Molly Lynch was complaining of yet another headache and her doctors were not sure if was due to her medical shunt or not. Her doctor reached out to Dr. Joshua Medow, a neurosurgeon with the University of Wisconsin-Madison Hospitals. Dr. Medow knew Molly’s case well and although the other doctors thought he was crazy for wanting to fly her by helicopter immediately to the UW-Hospital, Dr. Medow knew it was only a matter of minutes to hours before she blew a pupil form too much pressure in her head. Unfortunately, when Molly landed she would died from the pressure and blew a pupil before she was rushed to the operating room.
“Now imagine,” said Medow, “if I had a device and I could have known what was happening leading up to it, Molly would

Dr. Medow has watched numerous children be rushed into the emergency room due to a malfunction with their medical shunt. Side effects associated with the shunts range from headaches to vomiting to sleepiness can lead to comas, strokes, a blown pupil and even death, according to Hydrocephalus Association.
This pressure sensor implant will be used on patients with hydrocephalus, a condition that causes excessive fluid within the brain, as well as patients with brain injury or other head trauma as it will wirelessly measure intracranial pressure giving these patients a therapeutic treatment that can be treated permanently, rather than periodically and repetitively.
Dr. Joshua Medow, the brains behind the device, is an associate professor of neurosurgery and biological engineering at the University of Wisconsin-Madison. His advanced educational background in computer science, biomedical engineering, and neurosurgery allows Dr. Medow to use the best human computer, the brain to solve

This blood, the fluid, is being inserted into the skull with every heartbeat, every second. Once the brain has extracted the necessary oxygen and gotten rid of the carbon dioxide from the fluid, there is a drainage system in place that drains the fluid in other parts of the body. This must be done or else the pressure within the skull gets too high. However, in one in 500 people the drainage system does not work right, therefore, building up pressure, crushing the brain and eventually killing them, according to Project Brain Drain.
A medical device called a shunt has been developed by neurosurgeons that can relieve this drainage problem, however, it is quite invasive. A shunt is placed directly into the skull and is a one-way valve that drains the excess fluid. This device works fine except that this flow tends to pull debris into the tube and in about 40% of the cases it plugs up. From this, many patients with the shunt develop symptoms such as headaches, vomiting, and neurological problems and once they develop these symptoms doctors have no idea whether theses symptoms have stemmed from an illness or a build up in pressure, which could be deadly. “One of the problems is we don’t even know the pressure that we are dealing with and we surely don’t know if the mechanical valves meet the requirements of that particular patients pressure needs,” said

After your shunt is placed, it is important to have the following information with you:
Lewis Blackman was a fifteen year old boy whose death was triggered by the numerous errors caused by his healthcare professionals. He was suffering from a Pectus Excavatum, a non-life threatening condition. His mother, Helen Haskell, was attracted to an advertised surgery that boasted all the benefits of the procedure without proclaiming the risks. He checked into the Medical University of South Carolina Children’s Hospital on November 2nd, 2000, to undergo this “safe and minimally invasive” procedure. Complications arose following the surgery, but they were not communicated effectively within the nursing co...

Once the rat experiment finished, he further tried to optimize his technology. Those implants were made after a membrane called Dura mater which covers the spinal cord and brain. The next step was to implement it on humans. The implementation was done on a man who was partially paralyzed because of an injury to his spinal cord 5 years before the implant. Those electrodes were implanted on the surface of the lower spinal cord just below the affected area.
There has yet to be a cure for Hydrocephalus, but there are indeed treatments. Although, not many advances have been made in preventing, healing, or moderating Hydrocephalus. In fact, the device currently used as the dominant treatment was pronounced fifty years ago and has had the highest failure rates in comparison to any surgical remedy. Introducing said regimen, The National Institute of Neurological Disorders and Stroke (2013) explains, “Hydrocephalus is most often treated by surgically inserting a shunt system.” This operation revolves around the embedding of two catheters along with a valve. The valve influences the flow of CSF to generate an increasingly normal rate and direction. As an alternative, there is a procedure labeled as a ventriculostomy in which a hole is made in the underlying area of a ventricle or in between the ventricles. This functions as a funnel for the CSF to exit the cranial area. These methods are customarily permanent and must be monitored
Surgical evacuation via craniotomy is often considered in patients with an acute SDH thicker than 5 mm (as measured with axial computed tomography [CT]) and who have any neurologic signs, such as lethargy or other change in mental status, or a focal neurologic deficit. This patient has none of these findings, with a normal Glasgow score. Given the CT scan results showing stability, close observation is probably the most
These further conditions are thought by researchers to have been generated complications from the impaired cerebellum of the brain. (Dandy-Walker Malformation Presenting with Psychological Manifestations) Another complication due to Dandy Walker Syndrome is hydrocephalus; a build up of cerebrospinal fluid in the brain’s ventricles. (Dandy-Walker Malformation) Hydrocephalus also causes additional swelling to the head, also a double sign for hydrocephalus and Dandy Walker Syndrome both. Patients that have both Dandy Walker Syndrome and hydrocephalus have a more common combination of complications and present more symptoms of the overall

It is primarily aimed at the patients who suffer from ailments like where people could have lost the ability to walk for years but have yet recovered through this method, or children with learning disorders, Parkinson’s disease etc. who can be treated through simple approaches. There are many cases where children suffering from autism, and other such illness of the like and the advent of neuroplasticity offers hope and recovery to these people and children.
There is also the matter of the harmful effects of trepanation. It could lead to infection, foreign substances entering the brain cavity, incorrect blood flow, and other negative results. The most obvious problem is that, if done incorrectly, a trepanation could quickly become an accidental lobotomy. If the drill were to slip and go too far, it could lead to brain damage, or death.

...tracranial pressure from brain edema. Interventions include administering osmotic diuretics, maintaining partial pressure of carbon dioxide, and positioning to avoid hypoxia. Other treatment measures include elevating the head of the bed to promote venous drainage and to lower ICP.
Like all organs, the brain needs the oxygen and nutrients provided by blood to function properly. If the supply of blood is restricted or stopped, brain cells begin to die. This can lead to brain injury, disability and possibly death.
The brain works with electrical signaling between neurons. Neuroscientist Karl Deisseroth oversaw the implantation of a device that sends electrical signals. The device sends impulses to the vagus nerve which is carried to a structure in the brain that regulates mood. ("Lighting the Brain"). The research and device provided opportunity for more techniques and methods for sending these signals in hopes of treating mental
