Cerebrovascular accident: The sudden death of some brain cells due to lack of oxygen when the blood flow to the brain is impaired by blockage or rupture of an artery to the brain. A CVA is also referred to as a stroke. Symptoms of a stroke depend on the area of the brain affected.
People also ask, which would most dramatically impact the levels of free radicals in one body?
Filipovsky talks about “free radicals” and how their buildup produces tissue damage. … Which would MOST dramatically impact the levels of free radicals in one’s body? Consuming antioxidants like vitamin E. You just studied 25 terms!
Keeping this in consideration, when older adults are asked to respond to an ambiguous question you can expect group of answer choices?
When older adults are asked to respond to an ambiguous question, one can expect: slower response rates.
What is difference between TIA and CVA?
Rupture of an artery with bleeding into the brain (hemorrhage) is called a CVA, too. If the symptoms are temporary, usually lasting less than an hour without permanent brain damage, the event is called a transient ischemic attack (TIA).
What are the 5 warning signs of a stroke?
The five warning signs of stroke are:
- Sudden onset of weakness or numbness on one side of the body.
- Sudden speech difficulty or confusion.
- Sudden difficulty seeing in one or both eyes.
- Sudden onset of dizziness, trouble walking or loss of balance.
- Sudden, severe headache with no known cause.
What vitamin protects cells from free radicals?
Antioxidants — such as vitamins C and E and carotenoids, which include beta-carotene, lycopene and lutein — help protect healthy cells from damage caused by free radicals.
Is oxygen responsible for aging?
Oxidative stress causes cells and entire organisms to age. If reactive oxygen species accumulate, this causes damage to the DNA as well as changes in the protein molecules and lipids in the cell. The cell ultimately loses its functionality and dies. Over time, the tissue suffers and the body ages.
How do free radicals damage a cell?
Free radicals can cause damage to parts of cells such as proteins, DNA, and cell membranes by stealing their electrons through a process called oxidation.
What is the best treatment for stroke?
An IV injection of recombinant tissue plasminogen activator (tPA) — also called alteplase (Activase) — is the gold standard treatment for ischemic stroke. An injection of tPA is usually given through a vein in the arm with the first three hours.
What is the medical term for CVA?
Cerebrovascular accident (CVA) is the medical term for a stroke. A stroke is when blood flow to a part of your brain is stopped either by a blockage or the rupture of a blood vessel.
What are the two types of CVA?
Types of Stroke
- Ischemic stroke.
- Hemorrhagic stroke.
- Transient ischemic attack (a warning or “mini-stroke”).
