Secondary NPH can affect persons of any age and occurs due to conditions such as subarachnoid hemorrhage, meningitis, brain surgery, brain radiation, or traumatic brain injury. [16] These conditions are thought to lead to increased inflammation of the arachnoid granulations , which further leads to decreased CSF reabsorption and therefore ...
The location of the shunt is determined by the neurosurgeon based on the type and location of the blockage causing hydrocephalus. All brain ventricles are candidates for shunting. The catheter is most commonly placed in the abdomen but other locations include the heart and lungs. [10] Shunts can often be named after the route used by the ...

And PC-MRI gradually became the most often used sequence to evaluate the CSF flow pattern in patients with NPH in relation to the cardiac cycle. [4] Figure 1. The MRI of a patient with normal pressure hydrocephalus (NPH) showing pulsations of CSF with heartbeat is shown in this moving image.
The constant communication between the heart and the brain have proved invaluable to the interdisciplinary fields of neurological and cardiac diseases. [4] The fundamental understanding of the communication between the heart and the brain via the nervous system has led scientists towards an understanding of its elaborate circuitry.
The human brain is about 60% fat by weight, far more than any other organ. Essential fatty acids, such as omega 3s, are key to the strength and performance of the brain’s cells.
