Question 1

what is stroke?

Accepted Answer

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.

Question 2

what is stroke?

Accepted Answer

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.

Question 3

what is dry stroke?

Accepted Answer

Ischemic: Dry stroke is a misnomer used for ischemic stroke that means interruption of blood supply to the brain due to a clot or an embolus. On the other hand, a hemorrhagic stroke (bleeding into the brain) will be an example of the wet stroke. 
See dr. Levine's brief discussion for further details - http://www.Youtube.Com/watch?V=_djquiubh0e.

Question 4

what causes strokes?

Accepted Answer

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.

Question 6

what is a dry stroke?

Accepted Answer

Ischemic: A dry stroke is due to a cut off or reduction in circulation to a portion of the brain, usually due to closure of a blood vessel from a blood clot.  This is different from a "wet stroke" in which a blood vessel break or is disrupted, causing bleeding or hemorrhage into the brain.

Question 7

conmon age for stroke?

Accepted Answer

Elderly . . .: Old age is typically defined as 10yrs older than my/your current age. So common age for stroke is in older folks. However, a recent study suggests that risk for stroke in younger patients is increasing due to great risk factors as we are not taking good care of ourselves. These risk factors include high blood pressure, high cholesterol, diabetes, obesity & smoking, etc. Go see your family doc.

Question 8

what does stroke mean?

Accepted Answer

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.

Question 9

can weed causes strokes?

Accepted Answer

Minimal data: There's a report of binge smoking in adolescents who were irregular users of mj, having cerebellar strokes because of the binge. 2 died. There is a report that smoking mj is protective like aspirin. But mj causes vasoconstriction & fluctuations in arterial spasming that may contribute to a stroke in a susceptible person. No good data either way.  Best not to smoke anything and mitigate your risks.
