The Brain: Neurology
Neurology is the study of nervous system i.e.
brain. The brain is made up of billions of cells called neurons. The brain controls every
part of the body. There are messages to and from the brain for parts of the
body. The brain sends signals to the body parts and to the heart.
The Heart: Cardiology
Cardiology is the study of heart. The heart has
blood vessels to carry blood to and from it. The function of heart is to
circulate blood throughout the body. The heart sends blood to the brain through
a specific carotid
artery. There is a complex blood circulation in the
brain.
The Brain-Heart connection: Neurocardiology
Neurocardiology is the study of the interaction
between brain and heart. When the brain sends signals to the heart, the heart
beats that results in maintaining the blood pressure of the body. The nervous
system of the brain controls the heart rate. Once the blood pressure is
maintained, the heart sends back signals to the brain that the blood pressure
is maintained now. The brain then stops sending signals to the heart.
Heart disorder affects the brain:
If the heart fails to send back the signal
properly, the brain will continue sending signal to the heart to beat more and
more resulting in a high blood pressure. It means that the brain now is sending signals
continuously, heart is beating forcefully and the heart is not sending back a
stop signal to brain. It causes impaired heart function and high blood pressure.
This high blood pressure eventually results in brain dysfunction. It is now understandable
that brain and heart are interconnected.
The brain needs constant supply of oxygenated
blood. If heart muscle becomes weak, the blood pumping throughout the body and
to the brain is limited. When the blood circulation to the brain is limited it
causes problems with the electrical activity of the heart.
Brain disorder affects the heart:
The brain that is not functioning properly does
not generate proper neuron currents. It affects the electrical system of the
heart. Any change in heart electrical activity is due to unusual brain
electrical activity. Emotions that arise with in the brain affect heart rate. For
example, anger initiating from the brain can result in high blood pressure.
Conclusion
The heart sends signals to the brain. The brain
sends signals to the heart.
The disorders in brain activity can cause heart
failure. Loss of cells in brain also causes heart problems.
Heart neurologically
affects the brain. A
heart disease has a definite impact on brain function. The diseases that cause
heart malfunction affect the brain as well.
