I will give some more information on strokes which are now termed "brain attack":
Thrombus clot, most common in the middle aged and elderly. It causes ischemia/lack of blood supply and lack of oxygen to brain tissue and results in
congestion and swelling/edema in the brain. The swelling will produce more symptoms than the clot itself, and symptoms will go away when the swelling
goes down. Symptoms from the swelling includes loss of functioning of which I have details further down this post.
Embolism or traveling clot, which is the second most common cause. The embolism will move around until it occludes the blood vessel. Embolisms
include a fragment of a clot, tumor, fat, bacteria or air. These occur in any age group, especially if they have rheumatic heart disease,
endocarditis, A-fib and cardiac arrhythmias, post op open heart surgery, and post traumatic valvular diseases. The stroke occurs within 10-20 seconds
of the occlusion and without warning.
Hemorrhage, which can occur suddenly at any age. This is usually related to hypertension or an aneurysm causing a sudden rupture of a cerebral artery,
which reduces the blood supply to the areas served by this artery. Blood will accumulate in the brain and start compressing brain tissue causing more
Premonitory or the warning signs....drowsiness, dizziness, headaches, confusion. These symptoms are not specific and most don't think they are having
Generalized....headache but more severe and persistent, vomiting, mental impairment, seizures, stiff neck, fever, disorientation and coma.
Other more specific signs resulting from the stroke impacting the cranial nerves....
visual impairments such as blindness in one eye or half of each eye, either the same half or opposite halves
difficulty speaking, slurred speech
difficulty with swallowing
loss of taste
loss of smell
numbness and tingling
a decrease in coordination
With a TIA or transient ischemic attacks, which are mini strokes caused by micro sized clots being stuck in smaller vessels like arterioles, these
cause temporary symptoms of eye blurriness, speech difficulties, temporary blindness on the same side which the TIA is occurring, tremors, weakness or
numbness on the opposite side where the TIA is occurring, and dizziness. These TIA's are warning signs that a larger stroke can happen. The clot can
get dislodged when the artery spasms and then circulation can return and the symptoms will stop. These are not to be taken lightly!
TIA's are the least severe. A progressive stroke or evolving stroke will start out with slight neurological impairments like the ones I listed and
will continue to get worse within 24-48 hours. A completed stroke will be as bad as its going to get when it happens.
I know this is a more comprehensive list but I at least wanted to expand on the information already given. It is extremely important that anyone
having any type of impairment like these described been seen immediately!!!
Time is extremely important and clot buster medication must be given within 3-4 hours when symptoms start appearing. This medication can help save the
person having the stroke from permanent paralysis!
Also, the medical tests that are usually needed are MRI or CT scan which will show which type of stroke it is or if its a tumor, angiography which
will show the outline of blood vessels, and an EEG.
Hope this helps anyone that wanted to know more. BTW I just graduated from an RN school two weeks ago and am testing for my state license in a couple
of weeks, if anyone was curious about my medical background.
