Blood brings oxygen
and nutrients to brain cells. A stroke
occurs when blood flow is interrupted to
part of the brain. Without blood, brain
cells quickly begin to die. Every
second that the brain is deprived of
oxygen, 32,000 brain cells die.
Although 85% of stroke victims are
eligible for the clot busting drug,
tissue plasminogen activator, or tPA,
only about 5% of patients actually
arrive in the hospital within the
maximum time of application, which is
four hours.
Stroke
can affect different people in different
ways. It depends on the type of
stroke,
the area of the brain affected and the
extent of the brain injury.
Stroke causes many
physical and emotional side-effects.
Stroke is the number one cause of
serious permanent disability.
Below are listed
some of the more common disabilities
that stroke can cause:
 |
lack of sensation
|
 |
partial or
total paralysis (hemiplegia) |
 |
bowel and
bladder control
|
 |
inability to walk and problems
with coordination and balance
(ataxia)
|
 |
vision
neglect
|
 |
sexual
ability
|
 |
loss of
balance
|
 |
loss of
muscle tone
|
 |
spasticity |
 |
central
pain syndrome (thalamic pain) |
 |
problems with speech and
understanding language (aphasia)
|
 |
shortened
retention spans and difficulty
learning new information |
 |
inability
or difficulty with swallowing |
 |
impaired ability to do math or
to organize, reason, and analyze
items |
 |
loss of
short-term memory
|
 |
behavioral changes such as lack
of concern about situations,
impulsivity, inappropriateness,
and depression
|
 |
coma |
 |
death |
 |
... and
many more side-effects not
mentioned

Stroke commonly
affects the emotions. It can cause
lack of control of your emotions and an
improper response may happen at
inappropriate times. This is
called the
pseudobulbar
affect. Pseudobulbar affect (PBA),
also known as
emotional lability, is a distinct
neurologic disorder that causes sudden
and unpredictable episodes of crying,
laughing, or other emotional displays.
The
statistics about stroke are
unbelievable! Every 45 seconds
someone suffers a stroke. Over
750,000 people in the United States
experience a stroke every year. Stroke
kills nearly 160,000 people each year.
Stroke is the third leading cause of
death in this country. Nearly 30%
of those who suffer a stroke are under
the age of 65. They affect men
nearly as often as women and blacks
almost twice more often than whites.
Stroke requires
immediate medical attention. The sooner
treatment is received, the better the
chances of survival. Because of improved
treatment methods, less than three out
of ten people who suffer a stroke die
from the experience.
Thrombolytic therapy is the use of
drugs to break-up the clot that is
causing the disruption in blood flow to
the brain.
It is crucial,
imperative, and very important that you
immediately go to the hospital when you
first notice the
warning signs
of a stroke. The length of time between
the first warning signs and the time you
get to a hospital may be the difference
between a good or poor outcome. Patients
who present to the hospital within 3
hours of the first sign of a stroke have
the possibility to receive
Tissue Plasminogen Activator
(tPA).
There are many
factors that determine whether or not a
patient is able to receive
thrombolytic therapy. One of these
factors, that you have control of, is
the amount of time between the onset of
symptoms and presentation to the
hospital. If you get to the hospital
within the 3 hour time frame and the
doctor determines you are able to
receive this clot-buster, you may have a
better recovery.
