The brain is a complex organ that controls various body functions.
If a stroke occurs and blood flow can't reach the region that controls
a particular body function, that part of the body won't work as it
should.
When part of the brain dies from lack of blood flow,
the part of the body it controls is affected. This is why a stroke
can cause paralysis, affect language and vision, and cause other
problems.
If the stroke occurs toward the back of the brain,
for instance, it's likely that some disability involving vision
will result. The effects of a stroke depend primarily on the location
of the obstruction and the extent of brain tissue affected.
