What are the types of stroke?

Stroke can be caused either by a clot obstructing the flow of blood to the brain (called an Ischemic Stroke) or by a blood vessel rupturing and preventing blood flow to the brain (called a Hemorrhagic Stroke).¹ A TIA (Transient Ischemic Attack), or "mini stroke", is caused by a temporary clot.²

What is Acute Ischemic Stroke?

Acute Ischemic Stroke (AIS) is the most common type of stroke.¹ It accounts for about 87 % of all strokes.³

AIS occurs when a clot blocks a blood vessel and stops blood from flowing as it should to the brain.³

In fact, if a blood vessel in the brain is narrowed or blocked, the resulting lack of blood and oxygen can cause irreversible brain damage in only minutes.⁴

For every minute a large stroke is untreated, the brain loses 1.9 million cells. This is often summarized by the phrase, “Time is brain.”⁵

What is a Brain Aneurysm?

A brain aneurysm is a weak, bulging area in an artery due to a weakness in the vessel wall.

Unruptured aneurysms may have a risk of rupture resulting in blood flow into the surrounding area of the brain. The annual rate of rupture is approximately 6 - 10 per 100,000 people.

Most unruptured aneurysms don't cause symptoms; instead, they only cause symptoms when they rupture and bleed.

What is Chronic Subdural Hematoma?

Subdural hematoma, or SDH, occurs when a hematoma, or pool of blood, forms beneath the brain’s outer covering.^8,9

The most common cause of chronic SDH is thought to be a combination of any kind of head injury, even if it’s minor, and chronic inflammation. Other known risk factors include age 60 and older, seizures, alcoholism, chronic liver disease, chronic kidney failure, blood disorders, and drugs that help prevent blood clots, such as anticoagulant or antiplatelet therapy. Given these risk factors, chronic SDH tends to occur more often in the elderly.^9,10

Patients may have a variety of symptoms depending on the size and location of the SDH, including nausea, vomiting, seizures, and stroke-like symptoms such as headaches, dizziness, confusion, limb weakness, and trouble walking, speaking, or swallowing.

SDH are typically treated with a medication. Depending on the severity of symptoms, surgery or other procedures could be recommended.⁹
