Brain Controls Blood Pressure
No: There is no certain brain part that controls blood pressure. Blood pressure control is multifacet mechanism but is primarily regulated by so called "baroreceptors" in the vessel wall. Those receptors are able to detect the degree of the vessel wall stretch and react to it accordingly. This triggers a whole cascade of other mechanisms of BP regulation. ...Read moreSee 2 more doctor answers
Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more
Feedback mechanisms: Many things impact bp. Neural stimuli and catecholamine release impact on heart rate and vasoconstriction. Renal blood flow and kidney function control internal fluid and salt regulation, as well as having an influence on hormonal activity and feedback on the nervous system. All of this helps regulate bp. ...Read more
Generally not a prob: Reducing blood pressure to normal levels should not affect proper brain perfusion except, perhaps, in two situations: orthostatic hypotension, where the blood pressure is fine when lying or sitting, but drops too low when stand up, and will get lightheaded, even pass out (too aggressive diuretic, parkinson's). 2nd, severe carotid artery diseas where lowering BP limits perfusion of blood to brain. ...Read more
Extremes always bad.: The underlying problem in most diseases is too little or too much of something. (comment: it is true of political and religious belief systems--the extremes are wrong, harmful, dangerous). If BP is too low, all the organs of the body will be under-perfumed, but most sensitive will be the brain, where function very dependent on o2/glucose. Very high BP will lead to strokes, small & big. Control. ...Read more
Is it possible for music to really improve health, reduce blood-pressure and help the human brain?
Music: There is a statistical probability for most things. Some music is calming and soporific. There is plenty of 'music' that isn't. I doubt some of the noise I hear blasting out of car speakers is anything but acoustic trauma. ...Read more
Depends on rate: If you have a sudden surge of pressure and a weakened artery in the bran it can have devastating results. If the pressure is elevated long term there are several mechanisms that occur to protect the brain. However anytime the diastolic BP is above 110 ( the lower #) the risk of stroke goes up ...Read more
Can you tell me how the brain's response causes the increase in blood pressure required during exercise?
I have a concussion and have been getting extremely angry the last few weeks while recovering. Does this raise my blood pressure and hurt my brain??
I have a concussion and have been getting really angry a lot more often, and my blood pressure gets really high. Can/does this raise in BP hurt brain?
