Celebral Blood Flow Restriction
I would start: With cta of the head and neck. ...Read more
Echo saging of the body of AMVL, normal blood flow, trivial MR. Restrictions? Can I live normal and do everything? Only symp skip beats waning/waxing
MVP: Such mild prolapse of the mitral valve is common and should not impact your physical activities, although atrial irritability certainly may occur. You could have a treadmill exercise stress test to see if strenuous physical exertion precipitates significant cardiac rhythm disturbances. Passing such a test will give you peace of mind. I recommend echocardiography every year or two to monitor mvp ...Read more
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
Not exactly: The flow to the anterior cerebral starts at the heart, goes up the ascending aorta, to carotid arteries which reach the Circle of Willis, and go to anterior cerebral, middle cerebral and posterior cerebral arteries. Anterior communicating can be viewed as a bridging collateral. ...Read more
Is there anyway to see if cerebral blood flow is reduced when standing? Got dysautonomia and suspect cerebral vasoconstriction is too excessive
Dysautonomia: Dysautonomia syndrome causes different symptoms alleviated by avoidance of stimulants, ensuring hydration, using magnesium, vitamin D & omega fish oils (www. Cardiamin. Com, use code: CMC), low dose beta blockers e.g. propranolol 5 to 10mg 2 to 3 times daily and SSRIs e.g. citalopram 5 to 10mg daily. Read Dr. Ronald Hoffman’s MVP book (www. Amazon. Com) and visit www. Dysautonomiainternational. Com. ...Read more
Studies show caffeine reduces Cerebral BloodFlow 27-40%... does this mean caffeine is damaging brain cells? Why not? Reduced blood flow is NOT good!?!
If that were: The whole truth, caffeine would not be the most widely used psychoactive agent on Earth. Caffeine also enhances alertness, enhances mental focus and improves score for all comers in tests of performance and cognition. So, this is what happens when you take one isolated physiologic response and try to then conclude something more complex about cell function, especially the brain. Neurobiology=??? ...Read moreSee 1 more doctor answer

Best diagnostic to detect vasoconstriction and reduced cerebral blood flow? Transcranial doppler?
Do beta-blockers decrease cerebral blood flow? What meds increase cerebral blood flow through cerebral vasodilation?
What R the lasting effects of a years worth of reduced cerebral blood flow due to vasoconstriction? Does the lack of proper CBF result in cell death?
Cancer and blood flo: Many cancers elaborate factors that enable the growth of new blood vessels. In this way they gain an advantage in growth. When seen clinically on radiologic tests, this is a marker of malignancy and agressiveness, especially in the brain where low grade tumors only do this to a mild degree. Some cancers are treated by agents that interrupt this process, hoping to "starve" them of nutrients. ...Read more
Please explain what it means when there is increased cerebral blood volume and blood flow in a brain tumor?
Is there any drug that selectively increases cerebral blood flow but does not effect systemic blood pressure or heart rate?
Unlikely: I am not aware of such a drug. I am not sure why you might want this. There is not a specific way to do this and many drugs are able to cross the blood brain barrier. See your doctor if you have any symptoms you cannot complain. ...Read more
