Transient Ischemic Attack (Mini Stroke) (Definition)
A condition where a blood vessel in the brain is temporarily blocked by a blood clot, causing neurologic symptoms, such as weakness in an arm or leg, or sensory changes. The symptoms are similar to a stroke, but are temporary, disappearing within minutes after the clot breaks apart. ...Read more
Do beta-blockers decrease cerebral blood flow? What meds increase cerebral blood flow through cerebral vasodilation?
Depends on blood flo: Pressure is the moving force getting blood to a body part including the brain. What counts is not the pressure but the quality and quantity of the blood getting to the brain. Obviously some pressures are incompatible with adequate blood supply but the answer depends on other factors such as arterial blockage, chronic hypertension, coronary artery disease, aortic valve problems. ...Read more
Bilateral high flow in common carotid artery and internal carotid artery with normal end diastolic velocity and no stenosis. Is this normal?
How high is high?: Increased flow without stenosis can happen if the cardiac output is very high or there is tortuosity if the arteries Generally don't worry until systolic velocity is over 200 cm/sec and even then it is probably ok with normal diastolic velocity why did you get the test? IF you are asymptomtic I would not worry too much ...Read more
Low blood pressure of 90/60 with a pulse of 90. Has Lewy body dementia and pulmonary emboli sim. Why would BP be low?
Hypotension: Of the three choices given hypotension makes most sense. Neither cva nor TIA generally produces hypotension. I would be concerned about meds, metabolic and cardiac issues. Needs a few labs to sort this out quickly unless this contradicts his advance directive. ...Read moreSee 1 more doctor answer
Tumors need nutrient: When tumors grow in the brain, they make new blood vessels (angiogenesis). These vessels are not normal compared to the non-tumor vessels. As a result, more blood flows into the tumor, which allows for more tumor growth. Since there is more flow, at any given time there is more blood volume in the tumor. Occasionally, there may be so much flow that it can shunt, or divert, flow from normal brain. ...Read more
