infarction.)
Large Vessel Thrombosis
Thrombotic stroke occurs most often in the large arteries, so large vessel thrombosis is the most common and best understood type of thrombotic stroke. Most large vessel thrombosis is caused by a combination of long-term atherosclerosis followed by rapid blood clot formation. Thrombotic stroke patients are also likely to have coronary artery disease, and heart attack is a frequent cause of death in patients who have suffered this type of brain attack.
Small Vessel Disease/Lacunar Infarction
Small vessel disease, or lacunar infarction, occurs when blood flow is blocked to a very small arterial vessel. The term's origin is from the Latin word lacuna which means hole, and describes the small cavity remaining after the products of deep infarct have been removed by other cells in the body. Little is known about the causes of small vessel disease, but it is closely linked to hypertension (high blood pressure).
TIA
TIA's are known as Transient Ischemic Attacks and are known as small, mini strokes in no particular part of the brain. It occurs when a blood clot blocks an artery for a short time. The only difference between a stroke and TIA is that with TIA the blockage is transient (temporary). TIA symptoms occur rapidly and last a relatively short time. Unlike a stroke, when a TIA is over, there's no permanent injury to the brain. The Recovery is rather well. There's no way to tell if symptoms of a stroke will lead to a TIA or a major stroke. It's important to call 9-1-1
Hemorrhagic Stroke
Strokes caused by the breakage of a blood vessel in the brain are called hemorrhagic strokes, a bleed out. Hemorrhages can be caused by a number of disorders which affect the blood vessels, including long-standing high blood pressure and cerebral aneurysms. An aneurysm is a weak or thin spot on a blood vessel wall. These weak spots are usually present at birth. Aneurysms develop over a number of years and usually don't cause detectable problems until they break. There are two types of hemorrhagic stroke: subarachnoid and intracerebral.
In an intracerebral hemorrhage, bleeding occurs from vessels within the brain itself. Hypertension (high blood pressure) is the primary cause of this type of hemorrhage.
In a subarachnoid hemorrhage, an aneurysm bursts in a large artery on or near the thin, delicate membrane surrounding the brain. Blood spills into the area around the brain, which is filled with a protective fluid, causing the brain to be surrounded by blood-contaminated fluid.

What are the symptoms of a Stroke?
Everyone should know the symptoms of a stroke. There is an easy to remember acronym to remember the main symptoms
FAST
F – Facial weakness, especially on one side
A – Arm weakness
S – Speech is slurred, or the person is unable to speak
T – Time is critical, go to the hospital!
Besides the symptoms just mentioned, there are many more symptoms that can indicate a stroke. Since the brain controls all the body functions, a stroke can affect almost any body function. Any sudden change in your abilities could be a stroke.
Some of the most common other symptoms are
"HaVe BeeF"
H - Headache
V- Visual problems
B- Balance problems
F- Falling
If you think you having a stroke, tell the 911 operator and emergency workers so that they can get you help faster.
The faster you get to an emergency room, the faster Physicians can administer a drug to help lessen the effects of a stroke. This drug is called t-PA. This drug can be very effective in making strokes less severe.
However, in order to work, t-PA has to be given within 3 hours of the beginning of the stroke. Before t-PA can be given, you have to have tests to make sure that the treatment will be effective. In order to allow time for the whole process, you need to arrive in the hospital within one hour of the beginning of the stroke. Currently, only 3-5% of people who have strokes arrive at the hospital in time to receive t-PA.
