Impaired of cerebral circulationdiagnoses
Defination
Is when there is a less oxygen and glucose reach your brain. This can cause brain damage and neurological problems
Risk factors
cerebral hypoxia
a stroke
cerebral edema
brain damage
disability
Pathophysiology
When a blood clot blocks the flow of blood in your cranial artery, a stroke can occur. As a result, the brain tissue in that area can die.
When that tissue dies, it can impair the functions that part of your brain normally controls.
For example, it can affect your speech, movement, and memory.
The degree of impairment you experience after a stroke depends on how much damage has occurred, as well as how quickly you get treatment. Some people fully recover from a stroke.
But many people have lasting disabilities or even die from strokes.
According to the American Stroke Association, stroke is the fifth leading cause of death among Americans.
Causes
many strokes is called multi-infarct dementia.
Narrowed or chronically damaged brain blood vessels.
Conditions that narrow or inflict long-term damage on your brain blood vessels also can lead to vascular dementia
Stroke (infarction) blocking a brain artery. Strokes that block a brain artery usually cause a range of symptoms that may include vascular dementia.
Nursing management
Maintain a healthy weight.
Maintain a healthy weight.
xercise regularly.
Avoid smoking.
Limit alcohol.
Treatment options
medications to treat narrowed arteries if this is the cause of symptoms
surgery in occasional cases with complete blockage or severe narrowing
A doctor can prescribe medication to:
thin the blood and prevent blood clots
reduce cholesterol
manage high blood pressure
Signs and symptoms
Confusion
Trouble paying attention and concentrating
Reduced ability to organize thoughts or actions
Decline in ability to analyze a situation, develop an effective plan and communicate that plan to others
Difficulty deciding what to do next
Problems with memory
Sudden or frequent urge to urinate or inability to control passing urine
Depression or apathy
Diagnoses
An ultrasound is often the preferred method for looking at the arteries, as it is noninvasive.
An MRI can show a clear picture of the brain. A doctor can recommend this test to check if a person has had a stroke or similar medical condition in the past.
Arteries do not usually show up in X-ray pictures. To see if an artery is damaged or blocked, a doctor can inject a harmless dye into an artery in the neck area.
