Clinical Manifestations
A sudden, severe headache that appears without warning.
What is an acute-onset headache?
Inadequate perfusion in the posterior circulation can compromise this structure, which integrates sensory input for balance and coordinated movement.
What is the Cerebellum?
A test that uses high-frequency sound waves to visualize soft tissues, particularly an artery in the neck.
What is a carotid ultrasound?
A medical procedure that involves using a balloon to open an artery. It may precede a stent placement.
What is an angioplasty?
The age and gender who have the highest risk of this condition.
What is a male over the age of 55?
Interruption of blood flow to cortical language or motor areas disrupts ionic gradients, leading to rapid failure of these two essential neuronal processes.
What are action potential propagation and synaptic transmission?
This scan uses X-ray imaging and contrast dye that may reveal an arterial plaque, particularly in the neck.
What is a carotid angiogram?
A type of medication that inhibits the production of LDL cholesterol by the liver, reducing the buildup of plaques in arteries.
What are statins?
The number one risk for this condition, which damages arterial walls over time, promotes plaque formation, and can also lead to heart attack and stroke.
What is hypertension?
A temporary problem with vision such as blurriness, partial blindness, or a sudden dark curtain over the eye.
What is transient vision loss?
Dysfunction of this vascular layer can promote clot formation by exposing subendothelial collagen and triggering platelet activation.
What is endothelial injury or endothelial dysfunction?
A scan that uses X-rays to create cross-sectional images of the body. It yields a negative result with the condition of interest.
What is a computerized tomography (CT) scan?
Choosing to eat foods limited in fat, cholesterol, and processed sugar to promote a healthy lifestyle with minimal plaque buildup.
What is a heart-healthy diet?
An illicit drug that significantly increases the risk of this condition, due to vasoconstriction, hypertension, arrhythmias, and contributions to atherosclerosis.
What is cocaine?
A brief difficulty speaking or understanding language, sometimes described as "words that won't come out right."
What is Asphasia?
A sudden mismatch between cerebral supply and metabolic demand leads to this reversible cellular state before permanent injury develops.
What is neuronal ischemia without infarction?
A medical imaging technique that uses magnets and radio waves to create images of soft tissues in the body. It yields a negative result with the condition of interest.
What is magnetic resonance imaging (MRI)?
Drugs used to treat hypertension.
What are antihypertensives?
An interruption of blood flow to the brain resulting in the death of tissue. The condition in question is commonly a warning sign of this.
What is a stroke?
A sudden loss of strength or feeling on one side of the body, often affecting the face, arm and leg.
What is weakness or numbness?
A brief reduction in perfusion to a focal region of the brain is most commonly cause by this type of vascular event.
What is transient arterial occlusion?
Problems with balance, eyes, face, arms, and or speech.
What are stroke-like symptoms?
A medication that prevents thrombosis.
What is an anticoagulant?
The medical specialty that leads the care of patients experiencing this condition.
What is neurology?
