2. Intro
• The primary role of the brain is to send signals
to the body for motor function and respond to
receive signals received through the five
senses (sight, hearing, touch, smell, and
taste).
• The brain processes information both through
conscious thought, and unconsciously through
the nervous systems that control basic bodily
functions, like heart rate, breathing, and
temperature control.
3. causes
• Ischemia due to block g brain hemorrhage
• Most blood vessel is blocked.
• The blockage can be caused by a blood clot
that forms in the blood vessel (thrombosis) or
it can be caused by a clot or debris that floats
downstream (embolus).
• Blocked blood vessels
• Fatty plaque formation in the blood vessel
4. Risk factors
• family history
• smoking,
• high blood pressure,
• high cholesterol
• diabetes.
• Moreover, any condition that results in
stagnant blood flow and or clotting may result
in a TIA due to embolization of a blood clot.
Such conditions may include atrial fibrillation,
5. Symptoms
• The intensity and location of the blood
limitation to the brain will determine what
symptoms will occur as a result of a stroke or
TIA.
• Many people experience confusion, weakness,
and lethargy.
• If the loss of blood supply is in an area
supplied by the middle cerebral artery, a
classic sign may include weakness or paralysis
and numbness of one side of the body.
6. Dx
• History
• physical examination
• Assess mental status to make certain the
patient is alertand oriented.
• Check eye range of motion and facial
movement to evaluate the cranial nerves (the
short nerves that run from the brain to the
face and neck).
• Listen to the neck with a stethoscope to
detect abnormal sounds that may signal
7. Rx
• Treatment for a transient ischemic attack is
aimed at preventing a second stroke
• Treatment guidelines address a variety of
targeted goals.
• Antiplatelet therapy
• If the patient was not taking aspirin when the
TIA occurred, it usually is started at a dose of
325 mg per day.
