Below is a brief overview to describe types of strokes.  I am a visual learner, so I created some pictures to describe each type of stroke.  On The National Stroke Association’s website  http://www.stroke.org/site/PageServer?pagename=type at the bottom of the page, there are two animations to show hemorrhagic and ischemic strokes.  They also provide more in depth information regarding each type of stroke.

http://www.mind.ilstu.edu/usersSys/courses/courseHomepage.php?courseGUI=75  I highly recommend exploring this website after you review the different types of strokes.  It is a Virtual Stroke Lab that provides you with patient data, protocols and it is very interactive!  I have to admit I enjoyed the lab myself and after there are quizzes.

Picture
Hemorrhagic stroke occurs when a blood vessel in the brain bursts and blood bleeds into the brain.


Picture
Ischemic stroke occurs when blood is blocked from getting to the brain.


Picture
 
A Transient Ischemic Attack (TIA) is also known as a “mini stroke” because it happens for a small amount of time when not enough blood flows to the brain.
This is a great link to a handout that provides more information on Transient Ischemic Attack (TIA), it also explains the difference between TIAs and strokes.
