What is stroke?

Damage to brain. A stroke is generally term referred to impairment or loss of function of part of the brain. This happens when blood supply to that part of the brain is interrupted due to a blockage resulting from plaque build up and/ or blood clot. Also rupture of blood vessel causing bleeding in the brain can result in stroke.
See below. Sudden onset of neurological symptoms (weakness, numbness, trouble speaking or understanding, vision loss, imbalance, incoordination, slurred speech) that has results from a blood vessel problem to the brain. This can be from a clot that blocks off blood going to the brain or from a ruptured blood vessel in the head. The gold standard for diagnosis is actually based on CT or MRI scan of the brain.
Blood flow. A stroke is an alteration of blood flow to the brain resulting in a loss of tissue and possible loss of function. It can be categorized in many ways but ultimately is a disease event related to the cerebral circulation. Blockage and rupture of arterial components are commonly described but venous pathologies can also cause stroke.

What is stroke?

Blood flow problem. Stroke is a problem with blood getting to brain tissue. It can be from blood vessels being clogged ("ischemic"), or from blood leaking out because of high blood pressure, blood disorders, trauma, etc. Either way, the tissue does not get enough oxygen and it gets injured. Eventually it will die if blood flow is not restored fast enough. Read more...

What causes strokes?

Cause of strokes. Strokes are caused by insufficient blood and oxygen flow to the brain. The common types of stroke are ischemic stroke (when blood flow is impeded) and hemorrhagic stroke (when a broken blood vessel leaks blood into the brain). Most strokes are related to high blood pressure, smoking, diabetes mellitus, high blood cholesterol and atrial fibrillation. Read more...

What does stroke mean?

Brain attack. 2 kinds of stroke: ischemic or hemorrhagic. Ischemic (either thrombotic or embolic) is like a clogged drain in your house. Hemorrhagic is like a burst pipe. In either case, you don't get water flowing where you need it. Same w/stroke - you lose blood flow to vital areas in your brain (are there non-vital areas?). Without blood flow, brain dies. So if you think you're having a stroke, call 911. Read more...
Brain function loss. I assume you mean cerebral stroke (brain). There are heat strokes, etc. Brain stroke refers to a rapid loss of brain function. This can be due to loss of blood supply to the brain tissue or a brain bleed (hemorrhage). A transient loss of blood supply whereby the brain function is immediately restored when the blood supply is restored is called a mini stroke, ie, "transient ischemic attack". Read more...

Can any docs elaborate what a stroke means please!?

Yes. A stroke occurs when a part of the brain lacks blood flow or when a blood vessel bursts and spills blood is an area of the brain. This causes the affected part of the brain to die. The good news is that in many people the areas adjacent to the stroke take over and function recovers. Recovery depends on many factors including the size of the stroke. Rehabilitation helps maximize recovery. Read more...

Help docs! I'm trying to find out what causes strokes in teenagers?

Good question. The most common cause of strokes in the teenage population is illicit/recreational drugs. This can lead to intracerebral hemorrhages and vasculitis (inflammation of the blood vessels. Some natural causes of stroke include arteriovenous malformations (congenital tangle of blood vessels), and moyamoya(development of arterial narrowing of large brain vessels). Read more...

What is stroke speech therapy exactly?

A type of treatment. Stroke usually impairs functions of the pharynx and laryinx (voice box) as well as soft palate and tongue in that it pertains to swallowing and speech.
